Microprocessor; the processor achieves a processing time of 70 ns per binary instruction.
Extensive memory; 128 KB high-speed work memory (equals approx. 42 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).
MPI multi-point interface; the integrated MPI interface can establish as many as 8 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".
Integrated inputs/outputs; 24 digital inputs (all can be used for alarm processing) and 16 digital outputs as well as 5 analog inputs and 2 analog outputs for current/voltage signals and an additional input for measuring temperature are available on the CPU 313C.
