In this article we will be implementing Layer 2 NAT with Layer 3 routing as shown in the the network topology depicted below. For this example we will be leveraging two Allen-Bradley Stratix 5700 Managed Industrial Ethernet switches (Full Software Version) and three Logix based controllers (machines). With Stratix 5700 NAT capability configured, we can setup a NAT instance per VLAN. When we create multiple VLANs on one Stratix 5700 switch we can connect multiple identical machines and leverage Layer 3 routing to route between the various VLANs.
Stratix 5700 Smartports are the recommended configurations for switch ports. These configurations, referred to as smartport roles, optimize the switch connections and provide security, transmission quality, and reliability for traffic to-from the switch ports. The smartport roles also help prevent port misconfigurations.
We are excited to announce a new video series we are working on right here at PLCGurus.NET on our Learn PLCs page and on our YouTube Channel. In this video series we are going to walk you through, in explicit detail, how to create your own Custom HMI-SCADA application using C#, Visual Studio and the .NET programming tools. Through the use of INGEAR NET.LOGIX API’s and drivers we can empower our C# applications to connect directly to any Allen-Bradley Logix based Controller.
Manufacturing stands on the brink of a new industrial revolution. While the last revolution was powered by machinery and fossil fuels, this one is driven by unprecedented access to data and advances in technology otherwise known as Smart Manufacturing.
Smart Manufacturing allows manufacturers to optimize their production and supply networks and aims to take advantage of advanced information and manufacturing technologies. There is increased workforce training required for such flexibility and use of the technology rather than specific tasks as is customary in traditional manufacturing environments.
I thought I would do a piece on the System Overhead Time Slice setting you will find in pre- L8 (5580) Allen Bradely ControlLogix and CompactLogix platform of controllers. As the complexity and connectivity of modern automation systems get more complex requiring high-performance communications, I/O, and motion control , careful consideration must be taken to ensure that both user-defined and back-end system tasks are optimized to mitigate the likelihood of CPU starvation.
Ethernet technologies and Ethernet/IP protocols are an integral part of today’s industrial automation systems. In this, IP Addressing Fundamentals video, I explain in explicit detail, what an IP Address is and how it functions, what a Subnet Mask is and what it’s used for, and finally the role of the Default Gateway.
An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address or IP Addressing serves two principal functions: host or network interface identification and location addressing.
In this video I will cover the various IP Communication Types used in Industrial Ethernet networks today.
Gone are the days when electricians and engineers spec and pull bundles of I/O conductors and interlock wires to-from machinery, robotics, and automation systems. As a result running 1-1/2 to 2-1/2 inch conduits containing an abundance of control wires is a thing of the past. Now, we can run much smaller conduits that contain merely a network cables or cables, and perhaps a couple of low voltage power cables to power our network enabled devices.
In this video I will show you step-by-step how configure the your new Stratix 5700 using the Stratix 5700 Express Setup Mode.
While the Express Setup itself is meant to be an easy method by which to configure the Stratix 5700 managed switch, it can be a little daunting initially. As a result, you can waste a considerable amount of time just trying to get passed the initial setup.
Hopefully, this video will alleviate that “pain” and get you up and running and into the switch as quickly as possible. I do recommend, if you haven’t done so already, you check out our introductory video on how to Configure PC to PLC Communication as part of our Networking Essentials video series. Alternatively, you can view it on our YouTube Channel!
In this video I will show you how to configure PC to PLC communication over an Ethernet network. One of the biggest challenges I see with maintenance personnel and engineering support staff alike is the configurations necessary to configure their laptop or PC’s network settings to be on the same network as the PLC controller they are trying to connect.
As a result, the field service technician is unable to get online with a controller to perform the necessary troubleshooting task. To alleviate this problem, I have created a step-by-step YouTube video that walks the user through exactly how to perform these tasks.
In this article I will explore two different methods by which a PLC programmer can pass information to-from multiple ControlLogix controllers, namely, the producer/consumer messaging model and the explicit messaging model.
While both models will effectively transmit data from one or more controllers to one or more controllers over a network, depending on the requirements of the application, a PLC programmer may be inclined to choose one model over the other.
