Notes
|
Name
|
You can assign a Name to each input which appears on the face of the microblock that is used as the name of the BACnet object. You can use any characters (including spaces) in this field, except for the " character.
|
Object Instance
|
The Object Instance number can be defined in the microblock dialog box or on the Properties page. The Object Instance should be the instance number of the BACnet object you wish to link to.
If two BACnet Analog Inputs in the same device have the same instance number, other BACnet devices may communicate with the wrong microblock. The Object Instance is in the range of 0 to 4,194,303. An instance number of 0 prevents the microblock from being able to communicate with other BACnet devices but does not affect the microblock's operation within the control program. As the NULL string is not accepted, it will generate an appropriate property error.
|
Alarm Category
|
WebCTRL uses the Alarm Category to determine which reporting actions to execute when it receives an alarm. You can also add custom Alarm Categories in WebCTRL.
|
Alarm Template
|
The Alarm Template is a template configured in WebCTRL to specify how to display alarm information. It includes many options such as displaying short and long text, and options for requiring operator acknowledgement of alarms. You can also add custom Alarm Templates in WebCTRL.
|
RefName
|
Use the default reference name unless you want a more descriptive name for this microblock for graphics, source tree rules, or network links. All reference names in a control program must be unique.
|
Show Property Page Text on:
|
Use Show Property Page Text on: to show or hide Properties page information for the microblock. Select Large Screens to display the information as a WebCTRL Server page. The Small Screens option is for a future release of WebCTRL. You can still view the Properties page for the point by clicking it in the Geo or Net tree.
|
Description
|
In the Local Values section, Description is the BACnet visible description property that may contain any items that you choose. The Units value is a BACnet units number. It indicates what unit the value is measured in. To make a selection that is not preconfigured, in most cases you can type your own value in the left field. Although the units can be read directly from the BACnet object, to avoid generating network traffic it is preferable to set it from the microblock.
NOTE Select the characteristics and capabilities of BACnet properties on the BACnet Analog Input Display Object dialog box. Detailed information is available in the ASHRAE BACnet Standards (ANSI/ASHRAE Standard 135-1995) Subclause 12.1.
|
State Text
|
In the State Text field, specify the text that will appear on the Properties page when the device is in each state. The values used to indicate the states for a Multi-State microblock must be greater than 0.
NOTE Up to 10 states can be entered for the BACnet Multi-State Value Status microblock.
|
Editing Privilege
|
Preset, the default Editing Privilege, indicates that each property in a microblock has an appropriate privilege assigned to it. If you change the Editing Privilege, all the properties in that microblock are assigned to that one editing privilege which is not always desirable.
