Most block transfer modules have parameters that you can select. Click the
Configure
button to
display a dialog box to configure the module. For example, here is the configuration dialog for an
8-channel 1771-IFE module.
Enter the configuration data and click OK.
Select how you want the block transfer to update. There are three update modes: automatic,
semi-automatic and manual.
Mode
Description
Automatic
AN-X4-ABRIO-SCAN controls block transfer update
I/O module configuration data comes from AN-X configuration tool
Semi-automatic
AN-X4-ABRIO-SCAN controls block transfer update
I/O module configuration data comes from the ControlLogix
Manual
ControlLogix controls block transfer update
I/O module configuration data comes from the ControlLogix
For automatic and semi-automatic modes, enter the block transfer read and write update rates, from 0
to 16383 ms. A rate of 0 means the AN-X4-ABRIO-SCAN updates the block transfer as fast as the
remote I/O network and the block transfer module allow.
For manual mode, enter the lengths of the block transfer read and write data mapped to the
ControlLogix.
Mapping the I/O Data
You must map the I/O data to locations in the ControlLogix scheduled input and output data before
you can scan the remote I/O network.
Unassigned I/O addresses are shown as xxxx in the network tree.
