is non-zero. Setting the count to zero will disable the default, and the object will retain the most recent
value obtained.
Delete will remove the rule number shown in the "Map #" box. Insert will insert a new rule before the rule
number shown, and is used for placing rules between existing rules. It is not necessary to use Insert to
add rules to the bottom of the list or to define any rule presently having zero for a source object or
"none" for remote type.
Entering zero (for none) for local object effectively deletes the rule even though it will still appear in the
list until deleted. Unused rules at the end of the list will always show none as the type. If you wish to
prevent these from being displayed, reduce the number of rules enabled.
Initial COV increment and period will only apply if a BACnet client subscribes to COV notification from the
BACnet object assigned to this SNMP client map. These properties may be overwritten by the BACnet
client(s) at any time. The values shown here are initial values, not necessarily the current values.
(Note: COV increment only applies to Analog objects, all changes are reported for Binary or Multistate
objects.)
Units default to no_units, but you may select any of the available BACnetEngineeringUnits values. This
value will simply be read by the BACnet client when the units property is requested from the object this
OID maps to. The units have no bearing on calculations performed. You must select appropriate scale and
offset values to make any required translation between SNMP units and BACnet units. Units are only valid
for Analog objects.
The number of rules enabled simply limits the scope of rule review so that you do not have to review a lot
of unused rules. If the displayed rules are used up and you need more, increase the enabled number.
Rule number simply tells you where you're at on the list of OID maps. Click "next" and "prev" to scroll
through the list. To advance directly to a specific map, enter the desired number in the "Showing" box,
then click Update.
Rules entered on this page only write data to remote devices. Go to the Client Read Map to read data from
those devices. The full parameter set is different for read versus write.
An abbreviated version of a list of rules is shown on this page. Any of the parameters shown may be
