Ethernet-ip protoccol

Hi Everbody;
I am trying to read tags from Allen Bradley Micro 850 PLC with node-red-contrib-cip-ethernet-ip node
but I am taking this error : Error connecting to PLC: Error: TIMEOUT occurred while reading Controller Props. How Can I solve this problem.

It's a bug.

But perhaps you can work with the author to fix the bug.

How Can I get the author code?

First of all Thank you for answer.

RamazanAslan38, here are a couple of steps you might take if you've not already.

  1. Verify you can ping the PLC
  2. Verify you have visibility to port tcp 44818, you may also need to open 2222 as well.
  3. Verify the slot number for the PLC is correct.
  4. Verify the tag name and scope are correct.

I'm currently using this node to communicate with several AB PLC's from version 13 to 21 but not the Micro 850. . Let me know if you have any further questions or need additional help.
