To reduce the risk of injury due to electric
shock, remove power to the control panel
before entering the control panel to make
connections for measurement devices.
A network cable is required to use Ethernet/IP
communication with a remote Allen-Bradley
PLC. Insert the network cable into the IF2 port
on the back side of the screen unit.
NOTE:
NOTE:
NOTE: The minimum Requested Packet Interval
(RPI) for this interface is 20 milliseconds.
NOTE:
NOTE:
NOTE: The Ethernet/IP interface uses implicit
messaging. One variable bank is for inputs, and
one variable bank is for outputs.

Contact Graco Customer Support to obtain a
configuration file with the .L5K file extension
needed for this procedure. Then, follow this
procedure to configure the remote PLC to
communicate with the control panel.
NOTE:
NOTE:
NOTE: These instructions are for configuring
an Allen-Bradley PLC using the Studio 5000
software.
1. Import the .L5K file into Studio 5000 to
create a new Studio 5000 project.
NOTE:
NOTE:
NOTE: Contact Graco Customer Support to
obtain a configuration file with the .L5K file
extension.
2. Export the following settings from the
project:
a. The controller tags
b. The “CopyEthIP” program (located under
Tasks)
c. The “AssembInType” and
“AssembOutType” data types (located
under User-Defined Data Types)
3. Open the run-time project, where the
settings from Step 2 will be imported.
4. In the run-time Studio 5000 project, create
the Ethernet/IP communication module.
a. Under Ethernet, select
ETHERNET-MODULE to create a
new generic Ethernet module.
b. Configure the module exactly as the
ETHERNET-MODULE is configured in
the project with the imported .L5K file,
except for the IP Address. Enter the IP
Address assigned to the STU system.
c. After creating the module, set the RPI
to a minimum of 20 milliseconds in the
Connection Properties.
5. Right-click on User-Defined Data Types
and import the “AssembInType” and
“AssembOutType” data types.
6. Import the controller tags: Select
Tools >
Import > Tags and Logic Comments
.
This will create EthIP_In and EthIP_Out data
types in the controller tags with all variables
named in the Variable Interface List.
7. Right-click on the Main Task and import
the CopyEthIP program. Once the CopyEthIP
program is done importing, the configuration
for the Ethernet/IP communication with the
Allen-Bradley PLC will be complete. Modify
the program as needed within bounds of the
protocol.
8. For remote communication, configure the
IP Address, Subnet Mask, and the Remote
IP Address on the Network page of the STU.
See
.
9. Enable the Ethernet/IP communication on
the STU system.
NOTE:
NOTE:
NOTE: Restart the STU to initiate
communication between the PLC and the
STU.

Allen-Bradley PLC variables are prepended with
the following naming structures:
Input: BR2AB_
Output: AB2BR_
NOTE:
NOTE:
NOTE: All output variables correspond to a
variable on the input interface. The output
variables are sent back from the STU so that the
remote PLC can verify that the sent value was
seen by the STU system.
NOTE:
NOTE:
NOTE: The STU must be told which variables
to read from the Allen-Bradley PLC. Set the
AB2BR_networkOverwriteBitfield variable
appropriately to control the STU system
remotely.
