Request telegram structure
Description
Bit ON:
If this bit is set to 1, measurement operation and the cyclical output of position data are
activated. The position data are transmitted cyclically from the BPS.
Bit OFF:
If this bit is set to 1, measurement operation is deactivated and the cyclical output of data
is stopped. If measurement operation and the cyclical output of position data are re-acti
-
vated, the boot time is 5 s.
Bit DIAG:
If this bit is set to 1, diagnostic data can be requested. An indicated error is reset once all
diagnostic data has been polled. This is indicated by the status LED changing from red to
green.

NOTE
It is advisable to set only one bit in the request byte, as the BPS can only answer one request
at a time. If several bits are set, the function with the highest priority is executed.
