Hi,
I am trying to get a basic safety application to download but I keep getting an "Invalid ERR Ack input" and "The Standard Inputs Size of zero is not allowed".
I am simply using 2 safety inputs through an "AND" block to 2 safety outputs. Any help would be appreciated.
I had a similar error "Invalid ERR Ack input". What you need to do is link an variable from the "non-safe" PLC to the Group IOs of the POU in the Safety app.
* Add a POU to the SafetyApp (probably already done, otherwise you don't get this error)
* Right click on this POU - select properties
* Go to the Group IOs tab
* Link a variable to the Err.Ackn. input
I don't know about the Size of zero, I didn't get this error. Were you able to fix this?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
