4 Data points


4.2 Control direction

The current software version only accepts the control function codes ‘direct operate no ack’ and ‘direct operate with ack’ for the commands. Only one command object is allowed in one message.

The answer after a ‘direct operate with ack’ is a copy of the command object.

To be sure that the command really has been executed you have to look if the status of the corresponding binary input changes after the command.

The code field in the control code object can be pulse on/off and latch on/off.

Every command can be given on two adresses (object numbers). The alterna-tive number has an offset of 64. Commands with the alternative number are inverted before they are given to the voltage regulator. Therefore it is possible to switch to manual with an off command with object number 0 or with an on command with object number 64.

The remote mode must be set for commands from the control system on TAPCON® 260 to be executed on the Voltage regulator .

4 Data points


4.2.1 Single bit commands: object 12, variation 01

Input Unit Scale Designation Range value Request function

0 N/A N/A Auto/manual off:manual on:automatic

64 on:manual off:automatic

1 N/A N/A Raise on:pulse to tap changer to raise voltage

65 off: pulse to tap changer to raise voltage

2 N/A N/A Lower on:pulse to tap changer to lower voltage

66 Off: pulse to tap changer to lower voltage

3 Set voltage level 1 on:set voltage level 1

67 The command is available if parameter ‘voltage level delta’in the TAPCON® 260 is zero and the position of the inputs for remote con-trol of voltage level 2/3 is off.




4 Data points




6 SI command 1 on: set flag off: reset flag

70 off: set flag on: reset flag

7 SI command 2 on: set flag off: reset flag

71 off: set flag on: reset flag

Each of the three ‘SI commands’ sets a corresponding flag in the TAPCON® 260. The status of the flags can be used like an input of the IO or UC module to activate or deactivate a function of the TAPCON® 260. Example: If parameter ‘Input parallel group 1’ is set to ‘SI:cmd1’ for two TAPCONs then parallel control of these TAPCONs can be switched on/off by setting ‘SI command 1’ on/off for both TAPCONs.

10 Parallel control on/off on: parallel con-trol on off: parallel con-trol off

74 off: parallel con-trol on on: parallel con-trol off

Parallel control on/off can be written only with some versions of the TAPCON® 260 software. Normally, parallel control on/off is only an indication of the current status of the TAP-CON® 260.

22 Parallel control mode master

4 Data points



80 off: parallel con-trol mode master on on: automatic selection of pa-rallel control mode mas-ter/follower on

Parallel control mode master cannot be set if the TAPCON® 260 is set to parallel con-trol mode ‘circulating current’. Switching from parallel control mode master to automatic selection of parallel control mode master/follower is also not possible if the TAPCON® 260 is set to parallel control mode ‘circulating current’.

23 Parallel control mode follower

on: parallel con-trol mode follow-er on off: parallel con-trol mode follow-er off

81 off: parallel con-trol mode follow-er on on: parallel con-trol mode follow-er off

Parallel control mode follower cannot be set if the TAPCON® 260 is set to parallel con-trol mode ‘circulating current’.

5.1 Unsolicited messages

If unsolicited messages are enabled the status of the binary inputs will be sent if one of them has changed. The analog inputs will be sent if the tap position has changed.

The current protocol software can only enable/disable all unsolicited messag-es together. If a message with function code enable/disable unsolicited mes-sages is detected the complete mechanism will be enabled or disabled.
