Features:
- The C240 controller coordinates PROFIBUS, analog, and stepper-drive connections from one SIMOTION unit.
- Eighteen digital inputs and eight digital outputs bring local discrete signals directly into the controller.
- The SSI feedback channel monitors both encoder-supply short circuits and signal-wire breaks.
Siemens 6AU1240-1AA00-0AA0 separates local machine states from the drive paths: discrete signals use onboard I/O while motion connections follow their dedicated interfaces.
The SSI channel of 6AU1240-1AA00-0AA0 powers compatible feedback devices and changes its allowable cable reach with the selected transmission rate.
Software and memory-card matching are part of the 6AU1240-1AA00-0AA0 configuration because the supported card boot loader follows the SIMOTION release.
The Siemens 6AU1240-1AA00-0AA0 SIMOTION C240 Motion Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How command paths divide
- PROFIBUS drives: Cyclic drive communication uses the controller's PROFIBUS connection rather than the local I/O bank.
- Analog drives: Analog command paths remain distinct from the networked drive route.
- Stepper drives: Pulse-based stepper control uses the C240 hardware assigned to that drive type.
- Local signals: The 18 inputs and 8 outputs serve machine states and commands without replacing the drive interfaces.
SSI feedback relationship
- Feedback format: The synchronous-serial channel accepts single-turn or multi-turn SSI encoders.
- Channel power: The same interface supplies the documented 24 V encoder feed at up to 0.3 A.
- Rate and distance: Higher SSI transfer speed shortens the permitted cable run, from 250 m at 187.5 kbit/s to 10 m at 1500 kbit/s.
- Circuit checks: Short-circuit monitoring covers the sensor supply, while wire-break monitoring covers the feedback path.
Card and kernel matching
- Project medium: Controller project and boot information are held on a compatible SIMOTION Micro Memory Card.
- Card choices: The C240 documentation lists 32 MB and 64 MB card order numbers for this hardware family.
- Boot loader: The card boot-loader level must support the SIMOTION kernel loaded for the controller.
- Release check: A card suitable for one C240 release should not be assumed to cover every later kernel without verification.
Starting software condition
- Initial release: The listed operating baseline for this order number is SIMOTION V4.0 HF2.
- Project alignment: Controller hardware, SIMOTION project version, and memory-card boot files must describe the same supported release.
- Card compatibility: Later controller kernels require the corresponding tested card and boot-loader assignment.
- Commissioning record: Recording the installed kernel and card order number prevents version ambiguity during replacement.
