Valve outputs | Command value status
–
Input command value "Constant (1-byte) with pulse width modulation (PWM)":
Data format of status object "1-byte",
–
Input command value "Constant (1-byte) command value limiting value":
Data format of status object "1-bit".
The status objects will assume different status values, depending on the input data
formats of the command values and the state of operation of a valve output.
The actuator distinguishes between different functions and events that can
have an effect on the valve outputs. Because these functions and events can-
not be executed simultaneously, there is priority control. Each global or output-
orientated function and each incoming event possesses a priority Priorities for
valve outputs. The function or the event with the higher priority overrides the
lower-priority functions and events.
Priority control also influences the status objects. That state is always trans-
mitted as the status which is currently set at a valve output. If a function with a
high priority is exited, then the status objects assume the command value of
functions with a lower priority, providing that they are active.
Status value for input command value "Switching (1-bit)"...
–
State of operation "Normal operation"
-> Status value = Most recently received input command value ("0" or "1"),
–
State of operation "Emergency operation" (0...100%)
-> Status value = Emergency operation command value ("0" at 0%,
"1" at 1...100%),
–
State of operation "Forced position" (0...100%)
-> Status value = Forced command value ("0" at 0%, "1" at 1...100%),
–
State of operation "Valve rinsing" (0%, 100%)
-> Status value = Current command value in rinsing operation ("0" when valve
closed, "1" when valve opened),
–
State of operation "Service mode" (0%, 100%)
-> Status value = Service command value ("0" when valve forcibly closed, "1"
when valve forcibly opened),
–
State of operation "After device reset" (0...100%)
-> Status value = According to presetting by parameter "Behaviour after bus or
mains voltage return" or "Behaviour after ETS programming
operation" ("0" at 0%, "1" at 1...100%),
–
State of operation "Manual operation" (5...100%)
-> Status value = Manual operation mode command value ("0" at 0% CLOSE,
"1" at 5...100% OPEN),
–
State of operation "Valve voltage failure" (0%, 100%)
-> Status value = Command value according to valve direction of action ("0"
when deenergised closed, "1" when deenergised opened),
–
State of operation "Short-circuit / overload" (0%, 100%)
-> Status value = Command value according to valve direction of action ("0"
when deenergised closed, "1" when deenergised opened).
