Hey there,
Just wondering if any of you may have experience with the ET200s bus in Siemens?
Basically what I want is a bool or value to tell me that the bus is online and running. The reason for this is I have a 1Count5 on the bus and want to turn off the SW_Gate when the bus is offline so I don't return the current count to 0 - then when its back online I load the last value to the counter and enable the SW_Gate again.
I have set up OB100 to load the value to the counter after PLC power up, but the ET200 is powered externally in another machine.
Any thoughts?
Cheers...
