Features:
- SIMATIC S5-95U compact controller architecture
- Second AS511 serial interface
- Onboard I/O with S5-100U expansion path
Siemens 6ES5095-8MC03 executes STEP 5 logic and exchanges process signals through integrated S5-95U resources.
The second AS511 interface on 6ES5095-8MC03 separates an additional serial communication path from the controller's primary engineering connection.
Bus units let 6ES5095-8MC03 extend local signal capacity with S5-100U I/O modules when the onboard points are insufficient.
The Siemens 6ES5095-8MC03 Compact PLC with Second AS511 Interface may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the extra AS511 path changes access
- Separate path: The second AS511 interface gives 6ES5095-8MC03 an additional serial connection beyond the primary controller interface.
- Engineering access: A programming device can use an AS511 path to exchange STEP 5 project and diagnostic data.
- Operator link: The other serial route can be assigned to a supported operator or communication task defined for the S5-95U configuration.
- Variant identity: The 8MC03 suffix identifies the S5-95U order configuration with the second AS511 interface.
From onboard signals to external modules
- Local signals: 6ES5095-8MC03 processes integrated digital, analog, counter, and interrupt functions without a separate CPU rack.
- Expansion bus: S5-100U modules connect through bus units when the onboard signal set does not cover the control task.
- Signal exchange: The CPU updates process inputs, executes the STEP 5 program, and then transfers results to the output area.
- Bus units: Each bus unit carries module communication and field-terminal connections for the attached external I/O.
Compact controller installation path
- Rail mounting: The S5-95U body of 6ES5095-8MC03 snaps onto a 35 mm standard mounting rail.
- Supply input: A 24 V DC source powers the controller and must be sized for the base unit and attached I/O.
- Expansion position: Bus units mount beside the controller so external I/O follows the local S5-100U bus path.
- Cabinet planning: Added bus units increase the station width even though 6ES5095-8MC03 remains a compact CPU.
How STEP 5 data reaches the controller
- Program transfer: STEP 5 engineering data enters 6ES5095-8MC03 through an AS511 serial connection.
- Cycle processing: The CPU reads process data, executes the stored control program, and updates output data each scan.
- Integrated blocks: Parameter blocks configure onboard functions such as analog processing, counters, interrupts, and communication.
- Diagnostics: Programming access exposes controller status and stored diagnostic information without changing the field wiring.
