Hardware - PLCnext I/O

PLCnext I/O Introduction

CDP Studio allows you to build and run control systems on the PLCnext controllers from Phoenix Contact and use the attached I/O modules. The PLCnext is pre-integrated in CDP Studio and the different I/O modules are available by simple drag and drop; no coding is required to use the PLCnext I/O modules.

Prerequisites:

Note:

The PLCnext controller must be set up with a 'root' user to be able to access the Axio bus. Follow the steps in Installation and Removal to do this.
The device must be 'Paired' in the Devices table. When pairing with the PLCnext target Device, it is important that you use 'root' as the username. See the Deployment Manual for more information.
The PLCnext ARMv7 32-bit Toolkit must be chosen for the target device (this is automatically selected when you pair).
Installation, as outlined below, must be performed.

Installation and Removal

The PLCnext Axioline AXC F 2152 controller has a default IP address set to 192.168.1.10. The default user is 'admin' and the default password is printed on the side of the controller. Refer to the PLCnext documentation on how to change the IP address of the controller.

Installation

Log into the device with the admin user by using an ssh client:
```
ssh admin@<plcnext IP-address>
```
Set up the root user using the following command:
```
sudo passwd root
```
You will first be asked the password for the admin account to allow running the passwd command, and then asked to set the password to use with the root account (this will be asked twice). Make sure to select a strong password to secure the device against unauthorized access.
Become the root user by typing
```
su
```
Type the root password set in the previous step when prompted.

Disable unneeded services to reduce resource usage, and enable root login via ssh:

systemctl disable codemeter.service
systemctl disable plcnext.service
sed -i 's|^#\?PermitRootLogin.*|PermitRootLogin yes|' /etc/ssh/sshd_config

Reboot the controller by typing
```
reboot
```
After the controller has rebooted, Pair the Device with CDP Studio

Removal

To undo the above changes, log in to the controller using an ssh client, and type:

systemctl enable codemeter.service
systemctl enable plcnext.service
sed -i 's|^PermitRootLogin.*|#PermitRootLogin prohibit-password|' /etc/ssh/sshd_config
sudo passwd -l root
reboot

This will re-enable the default PLCnext services, disable root SSH login, lock the root account and reboot the controller.
