——Product Application——


Compared with the commonly used programmable controller PLC, RTU usually has excellent communication capabilities and larger storage capacity, suitable for harsher temperature and humidity environments, and provides more computing functions. RTU products are widely used in SCADA systems in industries such as oil and gas, water conservancy, power dispatching, and municipal dispatching.


Today, RTU technology is developing in the direction of intelligence. The intelligent RTU can automatically determine whether the acquired data needs to be reported to the central control station immediately, or it can be temporarily retained locally and then transmitted later, or until the central control station requests it. Intelligent RTU can automatically detect the interruption of communication and immediately start saving data to the memory, so that the communication network can be used most effectively. The intelligent RTU can also transmit those critical data to several central control stations at the same time. In addition, because security is the biggest problem in the current communication network, intelligent RTU can encrypt data before transmission, and can also deny access from unknown addresses.
