What is function of RTU?
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory
The RTU (Roof Top Air Handling Unit) provides Heating, Ventilation, and Air Conditioning (HVAC) to the space below. Air Duct Smoke Detectors (Duct Detectors) can be inside the RTU or in the air ducts below the RTU. Douglas Krantz.
- Precision Air Conditioning. Designed for a wide range of applications where close control, high precision air conditioning is essential, including data centre cooling, medium and low density server environments, telecom switching stations, medical operating theatres and clean room environments.
- The process by which the discharge refrigerant from the compressor is cooled down to the condenser saturation temperature. Term. Dew Point. Definition. The temperature at which air reaches 100% humidity; for blended refrigerants, the temperature used to calculate evaporator superheat.

Modbus RTU is an open, serial (RS-232 or RS-485) protocol derived from the Master/Slave architecture. It is a widely accepted protocol due to its ease of use and reliability. Modbus RTU is widely used within Building Management Systems (BMS) and Industrial Automation Systems (IAS).
- Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Versions of the Modbus protocol exist for serial lines (Modbus RTU and Modbus ASCII) and for Ethernet (Modbus TCP).
- RS485 communication: Modbus vs RS485. RS485 is a standard for serial data transmission that is similar to RS232 while using different electric signals. A benefit of the RS485 protocol is the ability to have several devices share the same bus.
- In comparison, Profibus' specification document is thousands of pages long. The term “Modbus” typically refers to one of three related protocols: Modbus ASCII, Modbus RTU, or Modbus TCP/IP: 1. Modbus ASCII was the first Modbus and is a serial protocol, typically running on either the RS-232 or RS-485 physical layer.
A remote terminal unit (RTU) is a multipurpose device used for remote monitoring and control of various devices and systems for automation. It is typically deployed in an industrial environment and serves a similar purpose to programmable logic circuits (PLCs) but to a higher degree.
- PLC & Scada Workshop. Programmable Logic Controller or PLC is a computing system used to control electromechanical processes. SCADA stands for Supervisory Control and Data Acquisition. It is a type of industrial control system that is used to monitor and control facilities and infrastructure in industries.
- A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit (MAU). An air handler designed for outdoor use, typically on roofs, is known as a packaged unit (PU) or rooftop unit (RTU).
- Saving lives following the expansion of centralized remote telemetry monitoring. Continuous monitoring of patients throughout the hospital is a desirable method to ensure the continuity of quality care.
