cfp 180x modbus

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?
