I'm using a Nano-10 as the brains in a microwave generator. A fairly simple design with three digital inputs (2 thermal switches and "mag energize" from the main System PLC) and one analog input (transformer current). Digital outputs consist of 1 output to energize the transformer and another output to send feedback to the System PLC. Jumpers J1 and J4 are OPEN.
So, I'm looking at On-Line Monitoring to monitor the Analog Input (transformer current) and this weird message pops up... "PLC paused by DIP SW #4 Turn OFF DIP Switch #4 to release it"
According the documentation, DIP #4 is the same as J4 on the Nano-10. And, it should be OPEN for NORMAL RUN mode. Which it is.
Also, the PLC is still running. It's NOT paused. I can monitor the Analog Input and see it changing values. I can turn the microwave ON and OFF. I get feedback to the System PLC. But, the message remains. Oh yeah, it only pops up when On-Line Monitoring is active.
The message is not currently a problem. It's just weird. I've never seen this before. But, this is only the second generator of this design I have built. I'm building a third unit and I'll let you know if the same message pops up. Meanwhile, if anybody has any ideas about this weird message, I'm all ears.
