AFTER USING MODBUS SERVER NODE MY NODE-RED IS NOT WORKING.
PL GUIDE TO SOLVE.
You should post this screen shot on the GitHub repo as an issue. The node is not correctly handling socket issues.
To get back in to node-red, add command line parameter
--safe when you launch it.
This will start node red without starting flows. That will allow you to edit and remove the node which is crashing node-red.
thank you for your reply.
As @Steve-Mcl says there is a bug in the node as it should catch that problem and not crash node-red. As to why it is happening, do you have a choice over the port number you are using ( 502)? Regular users cannot normally listen to port numbers below 1024 which may be the root of the problem. If you can change it to a higher number then perhaps you can avoid the problem.
yes its worked.
Please can you also open an issue on the nodes github page as @Steve-Mcl suggested.
A node should not cause Node-RED to crash and it is something the author should fix.
You can follow a link to the nodes github page by following the link from the nodes page on flows.nodered.org
i will open an issue on github.
