Parameter
Description
DataInput,
arraynamename
both AN-X modules
ClxName
ClxName is used in the address part of the aliases
for elements that are unique for each AN-X, such
as diagnostics. It is usually set equal to the
Ethernet host name.
ClxPrefix
The ClxPrefix is used in the alias name for I/O
data. It should be the same for both AN-X
modules in a redundant application.
RedundEna
Include a line with the RedundEna parameter, followed by a comma and
a unique name for the AN-X at the start of the ControlLogix
configuration file.
RedundPrefix
AN-X uses the RedundPrefix when it generates aliases for elements that
are unique to each AN-X module, such as diagnostics.
RedundCtl
RedundCtl consists of a single 16-bit word. Only bit 0 is used. To
enable an AN-X to act as the scanner, set bit 0 to 1. To disable the
AN-X, set bit 0 to 0.
Map RedundCtl to the output data for the connection to slot 0 in each
AN-X. If the configuration file contains RedundEna, you must map
RedundCtl.

operation of the Modicon S908 network scan.
