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, ...
Almost exactly four years ago, we came across a really neat module for sale on SeeedStudios. It was a $5 WiFi chip, able to connect your microcontroller project to the Internet with just a handful of ...
Editor's Note: Linux remains an attractive option for embedded systems developers. In fact, industry surveys such as the Embedded Market Study by UBM (EDN's parent company) consistently show interest ...
Size and power often seem like opposite sides of a coin. When you reduce size – one of the ever-pressing goals in our industry – you inevitably reduce power. But does that have to be the case? By ...
In the first part of this blog, we had a look at how energy-efficient high-power modules contribute to the decarbonization of railway transportation. This part will focus on the future of traction: ...
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 ...
