Programming and Setup Considerations for VFDs with Integrated PLCs
Control capability built-in to VFDs are moving machine intelligence to the edge. Jeff Payne, Product Manager for AutomationDirect, wrote an article for the March 2019 issue of Design World, titled VFDs with integrated PLCs for motion and machine controls: Programming and setup considerations. Payne explains how AC drives can be controlled by either an external…
PLCs are typically programmed with PC-based software, and selecting the right platform is critical to project success and ongoing operations. Bill Dehner, technical marketing engineer at AutomationDirect, wrote an article for the February 2019 issue of NASA Tech Briefs titled Selecting a Software Programming Platform, here’s a summary. Dehner says software development and testing is…

Basic Sensors - PLC Fundamentals
For a PLC to monitor and in turn control its application variables, there must be a way for it to sense its surroundings. In today’s industrial realm, there are a huge variety of electrical sensors that provide the input data (position, distance, level, flow, etc.) that control systems need. These basic sensors can be broken…
There are several ways to perform IIoT remote monitoring of PLCs and HMIs, with VPN connections providing the highest level of security. Bill Dehner, Technical Marketing Engineer at AutomationDirect, wrote an article for the Jan/Feb 2019 issue of InTech magazine titled IIoT Remote Monitoring. A summary is below, please click here for the full text….
With PLC control, it’s important to understand the sequence of operations for the CPU. Some may think when an output is set to ON in the ladder code, that this output change is immediately reflected in the output card. Or that when an input is activated, the CPU instantly sees it. While it may seem…
Two of the most important fundamentals to understand when it comes to sensors is sinking and sourcing circuits. To properly wire your control device, you need to first know whether the sensor you are using is switching the positive or negative connection. For AC (alternating current) sensors, this is not an issue since AC power…

Honing in on Machine Automation
The automation and electrical system on a large, 82-year-old cylinder honing machine was replaced with a variety of AutomationDirect hardware to improve cycle time, safety and quality. Andrew Marks, Maintenance Foreman and Master Electrician at Exline Leasing Inc., wrote an article for the January 2019 issue of Control Design magazine, titled Honing in on Machine…
For a better understanding of PLCs, let’s take a closer look at one of the fundamentals of automated control – logic circuits. Electrical components can be hardwired in a way to allow certain decisions to be made electrically. They can provide physical “If, then” statements that systems can use in their decision making. “If this…
