Graco Gateway Overview
Graco Gateway Overview
The Graco Gateway enables the ProMix 2KS to network
with a programmable logic controller (PLC) via one of
the supported protocols (Ethernet, DeviceNet, or Profibus).
NOTE: Only persons very familiar with their PLC
communication architecture should use this hardware and software. This manual assumes that the
person using the Graco Gateway has full understanding of the PLC equipment and related software.
Network communications essentially operate with
the same rules as Discrete I/O. However, network
communications require placing correct values or
adjusting appropriate bits within various Modbus registers (for example, see Table 4). These changes
should only be made by qualified persons familiar
with this type of communication.
Install the Gateway
Module Hardware
Location
This equipment is not for use in explosive atmospheres. Do not install equipment approved only for
non-hazardous location in a hazardous area.
Install the Gateway module near the EasyKey™, in a
non-hazardous area.
Mounting
1. See Dimensions, page 66.
The module allows for most PLCs to communicate with
the ProMix 2KS via Modbus RTU protocol by bridging
the gap between the desired communication protocol
and RS485 Modbus RTU. As a result, the PLC has full
access to all the registers for monitoring and controlling
the ProMix 2KS. It is the responsibility of the integrator
or user to ensure proper configuration of the communication hardware on the PLC side.
2. Ensure that the wall and mounting hardware are
strong enough to support the weight of the equipment, cables, and stress caused during operation.
3. Using the equipment as a template, mark the
mounting holes on the wall at a convenient height
for the operator and so equipment is easily accessible for maintenance.
4. Drill mounting holes in the wall. Install anchors as
needed.
5. Bolt equipment securely.
Grounding
Your system must be grounded. Read Warnings,
page 4.
The Gateway module is grounded through its connection to the EasyKey, which must be connected to a true
earth ground. See the system installation manual. A
ground wire and clamp, part no. 223547, is available
from Graco.

Modbus and I/O Data
Modbus and I/O Data
See Table 4 through Table 5 for Modbus register
addresses and input/output data.
Reference the Discrete I/O listing of all the inputs and
outputs (see page 23). Ensure these are fully understood. The same implementation used for Discrete I/O is
used for the Network communication protocol.
For example: The Gun Trigger Input will now be a specific bit of Modbus Register 40040. Monitoring of Modbus Register 40041 for specific output status conditions
will be required as explained in the Discrete I/O section
of the ProMix 2KS Operation manual. The PLC will have
to read the various bits, and in some cases (40040 and
40041 for example) must mask out the various bit positions to determine each of the separate input and output
statuses. This requires experience and should not be
done on the job site. A full understanding of the color
change process as well as the required timing of various
inputs and outputs is required.
NOTE: Analog input for flow control set point will
now be a dedicated Modbus register. Register
40137 will require the specific flow rate (i.e. 125
cc/min). This is not a voltage reading but the actual
flow target.
Color Change Process
1. Verify that Mix Ready is set. This ensures that there
are no alarms and that the system is ready for the
next command.
2. Load ccNewRecipe (Modbus 40046) with a recipe
number to color change to.
3. Set color change (40040 bit 6).
4. Verify that Purge_CC_Active is seen (40041 bit 0).
5. Clear color change bit (momentary only).
6. Do not change the ccNewRecipe value until a new
recipe change is requested.
7. The color change process will stop automatically as
programmed. Monitor Purge_CC_Active bit for completion.
Purge Process
1. Verify that Mix Ready is set. This ensures that there
are no alarms and that the system is ready for the
next command.
Start Mix Process
2. Set purge (40040 bit 8).
1. Verify that the Mix Ready bit (bit 2 of 40041) is on.
3. Verify that Purge_CC_Active is seen (40041 bit 0).
2. Turn on the Mix bit (bit 7 of 40040).
4. When Purge_CC_Active bit clears, clear
Purge_Start bit. Clearing this bit in the middle of a
purge sequence will abort the purge sequence.
3. Verify that the Mix Active bit (bit 1 of 40041) is on, to
ensure that the Mix request was received.
Stop Mix Process
1. Clear the Mix bit.
2. The Mix Active output should clear and Mix Ready
should now be set.
NOTE: The ProMix 2KS will automatically go into
Idle mode after 2 minutes of inactivity. A general
alarm will be present and Mix Active will remain High.
The Alarm bit (40010) will indicate the system Idle
alarm. When a new Gun Trigger input is seen, the
ProMix 2KS will resume mixing material where it left
off. Do not toggle the Mix bit; doing so restarts the
Mix process from the beginning.

