Composer Elite Operating Manual
1.1 Introduction
Composer Elite™ is designed to measure the precursor concentration of binary
gases. It is optimized for operation at pressures as low as 26.66 kPa
[200 Torr] and temperatures as high as 65°C. The Composer Elite System
provides unsurpassed precision and reproducibility when measuring small
concentrations of heavy molecular weight components in a lower molecular weight
carrier gas.
1.1.1 Description of the Composer Elite System
The Composer Elite System consists of:
A Sensor Control Unit which sends/receives electrical signals to/from the
Acoustic Sensor. The Sensor Control Unit provides an LCD display and
interface for user interaction (see Figure 1-1).
An Acoustic Sensor which interfaces to the process gas tubing and forms the
physical basis for the speed of sound measurement (see Figure 1-1). Two
versions of Acoustic Sensor are available:
Chapter 1
Introduction
Standard Acoustic Sensor, for use with hydrogen or helium carrier gas at
flow rates up to 2000 sccm, or for carrier gases of any molecular weight at
flow rates up to 1000 sccm.
High Flow Acoustic Sensor, for use with nitrogen carrier gas or a higher
molecular weight carrier gas, at flow rates between 1000 and 2000 sccm.
An Interconnect Cable which connects the Sensor Control Unit and
Acoustic Sensor.
An optional 24 V(dc) Power Supply which provides power to the
Sensor Control Unit.

Composer Elite Operating Manual
CAUTION
2.1 Composer Elite Installation Guidelines
The requirements and recommendations in section 2.1.1, section 2.1.2, and
section 2.1.3 must be reviewed and understood before Composer Elite is installed
as described by section 2.2, Composer Elite Installation, on page 2-8.
2.1.1 Pressure, Temperature, and Tubing
2.1.1.1 Maximum Pressure
Reliable measurement of concentration to absolute pressures as low as 26.66 kPa
(200 Torr) requires relatively thin and flexible diaphragms to be used so that
sufficient acoustic energy may be transmitted.
There is a possibility that the diaphragms may destructively rupture if an absolute
pressure greater than 826 kPa (6200 Torr) is applied. A secondary containment
chamber is built into the Acoustic Sensor to prevent process gases from escaping
the Acoustic Sensor in the event of a diaphragm rupture.
Chapter 2
Installation
Do not connect the Acoustic Sensor to process tubing
that can exceed an absolute pressure of
826 kPa (6200 Torr). Exposing the Acoustic Sensor to
excess pressure may cause catastrophic diaphragm
failure or may stretch the diaphragms, requiring on-site
reference zeroing (see section 4.1.2 on page 4-1).
A certified rupture disk should be installed upstream of
PN 074-566-P1B
the Acoustic Sensor to limit any possible over-pressure
to less than 826 kPa (6200 Torr).
2 - 1
Composer Elite Operating Manual
2.1.1.2 Pressure and Tubing Size
The Composer Elite System is designed to operate with the gases in the Reactor's
process tubing at a pressure of 26.66 to 133.3 kPa (200 to 1000 Torr). The inner
diameter of the inlet and outlet tubes on the Standard and High Flow Acoustic
Sensors were designed to optimize performance at low pressures; however, the
Reactor’s process tubing may be of any appropriate size without degrading
Composer Elite performance.
2.1.1.3 Heated Process Tubing and Acoustic Sensor Temperatures
Operation of the Acoustic Sensor at a temperature slightly higher than the process
gas tubing will help prevent material from condensing inside the acoustic sensor.
INFICON recommends the following temperature settings:
The Temperature Setpoint 1 setting for the Acoustic Sensor's resonant
chamber temperature should be 5°C or more above ambient temperature.
See section 3.3.2.7, Sensor Parameters Screen, on page 3-12.
The Temperature Setpoint 2 setting for the Acoustic Sensor's inlet tube
temperature should be above the Temperature Setpoint 1 setting. Typically
start out with this temperature three degrees above Temperature Setpoint 1.
The inlet tube heater is designed to minimize zero point offset caused by large
flow rate changes. The optimal setting will depend on process conditions.
See section 3.3.2.7, Sensor Parameters Screen, on page 3-12.

PN 074-566-P1B
2.1.2 Grounding and Shielding
WARNING - Risk Of Electric Shock
CAUTION
2.1.2.1 Power Supply Grounding Requirement
The Composer Elite 24 V Power Supply must be
connected to a grounded socket outlet using a
three-conductor power cable with ground terminal.
The Composer Elite 24 V power supply (optional) is connected to ground through
a sealed three-conductor power cable, which must be plugged into a socket outlet
with a protective ground terminal. Extension cables must always have three
conductors including a protective ground terminal.
2.1.2.2 Earth Ground Requirement
Composer Elite Operating Manual
A low impedance and reliable earth ground is required for
proper performance of Composer Elite.
If local facilities engineering cannot provide a low impedance earth ground close to
Composer Elite, the following procedure is recommended.
1 Where soil conditions allow, drive two 3 m (10 ft.) copper clad steel rods into
the ground 2 m (6 ft.) apart.
2 Pour a copper sulfate or other salt solution around the rods to improve
the soil’s conductivity.
A near zero resistance measurement between the two rods indicates that a
desirable earth ground is established. In severe cases, it may take several
soakings of solution over several days to reach this condition.
PN 074-566-P1B
NOTE: Keep connections to this grounding network as short as possible. Most
noise transients contain significant power at high frequencies. A long path
adds to the ground circuit's inductance and thereby increases its
impedance at these frequencies.

2.1.2.3 Composer Elite System Grounding Requirement
The Sensor Control Unit and Acoustic Sensor must be
grounded for proper performance of Composer Elite.
The following grounding method is recommended:
1 Verify that the Reactor is connected to a good, reliable earth ground (refer to
section 2.1.2.2, Earth Ground Requirement, on page 2-3). Use a solid copper
strap, at least 0.08 cm (0.030 in.) thick by 2.5 cm (1 in.) wide, and as short as
practical, for the connection between Reactor and earth ground (see
Figure 2-1).
2 Use a solid copper strap, approximately 0.08 cm (0.030 in.) thick by
2.5 cm (1 in.) wide, and as short as practical, between the Sensor Control Unit
ground stud (see Figure 2-1) and the Reactor. A ring terminal soldered to the
ground strap will allow for a good connection to the ground stud and convenient
removal or installation.

2.1.2.4 Electrical Interference Reduction
When Composer Elite is integrated into a deposition system, each cable
connection is a potential path for electrical noise to be conducted to the Sensor
Control Unit or Acoustic Sensor. The possibility of external electrical interference
problems can be greatly reduced by adhering to the following guidelines:
Make certain the Sensor Control Unit and Acoustic Sensor are properly
grounded. (Refer to section 2.1.2.3, Composer Elite System Grounding
Requirement, on page 2-4.)
Make certain the Sensor Control Unit covers and option panels are in place and
secured with the provided fasteners.
Use shielded cable as short as practical for remote communications.
Avoid routing the Composer Elite Interconnect cable and communications
cable near areas that have the potential to generate high levels of electrical
interference. For example, large power supplies can be a source of large and
rapidly changing electromagnetic fields. Placing cables at least 30 cm (1 ft.)
from these problem areas can result in a significant reduction
of electrical interference.

