Uncmdrv1 error on UniDDE

Recommended Posts

Hi there,

I'm running UniDDE on a server 24/7 and I've written a script to read the PLC registers via the lblDDE commands. It was all working fine but after approx 7 days I got an error message(see attached file). I had to restart the server to be able to run UniDDE again.

Can anyone help me with this? Why this happens and what I  can do about it.
