I am having difficulty accessing individual BACnet properties in the Ignition Designer.
In the concrete case it is about accessing the property of a binary input. The binary input is found in the OPC Tag Browser, but not all properties are displayed.
I have now tried to access the desired property with a manually created OPC Tag and a customized Tag Path which unfortunately did not work.
My manually created OPC tag with customized path for “Elapsed_Active_Time”.
Many (most? all?) of the optional properties on the Objects supported by the driver are not supported. Support for this property would need to be added to the driver before it would attempt to access it.
Extra properties can be added if there is demand, especially if they’re easier to support types like this one.
Eventually we are going to add some kind of broadcast discovery UI and, unrelated, explore making initialization of a device not require the who-Is / i-Am “handshake” and maybe not require the reading of segmentation / supported services. It’s a little tricky.
