Introduction The CAN bus was developed by BOSCH as a multi-master, message broadcast system that specifies a maximum signaling rate of 1 megabit per second (bps). Unlike a traditional network such as USB or Ethernet, CAN does not send large Read more…
Importance of Profibus In an industrial automation system, communication between PLC, SCADA, HMI or any other automation devices is essential to pass information. Process field bus, Profibus is actually an industrial communication protocol used for real-time data exchange. Profibus, which Read more…
HART communication protocol Highway Addressable Remote Transducer(HART) is an open protocol suitable for digital as well as analog purpose in an industrial automation field. It is widely used in process and instrumentation control, which ranges from small applications to highly Read more…
Over the last few years, our energy needs have changed, and they will continue to change in future, so our grid needs to be updated to help cope with demand. This is why the smart meter roll-out is so important. Read more…
Before any data collection or remote sensing can be achieved, information needs to be passed between the sensors and the communications system in a form that is compatible with the language of the SCADA system. To accomplish this, a field interface unit is required. Read more…
A Remote Telemetry Unit (RTU) is a digital based electronic device. A device can collect data’s from the real world and transmit that data’s without loss to the specific object (Controller, software etc.,). We called that device name as Remote Read more…
Modbus Communication is a Communication Protocol used in PLCs for Communication between a Master/Slave. Modbus is used for transfer of information over the Serial lines between the Master and Slave. Modbus is just a set of rules for data transmission. Read more…
