Use GuardPLC Controller as an Adapter Chapter 19
Use the Force Editor to Test the Connection
You can use the Force Editor in the RSLogix Guard PLUS! software
and the I/O controller tags in RSLogix 5000 software to test the
connection between the GuardPLC controller and the Logix controller.
Under normal operating conditions, the GuardPLC application
program will change and update the data being read and update the
data being read by the Logix controller. By using the Force Editor, you
can force changes to the input assembly and see this change reflected
in the Logix tag. In the example below, the Force Editor is configured
to display Signal_120_xxxx and Signal_121_xxxx. Signal_120_xxxx is
set in RSLogix Guard PLUS! software and the data is received in the
GPLC_Exclusive_Owner:I.Data tag in RSLogix 5000 software. Likewise,
after GPLC_Exclusive_Owner:O.Data is modified in RSLogix 5000
software, the changes are visible in the Signal_121_xxxx signals in
RSLogix Guard PLUS! software.
Note that the first four bytes in the GuardPLC controller’s output
assembly, Signal_121_0001 to Signal_121_0004, are the Run/Idle
header received by the Logix controller.

PLUS! Software with GuardPLC Controllers Programming Manual,
