What is OPC? OPC means “Open process control” or “Open platform communications” It is a standard that defines data communication between devices from different manufacturers .It Requires an OPC server to communicate with OPC clients .OPC allows “plug and play”, provides benefits as it reduces…
Antennas are vital devices in wireless communication. An antenna is an interface between radio waves that propagate through space and electrical currents that move in metal conductors, which are used with a transmitter or receiver. Basic antenna circuit: Antennas are basically tank…
Introduction A local area network is defined as a computer network that is in the same area and this means that when a user broadcasts any information on the LAN, all users on the LAN receive the transmission. But the only problem…
Introduction As you can see we already discussed about some of the Installation & Troubleshooting of some communication systems in part 1 this section will discuss about AS-i,devicenet, ethernet,TCP/IP if you want to read about part 1 link is given below Part 1…
Introduction When solving problems in a communications system, the engineer or technician tries to use some standard format to arrive at a faster solution. Industrial communications systems do not always respond to proven approaches that worked with wired inputs and outputs. Common…
The communication network is important in process industries to connect different instruments to acquire data from them and to control them. The instruments are connected in different topologies and the connection are made through different network devices, which are main components of a…
Communication between devices connected to computer networks is controlled by transmission and protocol standards and recommendations. These standards are necessary for different vendors to offer equipment and services that interoperate with one another. Protocol standards: There number of standards, standards can…
A HART communicator is a portable device, based on HART communication protocol. A HART communicator works as a secondary master in a control loop. A field communicator supports both HART and Foundation Fieldbus devices. HART communicator devices are used to check variables…
The WirelessHART™ standard provides a robust wireless protocol for the full range of process measurement, control, and asset management applications. It adds wireless capabilities to the HART Protocol while maintaining compatibility with existing HART devices, commands, and tools. A wirelessHART device uses…
What is HART protocol? HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system. HART is owned by independent non-profit HART communication foundation. HART is now…
