Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range ...

The E-1048-700 solid-state remote power controller debuts as the market's first such controller to protect programmable logic controllers (PLCs) from overloads and shorts while amplifying PLC output ...

I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

Industrial manufacturers must often attempt to forecast equipment requirements when installing a new system or building a new factory. Projecting communication ...

In our previous issue, we said a digital output module could be tested by using the PLC logic to force the output on and off then and observing the module’s response. If the module doesn't respond, ...
