Overview

The remote I/O adapter module can access CIP data and services located in connected devices. The CIP objects and their content depend on the design of each device.

CIP object data and content are exposed and accessed hierarchically in the following nested levels:

NOTE: You can use explicit messaging to access these items:

  • Access a collection of instance attributes by including only the class and instance values for the object in the explicit message.

  • Access a single attribute by adding a specific attribute value to the explicit message with the class and instance values for the object.

When the local slave service for the adapter is activated, remote devices on the remote I/O drop can send explicit messages to the CIP object structure of the module. Then you can access module data or execute module commands.

This chapter describes the CIP objects that the adapter exposes to remote devices.
