When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

When learning ladder logic, I was told that some new PLC systems were moving to scripted programming languages. My instructor assured us that we would not need to know anything other than ladder logic ...

Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...

Yokogawa Corporation of America is proud to announce a new addition to their temperature controller product line, the UTAdvanced™ Hybrid Controller. The UTAdvanced Hybrid Controller takes the superior ...

Two new controllers have joined the Jazz 2 Series, the JZ20-R16 and JZ20-R10. The controllers feature 48K (virtual) ladder-logic memory and a built-in mini USB programming port. The controllers can ...

While acknowledging the potential benefits of Python and C++, engineers caution against their indiscriminate use, particularly if there are existing IEC 61131 functions available. The debate between ...

PLC Counters and Timers provides an overview of the functions of counter and timer instructions in a PLC ladder logic program. Counter and timer instructions are internal features of a program that ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...
