These types of systems typically utilize dedicated communication channels, such as private microwave channels or leased telephone lines, which are limited to data rates of less than 10 000 bits/s. Wideband local networks used for high-speed data acquisition and control functions are excluded. This standard covers the communication channels, channel interfaces, message format, information field usage, and communication management. A standard message protocol is defined to the octet level, rather than to the bit level; most details at the bit level are left to the manufacturers of SCADA equipment to define and implement.Data transmission systemsStandardsSpecificationsStandardsData transmission systemsStandards.SpecificationsStandards.004.6WaSeSSWaSeSSDOCUMENT996281045003316IEEE recommended practice for master2573296UNISA
