Trend Data Collection
Trending is a function that records point data over time. Trend data is either collected
when the current point value changes by a specified amount (the trend COV limit), or
point values are recorded after the system waits a specific amount of time and then the
process is repeated.
Trend data can be uploaded from the field panel to the Insight workstation for storage
and reporting, and the data can be converted to several spreadsheet formats for
further analysis and reporting.
User Access and Privileges
A user issues commands or requests to the PXC Compact Series using an operator
terminal and the operator interface program that resides in the PXC Compact Series.
The operations that a particular user can perform depend on the access level assigned
to each field panel function in their user account.
User accounts are used to manage access and security for field panels on a specified
Automation Level Network (ALN). By creating individual accounts, a system
administrator can control each user’s access to objects and functions residing in field
panels on a specified ALN.
Specifically, a system administrator can perform the following tasks:
● Define the users that can access an ALN
● Assign access to access groups
● Assign privileges to field panel functions residing on an ALN
Controlling User Access to Field Panel Functions
The following four access levels can be assigned to any field panel function for any
user.
● No Access – Users cannot see the function.
● Read Only – Users can only view the value or status of objects.
● Command – Users can command or display the value or status of objects.
● Edit – Users can add, delete, command, modify, and view objects.
Example
If a user has a Command access level for the Point Editing function, then only the
functionality required to command a point is available to them. They do not see or have
access to the prompts required to add, modify, or delete a point definition.
For more information on user accounts and privileges, see the APOGEE P2 ALN Field
Panel User's Manual (125-3019) or the APOGEE BACnet ALN Field Panel User's
Manual (125-3020) (125-3019 or 125-3020).
