This is a little quickstart on how to use PLCnext Technology with IO-Link devices.
When implementing IO-Link (IEC 61131-9) for the first time there are some "have to know" things.
I hope this quickstart helps everyone to get on the right track.
To be able to follow this blog, you must have alreday installe the OPC-UA inside Node-Red.
Then, it will be possible to send a mail, with a command from the PLC (xSend) including a variable message (strText).
Here are the 2 variables of the AXC F 2152 which will be used and accessible by OPC UA :
OPC option must be checked.
Here is a method to create and test a simple MQTT broker on the AXC F 2152 / Node-Red.
Goto the Node-Red menu (the 3 lines, at the right of the screen) and select ‘Manage Palette’.
Go to the Install tab, and type ‘mqtt’ in the ‘search modules’ line
There, select ‘node-red-contrib-mqtt-broker’ and clic on ‘install’.
The AXC F 2152 has 512 Mb RAM. Of this the OS is using a part of it but there is still a lot which is not used. This free space could be used for a RAM drive. Unlike the SD-Card the RAM drive has no limitations in reading and writing. Therefore it could be very useful for tasks which have a lot of reading and writing, e.g. a Datalogger. The downside of the RAM drive is that everything on it is gone after a restart/reboot of the controller. So it would be a good idea to have a backup solution for the data.
Hello PLCnext Community,
you probably already have seen awesome things within the last publication, like Node-RED, the package manager and PROFICLOUD.
All right, but all these cool IoT applications have a common need, that is right, they need to be connected to the Internet in order to function. Well, our colleague Josh Krug put together this great documentation on how to configure the AXC F 2152 for an Internet connection.

Python is a powerful language with plenty of applications for Industrie 4.0, including Machine Learning and Cloud connectivity, so it’s a natural fit for applications that use PLCnext Technology. In this episode of Automation Maker, we look at how to install Python and PIP on a PLCnext Control. Helpful links: just click the "Read more..." link below the video. |
This demonstration was our highlight in the Phoenix Contact IoT zone during Automation India Expo 2018:
In the previous months I prepared the PLCnext Technology exhibition wall for the showroom in our Polish Phoenix Contact subsidiary and I would like to show it to the community.
I made the applications with as many technologies as I was able to, that's why I used MQTT, OPC UA, Node-RED, Google Home etc.
These four example tasks can be demonstrated:
