What is RTU?
RTU
(Remote Terminal Unit) is a Remote measurement and control Unit device,
responsible for monitoring and control of field signals and industrial
equipment. Compared with the commonly used programmable controller PLC, RTU
usually has better communication capability and larger storage capacity, which
is suitable for more severe temperature and humidity environment and provides
more computing functions. It is precisely because of the perfect function of
RTU that RTU products have been widely used in SCADA system.
Remote
terminal equipment (RTU) is the electronic equipment installed at the remote
site, used to monitor and measure the sensors and equipment installed at the
remote site. RTU converts the measured state or signal into a data format that
can be sent on the communication media. It also converts incoming data from the
central computer into commands that control the device's functions.
Monitoring
control and data acquisition is a broad term applied to a system that allows
central control and monitoring of equipment installed on remote sites. SCADA
system can be designed to meet various applications (water, electricity, gas,
alarm, communication, security, etc.) and meet customer requirements for design
indicators and operational concepts. The SCADA system can be as simple as a
switch connected to the remote end by a pair of wires or as complex as a
computer network, consisting of many wireless remote terminal devices (RTU) and
communicating with powerful microcomputers installed in the central control
room. The remote terminal equipment of SCADA system can be realized with
different hardware and software. This depends on the nature of the controlled
site, the complexity of the system, the requirements for data communication,
real-time alarm reporting, analog signal measurement accuracy, state
monitoring, adjustment control of equipment and switch control.
