One of the requirements in industrial automation networks for outstations is data collection and control equipment that serves as an interface between lower-level devices and sensors with SCADA systems. These devices are called Remote Terminal Units (RTUs) and Programmable Logic Controllers (PLCs), which are highly diverse and primarily produced by foreign companies with very few Iranian examples. After conducting research and development, Data IDA-Ltd has been able to produce a fully indigenous device called RTU-LOTEX DCU, which has various capabilities of RTUs and can easily replace foreign examples. The name DCU stands for Data Collecting Unit.
