6-20 Communicating with Devices on an EtherNet/IP Link
Communicating with Another Logix-based Controller
All Logix-based controllers can use MSG instructions to communicate with
each other. The following examples show how to use tags in MSG
instructions between Logix-based controllers.
The source and destination tags:
• must be controller-scoped tags.
• can be of any data type, except for AXIS, MESSAGE, or
MOTION_GROUP.
Communicating with other controllers over EtherNet/IP
The DriveLogix5730 controller also uses MSG instructions to communicate
with PLC and SLC controllers. The MSG instructions differ depending on
which controller initiates the instruction.
For MSG instructions originating from a DriveLogix5730 controller to a
PLC or SLC controller:
Type of MSG Instruction: Example Source and Destination:
Logix-based controller writes to Logix-based
controller
(CIP Data Table Write) source tag
destination tag
array_1
array_2
Logix-based controller reads from
Logix-based controller
(CIP Data Table Read) source tag
destination tag

writes to PLC-5 or
SLC In the DriveLogix5730 controller, specify the source data type
based on the destination device:
PLC-5: SINT, INT, DINT, or REAL
SLC: INT, REAL
Example source element: array_1
Specify the destination file type based on the
destination device:
PLC-5 typed write: S, B, N, or F
PLC-5 word-range write: S, B, N, F, I, O, A, or D
SLC: B, N or F
Example destination tag: N7:10
