A. Digital Outputs This table contains all the output parameters in digital form. They are sorted as per the numerical order of their output label. The following table gives:
-EQ.SYS.LAB.SDI: output label for which the parameter is available,
1EFF : ALL 1 34-48-00Page 21 1 1 Config-1 Aug 01/05 1 1 1CES 1 -PARAMETER DEFINITION: parameter name,
-WORD RANGE/OPER RANGE/RESOLUTION ACCURACY: measurement range. Maximum value transmitted. When the digital value changes, the change step is equal to the accuracy,
-UNIT: unit in which the digital value is transmitted,
-SIG BIT: indicates whether a sign bit is available,
-BITS: number of bits used by the parameter in the label,
-XMSN/INTV: output transmission interval. The refresh rate is given in milliseconds,
-CODE:
BNR: binary data word
BCD: binary coded decimal data word
ISO: data word coded in ISO5 code
DIS: discrete data word
HEX: hexadecimal coded
HYB: mixed code
-ALPHA CODE: indicates the parameter mnemonic code,
-SOURCE ORIGIN: parameter source computer or system.
