Open a Class 3 Connection
from a Logix Controller
In a Class 3 connection, data is exchanged by using an explicit
message instruction (MSG). Every time the MSG is executed in the
Logix controller, data is exchanged with the GuardPLC controller.
Configure the GuardPLC Controller Assemblies
In RSLogix Guard PLUS! software, set up the appropriate assemblies
and connect the signals. In this example, we connected signals to the
input and output assemblies as shown below.
Make sure the Run/Idle header box is unchecked as Class 3
connections do not use a Run/Idle header.
