Error handling
5.5.1 Behaviour during faults in the control system
In the case of the following faults, the Festo valve terminal
type 03/04-B is dependent on the configured behaviour of
the master interface:
–
telegram failure
–
master stopped
–
interruption in bus cable
Depending on the setting or configuration, all the outputs
(valves and electric outputs) will be switched off or retain
their status.
Warning
Make sure that valves and outputs are reset when the
faults named occur.
This prevents hazardous situations.
Please note
Unilaterally-actuated valves move to the basic position.
Double-solenoid valves remain in the current position.
Mid-position valves move to the mid position and are (de-
pending on the valve type) pressurized, exhausted or
locked.
Notes for general DP master
With the function Set_Prm you have the possibility of deter-
mining the watchdog time (WD_Fact_1, Octet 2, WD_Fact_2,
Octet 3). In the event of an error, e.g. a bus failure, the valve
terminal will switch off all the valves and electric outputs
after the parametrized time.
