Don't Rule Out The Benefits of EV Ethernet AS-Interface Gateways

Posted by Danius Silgalis on Fri, Apr 21, 2017

AS-Interface gateways control the AS-Interface system and make the process data available to all higher-level networks of the PLC in a defined configuration. Pepperl+Fuchs offers AS-Interface gateways for all standard buses such as EtherNet/IP, PROFINET, PROFIBUS, DeviceNet and CC-Link. When considering EtherNet/IP or MODBUS/TCP gateways for AS-Interface networks, keep these benefits in mind:

Synchronizing Multiple Ultrasonic Sensors

Posted by Sam Horn on Mon, Apr 10, 2017

Ultrasonic sensors are non-contact devices used for object detection or level measurement. They operate on the principle of sound traveling through a medium, where a transducer emits a sound wave at a specific frequency. Based on the time it takes the reflected sound pulse to reach the transducer, the sensor’s internal logic determines if the object is within the nominal sensing range and generates an output signal.

Position Guided Vision for Automatic Guided Vehicle (AGV) Control

Posted by Gerry Paci on Fri, Mar 10, 2017

Automated guided vehicles (AGVs) are used to move product throughout the factory or warehouse floor. Speed and precision are key when moving materials— if you've seen AGVs zipping around in a warehouse, you want to ensure that they stay on track and that they go exactly where they need to, with materials and AGV intact.

The video below discusses the key features and general applications for our PGV absolute positioning system for automatic guided vehicles. The PGV follows Data Matrix codes or colored lines with sub-millimeter precision and is ideal for guidance of AGVs.

From control codes to initiate starts, stops, and turns, to the user-friendly software Vision Configurator, the PGV is packed with the tools you need for any AGV application.

4 Key Attributes for Selecting Ultrasonic Sensors

Posted by Austin Phillips on Fri, Mar 03, 2017

Every sensing technology has its own set of unique capabilities that allow it to perform reliably in certain areas. In dirty environments, a photoelectric sensor’s light beam may fail to return to the receiver due to a covered lens or reflector. However, ultrasonic sensors thrive in dirty and dusty environments, since sound waves are unaffected by dust particles floating in the air or adhering to the sensing face. Industries that commonly use ultrasonic sensors include agriculture, food and beverage, and packaging. The following key attributes will help you select the right ultrasonic sensor for your application.

How to Configure an Industrial Remote Monitor Using VisuNet Control Center Software

Posted by Aaron Severa on Mon, Feb 13, 2017

Process automation plants using industrial HMI often place the equipment in remote locations in the field, away from the process control room or maintenance stations. For busy plant personnel, it's much easier to be able to configure these remote monitors from a centralized location or even off-site remote location. In addition, maintenance and technical support for the daily HMI operators can now be done remotely without needing to physically stand in front of the screen, which is often difficult and time-consuming (pharmaceutical clean rooms, large refineries for example.)

3 Unique Advantages of EV Ethernet AS-Interface Gateways

Posted by Danius Silgalis on Fri, Feb 03, 2017

AS-Interface gateways are the core of the wiring system.  They serve as the link between the sensor/actuator level of AS-Interface and the upper-level bus systems where PLCs (programmable logic controllers), PCs or other field bus systems reside.

Communicating with Your HazLoc Control Panel

Posted by DJ Haney on Fri, Jan 27, 2017

When installing a purged control panel or industrial HMI in a hazardous location, power supplied to the control panel must be regulated so that components are not energized before the panel is protected by a purge cycle.

What Is a Zone 1 Div. 1 Industrial Monitor?

Posted by Mark Lovell on Wed, Dec 14, 2016

What Is the Difference Between Zone 1 and Division 1?

A Zone 1 / Div. 1 industrial monitor must meet the requirements necessary for operating in the presence of ignitable concentrations of gases, vapors, or dusts that are likely to exist, either continuously or intermittently, under normal conditions.  That said, the certification requirements vary according to where you will be using your equipment.
