It's time to get a little more specific with what the PLC CPU controls: PLC I/O! This article will discuss discrete I/O, analog I/O and briefly introduce industrial communications protocols. We talked ...

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 ...

At the heart of many industrial automation and process-control systems, programmable logic controllers (PLCs) monitor and control complex system variables. Employing multiple sensors and actuators, ...

In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...

PLC evaluation board applications for industrial process-controlsystems are diverse, ranging from simple traffic control to complexelectrical power grids, from environmental control systems ...

. These modules provide higher resolution for more precision in measurement and control applications. 8-channel input modules are available with input ranges of 0-20/4-20 mA and 0-5 V or 0-10 V. Four ...

AutomationDirect's Productivity2000 programmable logic controller provides two independent single-ended 5-24 VDC inputs that accept up to 100kHz of pulse/direction and quadrature signals. The ...

Recently I became interested in PLC programming. I'm not planning on working in this field on building a career, just want to play with a bit. I've some background in software development and ...
