Chapter 5: Configuring the Partition
Definition Table (A197_PAR)
The A197_PAR table contains one record for each data partition defined for each SRU. A data
partition is a continuous range of X3.28 word addresses that contain sub-system data. The range
of records for a particular SRU is specified in configuration table A197_SRU by the First
Partition and Number of Partitions parameters. Each SRU can have more than one of each type
of partition.
Name Range Description
Data Type Digital Input
Analog Input
This parameter specifies the type of data that the partition will
contain. Digital Input partitions require 16 digital input system
points per word. Analog Input partitions require one analog input
system point per word.
Start Address 0 .. 32767 This parameter specifies the word address of the first word in the
partition. Each partition must have a range of addresses that is
unique to all other partitions mapped by the same SRU record. In
other words, partitions that are mapped by the same SRU record
should not have ranges that overlap.
Number of Words 1 .. 32767 This parameter specifies the number of 16-bit words in this
partition. Note that Analog Input partitions require an even number
of words.
For Digital Input partitions, each word requires 16 digital input
system points.
For Analog Input partitions, each SRU analog input point value
requires two words and each word requires 1 analog input system
point.