2.1.3.1 Selecting The Acoustic Sensor Location
Locate the Acoustic Sensor at a point after the Dilution Flow gas is added and
before the Back Pressure Controller. (See Figure 2-2 on page 2-6.) This creates
the environment with the most stable pressure and flow conditions for best
Composer Elite stability. Positioning the Acoustic Sensor after the Dilution Flow
also simplifies calibration by making it easy to flow pure carrier gas through the
Acoustic Sensor to set the Reference Zero.
Figure 2-2 Basic integration with a reactor
2 - 6
The Acoustic Sensor may be installed in any orientation, however, INFICON
recommends the normal inlet and outlet tube convention (refer to Figure 2-2) be
followed. The inlet tube is substantially longer than the outlet tube to facilitate
temperature equalization. If the inlet and outlet tube connections are reversed,
there may be a small frequency or concentration offset when the total gas flow
through the sensor is varied.
Ventilation clearance is not required; however, the surface the Acoustic Sensor is
mounted to must be at least 5°C below Temperature Setpoint 1.
The dimension from inlet tube VCR-4 sealing surface to outlet tube VCR-4 sealing
surface is 124 mm (4.88 in.).
Acoustic Sensor installation or removal from process tubing requires side-to-side
or top-to-bottom clearance of 152.4 mm (6 in.) for wrench rotation.
Interconnect Cable installation or removal requires 76.2 mm (3 in.) clearance.
PN 074-566-P1B
Composer Elite Operating Manual
WARNING
The Interconnect Cable route should be planned to minimize external electrical
interference. (Refer to section 2.1.2.4, Electrical Interference Reduction, on page
2-5.)
2.1.3.2 Selecting The Sensor Control Unit Location
The Sensor Control Unit is designed for bench top operation or mounting in a
standard 48.26 cm (19 in.) rack using the optional Full Rack Extender
(PN 782-900-007). Ventilation is adequate when operating on a bench top or when
installed in a standard rack using the optional Full Rack Extender.
If the Sensor Control Unit will not be mounted in a
standard rack, select a location where the Sensor Control
Unit is protected against falling to prevent instrument
damage and personal injury.
Sensor Control Unit removal from a standard rack requires 30.5 cm (12 in.)
clearance in front of the rack.
Clearance of 7.62 cm (3 in.) is required at the rear of the Sensor Control Unit for
installation or removal of Interconnect, Power Supply, RS-232, and DeviceNet
cables.
Sensor Control Unit location should be selected to minimize the length of the
grounding strap. (Refer to section 2.1.2.3, Composer Elite System Grounding
Requirement, on page 2-4.)
Interconnect Cable and communication cable routes should be planned to
minimize external electrical interference. (Refer to section 2.1.2.4, Electrical
Interference Reduction, on page 2-5.)

3.2 Calibration
Calibration obtains the exact frequency (speed of sound) for the carrier gas (or one
component of a mixture) for specific Composer Elite System operating conditions.
Calibration determines Reference Zero.
For many applications, Factory Zero is sufficient to provide the needed levels of
accuracy and reproducibility. Refer to section 4.1.3, How is Performance Affected
if I Use the Factory (Reference) Zero Value?, on page 4-2.
3.2.1 Frequency of Calibration
Applications requiring the highest degree of reproducibility should be calibrated
daily. Experience will determine if less frequent calibrations are appropriate. See:

4.1 Advice and Tips
The following paragraphs review many common questions encountered during
setup and operation.
4.1.1 What is the Required Warm Up Time?
Once the setpoint for the Acoustic Sensor’s temperature is altered, it will take up to
thirty minutes for a single Acoustic Sensor’s temperature to settle around the
operating point. It may take even more time if the temperature setpoint is lowered
and is close to the ambient temperature (refer to section 2.1.1.3, Heated Process
Tubing and Acoustic Sensor Temperatures, on page 2-2).
Once the setpoint temperature is reached, Composer Elite is ready to provide data.
It is our experience that because of the relatively low thermal conductivity of the
materials used to construct the Resonant Chamber, even after an hour there is still
some small potential to further reduce temperature induced speed of sound
measurement errors. It is easy to reset the Reference Zero frequency and
eliminate these effects (refer to section 3.2, Calibration, on page 3-2).
Chapter 4
Applications Guide
It is also expected that the Acoustic Sensor will always be operating, minimizing
day-to-day variations because any long term thermal settling complications will be
absent. If the ambient temperature changes, there may be some slight variation on
the temperature of the Resonant Chamber as the effective thermal load changes.
This can be ignored except for the most precise measurements and over the most
extreme temperature swings.
4.1.2 When and How Often to Set the Reference Zero
PN 074-566-P1B
Normal operation will be enhanced by daily Calibration to set Reference Zero (refer
to section 3.2, Calibration, on page 3-2). This mitigates any effects of slight
variations in day-to-day process tubing pressure and atmospheric pressure
changes. If the frequency of the Reference Zero is recorded every day, a record of
Composer Elite performance is generated. This makes it easy to determine if a
mistake has been made due to careless procedure by comparison to the previously
recorded values. It would be unusual for Composer Elite’s daily Reference Zero
frequency to vary by more than about 0.2 Hz for nitrogen and 0.8 Hz for hydrogen.
Calibration should be immediately performed any time the pressure, flow rate or
any other Composer Elite subsystem such as a Mass Flow Controller, Back
Pressure Controller or pressure gauge is changed — even if it is the same type and
uses the same settings.
4 - 1
Composer Elite Operating Manual
CAUTION
The correct (user set) Reference Zero is retained until a new Reference Zero is
established, the Setpoint Temperature is changed or new carrier gas
parameters are entered.
NOTE: STEADY and AT TEMP must be visible when completing the Calibration
process. This indicates the measurement conditions are stable and a
relative equilibrium has been reached. It sometimes takes many minutes
for the light (low molecular weight) carrier gas to clean the Resonant
Chamber of any residual Precursor or other heavy gases. Remember that
some gases may also absorb on the Resonant Chamber’s walls and are
slowly released, further extending the time to reach pure carrier gas as
indicated by stable frequency.
Setting Zero Reference before the Resonant Chamber is
completely purged of precursor gas will result in an
offset and scaling error in the measured concentration.
See section 4.1.10 on page 4-8.
4.1.3 How is Performance Affected if I Use the Factory (Reference) Zero Value?
While it is most accurate to reset Reference Zero daily, excellent results can be
obtained for many processes by using the Factory Zero value for Reference Zero.
While the exact loss of reproducibility is hard to predict, it is reasonable that it will
be about two to four times worse than the specified value when monitored over
extended periods of time. This may be acceptable, and convenient, for the process.
Alternating between the Factory Zero and carefully setting the Reference Zero
occasionally will not be productive. It would be better to extend the interval between
reestablishing the Reference Zero than to alternate. An example of long term
stability is shown in section 4.1.9 on page 4-7.

