Hello! I have been trying to learn how to grab data from a scale machine on site that supports Modbus TCP. But have been having some issues.
Question: Inside the Ignition Designer, I'm making a new OPC Tag and setting up the path as [Yamato]HR2068 but the value being returned is 0. Am I not filling the path out correctly?
The serial number should return WG140727.
MODBUS_GC48108H0004_EN.pdf (680.2 KB)
Try an address like this for serial number:
[Yamato]HRS2068:12
See Modbus Addressing | Ignition User Manual for the address syntax.
edit: you also probably want to turn on zero-based addressing, as they are listing addresses from 0 in the docs.
Yeah I have the page pulled up, but nothing is working that I can find so I figured I was missing something.
I tried the HR2068:12 and im still getting 0.
That's not the same path I posted; you're missing the 'S' in 'HRS'.
Good eyes, I updated it but not getting anything now
Get a Wireshark capture and we can see if it's just the device returning no data in those registers.
I will do that, thanks for the help!
Probably need 1.HRS2068:12.
