PLC and HMISubscribe
Today we are far removed from this, PLC’s are the main part of control systems worldwide. They integrate with field devices, perform motion control functions and can either be used for stand-alone single machine functions or part of a larger distributed control system within a facility. Modern PLC’s are extremely robust and versatile, all the major brands invest heavily in continued development of their range’s, adding more functionality, speed and processing power, together with add-ons such as expanded I/O and control module options.
HMI's present system data to the operator, give visuals of the industrial operation and link to SCADA systems and databases to provide key diagnostic data such as, trending, scheduled maintenance and real time visibility of the system. Within in this hub you can view and post all things PLC and HMI.

Hi there, we're unable to find anything related to A5E32619040-AB on the Siemens database. Could you please tell us the model of the HMI and possibly take a picture of the part number on the product itself?...
Thanks for the hint. The video is added and should make it even easier to start with miCon-L.
I have shown over a few articles how to install and use the Phoenix Contact 2153 starter kit. But not how to install and license the Software needed for IEC61131-3 programming, well now I do.
This is part three of three videos, now we will configure Node-Red on a Raspberry PI 3B+ with OPC UA modules leveraging Secure and Encrypted communications to the PLCnext 2152.
This video will cover how to configure the parameters and mapping to physical IO prior to use with OPCUA and confirm remote availability using PCWorx Engineer, the design tool from Phoenix Contact.
Before you can really get started with the PLCnext starter kit or even just the AXC F 2152, there are a few things that need to be initialized or updated, like updating the firmware from 1.0.0 to 18.104.22.168 and setting the Time Zone, Date and Time.
A three-part post to show how to get up and running with Open Platform Communications, Unified Architecture (OPC UA ). This is Part 1: Setting up the Environment.
You asked for it. Here it is, an IEC 61131 compliant PLC controller with Digital and Analog IO modules which is fully IEC 61131-2 and -3 compliant, providing graphical Ladder and Functional Block as well as Structured Text programming environments.
