Does the error code 02H affect other variables from being updated on the HMI?


04 July 2022

The error "PLC returned error Code 02H" is showing on the HMI. Does this affect all variables in the application?

Product Line:
Vijeo Designer Runtime (all versions)

When the Vijeo Designer Runtime reports an error code 02H, (ie. when you have a variable with a device address that does not exist in the PLC), all the tags in the same packet as the illegal reference will not be updated. However, all other tags in the panel will still be updated normally.
