OMRON NT31C alarm lists

I can't believe that I am limited to 256 alarm messages! Are there any tricks or different ideas to get a lot more than that?

How about moving to NS5? 5000 alarms and 5000 events in Version 6?

Maybe next time we build a machine this big for this customer I could do that. I guess that is the frustration involved with quoting odd (to us) brand name hardware. I've got an assembly line with 3 of the NT31C's already and we are late as it is, so that's not an option this time.

you asked for it!

Well, what I have done in the past is set up a display area that will show an error code number, make a nice error code reference and place it at the machine, group a like codes together so a like codes have the same prefix, ex 1xx = air pressure, 2xx = cylinder and so on and so fourth. Then write some plc code to move the error code number to the display dm area on the display when the conditions are true. This is not the best but those 256 issues are very common on low end HMIs from all venders.