4.1.4 What To Do when the Specific Heat Ratio for a Gas is Unknown
Quantitative accuracy for an acoustic measurement technique partially depends on
accurate knowledge of the Specific Heat Ratio,
While this ratio is known for many pure common gases, little information is
available on many of the complex Precursor molecules. The information currently
available is given in Table B-1 on page B-1. Even without exact knowledge of the
Specific Heat Ratio, useful information and reliable operation can still be obtained.
The Specific Heat Ratio of gases is a parameter that does not have a large range,
it is confined to a range of about 1.1 to 1.7 for almost every known gas.
Consequently, using the wrong Specific Heat Ratio will not make a significant error
in most cases. It is also possible to make intelligent guesses about unknown gases
using the value of the Specific Heat Ratio for a similar gas. It is almost always more
accurate to overestimate the Specific Heat Ratio than to underestimate by the
same amount; see Appendix B and Figure 4-1. Consider also that in production,
accuracy is not as important as the reproducibility. As long as the Specific Heat
Ratio is not changed, Composer Elite will produce similar results, day after day.
NOTE: Long term use of Composer Elite with some of the materials listed in
Appendix B may not be possible.

4.1.5 What is the Ideal Operating Environment?
In an ideal operating environment, parameters that influence the concentration
measurement do not change. Most Reactors can be configured so that the
pressure and flow through the Acoustic Sensor are held constant by independent
controllers. The precursor’s fluence into the Reactor can be maintained or changed
without altering the total flow and pressure through the Acoustic Sensor. This is
considered good practice for Reactor design.
Leave the Composer Elite System on at all times— always ready to immediately
function with best accuracy. We have not seen deterioration through continuous
use. Since all Reactors are in environmentally controlled rooms, the small
influences due to ambient temperature changes are of no concern.
4.1.6 What is the Effect of Pressure Variation?
Because not all mixtures are purely ideal and the use of diaphragms to separate
the toxic and corrosive gases from the Exciting and Receiving microphones is
required, Composer Elite displays a small influence from pressure changes. The
effects of pressure variation on concentration are shown in Figure 4-2.

4.1.7 What is the Effect of Flow Variation?
There is virtually no flow induced effect on concentration measurement in the
Composer Elite System except at the highest flow rates, see Figure 4-3, the
pressure drop across the Acoustic Sensor is about 12 Torr [1.60 kPa] at 2000 sccm
for the Standard sensor or 6 Torr [0.80 kPa] for the High Flow sensor.
HINT: Large variations in flow rate will cause a shift in the zero concentration
point. To minimize zero shift due to flow rate change, carefully set the inlet
tubing heater temperature (Temperature Setpoint 2). The default value for
Temperature Setpoint 2 is 3 degrees higher than Temperature Setpoint 1.
Adjusting the Temperature Setpoint 2 value slightly might be necessary
depending on your process requirements.

