1 Introduction

1.1 General remarks

With the function block package 8, it is possible to transmit data serially with the PLC 135 WBvia the CP 315/373.

Only the PLC can initiate data input or data output. Implementation is effected on the basis ofthe existing computer link function, configurable user frames (see the figure ”Basic structure”below).

1 Introduction 02.92

1.2 Procedures

1.2 Procedures

The expanded number of procedures as well as protocol-independent communication enableuniversal application of the active serial interfaces (CP 315/373).

The following procedures can be used with this package:

• LSV2• 3964 R• XON/XOFF (character-controlled procedure)• RTS-LINE (line-controlled procedure)• TRANSPARENT (loadable procedures; which can be implemented in PLC)

The procedures are parameterized in the CP with the aid of the configuration software SINPS315.

1.3 Package structure

The blocks are structured in such a way that, in spite of different data handling, FBparameterization is very similar and easy to accomplish.

The essential differences are found in the acknowledgement procedure of input/output data.Please bear in mind that on data input a different signal behaviour is required. This affects boththe selected procedure and the size of the useful data DB provided by the user.

The remote station can only transmit data to the SINUMERIK on its own initiative after theinterface has been initialized by the PLC. Initialization, management of the CP interfaces anddata handling are performed by package 8.

The two function blocks to be parameterized support handling of a maximum of foursimultaneously active transfer jobs in each direction of data transfer.

There is a different function block for each direction of data transfer. The user calls FX 26 fordata input and FX 27 for data output (see figure ”Package structure”).

The user must coordinate the initiation, termination and, if necessary, abort of transmissionand must provide the useful data (for output) and receive them (for input). All internal controlsequences and data transfers are controlled by package 8.

02.92 2 Data Input Function

2.1 Description of data input function

2 Data Input Function

2.1 Description of data input function

The data received by the CP is transferred to the COM from the DPR with a max. frame lengthof 244 bytes. The COM transfers the frame into one of the 6 input buffers of the MPR. Thecomputer link operating system receives this data and stores it in the parameterized usefuldata DB. In DB 101, data byte ID 7 assigned to user interface input indicates what type offrame it is. The following entries are permissible:

ASCII "E"= Single frame"N"= Initial frame"M"= Subsequent frame"L"= Terminating frame

ID byte 8 contains a number assigned by the CP to the frame, the frame number.

Data transmission to the user is executed depending on the selected procedure and the sizeof the useful data DB.

The user can select three different types of data handling. These types are described in detailin the following three subsections.

The signal ST (start) initiates the transmission job. The interface for the data to be received isassigned the required addressing data (e.g. destination DB, destination DW).

If the CP interface is defined as a slave, the start is initiated automatically by the functionblocks. For the XON/XOFF procedure, the XON character is sent. The CTS line is set activefor the RTS/CTS procedure.

The function block DAT-EIN executes a series of validity checks before assignment of theinterface. If one of the requirements is not met, the interface is not assigned; the user isinformed on the cause of the abort with the signals FEHL (error) and F-NR (error number).

At the same time the job trigger is reset.

The CP interface is not assigned if

• User interface (UI No.) not permissible,• Job number <1 or >4,• Useful DB/BX is not available or DB 0,• Useful DB/DX set up with a length <1 frame (246 bytes).

The interface is enabled when the user interface has been parameterized and enabling hasbeen triggered.

The interface is enabled if:

• The user resets the ST (start) signal.• The PLC wait cycles have elapsed after receipt of the last frame sequence and if no new

frame sequence is running.

The user can choose between three different data handling types. These are described indetail in the following subsections.


2 Data Input Function 02.92

2.1.2 Unsorted data transfer

2.1.1 Unsorted data transfer

Precondition

The useful data DB is set up with a length which is at least the length of a frame (246 bytes).Procedure-independent, MD bit sorting on/off=0. CP is defined as a master with respect to theI/O unit.

