MX OPC Server DA/UA

[SolidRio]

I am trying OPC servers from mitsu (never worked with them before).

With UA version i have no problem.

When i configured connection in DA server and start "Monitor view". I always got "Cant connect to OPC server".

Reinstalled. Installed another version (7.02, 6.10). But problem the same. 

I've installed on another laptop with the same system (7 x64), but without many plc soft here (only gx works 2 and gx developer) and it works without problem.

I thinking some soft is blocking it. Maybe someone faced this problem before.

p.s. Already second topic in one week with asking for a help, god....

Most likely the problem is with DCOM. OPC DA uses DCOM for security so you have to make sure that the user running the DA client has access and launch privileges with the DA Server. We have found over the 20 plus years that we have been dealing with DCOM that you can have 2 PC's configured with the exact same OS image and that you can get an OPC DA connection on one PC and not the other. This is one of the many reasons so many people are adopting OPC UA over DA. It has better security and you do not have to deal with DCOM.

Check with the DA client or sever vendors should have documentation their DCOM recommendations. The OPC Training Institute has some good resources for this as well.
