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, ...

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 ...

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 previous issues, we have discussed troubleshooting input modules. In the examples, the output modules checked out OK. But what if they don't? As with input modules, output modules can be digital or ...
