Hi Mr. Griffin,
I'm in a real emergency condition in which I can't get connected with my OP7. I get the alarm: "PLC not present" I have read all articles about using fb51 and ob21, 22, DB51. But I don't have FB51. Even I load the PLC functions, but it only has 240 to 252. How do I can find or how can I program it. Why every one don't explain it full. Is it a legacy??? Please help me!
I want to monitor some analog values and order some bits and analogs to PLC. I have written the PLC program and OP program and just remains interface.
