System function
Rebuilt from individual evidence
System position
Evidence and limits
Siemens documents this reference as a SIMATIC S7-300 CPU 315F-2 PN/DP with 512 KB work memory, MPI/DP, Ethernet PROFINET with a two-port switch and Micro Memory Card support.
Executes standard and safety control programs and exchanges safety or standard process data through PROFIBUS DP and PROFINET.
The inferred system position places this reference Sits between the S7-300 safety control program, distributed I/O networks and the controlled machine.
Unknown: installation-specific compatibility, firmware and configuration support, current unit condition, and commercial availability.

System role
This section explains what the product does and where it acts in the surrounding system.
- Function
- Executes standard and safety control programs and exchanges safety or standard process data through PROFIBUS DP and PROFINET.
- System position
- Inferred system position: Sits between the S7-300 safety control program, distributed I/O networks and the controlled machine.
- Upstream / inputs
- Distributed PROFIBUS DP or PROFINET I/O provides process and safety inputs to the fail-safe CPU.
- Downstream / outputs
- The CPU sends standard and safety output states to the distributed control equipment.
- Limitations
- Unknown: installation-specific compatibility, firmware and configuration support, current unit condition, and commercial availability.
