Special functions of the PLC interface
1)
Pin
Fault 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 checked
during contour registering (e.g. by metal detector or colour
sensor). Downstream−switched test function, i.e. only good
parts are checked. External sensor
3) 4)
I/10
Externally−controlled switching on/off the picture registering
under particularly difficiult conditions. Camera trigger I/9
E.g. for monitoring the pneumatic supply for the actuators: In
the event of a fault, the CHB−C−P/..X will be switched to fault
status E01 by means of a pressure switch. External fault I/19
