3.3 I/O Messaging (Implicit Messaging)

I/O Messaging also known as Implicit Messaging is used for point to point or multicast
and are used to transmit application specific I/O data. Implicit messages are exchanged
across I/O connections with a Connection Path (predefined path as first defined in
RSLinx and then RSLogix). The Connection will define where the MW100 is located (IP
Address), the Ethernet port on the PLC through which to communicate, as well as what
points are considered inputs or outputs.

The following picture shows RSLinx setup to communicate to the Ethernet device
MW100 (this connection points to an MW100 on the network).

RSLinx Configured with path named MW100

Once a device is configured inside of RSLinx, it can be added to the RSLogix project.
In the case below, ETHERNET-MODULE MW100 points to the networked MW100
configured as a Generic Ethernet Module.
