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 ...

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, ...

An overview of the hardware and software components of PLCs and their programming languages. A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and ...

The PIC operates by sensing a low-to-high change on the RB0 input. This change causes a wake-up interrupt in the PIC. After some suitable debounce interval (50 msec), the PIC selects A/D channel 0, 1, ...

Company Announcement - IDEC announces a new model in its FT1A Touch micro programmable controller series of combo HMI+PLC units, the FT1A Touch 14 I/O. New features make the FT1A Touch 14 I/O suitable ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

Beckhoff Automation has extended its range of IP 67 I/O modules with the newEP4374 EtherCAT Box. This flexible, moisture and dust-resistant I/O devicecombines two analog inputs and two analog outputs ...

In industrial applications, controlling relays, servos, solenoids, and the like isn’t just a matter of wiring in an Arduino and plugging in some code. No, for reliable operation you’ll need a PLC – a ...
