This section provides information on CIP messages structure along with information about how to use
CIP messages in a program that runs on a computer or by other means and uses the CIP Communica-
tion Server functions to perform following:
• Writing CIP objects and the values of variables to the NJ/NX-series Controller,
• Reading CIP objects and the values of variables from the NJ/NX-series Controller.
To read and write CIP objects or the values of variables between NJ/NX-series Controllers, use the CIP
communications instructions. Refer to 8-2 CIP Messaging Communications Client Function for informa-
tion about how to use CIP communications instructions for CIP message communications.
