3.2.8 AIL_ - Analog Input - LIL
AIL_ function blocks are available when the optional LIL
communication board is installed. They allow the
controller to obtain global data from other stations on the
LIL. AIL block numbers are assigned in sequence with
each use, station wide. The data is received in the LIL
format having a standard range of $80 to $F80. The block
output is a real number and is scaled in engineering units
using the MIN and MAX SCALE parameters. The Output
Range is a special data type that includes the MIN and
MAX SCALE, the DPP, and the ENGUNITS that can be
connected to other blocks having a Range (RG PTR)
input.
Output QS indicates the quality of the received data and
will go high (1) when the data is bad. This is normally
associated with failure to receive global data due to a LIL
failure or a misconfiguration of the source.
The AIL function can be assigned to a single LIL channel. It will then have certain data that will be accessible over
the LIL. Parameter 1 is the received data (RD) in the $80-$F80 format and will be re-transmitted by this station on
the assigned channel. This LIL CHAN parameter can also be set to 0. The controller will still receive global data
from the other station but the received data will not be re-transmitted and the other channel data (i.e. MINSCALE,
...) will not be accessible..