Troubleshooting
Serial Communication Troubleshooting
This section is used to troubleshoot the communication between two devices linked via serial ports, i.e. RS232 or
RS485.
TIP: For communication troubleshooting, it is strongly advised to create a new Graco Gateway database including
only one data tag mapped to a known register in the target device.
PROBLEM
Values show “----”
CAUSE
SOLUTION
Port settings do not match.
Check that the port settings of the
Graco Gateway device match the target device (i.e. Baud, Parity, etc.).
Incorrect target device address.
Check that the target device address
in Graco Gateway (in communications on the PLC symbol) matches
the target device address setup.
Incorrect cable.
Check the cable part number or
cabling to match your protocol.
Incorrect communication port.
Check if the cable is connected to the
correct communication port.
If the above is correct, check that the
protocol settings are on the correct
communication port in Graco Gateway.

Incorrect tag mapping.
Check that the tag is mapped to an
existing register in the target device.
Incorrect tag mapping on one of the
tags on the display.
Delete tags one after another and
download in-between. When the values on the screen stop blinking, the
last deleted tag was mapped incorrectly or accessed an unknown register in the target device.

Appendix A: DeviceNet™ Slave Communication
Appendix A: DeviceNet™ Slave Communication
Overview
This appendix describes the Gateway’s support for DeviceNet and details the configuration steps necessary to
use this feature. It does not provide a detailed description of DeviceNet, but only a brief introduction, necessary to define the terms that are used throughout the
remainder of this document.
Introduction
DeviceNet is a low-level network using the Controller
Area Network (CAN) technology, to provide communication between a range of industrial devices, from simple
devices such as sensors and actuators, to high-level
devices such as controllers and HMIs.
•
CAN_H
Position 4 of the pluggable connector provides the
CAN_H bus line (active high). This terminal is isolated from the Graco Gateway.
•
V+ (optional 24 Vdc)
Position 5 of the pluggable connector is provided for
optional 24 Vdc connections. This position is available only to tie 24 Vdc wires together. The DeviceNet option card neither provides or uses 24 Vdc
power through this connection. The V+ position is
not connected to any circuitry internal to the DeviceNet option card or Graco Gateway.
DeviceNet Port Protocols
The DeviceNet option card has one DeviceNet port. See
FIG. 25. The port may be configured for various DeviceNet protocols. Contact Graco Technical Assistance for
currently supported protocols.
Also see Appendix A: DeviceNet™ Slave Communication on page 36.

