1.1 What Is the IM 151/CPU Interface Module?
What Is the IM 151/CPU?
The IM 151/CPU is a component of the ET 200S distributed I/O system with IP 20
protection. The IM 151/CPU interface module is an intelligent preprocessing unit
(intelligent slave). It enables you to decentralize control tasks.
An ET 200S with an IM 151/CPU can therefore exercise full and, if necessary,
independent control over a process-related functional unit and can be used as a
stand-alone CPU. The use of the IM 151/CPU leads to further modularization and
standardization of process-related functional units and simple, clear machine
concepts.
How Is the IM 151/CPU Integrated in the ET 200S?
The IM 151/CPU interface module is integrated in the ET 200S in the same way as
any other module. In other words, its configuration concept, installation and
expansion capability are the same.
