##	Name	Description
01	SimpleIOReadWrite	Control the IO of the controller in a real-time cpp program
02	NoEngineerHelloWorld	Create a cpp real-time program that uses logging and deploy it to the controller withouth using PLCNext Engineer
03	RestCommunication	Uses a cpp real-time program to read and write IO from the controller and also makes it available to the rest interface, through which it also receives commands to set the output.
04	MqttCommunication	Read the IO from the PLCNext starter kit, sends it over MQTT to a broker using the IIot Library by PlcNext.
05	GrpcRemoteCommunication	How to read and write controller data remotely using grpc. An example using the command-line tool grpcurl and python is provided.
06	GrpcLocalCommunication	How to read and write controller data localy using grpc running on python on the controller itself. Employs a podman container to use python.
07	OpcUaCommunication	Read controller data remotely by connecting to the OPC UA server of the controller. An example using the program UaExpert is provided.
08	ToasterOven	An extensive example project utilizing ladder logic, cpp real-time programs, the rest interface, and remote grpc.

How to install all dependencies and tools necessary to work with plcnext. All the steps are valid for ubuntu linux.

Download the right version from here

Run the executable:

/bin/sh PLCnext_Toolchain_2024.6.sh

Press q and then y to accept the license.

Move the folder to /opt and link the file:

sudo ln -sf /opt/PLCnext_Toolchain/plcncli /usr/bin/plcncli

Test if plcncli is accessible:

plcncli --version

Download axcf2152 2025.0.3 sdk from here (Pick the right version and operating system under Software)

Navigate to where the download got saved and run:

chmod a+x axcf2152-linux_sdk-2025.0.3-25.0.3.99.sh
sudo mkdir -p 
sudo mkdir /opt/pxc/2025.0 -p
sudo chown $USER:$USER /opt/pxc/ -R

Install the sdk with plcncli:

plcncli install sdk --path axcf2152-linux_sdk-2025.0.3-25.0.3.99.sh -d /opt/pxc/2025.0

When plugging the controller directly into the computer via ethernet while using Wifi for internet:

Find Device Name of Ethernet:

nmcli device

Create connection:

nmcli con add con-name "plc-con" ifname <device name> type ethernet

Configure connection:

nmcli con modify plc-con ipv6.method disabled
nmcli con modify plc-con ipv4.method shared ipv4.addresses 192.168.1.1/24

Enable and test connection:

nmcli con up plc-con
ping 192.168.1.10 (address of controller)
ping github.com (Check if internet works)