Handling

The frames are transferred to the useful data DB in the sequence in which they are read in theCOM/PLC transfer buffer (by the computer link operating system not by the function blockFB=DAT-EIN). This type of data handling does not guarantee that the frames are transmittedto the useful data DB in the correct sequence. This must be ensured by the user himself bymeans of the frame number. The current frame number can be obtained from the parameterB-No. Please note that the frame sequence is not necessarily terminated with the AENDsignal (data input terminated). The remaining frames must still be fetched.

If the frame sequence is not terminated, but the useful data DB is full, the signal AFOR(continuation signal) is set. The user must interpret the data and must set the signal ANST(initiation enable) as an acknowledgement for further transmission. This handshake is repeateduntil all frames have been fetched.

In the case of a single frame, the signals AEND (data input terminated) and AFOR(continuation signal) are set directly; otherwise, only AFOR is set. Every single frame must beinterpreted by the user and enabled via the signal ANST (initiation enable).

Advantage: No internal data buffering; small useful data length on user side; high datatransfer rate.

Disadvantage: User must sort the frames.

2.1.2 Sorted data transfer

Precondition

The useful data DB is set up with a length which is at least the length of a frame (246 bytes).Procedure-independent, sorting MD bit on/off=1. CP is defined as a slave with respect to theI/O unit.

Handling

The computer link operating system transfers the frames into a data buffer which is assignedto the job number. The FB checks by means of the frame number whether the frameconforms to the sequence. If this is the case, the frame is transmitted directly to the usefuldata DB. Otherwise, the frame is buffered and transferred only when "its turn comes". If theframe sequence is terminated with an "L" frame, the AEND signal (data input terminated) isset.

If the frame sequence is not terminated, but the useful data DB is full, the AFOR signal (continuation signal) is set. The user must interpret the data and must set theANST signal (initiation enable) as an acknowledgement for further transmission. Thishandshake is repeated until the terminating frame has been sent.

The files can only be transferred in a useful data DB. When using this data handling method,bear in mind that an increased storage capacity of 370 bytes per job is required.




2.1.2 Sorted data transfer

Advantage: The user must not sort the frames, simple data handling.

Disadvantage: Internal data buffering, additional user DB memory, low data transfer rate.

2.1.3 Single frame transfer

Precondition:

You must configure the CP as a slave and use a character/line-controlled XON/XOFFprocedure or a RTS line. Set up the useful data DB to be at least the length of a frame.

MD bits: CP master/slave=0; Sort On/Off=1.

Every single frame is transferred by the user with an end identifier.

Handling

In this mode, the input data is transferred to the user only within the size of a frame. Theselected procedure guarantees that the data is transferred in the correct sequence. The CPdisables the interface after having received a frame and waits for the PLC acknowledgement.The acknowledgement is effected by means of the internal frame "Data Start". The PLC inturn generates this frame after the user has evaluated the data; the user initiates dataevaluation by setting the signal ANST (initiation enable).

Advantage: None

Disadvantage: Block sortings and no internal data buffer, low data transfer rate.

2.2 Frame sequence error

One frame might overtake another during data transfer. The block DAT-EIN can coordinate upto two such events. If more than two should occur, the block outputs error message 3406 andterminates the job.



2.3 Input sequence

2.3 Input sequence

a) The user provides a useful data DB.b) The user starts the block.c) The block assigns the set interface and evaluates the acknowledgement signal.d) If the acknowledgement is positive, the useful data is transmitted via the interface and an

acknowledgement then sent to the remote I/O unit.e) Then the user enables the interface.f) The user then receives an acknowledgement from the block.

3.1 Description of data output function

3 Data Output Function

3.1 Description of data output function

You must specify the useful data and its length (in bytes). The length is in the first data wordof the pointer.

The transmission job is initiated by means of the ST signal (start) and the interface isassigned.

