G. High level DC Similar to low level DC information but the measurement range is different. The value to be transmitted on the output bus is proportional to the input voltage provided it is between 0 and 4OV. An NCD coded SSM, bits (30,31)=(1,0), on the output label, indicates an input voltage of less than -2V.
H. High Level AC AC voltage measurements where the measurement range is between 0 and 160VRMS. Between 10 and 160V, the transmitted value is proportional to the voltage. A failure warning coded SSM, bits (30,31)=(0,0) indicates the absence of an AC input voltage and an offset voltage of less than -10V.
J. Frequencies The same input terminal as high level AC is used. On the output label, the frequency is transmitted when it is between 300 and 500Hz for a voltage between 80 and 200V. When the input voltage is less than 80V, zero is transmitted.
K. Resistances The parameters to be transmitted are temperatures. The measurement range is between 68.27 and 242.70 ohms. An NCD coded SSM, bits (30,31)=(1,0) on the output labels corresponding to these parameters, indicates an open circuit on the input or a short-circuit.
L. Power Supplies and Miscellaneous
Power supply for concentrator and pins dedicated to maintenance.
3. Interface
_________
A. Interface Tables This table contains all the output parameters in the digital form. They are sorted as per the numerical order of their output label. The following table gives:
-SYS LABEL SDI: SDAC ouput label for which the parameter is available
-PARAMETER DEFINITION: parameter name
-RANGE 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
-DATA BITS: number of bits used by the parameter in the label
-UPD/MSEC: output transmission interval. The refresh rate is given in milliseconds
-CODE:
BNR : binary data word
BCD : binary coded decimal data word
R 1EFF : 001-049, 051-099, 101-105, 151-156, 1 31-54-00Page 3 1201-203, 1Config-1 May 01/05 1 1 1CES 1
ISO : data word coded in ISO 5 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.
