Overview
The Communications Gateway Module (CGM) provides
a control link between the HFR, VRM, or VPM system
and a selected fieldbus. This provides the means for
remote monitoring and control by external automation
systems.
The following kits work with kit 24J415 and includes all
remaining parts necessary to install a CGM. See manual 312864 for repair parts for each assembly.
CGM Part No. Fieldbus
CGMDN0 DeviceNet
CGMEP0 EtherNet/IP
CGMPB0 PROFIBUS
CGMPN0 PROFINET
The data available by the CGM to the fieldbus depends
on which GCA based system is connected. Unique data
maps are defined for each GCA system and are available on the token provided in the kit.
See Available Internal Data on page 9 for a list of internal data from the HFR, VRM, or VPM system that can
be viewed or modified by your fieldbus master.
NOTE: The following system network configuration files
are available at www.graco.com
• EDS file: DeviceNet or Ethernet/IP fieldbus networks
• GSD file: PROFIBUS fieldbus networks
• GSDML: PROFINET fieldbus networks

additional extension cables, see GCA CAN Cables
Reference manual.
NOTICE
To avoid severe damage to GCA modules, ensure
the CAN cable is connected to the appropriate CAN
connection.
A
NOTICE
To avoid severe machine damage, do not connect
any CAN device to connectors 2A, 2B, or 2C on the
Motor Control Module. Connectors 2A, 2B, and 2C
are not CAN connectors.
NOTE: CAN ports are located on the base of cube
shaped GCA modules or port 6 on the High Power Tem-
D
perature Control Module.

Install Upgrade Tokens
NOTE: The Motor Control Module, Fluid Control Mod-
ule, and Temperature Control Module connection to the
system is temporarily disabled during the installation of
upgrade tokens.
To install software upgrades:
1. Use correct software token stated in the table. See
Graco Control Architecture
manual for instructions.
NOTE: Upgrade all modules in the system to the
software version on the token, even if you are
replacing only one or two modules. Different software versions may not be compatible.
All data in the module (System Settings, USB Logs,
Recipes, Maintenance Counters) may be reset to
factory default settings. Download all settings and
user preferences to a USB before the upgrade, for
ease of restoring them following the upgrade.
See manuals for locations of specific GCA components.
The software version history for each system can be
viewed in the technical support section at
www.graco.com.

CGM initiates a square wave that
toggles every 3 sec. The PLC must
follow the heartbeat. If the heart
beat is lost from the PLC or CGM
then the system will shutdown. If the
PLC does not detect the heartbeat
then the PLC should cycle the PLC
output bit HI/LO in attempt to establish the heartbeat from the CGM. If
no heartbeat is detected then a disconnected cable or major error may
exist in the CGM.
Monitor Only: On Circulation systems, this indicates that a dispense
is pending or in progress (or when
pre dispense timer is active and during a dispense).On an L-head system Dispense Valve is considered
open until the end of the clean out
cycle. On other types of systems the
bit will indicate a dispense is active.
Used in diagnostics only. Not to be
used to control a dispensed shot.

cycle will dispense material out of
the Ratio Check valves when in
Ratio Check mode. When bit is OFF
the material will dispense normally
thru the Dispense valve.
Parking the pump involves moving
the Red pump to the position which
the pump shaft is least exposed to
the atmosphere. System must be in
Standby mode. Chemical will dispense out of the dispense valve.

Initiates a fill valve open. This bit
can be used to initiate a manual fill
cycle or a auto fill cycle if the auto fill
mode is selected. The tank fill valve
will close upon reaching the high
level switch. See Byte 79 for tank
level status. If the Tank fill bit is
maintained the GCA will close the
valve when the tank is full. Auto time

reached within a preset time.

Errors requiring acknowledgement
are presented on first in first out
basis. The latest error is currently in
the error register in the CGM. The
PLC must send back the exact
ASCII value for the error to be
acknowledged in the CGM. If an
incorrect ASCII error code is sent
back to the CGM then the error will
not clear and the CGM register will
be overwritten with the incorrect
error. If multiple error codes exists
then the PLC must acknowledge
them in the order the errors are sent
to the PLC from the CGM. See
bytes 80-83 and 84 for errors and
status.

Controlling Device
CGM Control and Night Mode
When the controlling device sets the HFR into night
mode using the CGM, the controlling device will be
responsible for turning on and off the pumps accordingly
(by setting or clearing the “SYSTEM STARTUP BIT”, or
bit 7 bytes 1-2) when the “CGM Control Enabled” bit is
set (Bit 14, bytes 1-2). Any active night mode periodic or
time of day timer will be over-ridden by the controlling
device when the corresponding timer expires within the
Advanced Display Module (ADM). If the controlling
device clears the “CGM Control Enabled” bit after setting the HFR into night mode, the night mode timers will
operate properly and condition the dispense material
accordingly.
CGM Control and Parking the Pumps
After the HFR is set to Standby mode, the controlling
device (and user by pressing the footswitch) will have
the option to park the pumps. When the pumps are
parked, the red material pump shaft will be immersed
into the red material, hence preventing exposure of the
shaft and red material on the shaft to the atmosphere.
ADM Screen Information when CGM
Control is Started or ended
When the user or controlling device sets or clears the
“CGM Control Enabled” bit, information provided on the
ADM display may or may not be current. If the user navigates away, then back to the main home run screen, the
information provided will be current.
If the system is a full circulation based system, the controller device will need to have the pumps cycling in low
pressure mode (by setting the “SYSTEM STARTUP
BIT”, or bit 7 bytes 1-2) prior to setting the “Pump
Parked” bit (bit 4, bytes 1-2). For a standard HFR, the
user will have to remove the “SYSTEM STARTUP BIT”
immediately after the pump reaches the parked position.
For a recirculation type system, the pump will remain in
the park position, and ignore an active “SYSTEM
STARTUP BIT” request. For a recirculation type system, to exit a parked state, the controlling device will
need to clear the “Pump Parked” bit, then set the “SYSTEM STARTUP BIT” from a cleared state. When this
occurs, the pumps will start cycling in the last low pressure flow rate executed.
If the system is a stall to pressure type system, the controlling device simply needs to set the “Pump Parked” bit
from an idle state, then the pumps will move to the
parked position. If the system has a manual dispense
valve, the user will need to ensure the pump pressures
are less than approximately 391 psi (2.7 MPa, 27 bar)
prior to setting the “Pump Parked” bit, and ensure either
the dispense valve is opened, or the material is diverted
out of the pressure relief valves at the material manifold.
