I have a Mitsubishi i-QR that has M and D registers allocated in memory that goes 600,000+. I have successfully created a connection to my PLC and have data coming to ignition, however, I am only able to see registers 0-65535 for both D and M. My PLC is currently configured for 0-614399. Is there a way I can access the registers above 65535?

It seems that right now it isn't possible, it looks like the address parser used by the driver is written with the assumption that the address can't be larger than 65535.

Oh man. That is no good. I will use a different route temporarily. Hopefully this can be fixed soon! Thank you for creating a ticket. Is there any way I can see the ticket and status so I know if/when it gets updated?

If you open a ticket with support and reference IGN-11784 they can "subscribe" you and keep you updated.

I also linked this forum post in the ticket, and sometimes somebody will come back and update after an issue has been fixed.
