1 General notes 1 General notes 1.1 About this document This document describes implementation of the interface protocol IEC60870-5-103 for the TAPCON 240. Read this description along with the technical file for the TAPCON 240. 1.2 Information about the standard The <Communication protocol> interface protocol was originally developed for communication between protective devices. The pre-defined function types and associated information numbers are not suitable for the information that the voltage regulator has to transfer. A function type from the "private sphere" of the protocol is therefore used for all "non-generic data points". The information numbers for all general commands and messages with the function type from the "private sphere" are specific. Analog values are transferred in the control direction (command) and monitoring direction (message) using a generic message type. All measured values 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, baud rates of 38.4 and 57.6 kilobauds can also be selected on the voltage regulator.

Byte 1 Class Description 20 110 16 1 Auto/manual (On = auto mode; Off = manual mode) 20 110 17 1 Raise (On = raise; Off = lower; only in manual mode) 20 110 18 1 Lower (On = lower, Off = no function; only during manual mode) 20 110 19 1 Raise/lower desired voltage value This function is optional. Parameterization is undertaken by MR. The desired voltage value function 1/2/3 is possible under the following conditions: - no inputs parameterized for selecting desired voltage values 2 and 3 - raise/lower desired voltage value function not parameterized Parameterization is undertaken by MR. 20 110 19 1 Desired voltage value 1 20 110 20 1 Desired voltage value 2 20 110 21 1 Desired voltage value 3 Each SI command sets a flag in the TAPCON 240. The status of the flags can be used like an input for the I/O or UC modules to activate or deactivate a TAPCON 240 function. Example: If the "Parallel group input" parameter is set to "SI:cmd1" for two TAPCON 240, parallel control for these TAPCON 240 can be activated or deactivated by setting the "SI command 1" on/off command for both TAPCON 240. 20 110 27 1 SI command 1 20 110 28 1 SI command 2 20 110 29 1 SI command 3 20 110 35 1 Parallel operation (On = activate circulating reactive current parallel operation, Off = deactivate parallel operation) 20 110 36 1 Master parallel operation method (On = activate master parallel operation mode, Off = activate "Automatic synchronization" parallel operation mode) 20 110 37 1 Follower parallel operation method (On = activate follower parallel operation mode) Table 10 General data in control direction The voltage regulator returns the command received with reason for transmission 20 if the message has been accepted. 16 TAPCON 240 2398402/00 EN Maschinenfabrik Reinhausen 2010

The reason for transmission is set to 8. These time details are only used for display purposes in the TAPCON trol visualization software; internally the regulator uses a continuous RTC. The time stamp in the regulator's telegrams is produced by the communication card and is only set when the telegram is sent. Maschinenfabrik Reinhausen 2010 2398402/00 EN TAPCON 240 19

The voltage regulator address was set to 1. Some of the tap positions in the sample telegrams selected are different in order to show examples with different values.

6 Tap position telegram 6.3 Setting time and date settings The TAPCON 240 has a counter module which counts the number of seconds after the supply voltage fails. Its supply is buffered by a large capacitor such that it continues to count for at least a few days even if the TAP- CON 240 is switched off. The time and date are set using an offset value which is converted into the time and date displayed in the measured value plotter screen along with the current counter reading. The interface software sends the time and date from the IEC103 time synchronization telegram to the actual CPU with the regulator firmware. The regulator firmware uses this information to calculate the new offset value to display for time and date in the measured value plotter screen. The counter in the TAPCON 240 counts whole seconds. Because the figures are rounded up or down, the time displayed in the measured value plotter screen may deviate from the time in the time synchronization telegram. The TAPCON 240's time and date will only be set from the control system's time synchronization telegram if both the interface software and firmware in the regulator support this. The telegrams' time stamp at the interface is not affected by the setting for the time displayed by the TAPCON 240. This time stamp is produced locally on the CIC card itself. 28 TAPCON 240 2398402/00 EN Maschinenfabrik Reinhausen 2010
