I have six identical remote stations, which are connected to iX SCADA PC. In each station there is Crouzet PLC connected to GPRS modem over RS485. Modem converts Modbus RS485 to Modbus TCP and that's how SCADA takes data from stations.In iX Developer I configured six different Modicon Modbus masters (controllers). I chose Ethernet TCP/IP communication mode in each controller's settings.The problem is that then I start runtime I allways have one or few stations comm error. Then I restart runtime, comm err appears on other station. Looking at the signal state on modems parameters, signal is good. Also, then I launch modbus master software on my PC, the communication has no problems.Any ideas? Am I doing something wrong in setting up controllers in iX Developer?
I didn't find the right solution from the Internet.
