I'm trying to write data to an Omnron NX1P2 but I'm getting this error

I managed to connect and read the tag using what is commented in here #10

This is my tag configuration

any help would be appreciate.

Hi,

I have communication on two Omron PLCs (NX1P2-9B24 and 1040).

I had to make this library modification:

The fix is 2 lines modification:

comment the line 125 on this file node_modules/ethernet-ip/src/controller/index.js

modify ethernet-ip\src\enip\cip\unconnected-send\index.js search for this const build = (message_request, path, timeout =
2000) and change the time out from 2000 to 5056

After this restart Node-red and you should be able to connect and read form the PLC.
