Automating Hazardous Gas Delivery
When a highly flammable, toxic and corrosive gas delivery system for semiconductor production tools became unreliable, Headway Technologies contracted with system integrator KCC Software for the needed upgrades. KCC Software’s experience and expertise led to the successful replacement of a failing automation system with a new automatic gas control (AGC) system.
What may seem to be a simple task of selecting a soft starter for your motor may be a more demanding task than first meets the eye. “I just need to know the HP and Voltage to pick the correct one, isn’t that right?”
Sensors and transmitters convert a variety of physical properties into discrete and analog signals for use by automation controllers. AutomationDirect offers an assortment of these devices for use in the design and operation of machines and processes to create reliable, robust and consistent automation. It may only take a small change in a physical property…
Locking tongue operated safety interlock switches provide a tamper-resistant actuator mechanism for sliding or lift-off machine guards, as well as a method for locking the guards in place. They also provide robust position interlock detection and locking for moving guards. Safety switches offer positively operated switching contacts for maximum reliability.

Ethernet Dos and Don’ts
With the popularity of the Industrial Internet of Things (IIoT), industrial Ethernet applications are expanding. The IIoT is helping collect data on plant floors and is using Ethernet cables, connector and switches as key components. Industrial protocols such as Modbus TCP/IP and EtherNet/IP help connect edge devices and instruments to controllers and HMIs. Not only…

Differences Between IT and OT Network Security
Ethernet is used extensively in industrial automation applications, and in the office environments of industrial firms. This leads many to believe the network security procedures used in the office can simply be applied to industrial networks. While this would make implementation easier, it’s not that simple as there are some important distinctions between security practices…

Deterministic Ethernet and TSN | AutomationDirect
Deterministic Ethernet and Time Sensitive Network (TSN) are current industrial automation buzzwords—both related to how control data and information can flow through network pipes. A little history and understanding of industrial fieldbus communications will help explain where we are now and where we’re going with deterministic Ethernet and TSN. The history starts decades ago when…
