Making the move to PC-based motion control
. In this application, the first three icons configure the velocity and acceleration for the two axes. The next three icons move the axis to the correct position. The remaining icons create the half circle and blend it with the large circle. Not too long ago, programmable logic controllers (PLCs

The Evolution and Elements of Robust PC-Based Control
To understand the nature of PC-based control, it is useful to look first at its ancestry. For decades, industrial control was executed through a complex array of mechanical relay devices. In the 1960s, however, these devices gave way to programmable logic controllers - or PLCs. While not marketed

Use of a PC-Based Digitizer in an Ultrasonic Flaw-Detection System
path. A programmable. Delay Gate is used to create a TTL pulse that occurs 700 µs after the ultrasonic excitation. This pulse is used to trigger the digitizer. The ultrasonic echo trains of interest then occur. over a period of up to 100 µs. The engineer would like to write a controlling application

Chameleon of control: The ever-changing PLC
with an Omron CQM1 PLC and an Omron IDM drive. An Omron CS1 PLC mounted in a cabinet controls machines in a foodprocessing plant. After more than a decade of articles touting the benefits of PC-based control over programmable controllers and predictions of the PLC's demise, this much is clear: both

Industrial Ethernet made practical
Divide and conquer is the strategy for devising factory Ethernets that work reliably. One example of a device now available for use on industrial Ethernets is the Compumotor 6K Controller. The multiaxis motion controller has a programmable IP address to allow use of several on the same Ethernet
