Debug information in autostart mode - NodeRED

Mronia Posts: 24 Rating: (0)	Dear All, I am using IOT2040 with PLC Simatic1500. I have NodeRED in autostart mode. I check if the NodeRED is running using command: ps -aux \| grep node I have removed the current flow to start with empty one using commands: cd /home/root/.node-red rm flows_iot2000.json After rebooting I am able to open NodeRED editor in the browser however after adding one S7-in node configured with the PLC and one debug node, the NodeRED crashes after deploying. I would like to check what is wrong but in the autostart mode I don't have any information displayed in putty like I have while running manually. Is there a way to enable displaying current information from NodeRED in autostart mode?

There is a lot of entries about that already, e.g here. You need to install the version 2.1.1 of the node with npm install -g node-red-contrib-s7@2.1.1 Best regards!
