Overview
The Communications Gateway Module (CGM) provides
a control link between the Electric Fixed Ratio (EFR)
system and a selected fieldbus. This provides the
means for report monitoring and control by external
automation systems.
NOTE: The following system network configuration files
are available at help.graco.com.
• EDS file: DeviceNet or Ethernet/IP fieldbus
networks
• GSD file: PROFIBUS fieldbus networks

ELECTRIC SHOCK HAZARD
To avoid electric shock, make sure the
system power is OFF before connecting or
disconnecting CAN cables.
PRESSURIZED FLUID HAZARD
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashing fluid
and moving parts, follow Pressure Relief
Procedure when you stop spraying and
before cleaning, checking or servicing the
equipment.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment
when in the work area to help prevent
serious injury, including eye injury, hearing
loss, inhalation of toxic fumes, and burns.
Installation
3. Mount the CGM Kit (A) inside the system frame with
two screws (B) and washers (C).
FIG. 3
4. Secure cables (CAN, J) to the frame using the cable
ties (H) provided, and route them through the
protected opening as shown in F
IG. 4.
1. Ensure the system power is OFF and pressure has
been relieved. Follow the Pressure Relief Procedure
in the Electric Fixed Ratio Proportioner, Setup Operation manual.
2. Remove the pump yoke shroud (F) and frame cover
(G) from the EFR system.

5. Connect the CAN cable from either CAN connection
on the CGM to port 2 on the EFR.
NOTICE
Ensure the CAN cable is connected to the appropriate
CAN connection. Failure to connect the CAN cable to
the correct CAN connection can result in damage to
the CGM module.
FIG. 5: Cable Connections
6. If used, connect the Ethernet, DeviceNet, or
PROFIBUS cable (J) to the CGM as applicable.
Connect the other end of the cable to the FieldBus
device.
7. Reinstall the pump yoke shroud (F) and the frame
cover (G) onto the EFR system.
8. Perform the Install or Update Data Map procedure
in the Communications Gateway Module,
Instructions – Parts manual.
9. See Available Internal Data on page 8 for details
regarding the FieldBus pinout setup.
10. Perform the Setup procedure on page 5 to
configure the fieldbus.
NOTE: To produce an accurate dispense, the dispense
valve must be controlled directly by the EFR. See the
Electric Fixed Ratio Proportioner, Setup - Operation
manual for I/O integration of the dispense valve with the
EFR.
NOTE: See Automation Outputs (signals from PLC
to EFR System) on page 22 for information on
triggering a dispense through the EFR using the CGM.

Available Internal Data
Available Internal Data
See Appendix A - I/O Signal Descriptions on page 19
for additional details regarding each input/output.
Unless stated otherwise:
• In each instance, bytes are stored in little endian
order (most significant to least significant).
• PROFIBUS and PROFINET data must be mirrored
by the PLC to get the correct data out on the PLC
side. When the data is mirrored, the least significant
byte is inserted into the most significant spot, and
the most significant byte is inserted into the least
significant spot.
- Example: If the data is a binary number with
0011100110110111, mirroring it to get the
correct data out of the PROFIBUS or
PROFINET will result in 0111101110010011.
• Values are subject to the same maximum and
minimum restrictions as the ADM.
NOTE: Automation Outputs can be monitored by the
corresponding Automation Inputs to verify the EFR
received the data correctly.
