Function blocks are depicted as rectangular boxes inthe control logic diagrams. Input signals are brought infrom the left, output signals exit to the right. In the EDScontrol logic diagram, only the connections actuallyused appear, and sometimes special connections forEDS controlEach function block is identified by a name stated atthe top of the box concerned, e.g. "AND" for an ANDoperation.

A function block’s mode of operation can berepresented by a (standardized) symbol only in thecase of simple basic functions like the AND element onthe left which is depicted by "&". The inputs and outputsare then not designated at all or with "En" / "An".

In the case of complex function blocks like a binarydrive control (an excerpt is illustrated on the left), theinputs and outputs are designated by mnemonicabbreviations, and thus explained, e.g. „FE“ means„Enable On“). The precise mode of operation isspecified in the detailed function block descriptions.

Various signals are encountered at inputs and outputs:

Binary signals:Only 2 possible values: "1" and "0"correspond to "satisfied" and "not satisfied",

i.e. the effect stated at an output will be achieved with"1". For example, at input FE the enable for ON issatisfied if it has the value 1. This is the case when atthe state at this input is satisfied, i.e. "Level > LOW".

If the specified state is not satisfied, its signal has "0",and the "effect" (here the enable) is not achieved.If a binary signal is disturbed, it is set to "0". Thisprevents a disturbance triggering an unwanted effect.

Sometimes signals have to be inverted. This isindicated by a small circle at the input of a functionblock. For improved comprehension, a "NOT" can beinserted in the text before the state concerned.In the example shown on the left, the AND is satisfied if- the pump is ON and- the flow rate is NOT > MIN.Inversion is performed only at inputs and in the functionin which the value for inversion is formed ("source").

In the case of process messages like ON and OFF,OPEN/CLOSE, >/<, you must always remember that ,for example, the opposite value of OFF is not ON, but"NOT OFF", to ensure that a "0" value caused by adisturbance does not simulate the "ON" state. In thecontrol logic diagram, it is always the active signalwhich is used. Only for messages in POS and PMS is,for example, >/< used for value 1/0. Exception: e.g.OPEN/NOT OPEN in the case of actuators.Standard telegrams ("Signal bundle")

There are whole groups of binary signals which havethe same origin or the same destination, , e.g.:- the "checkback messages" of a binary control

functionin the case of ON/OFF, PROTECTIVE commandsand disturbances,

- key commands from the POS (or from the desk)with ON, OFF, STOP and ENABLE keys.

A signal group of this kind (signal bundle) is called a"standard telegram", since it is transmitted n atelegram, and the arrangement in the telegram isstandardized. A standard telegram is depicted as aninput or output like a single signal.The precise composition of a function block’s standardtelegrams is shown in the precise function blockdescription.

An analog signal may occur as a link between modules/ function blocks as a fixed specification. At the bus, ananalog signal is transmitted in a telegram in digital form(as a combination from 12 x 1 or 0 = 12 "bits"). Thismeans that the resolution (smallest difference between2 values) is 0.048% As a fixed value specification: 0.1%, as a parameter: 0.05.An analog signal is depicted as an input or an output.In the transducer, a current range (e.g. 4 - 20 mA) isassigned to the physical measuring range (e.g. 0 to 3bar); the input module converts into the bus telegram,with which -200 % to +200 % of the measuring rangeconcerned can be transmitted (in the example : -6 to +6bar).A range from -800 % to +800 % is available inside aprocessing module.

An "integer value" is a whole number, e.g. a stepnumber. An integer value is transmitted in a telegramwith 14 x 1 or 0 (14 bit), and is depicted as an output.Resolution (smallest difference between two values) is1, even as a fixed-value specification.

A "factor" is a dimensionless number (e.g. 1.5), bywhich an analog value (e.g. 42 %) is multiplied.Factors are coded with a "k" in function blocks.A factor may lie between -64 and +64;the resolution (smallest possible difference betweentwo values) is 0.03 (or 0.015 if it is specified as aparameter).

A time value is a time specification in seconds forbinary time elements (e.g. switch-on delay) and analogtime-dependent functions (e.g. correction time for a PIcontroller).Range and resolution are:0 .. 40,95 s at 0,01s ("short-time element"), or0 .. 4095s at 1s (normal use)

Monitoring and selection MVNfunction, analog

This function block can be used to generate a reliableanalog value from several analog signals (e.g. severalmeasurements), e.g. for an analog control.

