Replacing an iQ-R04 CPU with an iQ-R04EN CPU

[cottagewood]

Module Configuration in GXworks3,
I have a configuration with an R04 CPU and Slot 0 is empty
Does anyone know how to replace the R04 CPU with an R04EN CPU?.

You would think this would be straight forward.

Under the menu Project/Change Module Type you can select an R04EN but you get an error telling you there is no RJ71EN71 to the right of the CPU.
So I put an _RJ71EN71 in Slot 0 but then get an error telling me that the CPU to used in conjunction with it is not mounted.

You need to select the module for slot 0 from "CPU Extension" in the element selection window not from "Network Module"

Yep, that's what I did, the _RJ71EN71 is a "CPU Extension"

Can you post the project (you can delete the logic), so that I may give it a try?

I'm out on the road of the moment, but if you create a new project with a r04 CPU, leave slot zero empty and put any Io card at slot 1.Then try changing the CPU to an r04en

Yes, it seems when you try to change from R04CPU to a different type, there is a limited choice of CPUs that can be selected, R04EN not included. It seems you need to create a new project with the R04EN, reassign the IO and copy+paste the logic. Sorry for not being able to provide more help.
