This function block is used for the visualization of BIT values.

The color change indicates if the input In is HIGH or LOW.


The parameter dialog can be used to define the size of the function block, the colors for the two states and the frame, the form of the LED and the general display mode.

*This function block normally only uses the BIT data type, but other signals can be connected to the input, too. If no BIT signals are used, the data type will be converted. In this case the user is asked to specify the offset to identify the relevant byte. The function block will interpret this byte in the way that a value not equal 0 is used as "on" and a value equal 0 is used as "off".


This function block has no corresponding target code. During online observation the values are read and represented cyclically.