Appendix A: DeviceNet™ Slave Communication
About DeviceNet
•
I/O Poll Connection: The Poll connection is an I/O
connection over which Poll command and response
messages are transferred. The Poll command is
transmitted by the master, and is directed to a single
slave device. The slave device in turn responds with
a Poll response message. Both the Poll command
and Poll response messages can contain any number of bytes.
•
I/O Data Connection: The I/O Data connection is
part of the Predefined Master/Slave Connection Set,
but instead is included for devices, which support
creating I/O data connections via the UCMM
(Unconnected Message Manager).
DeviceNet is a connection-based network. In this context the term connection refers to a communication path
between two or more devices, and not the physical
(cable) connection to the DeviceNet network. A connection must be established between two devices in order
to transfer data.
There are two types of connection defined by the DeviceNet specification. Each has different characteristics
and is suited to a specific type of communication.
•
•
I/O Connection – Dedicated data transfer between
a producer and one or more consumers. The format
of the data is known or implied by the connection.
Level of Support
Explicit Messaging – Generic multi-purpose messaging connection, typically command and
response message commands.
The Gateway provides Group 2 Server level support: A
UCMM capable device that is configured to act as a
Slave for the Predefined Master/Slave connection set.
Each connection type has an extensive number of
parameters, which can affect the characteristics of the
communication path. For many Master/Slave communications scenarios, a defined set of connections, together
with their respective parameter settings exist under the
collective name Predefined Master/Slave Connection
Set. Many of the steps involved in creating and configuring a connection have been removed with this connection set, thus simplifying the network configuration.
Predefined Master/Slave Connection Set
The DeviceNet specification details a number of connections that facilitate data transfer between a Master
and Slave devices. The following sections detail the connection types supported by the Gateway.
•
38
I/O Bit-Strobe Connection: The Bit-Strobe connection is an I/O connection over which Bit-Strobe I/O
command and response messages are transferred.
The Bit-Strobe command is broadcast by the Master
device and is received by all slave devices simultaneously. The command message contains a single
bit of information for each slave on the network.
Each slave device is required to respond with a BitStrobe response message. The response message
can contain up to 8 bytes of information.
312785A
Appendix A: DeviceNet™ Slave Communication
Hardware
To use DeviceNet on the Gateway, an option card must
first be installed. The option card provides the hardware
necessary to support the CAN physical layer specification as required by the DeviceNet standard.
Configuring the option card is a two-stage process; first
the option card must be selected in Gateway (DeviceNet
Option Card), and then the ‘DeviceNet Predefined
Group 2 Server Driver’ configured to run on the newly
created DeviceNet Interface port.
Configure the Gateway DeviceNet Option
Card
Install the Gateway DN0000 option card in the Gateway
as per the provided instructions.
Click on File>New to create a new Gateway database
and select Gateway Series HMI – Gateway 10.
Enter the Communications section. In the tree on the
left, select Gateway from the top of the tree. Select the
Edit button at the right, and select the DeviceNet Option
Card from the dialog box as shown in FIG. 26. Click OK.
Gateway Configuration
The following example requires use of an Allen Bradley
1756-ControlLogix PLC, along with RSLogix 5000 and
RSNetWorx for DeviceNet software and a Gateway.

NOTE: For 16-bit support, select Word as Word. For
32-bit support, select Word as Long. The latter is
recommended as DeviceNet uses 32 bits integer
addressing.
Set the block size for 4, and the Direction for: Device To
Gateway. This will be the Read Data block.
FIG. 30: Select Data Type (Word as Long)
312785A
43
Appendix A: DeviceNet™ Slave Communication
Select the second Gateway Block and set it up for I/O
Polled Response Data 00000, with a length of 4, and the
Direction Gateway To Device. This will be the Write Data
Block. FIG. 31 shows both Gateway blocks once completed.
FIG. 31: DeviceNet Block Mapping
NOTE: Read and Write are from the Gateway point
of view. This means the master can send data in
Block A, so the Gateway can read data. On the other
hand, the master can only pull data from Block B, so
the Gateway can only write data.
DataP – Identifies the I/O Produced Data (Slave to Master).
The addressing scheme available is outlined below:
BitC – Identifies the I/O Bit-Strobe command data (Master to Slave).
BitR – Identifies the I/O Bit-Strobe response data (Slave
to Master).
PollC – Identifies the I/O Poll command data (Master to
Slave).
PollR – Identifies the I/O Poll response data (Slave to
Master).
DataC – Identifies the I/O Consumed Data (Master to

