(*) The parameter Include in scan is treated as a bit map. The first (lowest) bit is forscan group 0, the highest (leftmost) bit is for scan group 15. A 1 at position x will includethe Polling-, SOE- or Terminal Status Word in the scan response for this group.

Example: 1 : Include appropriate word in scan response group 02 : Include appropriate word in scan response group 1

3 : Include appropriate word in scan responses group 1 and 2

Note:Because of the structure of this protocol implementation, there are no input buffernecessary for the Conitel 300 host interface. That is why the following line parameter arenot used:

Buffer Size for Prio 1 Data Points

Buffer Size for Prio 2 Data Points

Buffer Size for Integrated Total (ITI)

Priority of ITI queue

Buffer Size for spontaneous transmitted AMIs

2.3 Polling Words

2.3.1 Conitel Polling Word

The Conitel polling word will be returned in any scan group in response to a scanrequest, if this feature is enabled (See Table 2-1) . The following status bits are supportedby RTU560:

Bit 1 = 1: Change of data has occurred in scan group 1


.. ..


Bit 11 Set to 0

Bit 12 = 1: Analog change in the current scan group

2.3.2 SOE Poll ing Word

The SOE polling word will be returned in any scan group in response to a scan request, ifthis feature is enabled (See Table 2-1) . The following status bits are supported by theRTU560:

Bit 1 = 1: At least one event has been stored in the SOE buffer

Bit 2 = 1: SOE buffer overflow

Bit 3 Set to 0

Bit 4 Set to 0

Bit 5 = 1: RTU not synchronized

Bit 6 = 1: Only 50% of the SOE buffer remaining

2.3.3 Terminal Status Word

The terminal status word will be returned in any scan group in response to a scanrequest, if this feature is enabled (See Table 2-1) . All Bits in the terminal status word areset to 0.

2.4 C300 Error Response

Error messages from the RTU560 are reported with Function Code 6 (Error responsefrom r emote) . The error code is returned in Section B of the message. RTU560 supportserror codes according to Table 2-4.

ErrorCode

Meaning Description

0x00 Illegal function orfunction not supported

Is set if the RTU560 receives a function code, which isnot included in Table 2-2.

0x02 Output group notdefined

Is set if RTU560 receives a Function Code D(Raise/Lower) or 3/5 (Setpoint A/B) with a group no. notdefined within the RTUs database

0x03 Illegal execute Previous message was not a trip/close0x04 Bad 1 of 12 modifier

codeOnly one trip/close can be issued per command

0x0E Retransmit messagewas first message

Is set if RTU560 receives a Function Code B (Retransmit last message sent) as first request of dataafter restart

0x28 Output not executed Output is already active0x29 Check-before-execute

process error

Is set if RTU560 receives a Function Code 2 (Trip) or 4

(Close) with a group no. not defined within the RTUsdatabase0x2A Execute process error Is set if RTU560 receives a Function Code 1 (Execute)

with a group no. not defined within the RTUs database0x31 Invalid time of day

0x32 No SOE eventspresent when scanned

Is set if RTU560 receives a Function Code A (Sequenceof Events) and the SOE buffer is empty.

Table 2-4: Conit el 300 Error Codes

2.5 Redundant Communication Lines

It is possible to configure a redundant communication line. Both lines must be on thesame CMU board. It is the task of the Control System (CS) to switch between the lines.The RTU560 will answer each scan request from both lines.

The RTU560 will store the last sequence of events, transmitted to a Host, until a newscan request is received on the same host line. This last sequence will be retransmittedon the redundant line after a Function Code A request (if still available).

6 Time Synchronization

6.1 Principle

The RTU560 supports different methods of time synchronization. The timesynchronization can be done via

Radio Clock (GPS, DCF77, ) Clock synchronization command from a control system (s) sntp ( S imple Network Time P rotocol) External Minute Impulse

Parameter: Time synchronization mode (RTU560-Parameter)Host Line (Line Parameter)

6.2 Time Update

The Time Update Message is sent periodically by the Conitel 300 master station using. The in the message is ignored. Ifthe time received is syntactically incorrect, the RTU560 generates an error message.

Because of missing information in the time update message, the Year is initially set to1980 after restart of the RTU560. If RTU560 was already synchronized, the year will notbe updated in current system time.

Note: In order to enable Sequence of Events (SOE), it is necessary to synchronize theRTU560 at least once.

6.3 Time Correction Factor

In order to calculate the communication line delay the Time Correction Factor is used.The field in the message is ignored.

Note: The second block in the reply of RTU560 is cleared.

7 System Events

The host interface manages internal status messages of the RTU560. These statusmessages can be created from the host itself or other activities of the RTU560. Thesystem events of other activities are send via internal communication and are processedby the HCI.

The system events of a RTU are send as DI messages through the Conitel 300 protocol.Therefore a own information group is needed.

The following tables shows how the system events are send to a host.

Descripti on of system event Index At least one indication faulty 16 At least one analog value faulty 17 At least one digital value faulty 18 At least one pulse counter faulty 19 At least one command is faulty 20 At least one setpoint is faulty 21 At least one digital output is faulty 22RTU is faulty 23RTU is active 24RTU is synchronized 25External clock is inoperable 26Local printer is offline 27

System battery low (RTU560E only) 29 AC power supply faulty (RTU560E only) 30 At least one PLC function is not running 46 At least one PLC function cycle time exceeded 47RTU inoperable 48Power supply failure in central subrack (560CSR01) 59RTU A is active 60RTU B is active 61RTU A is operable 62RTU B is operable 63Command supervision x circuit disconnected or faulty, 1 x 32 64 95Local control authority active (Integrated HMI) 100Host x is Online (1 x 8) 101 108Host x: At least one process data change lost due to queue overflow 117 124 (*)Host x: At least one counter value lost due to queue overflow 133 140 (*)Database identity tag 174

Note: The System Events 117 to 124 and 133 to 140 are not supported by the HostCommunication Interface with Conitel 300 Protocol.

8 Functional Controls

8.1 Data Requests

Functi on Code 0 (Scan Data)

The scan reply returns the data in the following order:- Conitel Polling Word, if included (Configurable)- SOE Polling Word, if included (Configurable)- Terminal Status Word, if included (Configurable)- Scan Data

Note: If any polling word is included, first allowed index is number of pollingwords+1. Gaps within indexes should not be configured.

Functi on Code A (Read new SOE events)

Note: RTU must be synchronized in order to store SOEs

Function Code B (Retransmit last message sent)

8.2 Counter Freeze / Reset

Functi on Code E (Counter Freeze)

The reply returns all ITIs of the requested Station/Group with their current values.

Functi on Code F (Counter Freeze and Reset)

The reply returns all ITIs of the requested Station/Group with their current values andclears the values afterwards.

Function Code E/F with broadcast address 0:If the command is sent to all stations, the remote station returns no data to themaster station. The accumulator data may be read by issuing a scan request to theappropriate station and group addresses.

Note for local I/O: Because the Counter Reset Function is implemented in the Conitel300 Host Communication Interface, the End of Period Wrap Around function mustbe enabled

Parameter: End of Period Wrap Around (PDV-Parameter ITI)
