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. 606 $aData transmission systems$xStandards 606 $aSpecifications$xStandards 615 0$aData transmission systems$xStandards. 615 0$aSpecifications$xStandards. 676 $a004.6 801 0$bWaSeSS 801 1$bWaSeSS 906 $aDOCUMENT 912 $a996281045003316 996 $aIEEE recommended practice for master$92573296 997 $aUNISA
