5.9.2 CIP Data Table Operations
This method of data transfer uses CIP messages to transfer data between the
ControlLogix processor and the module. Tag names define the elements to be
transferred. The following topics describe the support for the read and write
operations.
CIP Data Table Write
CIP data table write messages transfer data from the ControlLogix processor to
the DFNT module. An example rung used to execute a write command is shown
in the following diagram:
The M ESSAGE C ONFIGURATION dialog box must be completed to define the data
set to be transferred from the processor to the module. An example of the dialog
box follows:
Complete the dialog box for the data area to be transferred. CIP Data Table
messages require a tag database element for both the source and destination.
The S
OURCE T AG is a tag defined in the ControlLogix Tag database. The
D ESTINATION E LEMENT is the tag element in the DFNT module.
The module simulates a tag database as an array of elements defined by the
maximum register size for the module (user configuration parameter "Maximum
Register" in the [Module] section) with the tag name
INT _ DATA .
