Table/Module
Configuration
The following figure shows the table/module configuration.
Given the above sample configuration, if you select 300001 as the starting address
of the status table and there are no I/O modules in the first two locations, the first
I/O module status is found in the least significant byte of the second word
(i.e., position 3). The table fills until the last I/O mapped module is found.
Note: The bit pattern reported in each status/error byte is dependent on the module
type.
