B0048191 / Rev. 1.5
9.7
Faults concerning keyboard
No.
Cause
55
Changing of system / program parameters is not
possible, for a serial fieldbus function is active (e.g.
Teach-In or Measurement start).
56
Changing of system / program parameters is not
possible, for a parallel function is active (e.g. Teach-
In or Measurement start).
57
Changing of system / program parameters is not
possible, since the parameter channel is opened via
Field bus.
9.8
Faults concerning supply voltage
No.
Cause
60
Operating voltage was below 20 VDC.
62
Sensor voltage too low.
9.9
Faults Sensor Switch Box
No.
Cause
65
Error in the Sensor Switch Box.
9.10
Faults concerning PLC parallel inputs
No.
Cause
71
The parallel function is not possible, because the
system was configured for the "demo mode".
72
The parallel function is not possible, because the
system is operated via the keyboard.
73
The parallel function cannot be performed because a
fieldbus function is active, e.g. "Teach-In" via the
fieldbus and "measurement start" via parallel inputs.
74
The parallel function cannot be performed because
the parameter channel is opened via Field bus.
