Defines the amount of time in seconds between the periodic transmissions of the
present value. This property can be used alone or in combination with the Increment
property.
When the period property is used in combination with the increment property, the
present value will always be updated periodically independent on the transmissions
of the present value due to the COV setting.
Example:

The value of the present value is controlled by a command prioritization mechanism
which is based upon a fixed number of priorities that are assigned to command –
issuing entities (BACnet tasks, control strategy, time program, manual operator
inputs). Each of these entities writes to the present value with its assigned priority
level. The number of priorities is arranged in a priority list of descending priority.
