Siemens SIMATIC S5/S7
With these controllers, you can determine the
reaction of the valve terminal to the following
faults:
• controller failure
• bus interruption
• program stop
Almost all configuration programs contain the
function "response monitoring". For the operating
modes named, the specified time represents the
failure time of the valves and electrical outputs.
Please refer to the relevant manuals for further
details on response monitoring.
General DP-master
By means of the function
Set_Prm
, you can
determine the watchdog time (WD_Fact_1, Octet
2, WD_Fact_2, Octet 3). In the case of a fault,
e.g. bus failure etc., the valve terminal switches
all valves and electrical outputs off after the
parametrized time.
