Connecting to the PLC from a Remote Location
Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether it’s from the office or from the comfort of your own home. Today’s PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.

Guide to Saving Time with Intelligent Data Logging
With advances in technology and computing power, modern data loggers can reduce the amount of time and effort required to extract critical information. These "intelligent" data loggers incorporate several features that allow them to go well beyond the functionality of a traditional data logger to help zero in on what the user is looking for.
Read MoreWhen Do You Consider Using A Managed Switch?
Many applications will operate properly when using Plug and Play (PnP) switches. Consider the PnP switches as “smart” terminal blocks that you supply power to, plug in RJ-45 connectors with CAT5 cable and devices begin to communicate without any intervention by you. Remember, with a PnP switch,

SCADA/Business Network Separation: Securing an Integrated SCADA System
SCADA systems were traditionally “walled off” from other systems operating independently from the network. Prior to the awareness of possible attacks, this seemed to provide all the protection the SCADA system needed. They were largely proprietary systems with such limited access and esoteric coding that very few people would have the ability to access them to launch an attack. Over time, however, they became integrated into the larger company network as a means to leverage their valuable data and increase plant efficiency. Therefore, the reality is their security is now often only as strong as the security of the network.
Multi-Segment Ethernet Networks
The maximum length of a 10BASE5 segment is 500 m and this would represent the network diameter of the Ethernet network if no repeaters were used. However, Ethernet can be expanded to a larger network diameter by using repeaters as long as the network diameter does not exceed the collision domain of Ethernet. This article will discuss those restrictions.
