2.8 Saving a Device File
At times it may be necessary to save the current device configuration. These should be stored for
future reference, or in the case an Envent Engineering technician requests the device file for
diagnostic purposes.
1. Connect to the device using one of the methods described in Section 3 of this manual. Ensure
that the device is connected and has been “read” and all parameters are sucessfully in the
software. The save function only saves the current “read” state of the analyzer.
2. Click the File menu and click “Save As…”, save the device file to a known location and give the
file a descriptive name. The recommended file format is as follows: “YYYY-MM-DD –
[SN].device”
2.9 Uploading a Device file to the Analyzer
It may be required to upload an older (or preconfigured) device file to the analyzer.
1. Connect to the device using one of the methods described in Section 3 of this manual. Ensure
that the device is connected and has been “read” and all parameters are sucessfully in the
software.
2. “Close” the current configuration by navigating to File > Close. The user can also right-click the
device tab (below the menu bar) and click “Close”. Closing the device file this way maintains
the connection to the device.
3. Open the required configuration file by navigating to File > Open. Select the file needed to be
opened.
4. Write the opened configuration to the analyzer by clicking the write icon ( ).
2.10 Changing System Units
Click the View > Preferences menu. This dialogue menu will allow the user to change the time units as
well as the temperature and pressure units displayed in the ICE software. The recommended time
units to use are “ss.ss”.

Envent Engineering Ltd – 131S & 132S Software Manual – Revision 0 Page 8
2.11 Using the System Variables (Blue Menu)
System variables are often used for configuration, ranging from setting up alarms to configuring
modbus or the display of the analyzer. When a field, which can accept system variables, is opened the
system variables menu will become visible. It is easily identified by its blue color.
Each system variable can be “dragged” into a field which accepts it. Some fields (such as modbus
configuration) allow system variables to be double-clicked or even entire folders to be dragged.
1. Identify the variable that is needed and locate it in the folders.
2. Drag the variable into the required field (see screenshot below). To remove variables, the
variable can often be deleted by highlighting it and pressing the “Delete” key on the
keyboard. In the example below, a Discrete Input “Low He” was dragged to create a new
alarm point.
Please note: For some variables we must use the “Output Value” of the variable. An example may be
the oven temperature. The location “Analog Inputs > Oven Temp” is the
configuration of the oven
temperature input and not the actual variable. For this example, the correct variable would be: “GC
Control > Analog Input > Oven Temp > Output Value”.
Please contact Envent Engineering Ltd. for assistance if required.

3.0 Connection Interfaces
3.1 Connection Via USB
The model 131S/132S gas chromatograph is supplied with a USB-Mini Type “B” connection interface.
This interface will be located on the top of the GC below the display (on the model 132S GC) or
underneath the explosion proof cap below the display (on the model 131S GC).
Ensure that the driver is installed properly; if the driver has been installed properly, the USB device
should show as a comm port in the device manager of the operating system. In Windows 7, 8, or 10 the
device manager can be found by navigating to the system’s control panel. For assistance with
installing the USB driver, contact Envent Support.
1. Connect the USB cable from the PC to the gas chromatograph’s interface.
2. In Envent ICE click the connection globe on the menu bar ( ), select “USB-Speed” and the
correct communications port (in the screenshot below, COM7 was the selected port).
3. Click the read button ( ) and monitor the connection bar at the bottom of the software’s
interface. The connection bar should indicate which port is open as well as a progress bar
indicating read progress. Once the connection bar has concluded then the software has
successfully read the parameters from the device.

Envent Engineering Ltd – 131S & 132S Software Manual – Revision 0 Page 10
3.2 Connection Via Ethernet
The model 131S/132S gas chromatograph is supplied with an Ethernet interface card which can be
used for connection via the Envent ICE Software or for telemetry purposes via modbus. The
connection interface port on the ethernet card is a standard 8-pin RJ45 Ethernet connection. All 8 pins
are required for communication; thus, a standard Category 5 (or greater) cable is recommended.
A connection can be established directly connected to the analyzer, or through a network or sub-
network. The host PC and Envent Analyzer must be on the same sub-network to communicate. The
default connection parameters are as follows:
IP Address: 192.168.1.105
Subnet Mask:
255.255.255.0
Gateway:
192.168.1.1
Host Name:
(Typically SN of the board)
If the default settings are lost, please contact Envent Support for instructions on retrieving the
settings.
1. Connect the Ethernet cable from the PC to the gas chromatograph’s interface, or connect to
the same network as the gas chromatograph. Ensure that the PC is in the same sub-network
range as the gas chromatograph.
2. In Envent ICE click the Network menu and select “Scan Network”, or click “Add New…” if the
network parameters are already known. After a successful scan, the Network menu will
display all Envent Analyzers currently connected to the network.

