1. What is Ethernet Protocol? Ethernet/IP is basically an application layer protocol and is a flexible best-in-class Ethernet network. It is a simple way of arranging data inside a TCP/IP packet. On Ethernet/IP network, data is known as attributes and is represented by values. They are grouped altogether to create objects. 2. How Ethernet/IP protocol …
The DNP3 or distributed network protocol is a communication protocol that is used to do the communication between the industrial devices. It is utilized to monitor several industrial data, DNP3 protocol is widely used in the SCADA network. This protocol is widely utilized by several electric and water utilities. It can do critical remote communication …
What is a MODBUS? MODBUS is a communication protocol that is used for many industrial applications. This communication protocol can be used to do the data transfer between the process control equipment and the HMI. MODBUS was developed by MODICON to communicate with industrial electronic devices such as PLC, PAC, or DCS over a twisted …
What is a hub A hub can connect our PC to a network, it would help to reach information around the network and it also helps the connected device to communicate. A hub is mostly used in LAN connections, it has multiple ports and it acts as a common connection point for the devices in …

Communication networks are used in the process industry to exchange information between sensors, actuators and controllers. Controller Area Network (CAN) bus generally being used for communications between vital controllers and a slower network such as the Local Interconnect Network (LIN) being used for less critical tasks. Control Area Networking Working: The CAN network has a …
What is OSI ? Open Systems Interconnection (OSI) model was approved as an international standard for communications architecture by International standard organization (ISO). The word “open” refers to the capacity to link any two structures that conform to the model of reference and related norms. The OSI model explains how information or data move from …
What are Fieldbus coupling devices? Fieldbus coupling equipment (often informally referred to as bricks) are used inorder to simplify the job of linking Fieldbus equipment to such a network segment. So that the end user does not have to construct and commission junction boxes using conventional terminal blocks. A photo of a Fieldbus coupling device …
Gateways, Bridges & Routers are the interconnecting devices in a network topology. The internetworking device must simultaneously satisfy the physical requirements and access requirements simultaneously while translating data frames from one form to another. There are three, commonly used devices which perform the role of the internetwork interface between OSI systems: Gateways Routers Bridges. Gateway: …
