The Device page is used to configure general information about the device such as the Line Pack device name, description, transaction logging, and device security. You can also execute the UIS command (CALCULATE or VCALCULATE) to perform a Line Pack or Mass Balance calculation from this page by clicking Execute Calculation.

The properties for each section of this page are described below. See the following subsections below for more information:
| Property | Description |
|---|---|
|
Device ID |
The unique identifier of an instance for this device. This free-form name must be unique in the DDS and the FAC. That is, it must be a name not used by any other communication device, import/export device, remote device, or facility. Valid characters are A-Z, 0-9, dash (-), underscore (_), and tilde (~). No spaces are allowed. 20 character maximum. Note: Tilde (~) is a valid character for both devices and facilities, but its use is not recommended. |
|
Enable device |
Check to enable or disable the device. The default setting is disabled. The device will automatically disable if an invalid configuration is detected. The device can be re-enabled after the invalid configuration is fixed. |
|
Description |
A free-form description of the device. 32 character maximum. |
Each UIS command executed by the Line Pack driver will generate a single transaction log. Within that single log entry will be the results of each pack segment calculation.
| Property | Description |
|---|---|
|
Max log records |
The maximum number of transaction history records that can be maintained for the device. Each UIS command executed by the device will generate a single transaction log. If the device is setup for active monitoring, one transaction will be created whenever a new file is detected. If multiple files are detected at the same time, it will still result in one transaction. |
|
Log warnings |
Check this box to log the occurrence of all warnings. |
|
View transaction log |
Click to view transaction and status log entries. |
The security fields define the application and event that controls which user(s) can edit and perform calculation. See Component-Level Security - Text Import Device for more information about component-level security.
| Property | Description |
|---|---|
|
Application |
Defines the ACS security application name used to validate the users of this device. See Applications, Events, Permissions. |
|
Event |
Defines the ACS security event used to validate users of this device. Click … to select the security event. See Applications, Events, Permissions. |
Click Execute calculation to manually initiate a Line Pack or Mass Balance calculation. Options include:
Execute a calculation by sending a UIS command of the type CALCULATE ("Calculate") to the Line Pack driver. A second UIS command VCALCULATE ("Validate and calculate") can be issued to first validate segments, facilities, and points, and then perform the Line Pack and Mass Balance calculations. The recommended configuration is to initiate the CALCULATE command, and then if you know there are changes to the system, initiate the VCALCULATE command, and then repeat once an hour to make sure the Line Pack driver has the most up-to-date database entities in its cache.
These UIS commands can be scheduled via the MSS or executed directly on the Device page of the device editor.