Appendix A: DeviceNet™ Slave Communication
Automatic Update of the EDS File
DeviceNet nodes use an EDS (Electronic Data Sheet) to
describe the communications parameters available at
each device on the DeviceNet network.
Gateway provides an EDS file generator tool to create a
file that matches your Gateway settings. This file can
therefore be used to configure the Master.
By design, each DeviceNet master can handle a maximum of 124 Input words and 123 Output words. In the
default EDS file for the Gateway, the Input and Output
data sizes are set at 16 bytes each. This equates to four
words of data input and four words of data output. These
values can be set higher, but it is important to note that if
the default values are set higher, they might conflict with
other DeviceNet implementations.
To generate this file, enter the Communications module
and select the DeviceNet interface on the left. Under the
Electronic Data Sheet, select Yes in Synchronize and
choose the path and name where the file should be
saved using the Browse button. FIG. 32.
FIG. 32: Automatic EDS Update
Saving the database using the File>Save command will
synchronize and therefore update the EDS file.
NOTE: Inputs and Outputs are with respect to the
master, therefore inputs refer to data sent from the
slave and read by the master.
Each time EDS parameters are modified, the EDS file
will need to be re-registered within RSNetWorx for DeviceNet. These changes will also need to be reflected in
the following locations:
•
RSNetWorx master node Scanlist, Input Table, and
Output Table
•
ControlLogix PLC DeviceNet Scanner configuration

Appendix A: DeviceNet™ Slave Communication
Configure the RSNetWorx for DeviceNet Software
RSNetWorx for DeviceNet is used to set up and manage
a DeviceNet network. To begin the configuration, launch
RSNetWorx for DeviceNet from your development PC.
Make sure that the .EDS file validation is successful.
Start a new network by selecting: File>New>DeviceNet
Configuration.
Register the EDS file generated by Gateway as shown
in the previous section of this document by selecting:
Tools>EDS Wizard>Register an EDS file(s).
FIG. 35: EDS Validation
If desired, select a new image file to represent the Gateway.
FIG. 33: Register the EDS File

the left. Navigate to: DeviceNet>Vendor>Graco Controls>Generic Device. Select the Gateway-SERVER and
drag it into the network workspace at the right.
Configure the master to add the slave device to the
scanlist. Right click the DNB module and select properties.
FIG. 37: Review EDS Registration
From the Scanlist tab, select the Gateway-SERVER
from the Available Devices pane, and add it to the Scanlist pane. Select the Edit I/O Parameters button.
FIG. 38: Configure the DeviceNet Master
312785A
47
Appendix A: DeviceNet™ Slave Communication
Make sure that the Strobed or Change of State boxes
are not selected. In the Polled section, verify that the
Input and Output sizes are 16 bytes. These must match
the I/O Poll Size selections made above in the Gateway.
In DeviceNet networks, 4 bytes constitute a full word.
Therefore the 16 bytes selection represents 4 full words
of addressable 32-bit data.
Select the Input tab. Verify that the four words of Gateway-SERVER data are mapped to YourDNBSlot:I.Data[0…3]. From the Output tab, verify that the
four words are mapped to YourDNBSlot:O.Data[0…3].
Apply the changes, and save your RSNetWorx for DeviceNet configuration.

Appendix A: DeviceNet™ Slave Communication
Configure the DeviceNet Scanner to be address 0.
Make sure to set up the 32-bit Input and Output memory
spaces for a size of 32 (to match the configuration made
above in both Gateway and RSNetWorx for DeviceNet).
Select the RSNetWorx tab, and navigate to the RSNetWorx for DeviceNet configuration that you have previously created. Open the configuration from here and
download it to the network.
FIG. 41: Main Task Tree
In the Main Task tree, open the Main Routine Ladder
Logic file. Create a rung of ladder to enable the DeviceNet network. The required output is always:
Local:YourDNBSlot:0.CommandRegister.Run
Create a few rungs by taking the DeviceNet Input data,
Local:2:I.Data[0…3], and adding 1 to them. Store the
results in Local:2:O.Data[0…3]. Based on the configuration in the Gateway, if values are changed on the Gateway Write tags, the Read tags will display the respective
values, plus one.
Wire the DeviceNet Network
All DeviceNet networks require a termination resistor at
the two end nodes on the network. Place a ¼ watt 120
ohm resistor between CAN H (White) and CAN L (Blue)
of the DeviceNet connection.
Save and download this configuration to the ControlLogix PLC.

