Link a button in Wonderware from 2 different PLC’s

[Ones_Zeros]

Hello
I was wondering how to link a button in Wonderware to two different PLC’s?
This button is a reset button that resets both PLC’s.

- one plc is a Modicon
- second plc is a AB compact logic
- the two tags are already configured in Wonderware.
- I would assume that a data change script would work, but can’t seem to get it to work.
- can a script be configured to where when the button is pressed, it will operate both bits in the PLC’s to reset both PLC’s?

Thanks for helping

I don't understand what you mean by "resetting" the PLCs.

That said, you should be able to make the HMI pushbutton tag a Memory Discrete and have a condition script that runs whenever the pushbutton tag == 1 and sets the IO Discrete tags for the PLCs to a value of 1.

You could then reset the IO Discrete tags in the PLC logic or have another script reset them in the HMI.

Use button script and you can set as many tags as you want.

Each of the PLC’s (Modicon & Allen Bradley) have a bypass and reset bit. The reset bit resets any unlatched bits to latched state and the bypass bit will bypass a bit during testing or maintenance to prevent a shutdown.

I do appreciate the detailed explanation you gave, it helps me to configure this in WW.

Thanks again