PN 074-566-P1B
4.1.8 How Does This Instrumental Method Differ from Measuring the Speed of Sound by Time of Flight?
The use of a low frequency Resonant Chamber has significant advantages over
Time of Flight (TOF) methods. It allows the constructive build up of energy within
the Resonant Chamber. Plus, sound transmission in hydrogen at low frequency is
more efficient than at high frequency. This enhances the instrument’s ability to
measure concentration in hydrogen mixtures at lower pressures. Finally, the
careful intelligent manipulation of the applied frequency around the resonant
amplitude peak allows even greater precision in the determination of the speed of

sound. The resonant method does not lose accuracy because of uncertainty of
guessing when the center of a low energy acoustic pulse packet precisely leaves
the Sender and reaches the Receiver. See Figure 4-4.
For a TOF instrument to achieve resolution equivalent to Composer Elite
(1 part in 50,000), it must achieve time measurement precision of 3 nanoseconds.
This resolution is achievable for sophisticated instruments measuring photons or
particles, but is approximately forty times better than the resolution possible on the
poorly defined 15 kHz ultrasonic wave pulse in hydrogen. One wavelength of a
15 kHz tone is 0.0856 m, almost one half the length of a 0.2 m path length
instrument.
4.1.8.1 Calculation Example
The time interval for an acoustic pulse to travel 0.2 meters in hydrogen is computed
as follows (see equation [1] and Figure 4-4)
NOTE: The speed of sound in hydrogen is 1284 meters/second.
[1]
In order to achieve equivalent resolution to the Composer Elite resonant technique,
the TOF instrument’s ability to measure the pulse must be 1/50,000 of the transit
time, or: 1.56 E-4 (1/50,000) = 3.12 E-9 seconds

4.1.9 What is the Long Term Stability of this Measurement System?
There does not appear to be any trend that might lead to any unexpected wear or
degradation with time. This data is not corrected for zero offsets due to atmospheric
pressure variations over the test period.
Using R134a in nitrogen as a test (R134a is similar in molecular weight to some
common metal organic precursor gases), the chart shown in Figure 4-5 shows
stability of +/- 5 ppm over 112 hours, even as the ambient temperature
varies by 3°C. This is equivalent to <1 ppm trimethylIndium in hydrogen.

4.1.10 What Happens if the Reference Zero is Improperly Set?
If the Reference Zero is set when the conditions are wrong, i.e., not completely
purged of precursor gas:
1 A permanent concentration offset is introduced equal to the residual precursor
concentration when the new Reference Zero is applied. This is not corrected
until a proper Reference Zero is performed.
2 The sensitivity is altered, leading to an error proportional to the concentration.

4.1.11 How to Sample Flow with a Composer Elite
When the flow through a process pipe exceeds the Acoustic Sensor’s 2000 sccm
limit, sampling of the process is required. In our experience, bypassing some of the
process gas through the Acoustic Sensor can compromise Composer Elite
precision, long term accuracy and add noise due to pressure and flow fluctuations.
Our recommendation is to “buffer” the flow through the Acoustic Sensor by adding
a Mass Flow Controller (MFC) upstream of the Acoustic Sensor in the sample
tubing. This device will stabilize the flow and in most cases restore Composer Elite
full measurement capability. In some extreme cases it may be necessary to also
add downstream buffering with a Back Pressure Controller. Try to maintain at least
200 Torr [26.66 kPa] in the Acoustic Sensor for best operation. It may be necessary
to slightly restrict the process tubing in order to induce flow through the sample
tube. See Figure 4-7.
An added benefit of adding the MFC to the sample tube is that flow through the
Acoustic Sensor is made visible and easily verified.

