SIPLUS S7-300 CPU 315-2 DP Design
The SIPLUS S7-300 CPU 315-2 DP is equipped with the following:
the processor achieves a processing time of approximately 50 ns per binary instruction and 0.45 µs per floating-point operation.
- 256 KB work memory (corresponds to approx. 85 K instructions);
the extensive work memory for program sections relevant to execution offers sufficient space for user programs. SIMATIC Micro Memory Cards (8 MB max.) as load memory for the program also allow the project to be stored in the CPU (complete with symbols and comments) and can be used for data archiving and recipe management.
- Flexible expansion capability;
max. 32 modules (4-tier configuration)
- MPI multi-point interface;
the integrated MPI interface can establish as many as 16 connections simultaneously to S7-300/400 or connections to programming devices, PCs, OPs. Of 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 315-2 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/Os are treated the same as central I/Os (identical configuration, addressing and programming).
The PROFIBUS DP V1 standard is supported in full. This enhances the diagnostics and parameterization capability of DP V1 standard slaves.
