6.2 LIL DATA MAPPING
LIL data is assigned to one of two data types. The first is global data which occupies parameter 1 of each channel
and is transmitted by the LIL interface every 0.5 seconds. The remaining data is non-global which occupies
parameters 2 through 256 and is transmitted in response to a LIL READ command or can be changed by a LIL
WRITE command.
Each parameter is a 16-bit word. An IEEE floating point number (Real) is assigned to 2 consecutive parameters
with the first containing the most significant and the second the least significant portion of the floating point
number. String data can occupy one or more consecutive parameters. The following tables provide an overview
listing of available data with descriptions located in Section 7. The acronym in the table identifies the data in
Section 7. Data can be accessed using the Model 320 Independent Computer Interface. Refer to AD320-10 Model
320 ICI User Manual and AD320-20 Guidelines for Writing Application Software Using the Model 320 ICI.
Guidelines:
All individual parameters (words) can be read using the random parameter data request (CMD 7). Parameters that
span multiple words, such as floating point, ASCII tags, etc., can also be read using the multiple-byte parameter
data request (CMD 23) but only one variable can be requested at a time. Writes are made using the parameter data
send (CMD 9). In some cases such as loop and alarm status words, the MASK ON/OFF type codes are used to
identify individual bits. Not all bit mapped words support this option. See Section 7 for specific information.
6.2.1 Station Data
Station data is fixed and occupies the first seven channels.
