GE X3.28 manual Configuring the Partition Definition Table A197PAR

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		This parameter specifies the type of data that the partition will
		Analog Input		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.
