As we understand, the connection should be like this: PC <-- TCP/IP --> CSE-H21 <-- Serial --> PLC. To find out whether the problem happens in TCP/IP connection or in Serial connection, we would like to ask for more information. First, please make sure the serial configuration is set properly between the PLC and CSE-H21 device. There will be a TCP/IP connection between CSE-H21 and your PC. We guess that your working scheme is similar to the one in the attached photo below. (You are trying to connect CSE-H21 to the same serial software on your PC that you used to connect to PLC device previously) In that case, you may need to use ezVSP to connect CSE-H21 and your software on your PC. https://www.eztcp.com/en/download/ezvsp.php ezVSP is a virtual serial port driver and TCP/IP socket program, distributed for free by Sollae Systems. (ezVSP User Manual: https://www.eztcp.com/en/download/pds_files/an_ezvsp_en.pdf) If you still can not find any problem with your setting, could you please send us the screenshot of Serial and TCP/IP setting on your CSE-H21, and also let us know the configuration for the interface in your PC/your PLC with CSE-H21? Thank you very much for your understanding.

The PLC was then coupled using the official progamming cable (RS422)
