For more information on switching over of the operating mode, refer to the "Switchover of
operating state and operating mode" section in the APL Online Help.
(2) Opening, closing and stopping the control valve
This area shows you the default operating state for the valve. The following states can be
shown and executed here:
● "Open"
● "Close"
● "Stop" (display only, no operation possible)
"Close"/"open" command relates to the auxiliary valve. If no auxiliary valve is required for
controlling the control valve, the "Open" and "Close" commands affect the control valve.
If text is configured for these commands, it is displayed as status text and as button labels for
command selection. You can find additional information on this in the "Labeling buttons and
texts" section in the APL Online Help.
For more information on switching over of the state, refer to the "Switchover of operating state
and operating mode" section in the APL Online Help.
(3) Displaying and switching the default manipulated variable
This area shows how to specify the manipulated variable. The manipulated variable can be
specified as follows:
● By the application ("External", CFC/SFC)
● By the user directly in the faceplate ("Internal").
For more information on switching over of the manipulated variable specification, refer to the
"Switchover of operating state and operating mode" section in the APL Online Help.
(4) Resetting the block
Click "Reset" for interlocks or errors. For more information, refer to the "Resetting the block in
case of interlocks or errors" section in the APL Online Help.
(5) High and low scale range for the manipulated variable
These values provide information on the display range for the bar graph of the manipulated
variable. The scale range is defined on the Sipart and read by the block there.
(6) Displaying and changing the manipulated variable including signal status:
This area shows the current manipulated variable with the corresponding signal status.
The manipulated variable can only be changed by
● Internal manipulated variable specification (MV_ExtAct = 0) and
● an open auxiliary valve (due to the dependence on the standard function "Neutral position
for motors, valves and controllers" that is described in the APL Online Help).
