Good Afternoon All,
I am hoping someone here will have some input to get me past this terrible hump. I have programmed Siemens 200 and now 1200 for years. Had a customer require AB as it was all they have at their facility. And thus my nightmare started.
I have gotten quite a bit of my programming working, but I am utterly stuck at one point. I am trying to use latched and momentary buttons in the PVP to change the state of bits in the PLC. Unfortunately, I cannot get any of these buttons to work.
I know i have comms as I am able to read and write integers back and forth. I just cannot change bits.
I am sure it is a total newbie error, but I am at my witts end and rockwell wont help as project delays pushed commissioning out of the warranty period.
Thanks in advance.
Andrew
