Microprocessor; the processor achieves a processing time of 60 ns per binary instruction
Extensive memory; 192 KB high-speed work memory (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).
MPI multi-point interface The integrated MPI interface can establish as many as 12 connections simultaneously to S7-300/400 or connections to programming device, 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".
PROFIBUS DP interface: The CPU 314C-2 DP with PROFIBUS DP master/slave interface allows a distributed automation configuration offering high speed and ease of use. From the user's point of view, the distributed I/O is treated as central I/O (same configuring, addressing and programming).
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 (Pt 100) make the CPU 314C-2 DP a high-value control.
