Protocols for position value output
Leuze electronic BPS 8 108
TNT 35/7-24V
Behavior in the event of errors
If no current position data can be determined, the last valid position value will continue to be
transmitted, and the status bit OUT is set to 1.
In the event of protocol errors (e.g. incorrect target address, length, checksum), the request
telegram is discarded and no response is sent.
In the event of incorrect data (e.g. incorrect function identifier) and a correct telegram struc-
ture, the telegram is answered. In the response telegram, the unsupported function is
entered and the position value 0 is sent.
The BPS 8 currently switches the laser off after a request pause of 10s; i.e. if no valid
request is sent to the BPS 8 during this time, the position measurement is stopped. If the
BPS 8 receives a valid request once more, the laser is switched on and position measure-
ment is activated. Approx. 30 ms lapse until the request is answered.
