Function identifier
In the request telegram, which function should be executed in the device is signaled to the
BPS in the bits F0 to F7. The function identifier is entered in the response telegram. If the
function identifiers is defined, the BPS executes the desired function and sends the associ-
ated response telegram to the control. The following function identifiers are currently
defined:

Request position data:
Activates positioning mode when this is deactivated. Once a position
value is available, it is sent to the control. Positioning mode remains
active, and is only deactivated after 10 s. If a position value is requested
once again within these 10 s, positioning mode remains active (retrigger).
• Response time with deactivated positioning mode:
≤ 4 ms with BUSY response (see diagnostic data)
• Response time with activated positioning mode:
≤ 4 ms
• Minimum request interval: 10 ms
• Maximum request interval for retrigger: 10s
Request one-time transmission of position data:
Activates positioning mode; determines and sends position data once.
Positioning mode is subsequently deactivated (laser on – measurement
– laser off).
• Response time with deactivated positioning mode:
≤ 40 ms
• Response time with activated positioning mode:
≤ 4 ms
• Minimum request interval: 40 ms
Activate positioning mode:
Activates positioning mode; the BUSY response is sent immediately. The
bits DIA0 to DIA3 (see diagnostic data) and the bit OUT are set to 1 in the
status byte of the response telegram. 0 is sent as a position value.
If a request is sent after approx. 35ms with the function identifier
"Request position data" or "Request one-time transmission of position
data", this request is answered with a response time of ≤ 4 ms.
