Protocols for position value output

d
(5A
h
):
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
91
d
(5B
h
):
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
92
d
(5C
h
):
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 tele
-
gram. 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.
