Siemens 6ES7315-2AG10-0AB0 SIMATIC S7-300 CPU 315-2 DP central processing unit

Siemens 6ES7315-2AG10-0AB0 SIMATIC S7-300 CPU 315-2 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 documents this reference as a SIMATIC S7-300 CPU 315-2 DP with MPI and a second PROFIBUS DP master/slave interface.

Executes the S7-300 control program and exchanges distributed I/O data over MPI and PROFIBUS DP.

The inferred system position places this reference Sits between the S7-300 rack program and distributed PROFIBUS DP stations as the central control and network 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 distributed I/O data over MPI and PROFIBUS DP.
System position: Inferred system position: Sits between the S7-300 rack program and distributed PROFIBUS DP stations as the central control and network node.
Upstream / inputs: Local signal modules and distributed PROFIBUS DP stations provide process data to the CPU.
Downstream / outputs: The CPU writes local and distributed output states to the connected control equipment.
Limitations: Unknown: installation-specific compatibility, firmware and configuration support, current unit condition, and commercial availability.
