IMPORTANT:
To ensure that the value is overwritten by other display devices that do not have the temperature
sensor, it is a good idea to set up an additional condition. If the value
uBT_Watch,Tempera-
ture,value
is "empty" or has the default value defined in the WVAR, the function will not be exe-
cuted.
A number of sensor values in the same application which are executed on different panels:
It is also possible to transfer to the controller a number of sensor values in the same application
which are executed on different panels. In order to do this, each panel must be clearly identified.
The
MB_PERCO_x
provides a variable which is saved in the panel in a remanent manner.
1) Steps 1 to 5 described previously are identical and must be carried out. In contrast, the write op-
eration must be expanded.
2) In order to save the values of different panels, an array must be created in the symbol editor.
3) In Panel 1, the INT variable
MB_PERCO_1
is written with a function or entry field. The value in
the INT variable
MB_PERCO_1
specifies the position of the current panel in the array created.
4) The user project must now use the
MB_PERCO_1
variable when searching for the array. In or-
der to do this, the symbolic name of the PCD variable must be searched for dynamically.In the
web application, the internal variable must now be included in the resolution of the PCD varia-
ble.
The
@CO_ MB_PERCO_1@
in the PCD variable is used for this purpose. The panel will now
use the locally defined value in
MB_PERCO_1
in order to request the PCD variable.