- Variable number of inputs (max. 5).- Monitoring of inputs E01 - E0n for

- disturbance bit set and- impermissibly high differential to the other inputs.

A = undisturbed inputs

Number of undisturbed inputs

∑

This is computed with an iterative procedure:

a) Output = mean value of the undisturbed inputs

b) Sorting out the input with the largest differentialfrom the mean value only if this differential isgreater than DIF; it is then regarded asdisturbed.Otherwise: finished.

c) If number of the inputs still undisturbed is <M or1: finished, otherwise to a).

Annunciation outputs MS and MG:

MS = 1, if at least one input has been detected asdisturbed.

MG = 1, if fewer than M inputs have been detected asundisturbed.

If there are (now) only two undisturbed inputs (without adisturbance bit) available, but these are more than DIF(%) apart, the mean value of the two inputs isnevertheless output, and this error indicated by a 1 atMG.

If none of the binary inputs B00 to B14 is assigned, astandard telegram (signal bundle) that is being receivedat Input WRT ("Word") will appear unaltered at theoutput.

If one of the binary inputs is assigned, its value will bewritten into the output telegram, independently of thecorresponding bit of the input telegram. In this way anexisting standard telegram can be altered.

If no standard telegram is connected at Input WRT, astandard telegram will appear at the output only withthe values of the binary inputs. In this way a standardtelegram can be generated.

Non-assigned inputs are interpreted as "0".

The binary inputs can be fixed specifications or outputvalues from other functions.

Output(A) (stored binary signal)

In the symbol, the inputs are named"S" for "set" and"R" for "reset",

Therefore this is a single ON/OFF memory (RS-FLIP-FLOP).The "1" behind the letters, e.g. here "R1", shows whichinput is "dominant", i.e. determines the output valuewhen there is a "1" at both inputs.(Here this is also the state at switch-on. This could be stated with "I=1", for example.)

RS flip-flop ("memory") RSR

The output assumes the value 1 when at S a signalwith the value 1 is being received and R1 has the value0.The output retains the value 1, even when S is 0 again.With the value 1 at R1, the output is reset to 0.

If R1 and S have the value 1, the output has the value0 (R is "dominant").At power-up (when the module is plugged in), theoutput is 0.

The reset input isdominant.

The limit values are stored in a limit value list, as withanalog input modules. The following particulars can bespecified for each limit value:- limit value in %, range: 0 .. 110%, resolution 0,1%- whether "upper" or "lower" limit value (determines position of hysteresis),- hysteresis (HY1 to HY4 for 0.39/1,56/3,12/6,25 %)The input value is available unaltered at Output A. Adisturbance bit in the input signal is output at Output A,and also sent onto the bus by control modules (when Ais connected to an output).

If there is a disturbance bit in the input signal, all limitsignal outputs will be set to 0 (Gn & GNn).A "1" at SSB suppresses the disturbance bit at AG,A "1" at SSR suppresses the set-to-0 (at AG).A "1" at SG1 to SG4 switches both limit signals (Gnand GNn) of the limit value concerned to 0.

Pulse counter ZIP

This function block is used on the multi-purpose inputmodule 81EU01 in the "pulse counter" operating mode.It counts the pulses at Input E (positive edges frominput channel) and puts them out as 5 connectedtelegrams for 8 BCD-coded decades (Data Type 4).The counting frequency is max. 25 Hz with a bounce-free input signal, otherwise max. 10 Hz.Counting is performed only when there is an enable atInput FR with "1" (without connection: satisfied).A "1" at Input RS (reset) sets the counter to the valuespecified at Input STW (starting value) (withoutspecification to RS: 0)The counter reading is transmitted per event if it altersby more than the value specified at Input ZS (countthreshold), or if it is reset per RS, or the count range isexceeded. A fixed time-out of 200 ms applies here.At the DZ input (difference formation cycle), a timebetween 1 and 10 minutes can be specified, in whichthe change in the counter reading is determined. Thisdifference is transmitted per event over the AD output,together with the ongoing value.

Up to four (x 2) limit signals can be formed from theinput signal. The limit values are specified with InputsGW1 to GW4, and stored in a Limit Value List.The limit signals are transmitted at Output AG as DataType 3 (see GRE or GSG). To represent their use, theyare depicted as single signals.
