Omron NJ - FINS Communication

Is there a problem with the NJ processor and FINS communication?

I created a new project with a Variable "myInt" Array[0..100] Of INT with AT set to %D10 as shown


I can connect with citect using the OMFINS driver and read/write to D10 - D100
BUT
I can also read/write to areas outside of this range say D0 or D200 and cannot find the affected memory areas in sysmac studio.
This seems dangerous if I could potentially overwrite other memory areas.

I would make sure that your variable is global. See the above thread. Page 15 Creating Global Variables.

This may help you out.
