Updated: Jan-14 (Subject to change) Page 6 of 15
5.2.1 Description of objects
Object 0 "Receive time"
Receives the time messages from the bus clock, e.g. TR 648 top2 RC KNX
(order no. 6489212) to set the clock.
Object 1 "Receive date"
Receives the date messages from the bus clock, e.g. TR 648 top2 RC KNX
(order no. 6489212).
Object 2 "Automatic synchronisation"
A 1 on this object starts the following process:
The clock stops (second hand stops)
The hands are reset to zero after approx. 5 seconds rest:
First, the second hand is moved to the 12 o'clock position and then the minute hand.
The OSIRIA clock sets itself to the internal time after the hands are set to zero.
This mechanism allows the whole clock system to be easily synchronised again mechanically.
Object 3 "Send time query"
Sends time query to bus timer, e.g. TR 648 top2 RC KNX
(order no. 6489212) to receive the current time.
Object 4 "Alarm message"
An alarm message is sent if no time is received after a set number of time queries.
The number of queries is set using the Report alarm after parameter on the Safety parameter page.
0 = no alarm
1 = Alarm
