Time stamp setting procedure
To keep the consistency of Time stamp data, clock data should be set by the following procedure.
1) Set Time stamp producer/consumer in BFM #50.
2) Set clock data of Year, Month, Day, Hour and Minute in BFM #51 to #55. (Producer only)
3) Set clock data of Second in BFM #56.
All clock data will be written to the RTC and checked for validity when BFM #56 is written to. If the data is
not valid, the RTC will not be set.
4) Set Time stamp transmission interval in BFM #58.
The first time stamp will be sent after BFM #58 is written to.
Time stamp read procedure
To keep the consistency of Time stamp data, clock data should be read by the following procedure.
1) Read clock data of Year from BFM #51.
All clock data will be read from the RTC and written to BFMs #51 to #57 when BFM #51 is read.
2) Read clock data of Month, Day, Hour, Minute, Second and Day-of-the-week from BFM #52 to #57.
6.20 [BFM #70] NMT Start all Nodes delay
During the NMT master startup, the NMT master sends a NMT Reset communication all Nodes and NMT
Start all Nodes depending on the configuration.
This BFM value sets the minimum time between these two NMT messages, to ensure that a slow NMT Slave
recognizes the NMT Start all Nodes message.
The value can be set in ms (default: 500ms).
The setting range is 0ms to 65535ms.

For NMT Startup process, refer to Subsection 5.8.4
6.21 [BFM #71] SDO Time out
The Time out for SDO communication set with this BFM.
The value can be set in ms (default: 500ms).
The setting range is 50ms to 32767ms.
→ For SDO, refer to Subsection 5.6.4
