By reading in profile bar code nos. 11 and 12 (
Section 10.2 Default setting
), you can
define the above default settings temporarily with a different parameter set to allow
the PC to communicate with the CLV.
8. 5. 2 Connecting the functional interfaces
Sensor 1 switching input
In order to trigger a reading process, the CLV requires a suitable clock pulse in
Reading mode that signals the presence of a conveyor object in the reading field.
The clock pulse generates the reading interval (time window for evaluation) internally
in the CLV. In the default setting, the reading pulse is supplied by means of internal,
continuous reflector polling (see
Section 9.2
).
If an external sensor (e.g. photoelectric switch, switch) is to notify the CLV of the
presence of a conveyor object, the following steps must be performed:
