Thanks to the interchangeability of the connectors on the upper side of the CPU, digital and analog IOs can be exchanged from one CPU to another one, without these having to be recabled completely. Allowing you to act even more flexibly.
Up to three communication modules can be mounted on the left-hand side of each SIMATIC S7-1200 CPU - making point-to-point communication, PROFIBUS master / slave, GPRS communication, AS interface and further fieldbus systems possible.
This allows you to solve your application-specific requirements flexibly. Pluggable terminals for the complete range of products allow rapid and efficient exchanging of CPUs and signal modules.
