Chapter 6 Using Explicit Messaging
Example Ladder Logic to Write Multiple Parameters
Formatting a Message to Write Multiple Parameters
Scattered Write Multiple Message Configuration Screens
The following table identifies the data that is required in each box to configure a
CompactLogix controller message to write multiple parameters.
IMPORTANT
This example scattered write message writes to NVS. Over time, continuous
writes will exceed the EEPROM life cycle and cause the drive to malfunction.
If you need to make frequent parameter changes using Explicit Messages, set
Host parameter C121 [Comm Write Mode] to 1 “RAM only”.
