ET 200M consists of standard and fail-safe modules. I configured safety-related I-Slave-Slave communication (FD-X modules) between ET200s (IM151-7 with F-CPU) and fail-safe modules on ET200M station. When I am using three standard modules (I/O) and two fail-safe modules on ET200m, everything is OK. But, when I add one or more standard modules (I/O) to ET200M then Fail-safe modules don’t work properly (I have error “Timeout detected by F-I/O”). Anybody knows where is a problem? HELP PLESE!!!!!

This communication is made in HW-Config see attachment "F-communication". And about everything else cares F-CPU automaticaly. As you can see on picture in attachment I made same communication with ET200s which is working fine. The F-monitoring-time of my module is 1500ms. Thanks for your time. Best regards pistik.