After the transmission has been completed and the signal LBL (last frame) is not set, the userhas the option of specifying new data or another useful data DB. Retriggering is effected bysetting the signal ST (start). The user must retrigger within the number of PLC wait cyclesdefined in MD. Otherwise the CP interface is enabled.

If the signal LBL (last frame) is set before initial or retriggering, the job is finished after datatransmission and the CP interface is enabled.

Note:

The block supports data transfer up to a length of 4084 bytes.

The function block for data output executes a series of validity checks before assignment ofthe interface. If one of the requirements is not met, the interface is not assigned and the useris informed of the cause of the abort with the signals FEHL (error) and F-NR (error number). Atthe same time the job triggering is reset.

Assignment of the CP interface is not effected if:

• Not permissible user interface (UI No.),• NUTZ-DB/DX is not available or DB 0,• NUTZ-DB/DX too short,• Impermissible data block type (DB/DX).

The interface is enabled when the user interface has been parameterized and enabling hasbeen triggered.

The interface is enabled if:

• The signal LBL (last frame) is present and the transfer of the last frame has beenacknowledged positively.

• A negative acknowledgement has been issued after a frame transfer.• The signal LBL (last frame) is not present and the number of wait cycles has elapsed.

02.92 5 Configuration

5 Configuration

Data input/data output blocks

For problem-free use of the data input and data output blocks, you should adhere to thespecifications regarding the signal behaviour of the block parameters and to the guidelinesspecified on the next page.

5.1 Configuration notes for data input

For application and linking of the block in the user program for data input, you must considerthe following points.

• If the signal AFOR (continuation signal) is set, you can evaluate the data in the useful dataDB. You must indicate the end of evaluation by setting the signal ANST (initiation).

The signal ANST (initiation) must be set within a time less than or equal to the number ofPLC wait cycles. Otherwise, the CP interface is disabled by the PLC.

• If the CP is defined as a master and data transfer is effected unsorted, you must definethe sequence by means of the frame number yourself. Note that the frame sequence neednot necessarily be completed with the signal AEND (data input terminated); another twoframes which are part of this sequence might still be transferred.

• With the CP configuration software SINPS 315 you can define that frames be transferredwith end-of-text identifier. If these were not generated by the I/O unit, the data istransferred to the PLC after the character timeout with an error message. The user mustevaluate and respond to this himself.

• If the CP is configured as a slave, you must ensure that after the CP interface has beenenabled no further data is transferred. If this requirement is not met, the data is rejectedwhen the interface is assigned again (data loss!) and the job is aborted.

Reason: The CP interface is still active (XON and/or RTS/CTS); i.e. the CP receives datawhich, however, is not transferred to the PLC: However, the frame counter is stillincremented CP-internally. This leads to coordination problems in the PLC.

5.2 Configuration notes for data output

When linking the blocks in the user program for data output, note that the same CP interfacecan be assigned to several user interfaces via the parameter assignment of the addressingdata (DB 99 in the PLC as well as configuration software SINPS 315). Since the PLC has noaccess to CP-specific configuring data, no validity check fo double assignment is possible. Forthis reason the user must ensure that within a PLC cycle only one job is started via aparticular CP interface. The simplest way of interlocking is via the parameter ST (start).


5 Configuration 02.92

5.2 Configuration notes for data output

Also make sure that when the signal LBL (last frame) is set, the job is terminated and theinterface is enabled, otherwise, the block expects new parameter specifications for the sourcedata. An initiation for the same CP interface from another user interface is rejected, since thejob still running is not yet terminated.

If more than four jobs are triggered, no negative acknowledgement is issued but the jobs areprocessed after a job buffer has become free.

You must not change the addressing of the user interface dynamically using the DB 99 as longas an interface is assigned.

You must specify a posibive useful data length since no check is made. Block call(s) must beunconditional. Since the number of internal data buffers is sufficient, block calls in OB 1 (cyclicorganization block) are relatively time-non-critical. For special applications, calls are alsoconceivable in OB 10 (10 ms time alarm). The block cannot be processed in the process-interrupt organization block OB 2 to OB 9.

