Controlling values
To control the process acknowledgement, enter the desired value (TRUE or FALSE,
depending on whether you want to activate or deactivate acknowledgement) into the column
"Control Value" and click the icon with the two arrows.
Controlling variables
(1) Channel value
(2) Analog value
(3) Status
Peculiarity in monitoring the values
While monitoring the values you will surely notice that the channel values are different from
the analog values. The reason for this is that the analog module only supports the binary
format “Word” (16 bits). Therefore, the values of the analog module have to be converted.
