Hello PLCnext team,
Is it possible to upgrade the node-red version on the EPC 1502? And if this is possible where can I update the node-red version? I am currently at version 1.3.5
I was also wondering where on the PLC I am able to find the install location of node-red?
To be more specific:
I would like to install a node-module/library in the PLCnext node-red. But to install the nodes I need to have version 2 of node-red or higher.
An other option would be to install a downgraded version of the node-module. But to do so I probably need to use npm install command in the terminal. But when I tried to SSH on the PLC it did not recognize npm. But npm does work if I look into the logs of node-red.
Hello Jan,
sorry the pre-installed Node-RED can’t be upgraded right now.
This will be possible in the next firmware version. If you need a newer version of Node-RED right now, you could install another instance of Node-RED from our PLCnext Store (PLCnext Store | NodeRED for PLCnext x86)
If you want to install an older node-version via npm into Node-RED:
As far as I know, the palette manager in Node-RED is only able to install the newest version of a node.
But you should be able to do a little workaround via a SSH Shell (PuTTy):

1. Connect to your EPC via „Putty/SSH“ and log in with admin credentials and type in following commands:
2. export PATH=/opt/plcnext/edge/nodejs/bin/:$Path
3. cd /opt/plcnext/edge/nodejs/lib
4. npm install [package-name]@[version-number]
5. Reboot your device, the new package should be visible in Node-RED
