IP Addressing – Networking Fundamentals

No ratings yet.

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.

IP Communication Types

5/5 (1)

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.

Producer/Consumer Messaging vs. Explicit Messaging

5/5 (1)

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.

Producer/Consumer and 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.
