Hi,
I don't have many experience with ET200S with CPU capabilities so if someone can help with configuration. As I have seen the IM151-7 cpu is a slave. Network topology would consist of 2 field profibus transmitters, a siemens HMI panel and a IM151-7 cpu (et200s cpu). Do I need an additional master module for IM151-7 cpu for this to work and exchange data so that the IM151-7 is the master in the network or is this module unnecessary for this configuration? Sorry if it is basic question but I have never used et200 cpus as the only cpus in the network (I always used s7-300 as masters..)
