21 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 alternative 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. Maschinenfabrik Reinhausen /00 EN TAPCON

23 4 Data points Input Unit Scale Designation Range value Request function 69 The command is available if parameter voltage level delta in the TAPCON 260 is zero and the position of the inputs for remote control of voltage level 2/3 is off. 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 control on off: parallel control off 74 off: parallel control on on: parallel control 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 Parallel control mode master on: parallel control mode master on off: automatic selection of parallel control mode master/follower on Maschinenfabrik Reinhausen /00 EN TAPCON

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 control mode follower on off: parallel control mode follower off 81 off: parallel control mode follower on on: parallel control mode follower off Parallel control mode follower cannot be set if the TAPCON 260 is set to parallel control mode circulating current.
