Connect innext controller to linux12/31/2022 ![]() This unique program allows users to create applications across a spectrum of languages. PLCnext contains a modular software platform called PLCnext Engineer. It runs Yocto Project ®, a Linux Debian OS that “provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations, and best practices that can be used to create tailored Linux images for embedded and IOT devices.” Inspired by the Raspberry Pi, Phoenix Contact’s engineers created an inclusive platform that supports traditional IEC 61131-3 PLC languages like Ladder Diagram (LD) alongside high-level IT languages like Java, C++, and Python. Software, on the other hand, is what sets PLCnext apart from other PLCs. It uses an ARMv7 support 32-bit processor, which reduces cost, power consumption, and heat dissipation. Just like with any other PLC, the manufacturer’s goal was to create the fastest system possible with the least amount of hardware. At its heart, it is a ruggedized computer designed to withstand extreme conditions and provide high reliability. PLCnext bridges the gap between these two worlds. This brings numerous benefits, but it also creates new problems. So-called “smart devices” in the IIoT still serve their operational functions, but, as they communicate with each other and connect to the internet, they also have an IT component. Today’s industries are seeing a seismic shift: IT/OT convergence into the Industrial Internet of Things (IIoT). The IP address to use is the one given in Ubuntu when you run ifconfig.PLCnext was designed by Phoenix Contact because the company saw the possibility of connecting different worlds, languages, and generations. Or you can check in VirtualBox preferences (not the VM Settings, but the VirtualBox preferences) under network, check the IP address of the Host-only ethernet adpater (click on the Edit button of this interface). This IP address is the same one as for the VirtualBox Host-only network, you can check the IP in Windows networking center by clicking on the interface and displaying its status/details. Then you click on the Port Forwarding button and create a new rule, you name it "telnet" (or whatever you prefer), protocol should be "TCP", leave the fields Host and Guest IP empty, but set the Host and Guest Port to 23.Ĭheck the external IP address of the VM to access it. ![]() Select NAT and unflod the advanced settings of the NAT interface in VirtualBox settings. Make sure you have no firewall on Ubuntu: sudo iptables -L should give you no rules. Your Windows host is connected to a networkĪnd select the Windows network interface that is configured under Windows to have network access. You have 3 solutions depending on your environment:Ī. So here are in one answer a summary of my comments. : 10.125.31.1Įthernet adapter VirtualBox Host-Only Network: Windows IP Configuration Ethernet adapter Local Area Connection:Ĭonnection-specific DNS Suffix.

I have also performed the open ports scan and it seems ok: $ sudo nmap -p 20-2550 localhost ![]() Telnet: Unable to connect to remote host: Connection timed outĪlso I'd like to mention that I could easily ping this machine (both ways): # ping 10.125.31.176 Telnet: connect to address 10.125.31.176: Connection timed out Then I tried to access this system using telnet from another machine but unfortunately the connection become timed out: # telnet 10.125.31.176 In order to do that I've performed the following steps: I'd like to access this Ubuntu machine using ssh or telnet. I have a VirtualBox running an Ubuntu OS.
