[232] when i run the flow, it is connected to the plc but when i try to read data, timeout occur. Anyone have encounter this issue? Your help is highly appreciated..

This issue was resolved outside of the forum. For anyone reading, the issue was @DonCube running node-red V2.x + nodejs V10 Both node-red v2.x and node-red-contrib-omron-fins require nodejs V12+

It is likely the FINS parameters are incorrect on the config node or your PLC or the PLC routing table. Did you follow the info on the readme ? Also, read through the closed issues on github If you still have an issue, let me know your PLC settings (IP address+subnet mask, TCP or UDP, port number,…

[image] I want to read the D03552, 32bit and this error occur

32bit is 2 WORDs. You are only asking for 1 WORD Did you change connection protocol to UDP?

For 32bit numbers, set the output to Buffer & use buffer parser to convert to 32bit. I'm sure there is a demo in the import examples (CTRL+I)

Lastly, what are the node number dials on the front of the PLC set to? Show me a photo of the 2 node number dials.

[image] i got this error when i change to udp, what do i need to set in the PLC side? i use CX one programmer

Is your version of fins node up to date? I seem to remember a bug. Also, what version of nodejs is on your node-red machine?

You have protocol set incorrectly. Should be UDP
