Communication with PM554 and 2 CP405 via 2 to 1 connection
I'm having a problem with reading values in the second HMI I'm sending an image of the connections that i have made and the software if someone could help me to make the second HMI read the addresses of the variables from the PLC, at the moment the 2 panels are communicating, the first one that is connected directly to the PLC is working fine, but the second one is not reading the values from the variables of the PLC and it's not working properly
thanks in advance for the help
You are trying to make MutliLink Communication between PLC / Master HMI / Slace HMI.
At this configuration:
- You have to communicate Master HMI and Master PLC via RS232 or RS485.
- You have to communicate Master HMI and Slave HMI via RS485.
For more details you can use CP400 Soft Manual. You can find that manual here:
Hope it helps you.
