The CPU 314C-2 PtP is equipped with the following:

• Microprocessor;
  the processor achieves a processing time of 60 ns per binary instruction.
• Extensive memory;
  192 KB high-speed RAM (equals approx. 64 K instructions) for program sections relevant to execution offer user programs sufficient memory space;
  SIMATIC Micro Memory Cards (max. 8 MB) as load memory for the program also allow the project to be stored in the CPU (complete with symbols and comments).
• Flexible expansion capability;
  max. 31 modules, (4-tier configuration)
• MPI multi-point interface;
  the integrated MPI interface can establish as many as 12 connections simultaneously to S7-300/400 or to the PG, PC, OP. Among these connections, one is always reserved for programming devices and another for OPs. The MPI makes it possible to set up a simple network with a maximum of 16 CPUs via "global data communication".
• Second serial interface PtP;
  additional I/O devices such as printers, scanners, etc., can be connected via the serial interface.
• Integrated inputs/outputs;
  24 digital inputs (all can be used for alarm processing) and 16 digital outputs as well as 4 analog inputs and 2 analog outputs for current/voltage signals and an additional input for measuring temperature (Pt100) are available on the CPU 314C-2 PtP.
