Use the Create Chromatograph button to manually create new FMS Chromatograph Node configurations. When creating new device Nodes, keep in mind the distinction between meters and chromatographs. A chromatograph must return gas quality history. A meter must return gas measurement history, and may optionally return gas quality history.
CygNet Measurement also provides a system command that can automatically create FMS device Nodes in your system. See the following topic for more information about this option.
See Viewing and Editing Chromatograph Node Properties for more information about accessing properties for Chromatograph Nodes that have already been created.
To create a new Chromatograph Node, Open the Nodes menu in FMS Explorer, and then click Create Chromatograph. A series of dialog boxes will appear.
Note: These dialog boxes are the same as dialog boxes that open when you click New FMS Chromatograph on the FMS page of a remote device in the Device Definition Service (DDS), and the same dialog boxes that open when you View Node properties from many context menus in FMS Explorer and the FMS service in CygNet Explorer.
The following tables list and describe property fields found on the Create Chromatograph dialog boxes.
To create a new Chromatograph Node, first define it in the Device Definition Service (DDS).
Enter the following device definition properties to define the new chromatograph device.
| Property | Description |
|---|---|
|
Node ID |
The system-assigned Node ID for the Chromatograph Node. When creating new Chromatograph Nodes, this will indicate NEW. |
|
Enabled |
The Enabled check box indicates whether the chromatograph is enabled or not. An unchecked box does not mean the chromatograph is deleted; all chromatograph settings are saved until you choose to enable it. Default value is Enabled. |
|
Device name |
Type in the name for the Chromatograph Node. Valid characters (maximum of 20) are as follows. A-Z, a-z, 0-9, . (period), #, $, &, (, ), +, -, \, /, :, <, >, =, @, [, ], ^, {, }, _ (underscore), !, ~ (tilde). Spaces are acceptable, when they are not leading or trailing. This parameter is required. |
|
Description |
Type in a free-form Description for the chromatograph. This parameter is optional. |
|
Security application |
Enter the security application used to validate users of the Node. Use this setting to control user access, for example, to only give certain users access to particular Chromatograph Nodes. See FMS Security for more information. This parameter is optional. |
|
Sort priority |
Type in the Sort priority number to assign to the Chromatograph Node. The priority number assigned places it within a manually sortable list. Higher numbers place a Node higher up on a list. Default value is 0. This parameter is optional. |
| Data source options | |
|
Data source |
Select the data source for the chromatograph from the drop-down menu. Options are as follows.
|
|
Polling UIS |
If Polling Engine is your selected Data Source, click … to select the polling UIS for the chromatograph. |
|
Polling facility |
If Polling Engine is your selected Data Source, click … to select the facility polling for the chromatograph. Note: The list provided contains all linked facilities that belong to the FMS Configuration or FMS Legacy Configuration data group corresponding to your data source selection. |
|
Note: The Unit set override parameter is optional. It is provided to give you the ability to override units in cases where GMR data coming into FMS (via the FMS Toolbox) may contain values in units other than the assumed GMR units. In such a case, use this parameter to define the unit set to use instead, and the FMS system will apply the specified unit set to the incoming GMR data See GMR Data Items Units for more information. If used, select a unit set for the system to apply to GMR data, from the options in the drop-down menu. Options in the drop-down menu are populated by the enabled read-only unit sets configured in your system. You may have to create the applicable unit set first. See Configuring Unit Set Definitions for more information. |

Device install date (Device time) |
Select the date and time of the installation of the chromatograph using the date and time selectors. When no user-entered value is provided, the default install date value is 36 days prior to Node creation, at 12:00:00 AM. Example The Install Date is the date and time the chromatograph began collecting data. Notes: The Request Missing Data or Request New Data commands will not request data prior to the device install date. Edits to this property can only be applied for the entire span of the Node. An error message will appear if you try to edit this value for a partial span. |
|
Use job schedule start date |
Note: This parameter defines a date used by the Schedule Jobs command for CygNet Dispatch. For more information about the CygNet Dispatch product, contact your Account Manager or CygNet Sales. When using CygNet Dispatch, optionally set this value to define the first possible start date that can be used for job occurrences associated with this Node, when automatically scheduling jobs via the Schedule Jobs command. If used, click the check box to access the date selector, and specify the earliest date from which CygNet Dispatch jobs for this Node can be scheduled. When no user-entered value is provided, the default value is the Device install date. See Schedule Jobs for more information. |
| Supported data
Note: Each of the following properties is read-only once the corresponding data type has been collected for the Node. The properties can only be edited if the device has not yet received the corresponding data, since Node properties must be consistent across their time continuum. Trying to edit a Supported data property, for a device which has already received that type of data, will produce a service error. |
|
|
