You can configure the desired output signals in the column Expression on the tabs Analog and Digital in the signal tables, just like for the virtual signals. To define the output signals, use the expression builder, which will again provide you with all options for the mathematical and logical calculation. You may enter simple numerical or Boolean equations or complex mathematical expressions. The expression builder is the supporting tool for the creation of mathematical expressions. If you know the syntax, you may also manually enter the expressions in the table. Use the button <fx> to open the expression builder.

For more information about the expression builder, please refer to part 4 Expression .

Remember that the result of the expression must match the signal's data type.

Virtual analog signals are always REAL type values. If the connection mode is set to “Integer,” the analog output signal will be rounded to the nearest whole number (integer). In order to get a virtual digital signal or alarm, the result of the expression must be a Boolean quantity (TRUE or FALSE).
