for a rack-optimized connection, so consider configuring all local I/O
modules for rack-optimized connections.
Use the documentation for the I/O module to determine what data format to
use.
The listen-only communication format works for remote I/O only. Because of
the distributed nature of a DriveLogix system, the DriveLogix controller must
own its local I/O modules. No other Logix-based controller can listen to or
own the local DriveLogix I/O. The DriveLogix controller must produce its
local I/O data for other controller to consume. If you select listen-only for a
local I/O module, the connection to that module will fault.
The following tag structures are possible for a 1794-IA16 module. The
communication format determines the structure that is created for the
module. Assume that the module is in slot 0. The software creates the
appropriate tags using the slot number to differentiate the tags for this
example module from any other module.
communication format: input data (which corresponds to a direct connection for the I/O module)
