Hello,
a bit of a special question: my last installation will be copied and connected to a simulator for accident training purposes (I don't go into detail here). Since a trainingsession can take a few hours those sessions are mostly broken into 2 parts with a break (everyone needs there coffee or thee on time of course). The simulator can be putted on hold and in this case every calculation stops so that when the break is over it can be putted into run to go further where left. This signal can be picked up but the question is: can a PLC process be putted on hold with for ex. an Dv?
The window object under each PlcPgm has the attribute ScanOff to turn off the execution of this PlcPgm. You could make some plc code to set and reset this in all plcpgm from a dv.
You can also control ScanOff with the xtt commands 'plcscan /off /all' and 'plcscan /on /all'.
Another alternative is to configure the simulate server from which the execution of threads and PlcPgms can be controlled.