Appendix B: Profibus™ DP Slave Communication
Overview
This appendix describes the Gateway’s support for Profibus DP and details the configuration steps necessary
to set up a Graco Gateway with an S7300 PLC,
CPU315-2DP via Profibus. It does not provide a
detailed description of Profibus, but only a brief introduction, necessary to define the terms that are used
throughout the remainder of this document.
The protocol supported by the Profibus DP option card
is Profibus DP Slave. Therefore, the Graco Gateway
must be linked to a Profibus network with a PLC.
Profibus Port Protocols
The Profibus option card has one Profibus port. See
FIG. 42.
Also see Appendix B: Profibus™ DP Slave Communication on page 51.
Introduction
Profibus DP stands for “Profibus for Decentralized
Peripherals”. Profibus DP is a device level bus that supports both analog and discrete signals. It has widespread usage for such items as remote I/O systems,
motor control centers, and variable speed drives. Profibus DP communicates at speeds from 9.6 Kbps to 12
Mbps over distances from 100 to 1,200 meters.

Appendix B: Profibus™ DP Slave Communication
About Profibus DP
Profibus DP communication takes the form of block
exchange. Profibus blocks are made of memory bytes
where 2 bytes make a word and 4 bytes a double word,
or Dword.
A block is a range of consecutive byte addresses and is
unidirectional. This means the PLC will exchange data
read only and write only blocks with DP slave units.
Addresses in each device are independent and only relevant to the device for its own program. For example,
the address range for the first block in the master can
start at 256 with a 64 words block length and could
result in the slave with a range starting from 0 with 64
words length.
However, since blocks are consecutive, this means the
first block start address, in the above example 256, will
be the slave start address 0. Then, 257 in the master
would be 1 in the slave, and so on.
Block length can be defined in bytes, words, or double
words. Since start addresses between the master and
the slave can be different, one could give its start
address and length in bytes, and the other in words.
For example, the master start address is byte 256, with
a 64 words block length.
•
This results in a range from byte 256 up to byte 383.
The slave start address is word 0, with a 64 words
block length.
•
This results in a range from word 0 to word 63. FIG.
43 illustrates this exchange.
NOTE: Do not forget that the Input block is independent from the Output block, and although the
address range is the same, the data are different.
NOTE: FIG. 43 has no connection with the Input
Block and Output Block in Graco Gateway. The terminology used in the tags configuration is from the
PLC point of view (DP Master). Refer to Graco Gateway Setup for more information.

Add the Graco Gateway to the Profibus Network
To add the Graco Gateway to the Profibus network, drag
the Gateway Profibus Card from the Catalog navigation
situated on the right hand side of HWConfig to the Profibus DP Master System. The card is situated under Profibus DP>Additional Field Devices>MMI.
In the properties window that popped up, select the Profibus address the Gateway will take on the network. This
address should be unique. In this example, the Gateway
will take address 5. FIG. 52. Click OK.

Appendix B: Profibus™ DP Slave Communication
The Gateway is now on the Profibus DP network and
selected. HWConfig shows the slots available under the
Gateway to configure the data blocks to exchange.
Just drag and drop one of the data blocks available
under the Gateway Profibus Card in the slot number 1.
Simatic will automatically assign a start address (byte
number) in the respective Input and output columns
depending of the block type chosen. In this example, 64
words in and 64 words out.
More blocks can be inserted in the following slots to fit
your application. FIG. 53 shows an example with a 16
words input block in slot 2 and 5 words output block in
slot 3. Addresses are given automatically but can be
edited by the user.
NOTE: If the starting address for a block in slot 2 or
above changes and creates a gap in the address
range, it will not affect the Gateway blocks, as all
data are consecutive. It is however advised to keep
the addresses consecutive to facilitate development.
FIG. 53: Configure Data Blocks
Save the configuration and download it to the PLC.
NOTE:

Graco Gateway Setup
Once the PLC is setup, the Gateway can be programmed to fit its configuration.
NOTE: For a Gateway to communicate on Profibus
DP, a Profibus Option card has to be fitted in the unit.
Refer to the device manual to find the proper option
card and installation procedure.
Setup the Profibus Communication
Enter the communication module and select the Gateway. On the right hand pane, click the Edit button to
select the Option card. Select Profibus Option card and
click OK. FIG. 54.
FIG. 54: Select Profibus Option Card

312785A
Appendix B: Profibus™ DP Slave Communication
The option card appeared in the communication tree.
Select the Profibus Interface and click the Edit button to
select a driver. Click OK to pick the Profibus DP driver.
FIG. 55.
FIG. 55: Select Profibus Server
Graco Gateway now displays the driver settings where
the Station Address can be changed. This address is
the Gateway address on the Profibus network. In our
example, this address is 5 as setup in the PLC earlier.
NOTE: There are no Baud Rate settings as the Profibus option card detects the transmission rate automatically.
A device called PLC1 is now displayed under the Profibus Interface. This device represents the Profibus Master and can be renamed to fit the application. In this
example, the name PLC1 remains. FIG. 56.

Appendix B: Profibus™ DP Slave Communication
Setup Tags
Once the communication is set up, tags can be created
to access the PLC blocks. This is where the section
Setup the Profibus Communication, page 60, is
important.
First, create a variable that correspond to the data type
required. In this example, an integer. FIG. 57.
FIG. 57: Create a Variable
Select the variable and rename it eventually. Then, click
on Internal next to mapping on the right hand side pane,
and select PLC1, which is the Profibus Master. FIG. 58.
Select PLC1 from
pulldown menu
FIG. 58: Variable Properties
62
312785A
Appendix B: Profibus™ DP Slave Communication
In the popup window, select the block type required. Two
choices are available:
•
Input block: The terminology input is from the Siemens perspective. Therefore this will be a block the
Gateway will write to. The tag mapped to an input
block has to be set up as Write Only.
•
Output block: The terminology output is from the
Siemens perspective. Therefore this will be a block
the Gateway will read from. The tag mapped to an
output block has to be set up as Read Only.
•
Select the data offset, which points the address to
read or write in the block. Select the data type to
read or write. This defines how many bytes to
access in the block to get the correct data. In this
example we choose output block, with data offset 0
(Which points to 256 in the PLC) and as a Word.
FIG. 59.
FIG. 59: Select Block Type
NOTE: Since the output block is a reading block from
the Gateway standpoint, this variable should be set
up as Read Only as shown in Fig. 19. The same rule
applies if the block is an input block, it should be set
up as Write Only.
To avoid mistakes, the mapping shows with an R or W
for output or input block respectively. FIG. 60.

How Addressing Works
The Gateway addressing follows a different scheme, as
shown in FIG. 62.
PLC addressing is in byte and uses the scheme shown
in FIG. 61.
This means that the address number will be different
when accessing words or Dwords in the Gateway data
tags than the PLC. Table 6 shows the address relationship for integer tags mapped as word in the Gateway.

Useful Formulas
The following formula can be used to find the byte number from a word address:
ByteAddress = PLCOffset + (WordAddress x 2), where:
•
ByteAddress is the address we are looking for in the
PLC
•
PLCOffset is the first byte number in the complete
block mapping in the PLC, here 256
•
WordAddress is the address mapped in the Gateway. So, for example, word 77 in the Gateway,
would start at byte 410 in the PLC, and so would be
composed of byte 410 and 411.
The following formula can be used to find the byte number from a Dword address:
ByteAddress = PLCOffset + (DWordAddress x 4),
where:
•
ByteAddress is the address we are looking for in the
PLC
•
PLCOffset is the first byte number in the complete
block mapping in the PLC, here 256
•
DwordAddress is the address mapped in the Gateway. So, for example, Dword 14 in the Gateway,
would start at byte 312 in the PLC, and so would be
composed of byte 312, 313, 314 and 315.
NOTE: For the formula to work, all the blocks in the
PLC Profibus configuration for the Gateway have to
be consecutive. FIG. 52.
