C-More EA9 HMI Series Panel to PLC and PLC to Panel Settings

We will now look at the C-More panel settings for communication to the PLC. The C-More EA9 HMI (Human Machine Interface) Series Panel will communicate to the PLC directly through the tag database that we discovered in our first program. We were able to read and write individual bits in the PLC.
Panel to PLC communications is used to write information into the PLC; like current screen number, displayed, good communications, pop-up keyboard, and current language number used in the HMI.
PLC to Panel communications is used by the PLC to control the HMI. Switch to screen
number, beep, increment and decrement the Clock by one hour, clear alarm history, clear
alarm count, start screen saver and select language are the items you can control in the
HMI.
PLC Error is used to communicate internally in the HMI the PLC error state and PLC error
code value. We will be setting up and testing our PLC to Panel and Panel to PLC
communications on our EA9 C-More. Let’s get started.
