After I turn the S7-400 off and then on again, everything look's OK but I cannotconnect to the slave S7-300 stationsvia the MPI Network. Only Downloading the HW configuration of the S7-400 solves the problem. Waiting for your response... Amit Felman Attachment Sinchro_current.zip (122 Downloads)

If so please update to: Firmware Updates for S7-412 CPUs V 4.1.1. It may fix a problem, especially if you access unavailable IO with your panels. Best regards J_Bell
