CtrlX: How to Intsall Palette?

Hi there,
I'm a bit new to Node-RED, Using it through a Bosch Rexroth PLC and i'm trying to learn and explore options.
So today to communicate and run some Commands to a Camera we use, i have to use TelNet, now i have understood there is a Palette with nodes for that for Node-RED but everytime i try to install it i get errors. I've tracked this down to Node-RED not having acess to the internet, but i do not how to allow it to go Online on a Bosch Rexroth CtrlX PLC.

My main Questions for the community are:

  • Can I install it manually on a CtrlX Device? If so, then how?

  • How do i enable either my CtrlX Device and/or Node-RED on it to go online when i am connected through my PC with Ethernet Cable?

  • Are there any other options with the main nodes i already have to send TelNet Commands through Node-RED or if i can send a Command directly to an open TelNet software for example on another PC that is connected and then it will run the command that is sent automatically?

I know nothing about the device, but searching online for
access internet from Bosch Rexroth CtrlX PLC
brings up a number of hits which might help you.
