Hi,
I've tried to upgrade from OS3 on a V230 to the latest OS. The OS downloads ok but the ladder in the PLC needs to be compiled under the latest Visilogic. When I try to down load the ladder I'm getting a comms problem at the end of the down load, so it's not quite completing the download. I have reverted back to V3 of visilogic and all is fine.
Has anybody had a similar experience and found a way around the problem?
Cheers
Mat
