Features Applications Model

Microprocessor; the processor achieves a processing time of 100 ns per binary instruction.
Extensive memory; 32 KB high-speed RAM (equals approx. 10 K instructions) for program components relevant to execution offers sufficient space for user programs;
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. 8 modules (1-tier configuration)
MPI multi-point interface
The integrated MPI interface can establish as many as 6 connections simultaneously to S7-300/400 or to programming device, PC, OP. One of these connections is always reserved for the PG and another one for the OP. The MPI makes it possible to set up a simple network with a maximum of 16 CPUs via "global data communication".

CPU 312, the smallest S7-300 CPU. This is ideally suited to simple applications in which the advantages of TIA such as integrated communication, data management and diagnostics can however be utilized. Networking is possible using MPI or by means of CPs, the standard mode of application is, however, non-networked operation. The I/O is normally connected in a centralized configuration.
