7.8.1.2.2
Send status values
Options:
On request
On change
Cyclically
After a change or on request
After a change or request and cyclically
This parameter defines when the valve output status value are to be sent. It affects the group ob-
jects
Status byte valve A
,
Fault: valve output A
and
Status Control value
for the valve drive.
•
On request
: The valve output status values are sent on the receipt of a command via the
Request status values
group object.
•
On change
: The values are sent on a change in the object values (e.g. change from 0 to 1).
With the
Status Control value
group object the values are only sent if the change in the control
value is at least 1 %.
•
Cyclically
: If this option is selected, the status values are sent automatically after an adjustable
time has elapsed. The
Every
dependent parameter is displayed.
•
After a change or request
: The values are sent on request and on a change.
•
After a change or request and cyclically
: The values are sent on request and on a change and
cyclically. The
Every
dependent parameter is displayed.

This parameter is used to set the time after which the status values are to be sent cyclically. The
group objects are sent after each cycle.
7.8.1.2.3
Enable manual valve override
Options:
No
Yes
Manual valve override is enabled using this parameter. This feature is used to specify valve control
values directly; the control value from the controller is overridden. This action may be necessary
during the commissioning phase, for example, to test the function of the system. A further possible
application is the specific overriding of controller.
•
No
: The manual valve override is deactivated
•
Yes
: The manual override is enabled. The two group objects
Enable/disable manual override
valve A
and
Override valve control value
are enabled. The former is used to activate or deacti-
vate the manual override. The manual valve control value is specified using the second group
object. Only if the manual override has been activated via the first group object is the value in
the second group object sent to the valve. As soon as the manual override is ended using the
Enable/disable manual override valve A
group object, the valve output reacts again to the con-
troller (controller mode) or the control values received via the bus (actuator mode).
Note
As soon as the manual override is activated via the
Enable/disable manual override valve A
group object, the value currently in the
Override valve control value
group object is written to the
valve. If, while the override was disabled, a value was written to this group object, this value will
become active as soon as the override is enabled.
