What version of MAX and what version of the fieldpoint driver are you using? Check to see if they are up to date.
Take a look at this thread for advice where the person also had problems getting a cFP-RLY-421 board recognized.
Thanks for responding.
MAX version 126.96.36.19921
Fieldpoint drivers 5.02
The messages are "The module or item addressed does not exist" and "The device is offline. Make sure the device is connected and its power is on".
If I reset the cfp-2000, all relays activate on the cfp-421 (the eight indicator lamps light) for a few seconds and then go off.
I wonder if something is broken in the backplane because the cfp-421 power light is off.
Have you powered down the entire system, removed the modules, and reinsert them to make sure they are seated to the backplane correctly? Any chance of bent pins (unsure of what type connectors are used).
Yes, we have four cdp-rly-421 modules. I checked the pins and tried them all in different slots.
I just downloaded nifpsw606f1.exe to update the drivers.
