Smart standard

The IEEE has started work on a smart transducer interface standard for sensors and actuators that addresses high-speed CANopen-based networks.

The new project, IEEE P1451.6, “Standard for A Smart Transducer Interface for Sensors and Actuators: A High-speed CANopen-based Transducer Network Interface for Intrinsically Safe and Non-intrinsically Safe Applications,” will establish a CANopen-based network for multi-channel transducer modules and will define a safe CAN physical layer.

It will define the mapping of IEEE 1451 transducer electronic data sheets (TEDS) to CANopen dictionary entries, as well as communication messages, process data, configuration parameter and diagnosis information.

There are many implementations of CANopen network interfaces based on the CiA DS 404 device profile. In order to use the IEEE 1451 TEDS concept and attain data compatibility from a single sensor to a high-performance closed-loop controller, TEDS parameters must be harmonised. The proposed standard will allow development of lean gateways and cascaded transducer networks that combines specifications in of IEEE 1451 and CANopen.

The project is sponsored by the IEEE Instrumentation and Measurement Society.
