Hello, having some issues on a Micro820 to a EA9-T8CL panel. Pops up with an error "PLC-498 " "0x050000 " on the screen, it seems like it's not communicating properly, dropping 2 bytes of data in the error screen. Made a simple program on the 820 with a closed input to energize a coil that I tagged for the HMI to pick up on an indicator light. HMI will not pick it up, set the IP addresses on the same first 3 subsets of IPA, SN & DG for the PLC & HMI, PC is able to talk to both on the switch... Am I making a mistake on the tags? Tags are the same in CCW as on the HMI, did export/import & manual, checked the data type, etc. still no luck. Does someone have a sample of a ladder rung, variable table for tag(s) & HMI tag(s) with some configuration settings they would be willing to share for a Micro820 or similar? If I can get them talking I can take care of the rest of what I need to but I'm stumped at the moment.

Bear with me as I am not in front of any gear at the moment.
Are the tags from the PLC project global tags or local tags? If I remember correctly, the tags must be global for the C-More to access them. I don’t believe the panel can access local tags.
Can you attach a notepad document that has your tag name database pasted into it? That way, this crazy bunch of programmers in here can get some eyes on it.

Boom, solved!
The issue was two-fold, addresses needed to be in global variables & I was changing the address to the PLC, instead of the tag name.
Thanks a million!
