Mitsubishi D Registers

[godcixelsyd]

Hi all. I'm trying to find information on the last fault for an A1SHCPU. So far from my reading and understanding, this should be stored in D9008, and I have a list of what the stored amount would indicate. My only issue is I can't find a way to just see what is currently stored in registers, sort of like viewing data tables in RSLogix500. Is there something like this for mitsubishi? I'm using GXDeveloper v8. Thanks in advance!

The quickest way would be to write a line at the bottom of the program like

-| |-----------[MOV D9008 D100] -|

In monitor mode it will show the contents

I had thought of doing it this way... I was hoping there was a way to just view current values of all registers. Guess there isn't. Thanks!

There is a way to see the program data registers by clicking 'Device memory -MAIN'


And 'Diagnostics - plc diagnostics will tell you the fault.

I looked around and didn't see the 'device memory' tab you referenced, and the Diagnostics seems to tell you only a current fault, not a last active fault. I took your suggestion and modified it to
-[<> D9008 K0]-----------[MOV D9008 D100]
in hopes that if it is a fault which allows the scan to continue, that it will store it where I can see what it was afterwards. Thanks for you help!
