The communication object is enabled, if in
object "Block" 1 bit is parameterized with the option yes.
The output is inhibited (blocked) and the current control value is retained via this communication object. Blocking of the
output is implemented in accordance with the Priorities, page 50. Telegrams are still received during the block. The telegram
last received is carried out after the block is removed.
Telegram value:
15
The communication object is enabled, if in
object "Forced operation" 1 bit is parameterized with the option yes.
This communication object sets the output in a defined state and blocks it. If a telegram with the value 1 is received, forced
operation is activated and the output implements the programmed control value in %. Telegrams are still received during the
forced operation. If the value 0 is received, forced operation ends. The telegram last received is carried out, after forced
operation has ended.
Telegram value:
16
This communication object is enabled if in
set with the option yes.
Valve purge is triggered using this communication object.
Telegram value:
The purging cycle time is restarted if automatic valve purge has been activated at start-up of the device.
The purging cycle time will be restarted at the end of the actual purging period. The parameterized valve purging duration is
included here.
If the valve purge currently active is interrupted by a manual valve purge or a set value that achieves the parameterized
purge value, the purge cycle time is restarted.
If the active purge duration was less that the parameterized purge duration, this will not be taken into consideration. In this
case, the actual purge cycle time is shorter in duration by the active purge duration.

Function
Block
0 = output not blocked
1 = output blocked
Forced operation
0 = end forced operation
1 = start forced operation
Trigger valve purge
0 = end valve purge, valve will be closed
1 = start valve purge, valve will be opened
Note
A valve purge not undertaken due to a higher priority will no longer be undertaken.
The following functions are executed with telegram value 0.

A valve purge currently under way is interrupted.

The purge cycle with automatic valve purge will be restarted.
