Operating mode of the encoder
3.1
Poll Mode
In the Poll mode, the encoder transmits at the request of a different user. The transmitted data can be either
position data or additionally to the position data, also contain a warning flag and an alarm flag.
3.2
Change of state Mode (COS)
The encoder transmits position data without a request from a different user, when the current process actual
value has changed by a certain amount (adjustable COS delta).
3.3
Cyclic Mode
The encoder transmits position data without a request from a different user after expiry of a programmed time
interval (adjustable between 1 and 65535 ms)
