Hi, I am programming a large motion and PLC system using Siemens Step 7 and an S7 300 CPU. Have been trying to figure out a good way to create alarms that tells me a specific remote I/O rack has failed. I have installed OB86 in my processor, but am having a difficult time trying to figure out how to display an alarm on my WinCC station that tells that a specific rack number has failed. I am only asking how to set bits that tell me that the rack is faulted, adding the alarm itself is easy. The Siemens documentation is so obtuse about everything and you have to pour through approx 5325 pages before you find any meaningful information. Havent been able to find any example code I can use as a model.
Want to build this up to the point were the OB's are actully functional, and I think once I get this first one going then I can build on that.
Thanks!
Debbie
