Good afternoon! We're having a problem with a modicon 984-380 CPU, burned communication ports.
We installed a modcion 984-680 CPU in place and are communicating via modbus plus using an ADAM converter (Ethernet-Modbus plus).
We were able to communicate, but when trying to download the program, it pops up the error "Modbus error code 237".
We have already configured in offline backup the new CPU and its features, but we were not able to download.
Please could someone help us?
Thank you.
