How to implement schedule with TPG gadget in HMI
I try to implement a schedule using TPG in HMI, I want to heat a room using a schedule.
I make a program in project
In HMI project I make a new page, page 3 and I atach TPG Bool gadget
If I try to attach a variable to TPG Boll, select variable are empty
In variable brewser I have T17_Boolean_Scheduler but in HMI I dont have this variable. What can I do?
you are trying to use variable (instance of a TPG function blok) which is in another function block. This is possible, but it is usually not good idea, since you would broke the "encapsulation" provided by the function block. What might be better is to create a HMI function block template and use it in the HMI template.
