Reimo Posts: 14 Rating: (0)	Hi, Does anybody have experience Modbus TCP connection of S7-1200 as client and Ouman Ouflex heat controller as server? S7-1200 is v4, using TIA v13 Basic and using TCON_IP_v4. When using Modbus TCP client simulation PC software, I can get information from Ouman Ouflex. Also made PC based Modbus Server Simulation and S7-1200 can get information from that Modbus TCP server. So all setting should be okay! Tried almost everything but can not get data transfer going... I am getting error 80C8 Will add pictures of Ouman Ouflex and S7-1200 settings. Please help! Attachment 1-Ouman_IP.JPG (172 Downloads)

Kaulquappe Posts: 3093 Rating: (324)	Hello Reimo, which MB_Unit_ID do you use? S7-1200 uses 255 as default, most simulators use 1. Some 3rd party devices do not answer when they receive a request with an unknown UNIT. MB_Unit_ID is a parameter in the Modbus instance DB. Regards, Kaulquappe
