And, the ability to monitor PLC logic in ladder diagram format also made troubleshooting easier for those already familiar with relay-based control systems. Although there are many higher-level ...

Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...

It may help to think of this control relay C1 as the coil of the relay when used as an output on the right-side of the ladder diagram, and as one of the associated contacts of that coil when used on ...

Machine Design talks to a panel of experts about where ladder logic fits in the factory of tomorrow.

The UTAdvanced Hybrid Controller takes the superior PID control that Yokogawa is known for and combines it with a new, standard, no cost, embedded ladder sequence control. The new feature supports 84 ...

Back in the 70s, industrial control was done with either relays and ladder logic or new programmable logic controllers. These devices turned switches on and off, moved stuff around a factory, and ...