Remote Communications
5.1 Introduction
Composer Elite supports RS-232C and DeviceNet communications, and may be
remotely controlled, programmed or interrogated. This is accomplished through
remote communications and the use of a remote command set. Composer Elite will
respond to messages that contain these commands. It will accept and operate one
message at a time. It will respond to each command by carrying out valid
operations and/or returning a message to the sender. A host/server relationship is
established in remote communications. Composer Elite, as server, responds to the
remote host’s commands.
5.2 General Type Definitions for Remote Communications
General Type Definitions
<Float> = 4 byte, single precision ANSII standard floating point, low to high
<String> = Variable length, null terminated ASCII characters
<Byte> = 1 Byte
<Encode> = 4 Byte, low to high
<Short> = 2 Bytes, low to high
<Integer> = 4 Bytes, low to high
NOTE: All data elements larger than a byte are in little-endian form, both those
sent and returned.
PN 074-566-P1B
5.3 RS-232 Communications
For RS-232 communications, an industry standard 9-pin D-sub-miniature
connector is required to connect to Composer Elite. See Figure 5-1 and Table 5-1.
Both the host and server must have the same form of communications equipment
and complementary set up. For serial communications, baud rates must match and
so must the data word format. Hardware handshaking is not supported.
The word format for bit serial lines (RS-232C) is comprised of ten signal bits:
eight data bits, one start bit, one stop bit and no parity.
The eight data bits comprise a byte of information or character whose ASCII value
ranges from 0 to 255.
The length of the cable is limited to 15.2 m (50 ft.).
5 - 1
Composer Elite Operating Manual
CAUTION

9
Only serial communications baud rate of 115,200 is supported.
The communications interface operates using the DCE (Data Communications
Equipment) configuration.
NOTE: Some RS-232 hardware/software combinations may occasionally
cause a command to not be recognized by Composer Elite.
Consequently, all communications should include an automatic retry
procedure if a response is not received within three seconds.
RS-232 uses single-ended signaling with all signals sharing
a common ground, making it susceptible to cross-talk and
noise if the RS-232 cable is not properly shielded and not
routed away from sources of noise. A very high data rate can
overwhelm the internal buffers of the computer, resulting in
data loss. Computer configuration (such as a power setting
that allows the computer to sleep during a run) can cause
data loss. Data loss can occur due to issues inherent to the
Windows operating system, including the diversion of
computer resources when Windows Automatic Update or
antivirus software checks for updates on the Internet.

5.4 DeviceNet Communications
CAUTION
For DeviceNet Messaging, the transmit/receive message count field is used by the
process transmitting the message to indicate that data is available to read and
process.
The application will populate the Composer Elite command field with the data to be
transmitted to Composer Elite and increment the Transmit Message Count field.
This will indicate to Composer Elite that there is a command ready to be
processed.
Composer Elite constantly monitors the value in the Transmit Message Count
field. When Composer Elite detects a change in the value of the count field, it will
process the command and put the response in the Composer Elite Response field
and increment the Receive Message Count value.
The application will periodically read the Receive Message Count field for a
change in the count. When a count is detected, this indicates to the application that
Composer Elite has completed processing the command sent and a response is in
the Composer Elite Response field.
Upon initialization, the application must read the Receive Message Count field
and use it as its initial receive/transmit count values. The transmit message count
must be given ahead of the desired command message. Responses, on
DeviceNet, will also be preceded by a receive byte count.
Composer Elite Operating Manual
NOTE: DeviceNet communications used with Composer Elite Multi-Sensor
Software must be used with a Beckhoff FC5201 DeviceNet computer
Interface card.
The DeviceNet cable requires 24 volts. This voltage is not supplied by the
Sensor Control Unit. If the Beckhoff FC5201 DeviceNet computer interface
card does not detect 24 volts, it will not work and flag an error.
If remote communications are used, any DeviceNet device will be suitable
for DeviceNet communications.
PN 074-566-P1B
DeviceNet communications over a single bus can allow data
to be inadvertently sent and received simultaneously,
resulting in the loss of that particular data set (this is not an
issue when using the Composer Elite’s full-duplex RS-232).
A very high data rate can overwhelm the internal buffers of
the computer, resulting in data loss. Computer configuration
(such as a power setting that allows the computer to sleep
during a run) can cause data loss. Data loss can occur due
to issues inherent to the Windows operating system,
including the diversion of computer resources when
Windows Automatic Update or antivirus software checks for
updates on the Internet.

