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 ...

This high speed digital output module TI Design for programmable logic controllers (PLCs) illustrates the design of low-cost, simple high speed single-ended digital output module using standard low ...

Narrow-band low-frequency power-line communications (NB LF PLC) is a hot topic these days. Engineers creating PLC modems must consider which PLC standard (PRIME, G3, S-FSK) will be used and which ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

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

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, ...
