ABC X-CPU-2 e57- the compact CPU solution after detachment of the Simatic S5-rack



The ABC X-CPU-2 e57 is a stand-alone PLC-System and consists of an ABC X-CPU-2 m57, a case e57 and is powered by a 24V input voltage. After detachment of the complete periphery of your S5 system by the ABC X-CPU-2 m57, you now have the opportunity in a final stage of your modernization to remove your S5 rack with the help of the case e57. You simply take the m57 out of the S5-rack and you easily get rid of your S5 system. You still don`t have an ABC X-CPU-2 m57? Here is an overview:


4 Gigabit CPs, 3 fieldbus masters and the unique opportunity to work on S5 and S7 programs simultaneously, the issue of retrofitting SIMATIC S5/S7 systems gives a new dimension.


  • PLC System for detachment of S5 racks and for new projects
  • Passively cooled system, easy installation
  • 24V input voltage
  • Command compliant to S7-CPU 416, also in Mixed Mode as 416-945/948
  • Quantity structure/Performance equates to S7-CPU417
  • Compatible to S5 CPU 945/948
  • Supports multiprocessor communication with up to 3x S5-CPU948 and 1x S7-CPU416
  • Programming in standard STEP5 and STEP7
  • Complete TCP/IP connection for linking of homogeneous and heterogeneous system components integrated
  • High Performance (average 10ns/operation)
  • Up to three fieldbus Master Profibus, Profinet, EtherCAT
