Configure object data values for explicit messaging (MSG_CIPGENERIC)
To use the MSG_CIPGENERIC function block for explicit messaging, configure the AppCfg parameter with the correct values.
There are several sources of information covering the implementation and use of message communication, including
FactoryTalk Design Workbench
Help, user manuals, and the Rockwell Automation Literature Library.Information source | Description | How to find the information |
|---|---|---|
User manual for your specific communication device | Contains important information about messaging and specific information for configuring message function blocks. | |
Appendix C of EtherNet/IP Adapter 22-COMM-E FRN 1.xxx | Provides information about the EtherNet/IP objects that can be accessed using Explicit Messages. | |
EtherNet/IP specification | Defines the objects to be included in every CIP device: Identity object, Message Router object, and the Network object. | |
Micro800 Programmable Controllers: Getting Started with CIP Client Messaging | Provides quick start instructions for using CIP GENERIC and CIP Symbolic Messaging in Micro830 and Micro850 programmable logic controllers (PLC). |
CIP Register object data
MSG_CIPGENERIC function blocks use the CIP Register object data in the AppCfg parameter. The object data includes:
- Class Code
- Instance
- Instance Attribute
- Service
Values for the MSG_CIPGENERIC AppCfg parameter
Use the values from the CIP register object in your input variables to configure the MSG_CIPGENERIC function block parameters. The following image shows the CIP register object data values used in the MSG_CIPGENERIC function block parameters.
