Communications

Communications Enabled allows you to enable network communications on this point. Select False when troubleshooting.
|
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.
|
(Display) Name
|
The microblock label used in the interface. You can use any characters (including spaces) in this field, except for the " character.
|
Address
|
The Address field can contain a BACnet object property reference. If this microblock is used in a Portal module, the Address field can contain a reference to a third-party point that utilizes a protocol other than BACnet. See the Portal documentation for more information. You can also enter the Address using a tree control on the Properties page in WebCTRL.
When the Address field contains a BACnet object property reference, the Analog Network Input microblock will attempt to subscribe to the COV Service of the referenced microblock property. If COV Subscription succeeds, the Refresh Time is ignored and the microblock will receive data whenever the referenced property value changes by at least the COV Increment set on the point it is subscribing to. If COV Subscription is not successful, the Refresh Time allows you to set a time interval in minutes and seconds between reads of the referenced property. If COV Subscription has failed and the Refresh Time is zero, the property will be read once per second.
|
Refresh Time
|
The Refresh Time allows you to set a time interval in minutes and seconds between writes to the property referenced by the Address field. If you set the interval to zero, the point will only write when the value differs from the last written value by at least the amount specified by the COV Threshold. If the Refresh Time is anything other than zero, the COV Threshold is ignored and the property is written at the specified interval.
|
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.

NOTE Alt+click any value in WebCTRL to view property details, including its expression and editing privilege.
