Question:
What is the possible reason for a toggle button to change its status without being clicked on?
Solution:
This button must be linked to a PLC tag. Probably, something is making the PLC’s variable change its status, and SCADA is displaying its change in value.
It is important to remember that not only does the button write a value in the tag, but it also reads this tag’s value. This kind of problem can occur if there is any conflict in the logic of the PLC.
