Features:
- Four closed-loop controller channels execute step and pulse control functions.
- Four analog inputs work with eight digital inputs and eight electronically protected digital outputs.
- The analog channels accept voltage, current, thermocouple, and Pt100 measurement signals.
Siemens 6ES7355-1VH10-0AE0 places four FM 355 S controller channels in one SIMATIC S7-300 function module.
Field measurements enter through the analog channels, digital inputs provide discrete conditions, and the digital outputs issue the step or pulse commands calculated by the controllers.
The front-connector wiring and 24 V DC load supply serve the field side, while the backplane interface exchanges controller data with the S7-300 CPU.
The Siemens 6ES7355-1VH10-0AE0 FM 355 S Four-Channel Control Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How measurements enter the controllers
- Analog paths: Four analog inputs accept the process values used by the four closed-loop controllers.
- Measurement modes: Each configured path uses the selected voltage, current, thermocouple, or Pt100 range.
- Temperature sensing: Thermocouple channels can use internal compensation or an external Pt100 compensation path.
- Discrete conditions: Eight IEC 61131 Type 2 inputs bring binary states into the module's control logic.
Step and pulse command paths
- Digital commands: Eight outputs deliver the binary step or pulse control actions generated by the controller channels.
- Protection: Electronic short-circuit protection limits faults on the digital-output circuits.
- Inductive loads: The permitted switching rate is lower for inductive loads than for resistive or lamp loads.
- Substitute values: Parameterizable substitute values define the configured output state when that operating function is invoked.
Conversion and controller timing
- Controller count: Four closed-loop controllers process the module's configured measurement and digital conditions.
- Resolution choice: The integrating converter can be set to 12-bit or 14-bit resolution according to the measurement task.
- Conversion time: Higher 14-bit resolution uses the longer conversion interval documented for each analog channel.
- Interference rejection: The selected 50 Hz or 60 Hz conversion setting coordinates measurement integration with line-frequency rejection.
Field-side and backplane boundaries
- Backplane boundary: Optocouplers isolate the channel circuitry from the SIMATIC S7-300 backplane bus.
- Shared module side: The four controller channels are not isolated from one another and must follow the documented common-potential limits.
- Field connectors: Two 20-pin front connectors carry the analog, digital, and load-supply wiring.
- Cable limits: Analog thermocouple and 80 mV paths use the shorter documented shielded-cable limit than the other analog ranges.
