Standard Mode
The display area is between 0,00 and 655,35. If the check box Only
Positive is not selected, the display area changes. The value is dis-
played with a sign. You must specify an additional position in the field
length for the sign. The following data is required:
– Decimal number
– Output
– Field length = 7 (5 + decimal point + sign)
– Fractional digits = 2 (absolute)
The display range is then between –327.68 and +327.67.
5.5.16 Input Variables
When displaying input variables for the first time in the operating
device, the system uses the same approach as for one-off output vari-
ables (output variables that are output only once). This also applies to
scaling, which works from the controller’s viewpoint.
Input variables are processed by editors in the operating device.
5.5.16.1 Plausibility Check
The system carries out a plausibility check for all input variables. Dur-
ing this check, it compares the value entered with the range limits
stored in the variable list.
If the limits are not adhered to, the system issues one of the following
system messages:
– 'Value too large' or
– 'Value too small'
The incorrect value is not written to the controller. If an error occurs, the
previously valid value is retained.
To prevent the above-mentioned system messages from appearing,
you must delete them in the programming software. When you do this,
the following applies:
– If the value is exceeded, the value of the upper limit is entered
– If the value is not reached, the value of the lower limit is entered
