Seal-In Ladder Logic vs. Latching/Unlatching PLC Commands

An age-old debate in PLC programming: investigating the uses and caveats of latching software commands versus seal-in ladder logic for industrial control applications.


Licensing Your New Software in the Modern Industrial Landscape

Licensing Your New Software in the Modern Industrial Landscape

As commercial and industrial software migrates to ‘cloud-based’ and ‘subscription’ models, what does it mean? How does it affect the usability and security of critical parts of control infrastructure?


Python Tutorial Part 7 | Conditional Flow: If Statements

Python Tutorial Part 7 | Conditional Flow: If Statements

The next part of our Python learning journey will touch upon control flow, critical to implementing logic in programs. The concept is broad and the first topic to cover will be if/elif statements.


The Beginner’s Guide to Automation: Maintaining Your System

The Beginner’s Guide to Automation: Maintaining Your System

It's important to keep your system up and running without regular intervention. While every system requires maintenance, never overlook the critical importance of tools and training for the operators.


Tutorial: Analog Signals with Phoenix Contact’s PLCnext Platform

Tutorial: Analog Signals with Phoenix Contact’s PLCnext Platform

Python Tutorial Part 6 | Data Structures: Sets

Python Tutorial Part 6 | Data Structures: Sets

Wrapping up the data structures portion of our journey are sets. This is the least frequently used data structure, but don’t write off the set just yet. Its efficiency and simplicity may provide value in manufacturing data processing.


Networking Woes | How and Why To Change the IP Address of My Computer?

Networking Woes | How and Why To Change the IP Address of My Computer?

Every method of connecting to an industrial device—USB, serial, or Ethernet—poses challenges. For Ethernet, we often must adjust the IP address of our PC, not only the device itself.


Python Tutorial Part 5 | Data Structures: Tuples

Python Tutorial Part 5 | Data Structures: Tuples

As we approach the conclusion of Python data structures, we’ll examine the tuple. Used less frequently than lists and dictionaries, tuples do serve some handy use cases where immutability is a critical requirement.


The Beginner’s Guide to Automation: Testing, Commissioning, and Debugging

The Beginner’s Guide to Automation: Testing, Commissioning, and Debugging

When setting up a system for the first time, the process can seem complex and daunting. However, there are tools available to make the job much easier before commissioning.

Python Tutorial Part 4 | Data Structures: Dictionaries

Python Tutorial Part 4 | Data Structures: Dictionaries

Both lists and dictionaries can retain structured data in Python. The dictionary is unique in that it stores individual entries with human-readable logical names rather than index numbers.


Logic at the Sensor Level: Can it Simplify Automation?

Logic at the Sensor Level: Can it Simplify Automation?

Sensor networks with built-in logic functions can save cost and program execution speed, but what are those various logic functions, and when might they be preferred over normal PLC ladder logic?


The Beginner’s Guide to Automation: Adding Control to the System

The Beginner’s Guide to Automation: Adding Control to the System

Every automated cell requires a ‘brain’ in order to achieve the required tasks. How do you determine the necessary I/O, communication protocols, and processor necessary for controlling your system?
