Error Treatment
Reaction to faults in the control system
PLEASE NOTE
If all outputs are reset after a PLC stop or if
there is an interruption or fault in the field
bus, the following "pneumatic rules" must be
observed:
•
unilaterally actuated valves assume the
basic position
•
double solenoid valves remain in their
current position
•
mid-position valves assume the mid-
position and (depending on valve type)
are pressurized, exhausted or blocked.
