Features:
- The C240 PN places motion processing and local discrete signals in the same SIMOTION controller.
- PROFINET can organize subordinate devices or expose an I-Device data area to a higher-level controller.
- Network functions are enabled by defined SIMOTION release levels rather than one common software baseline.
Machine inputs and outputs remain local to the controller, while cyclic drive information follows the assigned PROFINET or PROFIBUS path.
Isochronous scheduling ties the controller task to the transmission cycle, so send-clock and application-cycle limits must be considered together.
Later SIMOTION releases extend the same hardware with media-redundancy and shared-device functions without changing its onboard signal count.
The Siemens 6AU1240-1AB00-0AA0 SIMOTION C240 PN Motion Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the IRT schedule is bounded
- Network interval: A 0.5 ms minimum send clock defines the shortest listed PROFINET transmission interval.
- Controller cycle: The application cycle is also listed from 0.5 ms, linking program execution to the network schedule.
- Synchronized roles: IRT operation is available when the unit acts as controller and when it exchanges data as a device.
- Station boundary: The controller role is documented for as many as 64 PROFINET devices.
How the communication roles differ
- Controller side: The PROFINET controller organizes cyclic exchange with the device group assigned to the machine.
- Higher-level exchange: The I-Device function exposes a defined data area to another PROFINET controller.
- Drive bus: PROFIBUS supplies the second documented communication route for connected drives.
- Shared operation: Shared I-Device is a later software function and is not part of the starting release level.
How local signals enter the motion program
- Input path: Eighteen onboard digital inputs place discrete machine states directly at the controller.
- Output path: Eight onboard digital outputs return locally calculated commands to field wiring.
- Processing relationship: The motion program evaluates local points alongside drive data received through the communication buses.
- Boundary: The onboard I/O count is independent of the number of devices organized on PROFINET.
How release levels gate network functions
- Starting level: Operation begins with SIMOTION V4.1 SP2 HF3/4 for this hardware.
- Ring protocols: MRP and MRPD are listed from SIMOTION V4.3.
- Shared-device level: Shared I-Device operation is listed from SIMOTION V4.4.
- Project check: The engineering project must match the release required by the selected network function.
