Hi again.
I have a question about wanderware. Althought, I am not working directly with it.
I am making some modifications in an AB SCL5 routine, and a working partner is making the changes in the wonderware.
What is happening, and the plant operator said it also happens in the plant, is that, for any reason, the wonderware is turned off, or the pc shut down, it sends 0 to every variable that have a connection with the PLC.
That is to say, i am in the middle of a run with the oven (it is an oven control) and if they turn off the pc with the wonderware.... pufff. i dont have any more data in the PLC. cero. nada. no mor CV, timers, security values...
So..., the question. is there some way of avoiding this nasty and unsecure way of operation?
thanks.
