I’ve been at this for days trying to read and write to a specific address on an ADAM 6022, address 40011. I have been talking with a tech support of Advantech and he says that you can read and write to that address. He says it is a holding register with an unsigned integer, but he also says it is a 12 bit address. There are other addresses on this device that I can read and write to and those addresses I just put in the address with no identifiers. Ex. OPC Item Path [Device name]41138.
I can however, read from the address 40011 using HR11, HRUS11, IR11, and IRUS11. But I can not write to it. I get the error message
“Error writing to MV Value.Value:
The access level does not allow writing to the
The Access rights are set to Read/Write.
To add further notes I can read and write to that address using third party software like modscan. So it is an issue with ignition in some way or form. The only thing I can think of is the 12-bit address.
Is there anyway I can write to this address using ignition?
