4 Protocol specification


Protocol specification

The IEC60870-5-103 interface protocol was originally developed for commu-nicating between protective devices. The pre-defined function types and theassociated information numbers are not suitable for the information that thevoltage regulator has to transmit.

A function type from the "private sphere" of the protocol is therefore used forall "non-generic data points".

The information numbers for all general commands and messages with thefunction type from the "private sphere" are specific.

Analog values are transferred in the control direction (command) and moni-toring direction (message) using a generic message type. All measured val-ues are assigned to class 2 and all parameters to class 1.

In addition to the 9.6 and 19.2 kilobaud rates required by the standard, 38.4and 57.6 kilobaud can also be selected on the voltage regulator.

Message structure

The function types, type codes and data types listed in the data tables areexplained in the following section.

The following function types are used:

110 = function type from the private sphere (can be defined specifically)

254 = generic function type

255 = global function type

The following type codes are used:

1 = message with time stamp

6 = time synchronization

7 = general query

10 = generic data

20 = general command

21 = generic command

The following data types are used:

7 = short real

Sequences

Sample sequences of the protocol are described in the following section.

Time synchronization

Table 4: Sample command for time synchronization

After time synchronization, the voltage regulator returns the time synchroni-zation feedback as positive confirmation. The reason for transmission is setto 8.

This time specification is used, among other things, for the display inTAPCONtrol visualization software.

The time stamp in the regulator's telegrams is produced by the communica-

tion card and is only set when the message is sent.

The examples were taken from various log files where the message trafficbetween a computer and the voltage regulator was recorded. The address ofthe voltage regulator was set to 1.

Some of the tap positions in the sample telegrams selected are different inorder to show examples with different values. The same tap position is nor-mally reported in all three telegrams.
