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, ...

Designed for use with the vendor’s SNAP Ethernet I/O systems, the SNAP-ODC-32-SNK and SNAP-ODC-32-SRC 32-channel digital output modules offer new levels of density for applications with high digital ...

Safety-relevant output modules as well as a logic module with expanded functional scope have been added to modules already available. Fourteen different safety-relevant function modules, from a simple ...

Adani Solar, Jakson, Premier Energies, Vikram Solar, Waaree and other Indian manufacturers are showcasing their high-output modules ranging from 500 W to over 600 W at this year’s Renewable Energy ...

Two analog-output modules, the BusWorks 972EN and 973EN, convert Ethernet Modbus/TCP instructions from network controllers to DC voltage or current outputs for driving as many as six measurement or ...

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 ...

Research by the Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) has found a negative trend emerging between performance data from PV module manufacturers and the institute’s ...

Two trends in electronics show no signs of abating: The shift to portable and mobile products across multiple applications; and packing more and more features into each successive generation of ...

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.
