Variables in the text

You can display one variable per row in the text. This could be, for example, a measured value.

Procedure:

1. Insert a placeholder in any place you like in your text. The format of a placeholder is described below.
2. Link the variable "Value row x" (process data object Process image) with variables in a PLC program.
3. Assign values to the variables in the PLC program.
The display shows the values of the variables instead of the placeholders.

Format of a placeholder

The data type identifier specifies which data type the contents of the variables are to be interpreted as:

Note: the length of the text displayed changes with the size of the variable. If the value of a variable increases during operation, the text may be longer than 16 characters as a result. It is then displayed as scrolling text. This is often not desired for the display of values.

Predefined placeholders

In addition, there are two predefined placeholders that you can use in the text:
