Part 1 – Ethernet/IP Description
1.1 General
Q46 Analyzers are available with four digital communication options. Profibus-
DP, Modbus-RTU, Modbus-TCP/IP, or Ethernet/IP.This manual applies only to
instruments supplied with the Ethernet/IP communication option. It is critical to
note that Ethernet/IP devices only communicate with other systems running the
Industrial Protocol of Ethernet. You cannot plug a Q46 into your office Ethernet
and expect to have the Q46 talk to your computer.
The discussion of standard Ethernet and Ethernet/IP is vast, and well
beyond the ability to discuss here in great detail. The documentation for
this option assumes working network knowledge by the user.
1.2 Ethernet/IP Communication
Ethernet/IP was first introduced in 2001, and is a highly developed and complete
protocol for an industrial Ethernet network solution. Intended for automation
applications, EtherNet/IP is a member of a family of networks that implement the
Common Industrial Protocol (CIP) at its upper layers of the standard ISO/OSI 7-
layer model. CIP defines the object structure, specifies the message transfer,
provides users with a unified communication architecture, and encompasses a
comprehensive suite of services for a variety of manufacturing automation
applications which include data, control, safety, and configuration.
In the CIP Protocol, every network device represents itself as a series of objects.
Each object is simply a grouping of the related data values in a device. The
identity object contains related identity data values called attributes. Attributes for
the identity object include the vendor ID, date of manufacture, device serial
number and other identity data.
The Q46 utilizes a gateway device inside the analyzer that maps an internal
Modbus data structure into the required Ethernet/IP data object. This is done to
maintain plug-and-play compatibility to all Q46 digital communication options.
Any communication option can be plugged into any Q46 for immediate
conversion to a new protocol.
Because this gateway device is part of the Q46 interface, the ID and device type
show up on the interface as the gateway device. However, the Q46 variation
type is mapped into the application data object as the last byte.

1.3 Ethernet/IP Transmission Details
It should be understood that Ethernet/IP is simply an application layer protocol
that is transferred over an Ethernet hardware link. The word "Ethernet" simply
refers to the common physical cable, perhaps running to an office PC.
In the OSI model, “Ethernet” is the lower part of the model, the physical transfer
method or the hardware. It says nothing about the way information is
transferred, which is specified near the top of the OSI model. In the common
office network, many different standard communication protocols are operating
during normal office use, like IP, TCP, etc. None of these are designed to handle
the CIP industrial format, so that interface must be handled by a specific program
that recognizes the format. Because of this, an Ethernet/IP device cannot be
directly connected to your office network for transferring information.
The data for the protocol is constructed into a specific structure inside a standard
TCP/IP Packet. A user application program simply decodes the structure inside
the received TCP or UDP packet. The data structure consists of a grouping of
data values called Attributes inside other sets of containment data called Objects.
There are Ethernet/IP required Objects and application Objects. Required
objects are typically - Identity, TCP, and Router. Application objects consist of
some defined data types, like a Motor Object, and some user specific data
types.
1.4 Ethernet/IP Card Installation Instructions
Use the following instructions to install the Ethernet/IP Communications Option
into an existing Q46 Analyzer. Monitors ordered with the Ethernet option will be
supplied with the board already installed.
1. Disconnect power to the Q46 prior to installation of the board.
2. Remove the connector cover on the power supply circuit board located next to
the fuse.
3. Carefully plug the Ethernet/IP circuit board into the connector on the power
supply board.
4. Align the cover board holes with the holes in the circuit board and use the screws
supplied to secure the assembly. Refer to Figure 1 on the next page for the
proper assembly.

1.5 Cable Connection
The cable used for Ethernet/IP communication should meet the CAT5 standard
defined by the Electronic Industries Association and Telecommunications
Industry Association. It is readily available in lengths up to 100 ft. (30 m) with
plugs on each end.
To install an Ethernet cable in the Q46, pass the unterminated cable through the
cable gland nearest the location of the RJ45 connector on the Ethernet/IP option
board. Termination of Cat5/5e/6 cables is very easy and can be completed
quickly with the commonly available RJ45 crimp tool.
Figure 2 - RJ45 Crimp Tool
While professional results are optimized with the use of the termination tool and
custom cable lengths, patch cord style connection can be completed in some
cases by passing the finished RJ45 connectors through the Q46 cable gland.
The connector will fit through the plastic part of the cable gland, and the rubber
grommet can be slit (some RJ45s may be too big for this.) Once the connector is
inside the enclosure, simply plug it into the jack provided on the Ethernet/IP
communication board. Be sure to adjust the rubber insert in the cable gland so
that the slit is on the bottom and then tighten the gland to seal around the wire.

1.6 Interface Operation
Once the proper power is applied to the Q46 monitor, select “Ethr” in the ^Host
Comms listing of the OPTIONS menu on the Q46 to enable Ethernet/IP
functionality.
On power-up, the Q46 looks for a BOOTP server to assign an IP address.
Standard PLC networks (like Rockwell-RSLinx) include this server as part of the
system. If no response from BOOTP occurs after about 60 seconds, the Q46
system defaults to an IP address at 192.168.0.254. The data is stored in an
object with the attributes shown below, and can be acquired with an Ethernet/IP
PC test program using the explicit message format as follows –
Service: 14 (0x0E hex, Get_Attribute_Single)
Class: 4 (0x04 hex, Assembly Object)
Instance: 101 (0x65 hex, Input Instance)
Attribute: 3 (0x03 hex, Data Attributes)
As an example, this call is shown in the Molex Ethernet/IP software tool screen
shot below, run on the default IP address of a Q46D. This free Molex PC tool
can be used to test explicit messages on the Q46 interface. To run this on a PC
for check-out, the user must first be sure to set the IP address of the PC Ethernet
port to the 192.168.0 subnet range, like 192.168.0.20 (or, manually run a BOOTP
server.) This tool cannot be used to set a fixed IP, and is primarily useful as
a quick verification tool.
Figure 3 - Molex Ethernet/IP Explicit Message Tool Example

ATI Q46 Ethernet/IP Communications Manual
8
In the Molex example, the explicit message sent to the Q46D is (all hex) –
14, 03, 20, 04, 24, 65, 30, 03
This “Get Attribute Single” call requests the EIP data object at
Class = 4
Instance = 101
Attribute = 3
The raw response shown above from the Q46 is shown below -
8E, 00, 00, 00, 00, 00, 00, 00, 07, 01,
00, 00, BC, 09, 00, 00, 3E, 01, 00, 00,
00, 00, 00, 00, 31, 00
Since Ethernet/IP is a Little Endian protocol, the raw response format above is
byte-swapped. To more easily see the data, flip every odd byte to Big Endian
fomat. Then, underline our Q46 defined data sets –
00, 8E, 00, 00, 00, 00, 00, 00, 01, 07
00, 00, 09, BC, 00, 00, 01, 3E, 00, 00,
00, 00, 00, 00, 00, 31
Breaking up the groups, here is how the response corresponds to the Q46D
instrument data set. The first 4 bytes are header info for the interface. Two
bytes for status will appear in the data object and then 20 data bytes start after
those status bytes -
0x008E0000 = 4 bytes (32 bits) of header (not visible to PLC)
Data object next…
0x0000 = 2 bytes (16 bits) of internal status info (ignore)
0x00000107 = 32-bit value = 263 = 2.63 ppm Dissolved Ox
0x000009BC = 32-bit value = 2492 = 24.92 C Temperature
0x0000013E = 32-bit value = 318 = 31.8 % Saturation
0x00000000 = 32-bit value = 0 PID
0x00 = 8-bit binary value = 0x00000000 Status 1 flags
0x00 = 8-bit binary value = 0x00000000 Status 2 flags
0x00 = 8-bit binary value = 0x00000000 Alarm flags
0x31 = 8-bit value = 49 ID
In most PLC’s, the 4-byte header will not show in the data object, but the 2-byte
internal status header will. You can just ignore that status register when parsing
data that starts at the 7th byte.
Note that in the section 1.9 Data File tables below, we count the first table byte
as the first data byte –starting after the 6 byte header/status info So, the first 32-
bit data value is listed as bytes 1-4, the second data value is at bytes 5-8, and so
on.

1.7 PLC Settings
PLCs handle this exchange in a wide variety of configurations, and the
configuration of a class 1 connection in every PLCs software is different, but
there should be a place to enter the following information. If this doesn't seem to
make sense, follow the explicit info above.
Data Type: "INT" or "16-Bit"
Input T->O Assembly Instance: 0x65 or 101 decimal
Input T->O Size: 11 words (16-bit)
Output O->T Assembly Instance: 0x66 or 102 decimal
Output O->T Size: 1 word (16-bit)
Configuration Assembly Instance: 0x80 or 128 decimal
Configuration Size: 0
*Note that there may be a byte swap occurring on each set of registers as
Ethernet/IP is Little Endian (see parse above in section 1.6). So you may have to
byte swap each 16-bit register to recombine the data.
**Note that section 1.6 shows that first raw 4 header bytes as being ignored, as
the raw bytes are all shown with a Molex PC tool. The 2 raw bytes will show on
the PLC, and are simply an internal status register. So, actual data shows right
after those 6 bytes.
Note that some Ethernet/IP Master simulators such as EIP Scan do not have
data type settings, everything is in bytes. In that case, the input above would be
22 instead of 11.Make sure to double check whether entry values are in hex or
decimal.
1.8 Configuring fixed IP with BOOTP
The Q46 acquires a dynamic network IP address from the network client/master
through the BOOTP service, which is enabled by default for ODVA EIP-CIP
conformance. However, a fixed IP can be set using BOOTP on a PC.
BOOTP is a very simple software server application that waits for a specific MAC
address to appear on the network, and then assigns it a pre-determined IP
address that has been set-up by the user. In the most actual applications,
BOOTP runs right on the PLC alongside tools like Rockwell’s Studio 5000. For
manual fixed settings, this same BOOTP server tool can be easily run on a PC.
The current Rockwell version of this tool (recommended) is –
“BootP-DHCP Ethernet/IP Commissioning Tool Version 3.03.00”

ATI Q46 Ethernet/IP Communications Manual
10
This BOOTP tool is available from the Rockwell Automation website for free. For
optimum security, only download this tool directly from Rockwell Automation.
https://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?
crumb=112
While this tool is normally used for dynamic assignment, the Q46 will remember
the last successful assignment made by BOOTP, and it will retain that
assignment after cycling instrument power. Therefore, the tool can be used to
lock in a fixed IP address assignment, and then the BOOTP service will not
actually be required after that first assignment.
In order to use BOOTP properly on a PC, some careful NIC adjustment settings
must be made to the PC Ethernet port prior to running the BOOTP service. The
PC can only reach IP addresses at the predetermined IP/subnet level, so we
must force the PC to a subnet that can reach the existing Q46.
1) Turn off Q46. Connect Q46 to laptop with direct cable. Set laptop NIC port
on a locked IP and subnet to stop DHCP service. This is critical. In IPV4
properties on your PC’s Ethernet connection port, select "Use the
following IP Address" and set the PC to -
IP Address = 192.168.0.10
Subnet Mask = 255.255.255.0
See below –
Figure 4 –Force PC to Specific Network Subnet Prior to Running BOOTP
2) Once this IP/subnet is set, click OK to save and then close it all out. Turn

ATI Q46 Ethernet/IP Communications Manual
11
PC off then back on to place it on the new IP address set in step 1. The
PC will now be able to access any network device on 192.168.0.X, as the
subnet mask 255.255.255 locks in the first three variables. The default
value for the Q46 is 192.168.0.254, so it can now be reached by the PC.
3) Find the Rockwell BOOTP PC application and launch it. Select your
Ethernet Adapter as the network interface.
Figure 5 –Launching BOOTP server
4) On next screen, you must create an assignment relationship to match a
known MAC ID with a desired IP address. The MAC ID for your Q46 is
written on a label inside the enclosure, and always starts with 00:80.
For this example, we will use the MAC ID - 00:80:A3:9B:BE:B6 and
assign it a fixed IP of 192.168.0.30. Hit OK after this information is filled
in, and you will see this entry appear in the bottom half of the window
under “Entered Relations.”
Once the MAC assignment has been entered, it is ready for a BOOTP IP
request to come in for assignment. Requests for assignment will appear
in the upper window as they come in.

ATI Q46 Ethernet/IP Communications Manual
12
Figure 6 –Setting IP/mask Assignment in BOOTP Server
5) Now, plug the cable from Q46 into the PC Ethernet port, turn on power to
the Q46, and wait for BOOTP to detect the request from the Q46 for an IP
address.
The upper “Discovery History Window” will show new IP requests coming
in on the Ethernet port, and when the specific MAC ID in our relation
shows up, the IP will be automatically assigned per our relation entry and
sent to the Q46. Note that you may see requests from other devices as
they come in, but only the specific MAC ID from the assignment will be
acknowledged.
Figure 7 –Successful Detection of MAC ID and IP Address
Assignment in BOOTP Server

ATI Q46 Ethernet/IP Communications Manual

Once the assignment has been made and the IP has been sent to the
Q46, disconnect power to the Q46 and that IP will be stored in the
instrument. The Q46 stores the very last successful IP address
assignment. Then close out all BOOTP server windows.
6) Now, to check that the IP address has been properly saved, apply power
to Q46 again and make sure it is connected to PC Ethernet port. Do not
launch BOOTP server this time, as you don’t need it.
Wait 1 minute, as Q46 will search for a BOOTP server for about 30
seconds on power up and won’t find the service because you are not
using it here. It will then revert to the stored default –the last successful
BOOTP assignment. You can check the IP connection to the Q46 at that
address by entering a ping command at the Windows OS command
prompt, for example “>ping 192.168.0.30.” You should see a response
as shown below. In addition, you can try and “>arp -a” command to show
all current connections and associated MAC addresses. You should see
the new IP address of 192.168.0.30 showing up.
Figure 8 –PING and ARP Command Tests for IP Address Setting.
Note that the “arp -a” listing still shows this IP as a “dynamic” assignment,

ATI Q46 Ethernet/IP Communications Manual
14
as this is the fall-back IP that has been stored in the Q46. On power up,
the Q46 will still try and find a BOOTP server for 30 seconds, and then
default to this stored value as the fallback. If you do not see your new
connection, two troubleshooting notes –
1-You must always be careful to place the new IP address on the proper
subnet level so the PC can still reach it with the settings made in step 1. If
the PC is on 192.168.0.X, then any assigned IP must be on the X level –
and don’t place the Q46 on the same IP as the PC. During BOOTP server
assignment, if you place the Q46 on a vastly different IP like
10.20.120.100, you must repeat step 1 before step 6 above to place the
PC at something like 10.20.120.10. This can get tricky, as you can make
assignments anywhere, but then the PC must be re-established on that
new net to find the new assignment.
2-Remember to wait a minute before the ping test if you verify a
connection. The Q46 runs BOOTP by default on power-up, so it will be
searching for that server for about 30 seconds on power up, and then will
default to the stored IP.

1.9 Ethernet/IP Data Files
The data organization shown in section 1.6 corresponds to the same mapping as
all the other communication interfaces on the Q46. All Q46 instruments provide
20 bytes of input data to the master, and the meaning of the bytes changes
slightly depending on which Q46 instrument is used.
