The function of synchronous regime data is identical with effect.
The operating procedure of primary main control unit, standby main control unit and Service Processing Unit is illustrated separately below.
First, primary main control unit operating procedure.
If primary main control unit is in " master state ", for the processing method of following event：
1. the request for data event of Service Processing Unit is received, after carrying out respective handling, data is set to " not synchronous
State ", is saved in locally and is issued to Service Processing Unit.It is issued to the data of Service Processing Unit, the state of carrying
For " non-synchronous regime ".Main control unit be issued to Service Processing Unit data not only can carrier state information, may be used also
To carry other information, such as the unique identification information of data.
2. the online event of standby main control unit is received, is preserved local, and be that the data of " non-synchronous regime " set
" just in synchronous regime " is set to, then the state of this unit is set to " activestandby state ", starts synchrodata to standby
Main control unit.
3. the event of synchronously completing is received, is not processed.
