Explicit Messaging
Explicit messaging refers to a request/response form of communications over a CIP (TCP/IP)
connection. Applications can use explicit messaging, for example, to invoke the “Get All
Attributes” service and read all attributes of the Identity object.
1.1.3.2
I/O Connections
I/O connections are used to send data (grouped in assemblies) between devices
periodically. The interval between sends is the “Requested Packet Interval”, or RPI.
The N-Tron switch assemblies (Input, Output, and Configuration) are defined in the
