NB Designer 1.39 and multiple HMIs won't work

[nednor 0]

In a project I did about two years ago, probably with NB 1.38 or 1.37 I had three NB10s on ethernet connected to a single CJ2M. 

So today I tried to create a similar project, with more than one NB on a CJ2M. Only problem is, I get an error saying "Only one NB can be accommodated within a project". Is it possible that Omron just figured they would change the software so that its not possible to use more than a single NB on new projects? Or am I doing something wrong or different from last time?

What I know since the very old release, only one NB is allowed on a single project, but multipe PLCs can be put on a same project.

But you are still able to connect multiple NBs to a single PLC through ethernet. You just need to Save As the project as a new one, and change the IP Address of the NB in that new project for the second HMI.

I suspected this. Thanks for the clarification.
