Formula for Scaling the Output:
Scaling is always performed on the variable in the operating terminal. Through
scaling, the measured values collected in the controller are adapted to the operator
guidance. The output representation is determined by
formula 1 only. Unlike the
factor and divisor, the summand (representing an offset) can be set to the value 0.
Before a variable or constant is output on the display, it is converted as follows:
PLC value × Factor
Terminal value = + Summand
Divisor

Output Representation Types:
Certain types of variables can be recognized more easily if they are displayed in
their own specific format. A type-specific representation makes interpretation of the
variable content easier. For this reason, a wide range of representation formats is
provided.
Examples:
-
Input statuses of an input module Binary representation
- Filling level of a container Bar (bar chart)
- Temperature Curve (line graph)
- Valve states Graphics showing valves
Example of a coded text used for outputting an end position condition:
Binary Hex Decimal Selection Text (Coded Text)
0 00 0 Not in end position
1 20 32 In end position
Representation With Leading Zeros:
The option of displaying leading zeros can be used in conjunction with every in-
teger. Leading zeros are required in particular for displaying dates and times and
hexadecimal or binary formats. The ‘Display Leading Zeros’ option can be selected
in the variable definition.
