Features:
- Mixed analog, digital and counting channels concentrate process wiring in one AddFEM unit.
- Two parallel PROFIBUS DP interfaces exchange channel data with the Add 7 processor.
- Module and load supplies follow separate paths for analog and digital output circuits.
The front end converts field states into bus data before the automation processor executes control logic.
Output commands return over PROFIBUS DP and are applied through the corresponding channel circuitry.
Local LEDs and short-circuit monitoring identify channel conditions at the cabinet.
The Siemens 6DL3100-8AA AddFEM Front-End Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Organizing measured values and analog commands
- Current inputs: Six channels accept the documented current signal path.
- Selectable inputs: Six additional channels are configured for current or voltage measurement.
- Output words: Eight processor commands become analog field signals at the output terminals.
- Supply path: Analog output circuitry receives its 24 V path internally from the module.
Separating status, pulse and load circuits
- Input states: Fifteen channels return discrete field conditions to the processor.
- Pulse counting: Three assigned inputs accept the documented counting pulse function.
- Output assignment: Sixteen channels drive loads or can be configured for digital input use.
- Load feed: External 24 V DC enters at X7 for the digital output circuits.
Relating the two DP links to Add 7 control
- Parallel interfaces: Both PROFIBUS DP paths connect the front end to the automation processor.
- Data exchange: Input values travel upstream while output commands return to the module.
- 8AA behavior: Redundancy coordination resides in the automation processor for this exact version.
- Version boundary: The later 8AC architecture must not be assigned to the 8AA article.
Mounting and supervising the open equipment
- Housing: The stainless-steel assembly protects the internal channel electronics.
- Mounting choices: The unit fastens to the documented rail or wall arrangement.
- Open equipment: A suitable cabinet provides the required environmental protection.
- Local checks: LEDs and short-circuit monitoring support channel-level inspection before bus diagnosis.
