Hey there.
I have a ML1400 PLC and a PV800 HMI.
I have a problem with pushbuttons in the PV800.
I want to create a button that can be activated on the HMI, and change state back to '0', when i change state of the bit in the PLC. How do I do that!?
I have created a maintained pushbutton, and assigned a write tag.
'0' is yellow an '1' is green. When i press the button it activetes the bit in HMI and in the PLC to '1'- When i change the state in the PLC it change state to '0' in the PLC but its still green on the HMI!?
I have tried using a latched button. It works the same way. When i change state in the plc it is still green on the HMI. I can press the button again and it activates the bit, but it doesnt change color?
Has it something to do with indicator tag? I have only assigned a write-tag.
I'm programming it in CCW.
