Sending the controller time

Communication

Note!

In controllers with a firmware version lower than 1.05, the master controller receives the Subnet 1 address and node address 1 and is the decisive controller in LON network terms. It is the only controller that can send alarms over a modem.

9.7Sending outdoor temperatures and controller time

Two outdoor temperatures and the controller time can be sent over the LON bus which are taken on by all the other controllers. Any controller in the system can send these data. Either all the data can be sent by one controller or each piece of data can come from a separate controller. The controller time and the outdoor temperature are transmitted every four minutes. The out- door temperature is additionally transmitted if it changes by 0.5 °C. All controllers delete the values received over the bus ten minutes after the last update.

Sending the controller time

The controller time can be made available to all LON participants. They download the transmit- ted time and adopt it. The controller time can be sent with the setting Co7 -> Fb02 = ON. This functions should only be set in one LON participant, otherwise various controller times might be sent. In the case that the controller time of the LON participant fails, the controller time continues to run locally in all other participants.

Function	WE	Configuration
Controller time	OFF	Co7 -> Fb02 = ON

Sending outdoor temperatures

Two outdoor temperatures can be sent. By specifying the terminal number after activating the corresponding function block, the sensor is defined whose measured temperature is passed on. The transmitted temperatures are available to all LON participants.

Functions	WE	Configuration
Outdoor temperature 1	OFF	Co7 -> Fb03 = ON
		Terminal number of outdoor sensor
Outdoor temperature 2	OFF	Co7 -> Fb04 = ON
		Terminal number of outdoor sensor

Note!

The outdoor temperature used by each LON participant is set on selecting the outdoor sensor (select: FUEHL, 0–10, Lon-1, Lon-2).
