Dear Experts,

I need your help. I have a problem between Siemens S7 system (6ES7 417-4HT14-0AB0, firmware v4.5) and two CT95038/01 INTEGRATED FUEL VALVE (for main and pilot fuel gas),

sometimes secondary controller will be fault and all LEDs flash(CPU diag buffer attached), and then I have to restart the secondary controller, for restarting the secondary controller

there is no problem, the problem is when I switch off and switch on the controller, controller stop LED is flashing (it's a self-configuration and this is normal) but precisely the controller is running moment (changing stop LED to run LED), we are having a network fault signal with those two valves during 3, 4 or 7 seconds and this leads to our unit becoming a trip. Valves connected to the controller using DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 1790D-T8BV8B and there are convertor (c.2846.02 Gateway DN-CBM-DP, configuration attached) and siemens Profibus Y-LINK module connected to the controller by IM153-2 (Network Map attached). If you have any suggestions let me know, please. All necessary files attached.
