GuardPLC Controller as a Scanner
The scanner data memory is divided into input and output buffers of
assemblies. The input area is used for signals received from the target
(consumed data). The output area is used for signals transmitted to
the target (produced signals). Each I/O assembly must have a
corresponding signal connection. Signal connections are configured
by using RSLogix Guard PLUS! software. The scanner data memory is
configured via a scanlist by using RSNetWorx for EtherNet/IP software.
To enable the GuardPLC controller to scan I/O, set up the controller
as a scanner. See
Chapter 20 for information on using the GuardPLC
controller as a scanner.
