Hello everyone,
I'm currently having problems connecting Node-RED to my Beckhoff PLC running TwinCAT 3.
I have already contacted Beckhoff support, but unfortunately they were not able to help me solve the issue. Therefore, I'm hoping someone here might have an idea.
When I try to establish the connection from Node-RED to TwinCAT, I receive multiple error messages (see the attached screenshots). The connection cannot be established.
My setup:
- PLC: Beckhoff with TwinCAT 3
- Node-RED running on a separate PC
- ADS communication
I have attached:
- Screenshots of the error messages from Node-RED.
- A screenshot of the TwinCAT route/IP configuration on the Beckhoff controller.
Has anyone experienced similar issues or knows what could be causing this? Is there anything specific I should check regarding the AMS Net IDs, ADS routes, firewall settings, or Node-RED configuration?
Any suggestions would be greatly appreciated.
Thank you!
