After installing the AutoMax AllenĆBradley Remote I/O Scanner
Module, you must prepare it for operation. To do this:
D configure the discrete input and output image table for each rack
in your system by assigning variable names to each used input
and output
D configure the remote I/O racks in your system by assigning
variable names to the remote rack status and control table for
each remote I/O rack in your system
D configure the I/O scanner by assigning variable names to the
scanner setup and status table
D write an initialization program that accomplishes the following:
D sets the remote I/O data communication rate for the scanner
module
D enables the remote I/O racks that the scanner module will
be scanning
D places the scanner in RUN mode and initiates scanning of
the remote I/O adapters
If you are using blockĆtransfer requests to communicate with I/O,
you must do the following:
D configure a blockĆtransfer request by assigning variable names to
the blockĆtransfer status and request table
You will use the blockĆtransfer status and request table to define
the destination and length of a blockĆtransfer and how often it is
to execute as well as to initiate and monitor the request.
D configure the data table used to exchange data between the
scanner module and the target blockĆtransfer module by
assigning variable names to each word used for the
blockĆtransfer
You will use the blockĆtransfer data table to store word or bit data
you have received from or will be sending to the blockĆtransfer
module via a blockĆtransfer request.
D write an application program that sets up and executes a
blockĆtransfer operation
See chapter 14, Configuring and Programming Block Data
Transfers to AĆB I/O Modules" for information about how to program
a blockĆtransfer.
