CAN bus protocol
CAN protocol:
CANopen
Device asyncsprofile:
CiA DSP 406, DSP 301 V.4,
DSP 305 (LSS)
Supported operating modes:
- Polling (async), data transmission on request.
- Cyclic, data transmission periodic, asynchronous
(async-cyclic) or synchronous (sync-cyclic) with sync
message.
- Acyclic, data transmission if process values change,
synchronous with sync message.
- LSS, layer setting service, simplified network
configuration.
Note:
The cable screen end and the encoder housing must be
connected to ground potential.