5.4.1.8 I/O Data Format Object (64h)
The I/O Data Format Object is a vendor specific object used to determine how the
contents of the Assembly Object buffers are formatted and used. The Composer
Elite Output (CE OUT) and the Composer Elite Input (CE IN) can be used to
exchange INFICON messages. Alternatively, the Composer Elite Output (CE OUT)
can be used to cache a predefined set of data values.
Composer Elite Operating Manual
Get UINT 04h
Per the Composer Elite Cache Data Sets (see section 5.4.2, DeviceNet Data Sets,
on page 5-12), all INFICON data sets are formatted per these byte tables and
accessed via the Assembly Object (04h, Instance 96h). The Composer Elite will
continuously update these data values as the values change. A change indicator
in the form of a count field will be maintained to indicate when the values may have
changed. Also, an update in progress indicator is given to indicate when a data set
could be partially updated. The data set currently published is reported to help the
host correctly interpret the data present.
NOTE: The data set functionality is only available when a Polled, COS, Cyclic or
Bit Strobe connection is detected.

After a power cycle, Composer Elite will default to expecting and responding to
INFICON messages. To instruct Composer Elite to cache data in CE OUT instead,
in the host computer set the I/O Data Set attribute to a non-zero value. The value
will specify to Composer Elite which data set to cache. This value can be changed.
When Composer Elite is caching data to CE OUT, CE IN is not used.

5.4.3 DeviceNet INFICON Messaging
All information exchanges are formatted and accessed via the Assembly Object
(04h, Instances 64h, 96h). Transactions with Composer Elite follow the form of
Host setting the Assembly Object data field (CE IN data) following the content
below (starting at section 5.4.3) and when the change indicator (Transmit / Receive
Message Count field) changes the response content is ready to be read out. Each
new command (CE IN data) must update the Transmit / Receive Message Count
field to signal the Composer Elite communications process that a new command is
pending.
NOTE: The body of the CE IN and CE OUT data block (bytes 2 … n) after the
PN 074-566-P1B
Transmit / Receive Message Count field are identical to messages
exchanged over RS-232.
5.5 Message Format
Standard message protocol serves as a structure for the contained command or
response information. It also can provide a level of acknowledgment between the
host and server and a mechanism for verifying the information content.
5 - 21
Composer Elite Operating Manual
5.5.1 Command
This section describes the command format.
See section 5.6, Communication Commands, on page 5-27 for details on specific
command IDs.
The message received by Composer Elite contains a data packet preceded by a
length and terminated by a checksum.
Composer Elite will always send a response to any command it receives.
5.5.1.1 Command Packet (Host to Composer Elite Message)
<Length><Message><Checksum>
Length . . . . . . . . . . . . . . . . . . . . . . . 2 bytes Low / High (not including checksum
or length bytes). Numeric value representing
the number of characters in the command. In
order of transmission, the low byte will
precede the high byte. Normally, the number
for characters will be less than 9. In this case,
the low byte will contain the character count
while the high byte will have zero value.
Message . . . . . . . . . . . . . . . . . . . . . <Command>
Checksum . . . . . . . . . . . . . . . . . . . . 1 byte, sum, modulo 256, of all bytes, not
5.5.2 Response
This section describes the response format that is returned in the data field of the
response message. See section 5.6, Communication Commands, on page 5-27 for
more details on responses. The message sent by Composer Elite contains a data
packet preceded by a length and terminated by a checksum. See section 5.5.2.1
for a detailed description of the received message structure.
If a command generates an error in response, an error code is returned (see
section 5.5.2.2) in the Response Message and the SS bit in the status byte (see
Table 5-18 on page 5-24) is set to 0. The SS bit is set to 1 indicating successful
completion of the received command.
including length. Modulo 256 is the numeric
value from 0 to 255 representing the modulo
256 remainder of the sum of the values of the
ASCII codes that comprise the command.

5.5.2.2 Communication Error Codes
If there was an error detected with the command sent to Composer Elite, the
response message will have the MSB of the status byte (SS bit) cleared (see Table
5-18 on page 5-24). The data portion of the message will be one byte long and will
be one of the following:
3 (0x03) . . . . Message length is zero*
10 (0x0A) . . . Invalid sensor number
11 (0x0B) . . . Invalid program number
