Valve outputs | Command value status
–
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).
Activating the command value status function
The status message of the valve command value is a function of the valve outputs
and can be enabled on the parameter pages "VOx - General -> Status".
￭
Set the "Valve command value" parameter to "yes".
Status feedback is enabled. The status object of the valve output becomes vis-
ible in the ETS.
￭
Set the parameter to "no".
Status feedback is deactivated. No status object is available.
The feedback telegram is transmitted as soon as the status changes. An automatic
telegram transmission of the feedback takes place after bus voltage return, if the sup-
ply voltage of the actuators fails and returns or after an ETS programming operation
(possibly with a delay).
The status object does not transmit if the status does not change after the ac-
tivation or deactivation of device functions or new input command values.
Transmission only ever takes place after changes to the command value.
Setting the time delay of the command value status feedback
The state of the status message is not transmitted automatically to the bus after bus
voltage return or an ETS programming operation. In these cases, feedback can be
time-delayed with the time delay being preset globally for all valve outputs together
on the "General" parameter page.
￭
Set the parameter "Delay after bus voltage return" to "yes".
The status message is transmitted with a delay after bus voltage return or after
an ETS programming operation. No feedback is transmitted during a running
time delay, even if the valve state changes during this delay.
￭
Set the parameter "Delay after bus voltage return" to "no".
The status message is transmitted immediately after bus voltage return or
after an ETS programming operation.