Envent Engineering Ltd – 131S & 132S Software Manual – Revision 0 Page 11
3. Click the connection globe on the menu bar ( ), select the correct device (please note: the
devices in the screenshot may appear different on the user’s machine)(the speed selection at
the top of this interface does not matter).
4. Click the read button ( ) and monitor the connection bar at the bottom of the software’s
interface. The connection bar should indicate which port is open as well as a progress bar
indicating read progress. Once the connection bar has concluded then the software has
successfully read the parameters from the device.

Envent Engineering Ltd – 131S & 132S Software Manual – Revision 0 Page 12
3.3 Configuration of the Ethernet Interface
Envent ICE has a built-in system for configuration of the ethernet interface card. This configuration
should be done with the PC directly connected to the interface card and not through a network
switch, if possible.
1. Determine the sub-network to which the analyzer is connected, ensure the user’s PC is on the
same network – even if the device is directly connected.
2. Refer to the previous section to “scan” the network and find the analyzer on the network.
3. In the Network menu, point at the device using the mouse cursor and select the “Edit…”
option.
4. A dialogue menu will open, the new parameters of the network interface card can be
programmed here, once complete click the “Send Changes” button, this will alter the
configuration of the card.
5. Confirm that the change worked by altering the user’s PC Network configuration to match the
analyzer and use ICE to “scan” the network (refer to the previous section).

Envent Engineering Ltd – 131S & 132S Software Manual – Revision 0 Page 13
4.0 Device Configuration
Before modifying the factory configuration file, make sure to save it on the
user’s computer first for future retrieval. If the factory configuration file is
lost or modified without saving it, a copy is kept in the USB flash drive given
with the analyzer. Envent Engineering Ltd can also provide a copy. To save
the configuration file, go to File > Save or Save as.
Make the appropriate changes on the factory configuration file through the
ICE software. When changes are made, they need to be uploaded to the
analyzer to overwrite what is currently on it. Click on the ''Write button''
() and wait until the new configuration is uploaded successfully.
Note that the gas chromatograph relies on parameterization for correct analytical operation.
Adjusting values without a proper understanding of their function can have consequences including,
but not limited to, loss of measurement; damage to analytical components; and/or injury or loss of life
to operators.
Make sure to read, and understand, the contents of this manual fully and consult Envent Engineering
Ltd. if there are any concerns or doubts to the operation, maintenance, or parameterization of the gas
chromatograph analyzer. This section will use the following symbols, read, and understand their
purposes.
This symbol indicates that the operation, or parameter change, may cause damage to
the analytical components, or inadvertently create a potentially dangerous environment
for the operator.
This symbol indicates that the operation, or parameter change, may cause changes in
analysis, measurement, and/or outputted values or results.
This symbol indicates that there is a piece of information the operator should know prior
to continuing.

Inputs
Discrete Inputs
There are 4 discrete inputs available in the gas chromatograph, with an optional 8
telemetry “soft” points. DI 1 to 4 correspond with the discrete input channels on
the main board. These inputs are programmed to configure alarm points or
switching points. The below table describes the configuration of the discrete
inputs.
IO Name
Input the name of the DI (for example: “Low He”)
Active State
Closed: The DI looks for when the signal is “shorted” and
outputs a “1” indicating the alarm state
Open: The DI looks for when the signal is “open” and outputs a
“1” indicating the alarm state
Analog Inputs
Analog inputs are critical to the functionality of the gas chromatograph and
should not be adjusted by the end-user. Adjusting the analog input parameters
can have serious consequences involving the analytical sensor(s) or the analytical
oven and its internals. For assistance with analog inputs, contact Envent
Engineering Ltd.
