Vijeo Runtime Error

[djvb]

I am having an issue with a Vijeo Designer Runtime application fault code. I can't seem to find documentation on these.

Running Vijeo 6.3 and Control Expert sp15.1. Simulating connection between HMI and PLC I get :

'PLC returned error code. (FDH-8088H) (ModbusEquipment01)'

I have the same problem with Vijeo 6.2 and control expert V15.0.
If someone has a solution it would be great

If my latest tests aren't wrong :

The error code FDC-8088H appear when we're using variables directly from the exit of a function block or a %I.

When I put these into new variables and adress them in memory bits, theres no more error.
