In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...
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 ...
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 ...
A human machine interface (HMI) connected to a separate programmable logic controller (PLC) is the standard system for machine automation. However, combining PLC processing and HMI monitoring and ...
This multi-channel analog output module TI Design with multiplexed single channel digital to analog converter (DAC) for programmable logic controllers (PLC) illustrates the design of low-cost, ...
Easing the burden of supporting multiple regions with one device, Texas Instruments (TI) announced a new power line communication (PLC) modem platform that supports the G3, PRIME and IEEE-1901.2 ...
A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...
