Unable to write data to AB control logix

[TT_13245152]

Hello,

I've created connection with my Rockwell PLC. I'm able to read all the data, However I'm unable to write anything.

CS433164 - OPC DA Client driver Async Write 2.0 failed with Callback item error: "0xC0040006" in PTC Kepware Products

Tags in PLC are R/W. What can be the issue?

Hi,

Kindly verify if you got the write permission, permission to make changes?

-Thank You

Do you mean this? Or some settings in PLC?

In PLC Read/Write is set
