5.6.10 TIME

The TIME producer broadcasts the time stamp object. This TIME provides the simple network clock. The time
stamp contains the Time of day, which is represented by a 48 bit sequence. These sequences represent the
time in milliseconds after midnight (28 bits) and the number of days since 1984-01-01 (16 bits). Only one
Timestamp producer is allowed in the Network.
The time and the date have to be configured by setting BFM #51 to #57 (clock data).
In order to guarantee timely access to the network, the TIME is given a very high priority CAN-ID. CANopen
devices that operate a local clock may use the TIME object to adjust their own time base to that of the time
stamp object producer.
The consuming and producing setting can be directly changed by BFM #50.
In case of time overflow (time later than 31st December 2099 23:59.59), the time returns to 1st January 2000
00:00:00. Buffer memory display for year will be 00 to 99 in all cases.
Note for TIME consuming: A received Time stamp before 1st January 2000 00:00.00 is set to 1st January
2000 00:00:00.

5.6.11 Store parameters

To store all parameters to non-volatile memory, write SDO H65766173 (ISO8859 String code: "save") to
Object Index H1010, Sub-Index H01 or use the store command in the CIF. After each power-up or reset, the
saved parameters will be valid.
Note
For CDCF files stored on Object H1F22, the store parameter command is not necessary.
