Enter a text that replaces the value "1" of the process value (for example, "ON").
Enter a text that replaces the value "0" of the process value (for example, "OFF")
Enter a text for the physical unit (for example, "I/s").
Here, you specify the format of the value to be written to the SD card or displayed in
the tag table.
With analog inputs the box has the default [V.2].
With counters the box has the default [V].
Note the following rules:
The square brackets and the letter V R placeholders for the tag name. They must not
be changed.
The period and the digit following it indicate the number of decimal places (max. 6). If
you write the values of a tag to the SD card only with 1 decimal point or want to
display them in the tag table, configure the parameter as follows: [V.1]
