Hi All,
I have 2 Compactlogix PLCs(CP1 and CP2) controlling 2 different areas of the Plant and I also have 2 Panel view HMIs mounted on the each of the PLC control panel door.
These HMIs and PLCs are connected on Ethernet network. These HMIs use tags from both the PLCs to diplay and control the Plant. when I use to create or amend the HMI screens, using tags from the both the PLCs was no problem on HMI programming but now I have to program one the PLC to do some control task and I have to use one of the sensor connected to CP2 in CP1 program.
There are 2 things to ask
1. Can anybody please tell me how use CP2 tag in CP1 program ?
2. I want to stop any equipment which was left running in Automode at 12am midnight as safety thing. How do I monitor the PLC clock and put this safety instruction in the program with a reset option or override option in the case if someone wants to run the plant even after 12am.
The programming language is RSlogix 5K.
Thanks for the HELP in Advance.
