Special functions of the PLC interface
1)
Pin
Error messages Fault status 0: Warning O/23
Monitoring the buffer zones and controlling the parts
supply with switch hysteresis
Buffer zone sensor 2
2)
I/13
Additional test of material features which are not chec ked
during contour registering (e.g. by metal detector or
colour sensor). Downstream-switched test function,
e.g. only good par t s are checked.
External sensor
3) 4)
I/10
Externally controlled switching on/off of the picture
registration under particularly difficult conditions.
Camera trigger I/9
Such as for monitoring the pneumatic supply fo r th e
actuators: In the event of a fault, the CHB-C-X will be
switched to fault status E 01 by means of a pressure
switch.
External fault I/19
1)
Deactivated at t he factory Functions can be activated and adapted with CheckKon.
2)
Can be set optionally with CheckKon, set at factory “External type selection: bit 2”.
3)
Counter function and special function “External sensor” cannot be use d at the same time.
4)
Can be set optionally with CheckKon, set at factory “External type selection: bit 3”.
