We are having trouble getting Ignition to write to User Defined Data type instances in Controllogix. Everytime we write to a Clx user defined type tag, we get an unknown error.
All other writes to the standard data types and AOI instances seem to work without a problem. This only appears to apply to User defined data types.
I have tried dragging the tag from the OPC Browser to tags to create the tag. I have tried changing the scan rate. I have tried adjusting the timeout settings in the device driver.
Edit: in the Console, I’m getting
[[default]B1/ESTOP] Error writing to OPC address [[Ignition OPC-UA Server]ns=1;s=[PLC]Global.B1.ESTOP]. Result code: [Bad] Bad; unspecified.
In wireshark the CIP info is:
Embedded service error, Path segment error