If the signal LBL (last frame) is not set, an interface remains constantly assigned. In order toprevent this, an interface is enabled after the PLC wait cycles have elapsed.

For data output, it is important to not that if the SINPS 315 CP configuration software is used,the parameter: Wait for XON: YES/NO is relevant. If ”Yes”is configured the remote I/O unitmust send XON; otherwise no data transfer is possible. The CP sends a negativeacknowledgement to the PLC (error 204), then the PLC terminates the job. If, despite this,data is output, the CP issues a negative acknowledgement (error number 204); then the PLCterminates the job.

5.3 Configuration notes for data input/output via the same CPinterface

The same CP interface cannot process inuput and output data in parallel. Every individual jobmust be terminated and the CP interface must be enabled before a data transfer in theopposite direction is possible. You must guarantee coordination yourself.

With data input it is possible to receive several frame sequences after assignment of the CPinterface. It must be ensured, however, that new frame sequences occur within the monitoringtime set in MD. This makes the time-consuming assigment/enabling of an interfacesuperfluous. The I/O unit may send any number of frame sequences. The CP interface isenabled with the negative edge of the signal ST (start). When the CP is operated in slavemode, then the PLC must send the internal command Data Start after a frame terminatingsequence; this command puts the transmission section in the ready-to-receive state (CP sendsXON and RTS/CTS). If the CP interface is subsequentyl enabled, the CP interface remainsactive. A following data output job is not executed and the PLC cannot issue an errormessage, since the CP does not send a respons to the PLC.

For data input/output mode via the same CP interface it is advisable to operate the CP inmaster mode.

The PLC machine data word ”PLC wait cycles” specifies how many PLC cycles the block willwait for further triggering after a transmission job has been completed.

If the MD is set to 0, no monitoring is performed.

This function prevents interfaces from being permanently assigned. The possible number ofdynamic jobs is thus reduced.

5.5 Signal charts for XON/XOFF-, RTS-LINE procedures and procedures in the trasparent mode

5.5 Signal charts for XON/XOFF-, RTS-LINE procedures andprocedures in the trasparent mode

5.5.1 General remarks

In this section, the functionality of XON/XOFF, RTS-LINE procedures and procedures in thetransparent mode is explained.

5.5.2 Communication control with XON/XOFF

The XON-XOFF line procedure is a character-oriented transmission method. The receivingsystem controls transmission of the output system by means of XON/XOFF. Data is generallytransmitted in half-duplex mode and in frames.

XON/XOFF is generally represented by the control characters DC1/DC3 (11H/13H); howeverboth control characters can be configured.

The DTR, DSR, RTS and CTS control and signalling lines need not be connected for theXON/XOFF procedure. The DSR signalling line is an exception. The evaluation of the DSR linedepends on the configuration. If the DSR evaluation parameter has been set to ”with”, theDSR status is scanned on transmission of each character.

5.5.2.1 Communication between ”intelligent” and ”non-intelligent”(unequal) nodes

The receiving station sends the XON character after switching on the unit or after initiation ofthe ”Data Start” command. This only happens if the configuring parameter first xon isconfigured accordingly (first xon = 1). If the parameter first xon = 0, no XON character issent at the beginning of reading in.

The receiving station sends XOFF if it is no longer ready to receive or if a frame has beenreceived completely. With a printer, this would be the case if the print buffer were full or theoff-line key pressed or if a fault had occured. The CP 315 sends an XOFF character if thereceiving scratch (input buffer for the respective procedure) is disabled, e.g. because ofequipment bottlenecks, or if previous jobs cannot be passed on due to missingacknowledgements.

