Product overview

2.2 Configuration and operating principle

You mount the CPUs on a common mounting rail or spatially separated on two separate

mounting rails. You connect the two CPUs with fiber-optic cables to two synchronization

modules in each CPU. You set up the PROFINET ring with the PROFINET interfaces

X1 P1 R and X1 P2 R of the CPUs.
