The profile specifies five classes of single/double ASI-controllers ranging from an M0 ASI single controller (controls up to 31 ASI-devices) to an M4 ASI double controller (controls up to 124 ASI-devices). Depending on the supported controller functionality up to eight TPDOs (transmit process data objects) and RPDOs (receive process data objects) are pre-defined.

The application objects include digital and analog inputs as well as digital and analog outputs for up to 124 ASI-devices in two circuits. Each analog input and output has four 16-bit channels presented as four Integer16 values. The specified ASI-controller flags inform about the possible signal periphery or power failures, configuration status, automatic addressing functionality, as well as about the modes (e.g., normal, off-line) of the controller. The ASI-controller control word allows switching the controller into a certain mode (on-line, off-line, configuration, protected run-time), storing actual configuration, enabling/disabling automatic addressing, and data exchange. The according ASI-controller status word shows whether the required commands were executed correctly. Further, optional lists of active ASI-devices, detected ASI-devices, and of peripheral faults are provided. A possibility to write and to read a list of projected ASI-devices is given. Reading actual ASI-device configurations (e.g., ID code, I/O configuration) as well as writing and reading the permanent ASI-device configuration may be done via appropriate objects. Additionally, the information may be acyclically read/written from/to each ASI-device. The read/write response is then available on the CANopen network via specified objects.

For devices compliant with the profile, it is recommended to use connectors and pinning assignments according to CiA 106. The physical layer definitions follow those in CiA 301. For node-ID assignment via the CANopen interface (e.g., for IP67-rated devices), it is recommended to use the CANopen layer setting services (see CiA 305). Support of the emergency message and the heartbeat functionality is mandatory.
