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, ...

Acromag has introduced the XMC-ZU series, a configurable XMC module based on the AMD Zynq UltraScale+ MPSoC. The device ...

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 ...

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 ...

The new CPUs feature two analog inputs and two outputs with ranges of voltage up to 5VDC or current up to 20mA. The modules include two built-in RS-232 communication ports and one RS-485 port, as well ...

A long list of industrial-control modules manufactured by Schneider Electric and used to control operations at various industrial facilities contain multiple weaknesses and vulnerabilities that could ...

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 ...
