Allen-Bradley Communication Types and Protocols

Industrial automation has long been at the heart of many of the improvement in manufacturing and process efficiencies across many industries. And the ability to use standardized applications to control devices and equipment at a speed and precision greater than that possible by human range of motion and reaction is one of the key reasons for that reality. As the digital revolution as grown, it has ushered in an accelerated need for improved and evolving control over such devices to handle new capabilities and new inputs from a data stream that is growing exponentially. Even more than a smart home or a connected individual, factories, warehouses, and supply chains are becoming more and more connected to leverage this connectivity to add value to their processes and improve competitiveness. As a result, the sophistication and capability of the communication types and protocols used to drive PLCs and other control equipment has grown and evolved as well. In this article we’ll cover the...

DeviceNet and ControlNet, What’s the Difference?

Industrial automation applications range from straightforward to extremely complex depending on the industry. For those just beginning their digital transformation, starting simple and then scaling as the value becomes evident is an accepted path. For others with the technical skillset and IT infrastructure in place, more complicated data needs may dictate a broader and deeper path to digitization. There are other factors to consider as well. For many companies, ROI is high on the list moving forward. And it may also depend on practical factors such as the number of devices that may need to be controlled off multiple I/Os. Finally, practical considerations such as facility layout and age of legacy equipment in a factory may point toward a specific solution as there is still a considerable amount of older manufacturing equipment that needs to be retrofitted. While having the latest and greatest technology is considered optimal, it may not be practical or necessary given considerations...

ProfiNet vs EtherNet/IP – Similar, Yet Different

When you talk about industrial communications these days, two terms tend to show up more than others, EtherNet/IP and ProfiNet. The reasons for this familiarity are simple, these two communication protocols are two of the most common in industry. They are two of several Industrial Ethernet based communication protocols and share the market with other Fieldbus protocols as well. As Ethernet based communications are gaining market share each year, these two protocols will become more prevalent. Both protocols utilize and add on to standard Ethernet technology. One benefit to this is that, with some care in selection, Ethernet/IP and ProfiNet networks do not require specialized equipment for their infrastructure. Standard Cat(x) copper cabling or fiber optic cable, network switches, patch panels, and other standard network devices can be used to build the control network. Care does need to be taken in product selection when designing the control network. Higher capability cabling, such...

A Beginners Guide to CIP Safety

This may be your first time reading about CIP safety. Welcome, we will talk about how this protocol works as well as its similarities and differences with standard communication protocols. While this will be a technical overview, we will not discuss safety programming specific topics, but instead an overall picture of how CIP safety fits into the evolving industrial automation industry. Over the past decade, with the advancements from hard-wired safety relays to programmable network-monitored safety devices, it is necessary to understand how this technology works and how you can benefit. It is important that everyone from business managers to engineers understand how this technology can be used to save cost as well as increase safety. What is CIP Safety? Is there special hardware for CIP Safety? Does CIP Safety communicate differently to a PLC (Programmable Logic Controller)? How is CIP Safety used in Industrial Automation? Are there programming differences when using CIP Safety? So...
