Current system date or time is sent to the RTU board
periodically with a 10-second interval.
7.2.3.8 Hand-Held Terminal Support
1. You can connect to the RTU board with a hand-held
terminal (HHT) to read or write the configuration of this
RTU board.
2. When a HHT is connected to a RTU board, any setpoint
change made from UI will not be sent to the RTU board.
Some controllers will accept the changes but some will
not.
3. The Supervisory Controller downloads all setpoints and
configuration parameters you changed from UI upon
receipt of a message from the RTU that the hand-held
terminal is disconnected. This will overwrite any changes
made using the HHT.
4. The Supervisory Controller does not accept permanent
changes made via the hand-held terminal to the
Supervisory Controller.
