The Ethernet communication module can access CIP data and services located in connected devices. The CIP objects and their content depends 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 either:
-
a collection of instance attributes, by including in the explicit message address only the object’s class and instance values, or
-
a single attribute, by extending the explicit message address to include not only the object’s class and instance values but also a specific attribute value
When the Ethernet communication module’s local slave service is activated, remote devices can send explicit messages to the module’s CIP object structure and:
-
access module data, or
-
execute module commands
This chapter describes the CIP objects the Ethernet communication module exposes to remote devices.
