Maximum send time.. The maximum period of time between consecutive transmissions of the current value.
This configuration property sets the maximum period of time that expires before the functional block automatically transmits the current value of the associated output network variable. This provides a heartbeat output that can be used by destination objects to ensure that the device is still healthy.
When used with the node object, the maximum send time is used for the nvoStatus output network variable, and the status of each object on the device (including the node object) is returned sequentially in round-robin fashion, one object status per expiration of the timer.
