REMARKS
The send time interval of one network variable is time set in Pr. 388 (Pr. 389) independently of the number of
monitors bound by network management packages such as LonMaker.
For example, when the speed monitor and output current monitor are bound, the send time interval of the speed
monitor is Pr. 388 (Pr. 389)s and the send time interval of the output current monitor is also Pr. 388 (Pr. 389)s.
In addition, the actual send time interval is 1.1s due to constraints of each data send time even when Pr. 388 Send
time interval at heart beat is set to 1.0s or less. (It takes 1.2s when monitor data is set.)
