3. Encoder operating modes
3.1. Poll Mode
In Poll Mode the encoder will transmit upon request of another user. The data transferred may optionally
comprise position data or an additional warnflag and alarmflag.
3.2. Change of status Mode (COS)
The encoder will transmit position data without being requested by another user if the actual process value
has changed by a certain value (adjustable COS-Delta).
3.3. Cyclic Mode
The encoder will transmit position data without being requested by another user upon expiry of a
programmable time interval (adjustable 1...65535 ms).
