I am trying to communicate with the cfp1804 via modbus and am not receiving a response from the unit. I am able to establish a connection, but cannot receive any response from the slave. I am communicating via python and the socket library. does the message to the cfp need to be any particular data type? any help with this would be much appreciated as i am new to modbus and am not entirely sure i have used the addressing correctly. is the unit defaulted to slave id 1 and does anything need to be done to the cfp to configure it to accept modubus tcp commands?

Hey Sofo2,
There is a KnowledgeBase Article online that should be of help to you!
here Can I Find the Documentation for using Modbus with the cFP-180x?
