ABC X-CPU-2 m57

The ABC X-CPU-2 m57 is a central module for use in the automation systems of the SIMATIC S5 by Siemens. The module is programmable in STEP5, STEP7, PCS7 and TIA by Siemens and is suitable for restructuring and upgrading projects.

Integrated is the multiprocessor operation with up to three S5 CPUs and one S7 CPU.

In addition the m57 offers an expanded operating functionality for asynchronous handling of fast processes.

4 Gigbit CPs, 3 fieldbus master and the unique opportunity to work with S5 and S7 programs simultaneously, give the subject of retrofi SIMATIC S5 systems a new dimension.
