Hello,
thank you for your respond.This will help me a lot.
My other thing is, that my client wants from me to have the possibility to change offline, without connecting to PLC, the MB pointer to I/Os.
So basicaly, if he is changing the wiring, he enters in one of the HMI screen and puts the new input/output to the MB.
I dont know if you understand?
Thank you,
Boros Csaba
