TECT_TEMP_CONTROL_VISU_PHΒΆ
Description
Visualization element TECT_TEMP_CONTROL_VISU_PH is used to show the actual values of all inputs and outputs of the instance of TECT_TEMP_CONTROL_VISU_PH. The visualization is also used to control the Function Block by those inputs, which are not connected inside the program. The figures show the visualization in offline and online mode.

All inputs of TECT_TEMP_CONTROL Function Block, which are not connected to a variable (left open), can be written from this visualization faceplate. The Function Block can be controlled from the visualization as long as the inputs are left open.
The color of the background can be changed by writing a value to the global variable dwTectControlVisuBackgroundColor. The color of the title can be changed by writing a value to the global variable dwTectControlVisuTitleColor.
