I/O Messaging (Implicit Messaging)

I/O Messaging, also known as Implicit Messaging, is used for point to point or multicast and to transmit application speciﬁ c I/O

data. Implicit messages are exchanged across I/O connections with a Connection ID (predeﬁ ned path as ﬁ rst deﬁ ned in RSLinx

and then RSLogix

). The Connection ID will deﬁ ne 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).

Once a device is conﬁ gured inside of RSLinx

, it can be added to the RSLogix

project. In the case below, ETHERNET-MODULE

MW100 points to the networked MW100.
