Quick Help
The
object name, units, value, and status are shown for the object number
entered at the top of the page. Click Prev/Next to scroll through the
list. Click Refresh to update the page, or Update to accept changes. The
object name and description may be changed here. BACnet units may be
selected. Initial COV increment may be entered. When any of these are
changed, be sure to save the updated configuration by clicking Save on
the Config File page under System Setup. The
object may be set Out of Service by checking that box and clicking
Update. The present value may be changed by entering a value, checking
Force, and clicking Update. Analog
Value objects may be both a source and destination for some other
BACnet or Modbus device. The source of data for the Value object
will be reading from a remote device when associated with a Read Map.
The destination of data for the Value object will be writing to a remote
device when associated with a Write Map. If a remote device is mapped,
the device links are displayed above. You may click on either link to
view the respective mapping. The
Value object may be simultaneously associated with both Read and Write
maps pointing to the same remote device object. When this Value object
receives new data (from any source), this data will be written to
the mapped remote device before any subsequent read from the same
device. Thus the Value data is not discarded by the read operation
before the new data can be written. Out
of Service means polling of the remote device will stop. While out of
service, the present value may be written by an external BACnet client
but it will not be written to any mapped remote device. Data may be
forced via this web page at any time, but will be overwritten by the
next read from a remote device unless the object is out of service. Reliability codes indicate errors as itemized on the tabular object list.
Status flags A,B,C,D indicate the following, 0 meaning not true, 1 meaning true: A = in alarm B = fault C = overridden D = out of service Device
link will indicate RTU, TCP, or BIP, followed by R for read or W for
write, and a number which is the map number in the table of read or
write maps for mapping to this BACnet object. The designation R means
read from a remote device, and W means write to a remote device. Check 'Deconfigure' and click Update to erase configuration for this object. |
