another BACnet device, or generated by the internal PL/i program. You would not want
this object mapped to physical I/O or to some property in another BACnet device. The
means of setting aside or 'reserving' an object is to simply check 'Global Object'
instead of either of the Map options. If none of the Map or Global check boxes are
selected, the object will not be included in the View Data list or in the XML file defining
the objects.
8.5 Insert, Add, Delete
Clicking ‘Insert’ will insert a blank map before the currently displayed object map.
Clicking ‘Add’ will insert a blank map after the currently displayed object map. Clicking
‘Delete’ will remove the currently displayed map and slide the remainder of the list up
by one slot on the list.
The only time position matters much in the list is when configuring a packed register
that maps a single Modbus register to multiple BACnet objects. The members of the
packed register must appear in consecutive maps unless the ‘Pack Mixed Object Types’
is checked. Do not check ‘mixed object types’ unless you really need to mix analog
and binary objects (for example) in the same packed Modbus register. Packing mixed
object types is very inefficient since the gateway must scan the entire list of object
maps for every instance of packed register. When packing the same object types,
placing them in consecutive maps results in very efficient execution.
8.6 Read/Write Device
When changes are made, the in-sync icon changes to a red X on the right hand side of
this page. When properties are either read or written, the device is now in sync, and
the red X changes to a green check mark. This icon will change on an object by object
basis indicating those objects that are in sync.
When all aspects of device configuration are in sync, between device and tool, the ‘In
Sync’ icon in the top right corner of the screen will change to a green check box. This
is the master In-Sync icon, and will be green only when all other in-sync icons are also
green. This icon is effectively a summary icon.
IMPORTANT: Configuration changes have only made it as far as your PC if you see the
red X on this page. If your hardware is not behaving as expected and you see a red
X on this page, the hardware is probably not configured.
8.7 File Read/Write (XML)
Click the ‘new’ icon to erase all object maps.
Click the ‘open file’ icon to read a set of object maps from an XML file. If you will be
replicating the same configuration multiple times, you will save time by creating a file
that can be reloaded. The currently open file will be indicated in the title bar of the
program.