5.5.2.2 Communication between ”intelligent” and ”intelligent” (equal)nodes

In the initial state, both stations are ready to send and ready to receive; no control charactersare transmitted. The procedure does not prevent an initiation conflict. This must be achieved inthe application. In addition to the control characters XON and XOFF, the STX character isrecognized as a control character. If a station receives an STX character during transmitting,the transmitter stops transmission, issues a negative acknowledgement for the transmitting joband waits for a receiving job. This receiving job must arrive within a specified timeout (linereservation time). If the timeout expires without a frame having been received, the station canprocess new transmission jobs.

DTR is set active on initialization

After initialization of the interface, the DTR control line is activated. After the command ”DataStart” has been issued, the procedure driver activates the RTS control line, transmits the XONcontrol character and enables the receiving scratch. A receiving scratch is available to thedriver when the interface is operated with ”with system 800 ID” or ”without system 800 ID”but ”with AS 512 protocol”. The user must keep to the useful data lengths specified in the AS 512 protocol and in the system 800 frame specification.




In the mode ”without system, 800 ID” and ”without AS 512 protocol” two receiving scratchesare available to the driver, which enable continuous data read in. The driver performsautomatic segmenting by entering the corresponding identifiers for initial, subsequent andterminating frame. These entries are effected by procedures of the device management. Theprocedures are called by the driver.

After the device management has passed on the receiving job, the receiving scratch isenabled again and the procedure driver sends the XON control character.

If the procedure driver receives an end-of-text (e.g. ETX) at the end of a frame, the receivingscratch is disabled and the job transmitted to the receiver. If the user has not configured anend-of-text, the job is transferred to the next communication level after the character timeout(end criterion) has elapsed. The procedure driver then transmits the control character XOFFdepending on the configuration and disables the receiving scratch. Whenever the receivingscratch is disabled, received characters are rejected

The ends-of-text for the input direction can be configured by the user who can decide whetherto assign no, one or two ends-of-text.

Data output: the pin designations refer to the transmitter in Fig. ”Minimum wiring required”.

After initialization of the interface, the DTR control line is activated.

After a transmitting job has been transferred to the transmitting scratch (output buffer of therespective procedure), the procedure driver is started. Depending on the configuration, theDSR status is checked before transmitting a character. A timeout for the first XON charactercan also be configured.





Data transmission is interrupted only after XOFF is transmitted by the receiver. The proceduredriver waits for the XON control character to be transmitted until the timeout Tu has elapsed.

If the monitoring time Tu elapses without an XON character having been received, thetransmitting job is returned to the transmitter with a negative acknowledgement.

The monitoring time Tu is necessary to enable the interface after a failure of the I/O unit.

5.5.2.4 The overlay procedure ETX/ACK

In addition to the XON/XOFF procedure, the ETX/ACK procedure can be overlaid. When usingthe ETX/ACK procedure, the receiving data is transferred in blocks by the transmitting station.Every block must be terminated with the control character ETX, i.e. the transmitting stationadds the control character ETX to the output data. The receiving station responds with thecontrol cahracter ACK, when it encounters the control character ETX when reading-out thereceive buffer. The transmitter is thus informed that the data block has been receivedcompletely

The overlay procedure ETX/ACK is frequently used for printers. With CP 315 the controlcharacter ETX can be configured. Further ends-of-text are, for example, EOT, M02, M30. Theprocedure rejects the control character ACK.

5.5.3 RTS-LINE (RTS/CTS)

The RTS-LINE line transmission procedure is a line-controlled transmission method, i.e. thecontrol characters XON and XOFF are not required. the functions of these control charactersare carried out by the RTS/CTS signal lines, which control transmission.

The RTS signal line is activated for reading in data only after the ”Data Start” command hasbeen received; in this way the transmitter is informed that it may start transmitting. If the bufferof the receiving station is full or a fault has occurred, RTS is deactivated.

Data output is controlled automatically by the SCC. If the receiver cannot receive all data, dataoutput is interrupted by disabling the CTS signal for the transmitter (RTS for the receiver). TheSCC transmission register is disabled automatically, i.e. the driver is not aware of the datatransmission interrupt. Depending on the configuration, the driver checks the status of theDSR line and evaluates it.

