PLC Technology and Application Tips

Although the North American market for automation and controls has seen nowhere near the growth it did 15-20 years ago, programmable logic controllers (PLCs) are still the preferred controller choice for industrial applications. What has changed for PLCs are the expectations and desired functionality of their specifiers and users. In this edition of PLC Speaking,…

2005 DARPA Grand Challenge

“After preliminary testing of our vehicle, and the subsequent breaking of a couple of welds, we’ve come to a few conclusions. First, our steering actuator has a lot more power than we really need! Second, we never should have attempted to test the steering system without the use of the encoder feedback. And third, we…

A User's Guide to Configuring Serial Ports for DirectLOGIC PLCs: Part Two

In the previous issue of Automation Notebook, Winter 2005 Issue 3, we discussed the communications capabilities of Port 2 on the DL06, DL250-1 and DL260 DirectLOGIC CPUs. We covered networking, wiring diagrams and protocols. In this issue we will discuss how to configure the communication port using DirectSOFT programming software while connected to the CPU….

PLCs Evolving Toward Motion Control

In our fast paced and economically stressed industrial world, flexibility is becoming a higher priority for those who are specifying automation systems. Users need multi-functional control, simple connectivity and easy access to process data, all wrapped up in a nice neat package. Today’s Programmable Logic Controllers (PLCs) have to be much more than the relay logic…

PLC, PC, or Custom - Which Control Choice Is Right For You?

Choices and change are the only constants in control system technologies today. Current industrial controller products can no longer be classified by the internal design architecture they possess. More often than not, any type of modern controller uses some portion of Commercial Off The Shelf (COTS) technology in its CPU, operating system, memory, or data…
