Next: 4kHz BPM History Buffers Up: Spear Timestamps and Events Previous: Timestamps   Contents


The timestamp hardware is also capable of distributing 7 different, global events to all IOCs equipped with a TSSM. Events can be sent on each 4kHz clock cycle. They can be used to trigger e.g., corrector setpoint tables or BPM history snapshots or for other synchronization purposes.

There are seven binary PVs, Spear:Event1 .. Spear:Event7 which, when set to 1 will result in broadcasting the corresponding event.

I suggest that we reserve Event7 for the orbit interlock, and Event6 for development..

The event PVs are automatically reset to 0 after a period of about 100ms.