In addition to the signalling lines RTS/CTS, the modem control lines DTR and DSR can beconnected and evaluated. DTR is set or reset by the CP 315, DSR, on the other hand, isevaluated by the CP 315, if the signalling line is connected. As in the case of XON/XOFF,additional end identifiers can be configured for the RTS-LINE procedure driver. For normalapplications, however, these end identifiers are not required. During configuration theparameter ”end-of-text” must be preset to ”none”. If the procedure is configured ”without”end identifiers, elapse of the character timeout is used as an end criterion.

After initialization of the interface, the DTR control line is activated. The ”Data Start” commandenables the procedure driver to activate the RTS control line. The CP is ready to receive fromthis instant, i.e. the scratch is enabled.





As soon as the receiving scratch is full, the driver deactivates the RTS. The output systemmust then stop transmitting. After clearing and/or after enabling the receiving scratch. RTS isagain activated and data read-in can be continued. The driver operates in the mode ”withoutsystem 800 ID” and ”without AS 512 protocol” with two receiving scratches (please refer toXON/XOFF).

The period for which RTS is inactive is monitored, this ensures that a failure of an outputdevice is recognized. This timeout corresponds to the time Tu of XON/XOFF (please refer toSection 5.5.2.3).

After initialization of the interface, the DTR signal line is activated.

The signal level of DSR is checked prior to transmission of a character (if so configured). Aftera character has been transmitted into the transmitting buffer, the timeout Tu is started, in casethe receiving station does not activate the CTS line.

5.5.4 Communication control in the transparent mode

During data transmission in the transparent mode, the data are transmitted without controlcharacters.

Communication control as for procedures XON/XOFF and RTS-LINE is not possible here. Purenet data are transmitted.

The RTS control line continues to be controlled. The transparent mode offers the user theoption of using his own control characters in data transmission and of defining his ownprocedure. The frames are segmented by the driver since it operates with two receivingscratches. The end criterion for the driver is elapse of the character timeout or the configuredend identifier.

2 Description of the Function

The user must load blocks FX 68 to FX 72, and also FX 27; furthermore he must call block FX 68 in OB 1 with an unconditional call. The function block monitors the logging function and checks the syntax of the part program ”Framework for log”. The user must monitor thesignal FEHL and initiate responses, if necessary (see the Section ”Error Messages”).

Data output configuration

The lists mentioned above can be created with the configuration software SINPS 315. Theformat list is not required for data output on the printer. The input, output and address list arenot relevant. They must, however, be created formally, i.e. every list must be completed forthe configuration to be correctly executed (see example).

The interface list is important for the printer output and must be created exactly.

1.1 General remarks

1 Introduction

1.1 General remarks

With package 8 it is possible to call the current date and time-of-day of a data block.

Precondition for this is a clock generator on the multiport or on the dualport RAM.


02.92 2 Date/Time-of-Day Function

2.1 Description of the date/time-of-day function

2 Date/Time-of-Day Function

2.1 Description of the date/time-of-day function

The date/time-of-day function is implemented using the FX 28.

A clock generator in the multiport or dualport RAM provides the clock. The time-of-day andthe date can be entered on the operating panel. These values are stored and updated in thedata block DX 33.

2.2 Description of the FX 28

The function block FX 28 DAT-UHR implements the following program parts:

• Setting the date and the time-of-day with a flashing modification line on the screen.

• Accepting the modified values and setting the clock. The date/time-of-day line is markedwhite on the screen.

• Three states are essential for updating the time in DX 33.

– With an active display, the date and time-of-day are updated every 10 cycles in DX 33by means of a counter.

– With an inactive display and active logging again the DX 33 is written every 10 cycles.

– With an inactive display and inactive logging, the DX 33 is updated every 200 cycles.

• If the day of the week is to be updated as well, it must be entered in DX 33, DW 10,before CHANGE/ACCEPT (1...7, Mo...Su).
