This is Part 2 of our “25 Things to Consider when Choosing an OPC Tunnel” series. How does the tunneler handle security?
Security is an integral consideration when choosing a tunneling solution. This blog will cover some important aspects of security to consider when evaluating different tunneling solutions.
Barcode scanners are one of those types of devices that are extremely common in a variety of industries, whether it's for use in a manufacturing process or for cataloging inventory or a multitude of other possible uses. But how do you go from scanning a barcode to making that barcode data available to your monitoring applications such as an HMI or a SCADA?
Over the years of working in the automation software realm, I've seen dozens of clients have this seemingly basic need to bring barcodes up into various software packages. Regardless of the make/model of the scanner, the process is almost identical. For example, you could connect to a DataLogic scanner in under five minutes. (Click for How-To Video)
This post will cover the steps for bridging that gap between your scanners and your client applications.
With the majority of companies in the oil, gas, railroad, water, wastewater, mining and power/utilities industries requiring wide area distributed radio networks for communications, engineers in charge of these radio networks have the daunting task of maintaining the highest level of performance and uptime at all times.
Given that you're reading this, I will choose to make the assumption that you are either an engineer in charge of such a radio network or that you've had some interaction on some level with such a radio network and it may not have been an altogether pleasant experience.
We're going to discuss a few things to keep in mind if you're interested in getting the most uptime possible out of your serial radios (and, let's face it, why wouldn't you want that).
