Siemens 6ES7317-2EK13-0AB0 SIMATIC S7-300 CPU 317-2 PN/DP central processing unit is documented for the stated industrial control system role.

System function

Rebuilt from individual evidence

System position

Evidence and limits

Siemens documentation identifies this reference as a SIMATIC S7-300 CPU 317-2 PN/DP with 1 MB work memory, MPI/DP and Ethernet PROFINET connectivity.

Executes the S7-300 control program and exchanges process data through MPI/PROFIBUS DP and Ethernet PROFINET networks.

The inferred system position places this reference Sits between the S7-300 rack program and mixed PROFINET or PROFIBUS DP field networks as the central control node.

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 the S7-300 control program and exchanges process data through MPI/PROFIBUS DP and Ethernet PROFINET networks.
System position: Inferred system position: Sits between the S7-300 rack program and mixed PROFINET or PROFIBUS DP field networks as the central control node.
Upstream / inputs: Local signal modules and distributed PROFINET or PROFIBUS DP devices provide process data to the CPU.
Downstream / outputs: The CPU sends control outputs and network messages to the connected automation equipment.
Limitations: Unknown: installation-specific compatibility, firmware and configuration support, current unit condition, and commercial availability.
