HW Data Concentrator - ELVAC RTUs have wide communication abilities. If there are many devices in network, it can be more efficient or necessary to concentrate data in given nodes and send them to upper system. This way, it is possible to collect data from different interfaces and protocols. System can be designed in redundancy, communicate with upper system via two independent channels or it is possible to communicate with subordinated units in ring connection. Modular version of concentrators can be designed as tailor made solution for given application.
SW Data Concentrator - when data is collected from different locations, it is suitable to concentrate them for the purpose of use in SCADA system. Our company offers the product RTU Communicator for these applications, which is succesfully used in power industry already for long time.
