Issue
Why does not my Host bindings show up in TAC Vista?
Environment
TAC Vista
Echelon LonMaker
Cause
Host Bindings in TAC Vista could only be from other devices in to TAC Vista, to be able to show values in TAC Vista.
It is not possible to have Host Bindings from TAC Vista to other devices, because these points do not have any information holder in TAC Vista, it is only virtual points.
Resolution
Host Bindings in TAC Vista could only be from other devices in to TAC Vista, to be able to show values in TAC Vista.
It is not possible to have Host Bindings from TAC Vista to other devices, because these points do not have any information holder in TAC Vista, it is only virtual points.
From the manual:
You should not use group bindings when binding to the host.
Important
To make the host SNVTs available in the Vista database, the check box Export Host Bindings to TAC Vista Database must be selected. The check box is found in Vista System Plug-In in the Settings dialog on the TAC Network menu.
Note
Digital and multistate SNVTs should be sent as soon as a change of state occurs and analog SNVTs should be sent as soon as they reach a defined limit. All SNVTs should be sent with a heartbeat determined by the priority of the information. For more information about how to set these parameters, see the LonWorks device documentation.
