CClink Intelligent connection Q3UDE to Q2H

[wzrdstrm 1]

We have a system that was put together by a Japanese company. There are three devices exchanging data. A GOT1000 for the operator interface, the machine control running a Q2H CPU, and a Q3UDE that gathers production information from supporting processes. They are all exchanging data via CClink. Need some direction on how this is setup so I can follow the data from PLC to PLC. I was trying to upgrade the 2QH to a Q3UDE, which mostly worked, but appeared to have a CClink issue.

You can find a fast little training on  CC-link here.

But in general one of the PLC's will be a  master in the network where the two slave have been set-up.
You should be able to find that in the network settings.

Each slave is setup to have a nr of station for each station 4 Words and 32 bits are exchanged. (Called RX,RY,Rwr,Rww)
These are copied on the PLC to standard devices in the refresh setting.

Thanks Gambit, 

When I do a read all, are these settings captured? It appears something did not get read, or I have to modify something due to new CPU type. 

I download a crap of those trainings....not sure about the linked one though, so will do that now.

Yes should be in the parameter upload.
