I am experiencing a “Bad” Value when attempting to read two 16bit modbus register from a local device and cannot seem to troubleshoot the issue with Ignition OPC-UA.
I’ve done the same in KEPWARE and was successful, so I’m thinking I’m configuring the Ignition side wrongly somewhere and am looking for some advice or articles to help.
my address configuration:
V_ 0 10 TRUE 0 HoldingRegisterFloat 1
Device Manual mentions “These registers are 16 bits each and are organized as shown below. All of the values are reported as 32-bit IEEE standard 754 floating point format.
This uses 2 sequential registers, least significant 16 bits first.”
