  4. rtsIoTask flowchart Semaphore from INITIALISATION no Trigger reschedule & report Error rtsStartCheck() =Error? yes rtsDelete=1 return no yes rtsDelete=1 rtsIoInit() =Error? rtsIoreInit() no rtsPreHandShake() =Error? yes yes no Semaphore from SEQUENCE yes yes return Opmode=0(FIXSAMP) or=1 (FIXITG)? rtsStdSequence() =Error? yes no Opmode=2(EXTCLK) ? rtsNonStdSequence() =Error? no no no sprintf (errmess, "At least %s %s . INPORTS[1][0] logic=%04X %04X", sysname, rtsErrStrings[(int)rtsInfoprt->outResult[0]],rtsInfoprt->outResult[2], rtsInfoprt->outResult[1] ); ErsRep ( 0, status, errmess );

  5. rtsStdSequence() flowchart FIX SAMP? Setup time1, enable time1 no putNSCNDV(p) (enable time1) SeqNo=1? FIXSAMP? yes no rtsTimeSC() =Error? timeSC=-1? putNSCNDV(p) (disable time1) putNSCNDV(p) (disable time) yes yes waitNSR(p) =Error? waitSR(p) =Error? yes return waitNSR (p,stTimeout) =Error? FIXSAMP? putSCNDV(p) (enable time1) yes yes putSCDV(p) (enable time1) rtsTimeRead() no semWait4Time1() =Error? return putSCNDV(p) (disable time1) no waitNSR(p) =Error? SeqNo finished? putNSCNDV(p) (disable time1) semGive TimeStamp rtsTimeRead() yes return

  6. rtsNonStdSequence() flowchart rtsTimeSC() =Error? timeSC=-1? yes putSCNDV(p) yes return putMask (SRMask) yes no waitSR&Samp (p,Timeout)=Error? putNSCNDV(p) putMask (SRMask| SampMask) waitNSR (p,stTimeout) =Error? rtsTimeRead() putSCDV(p) yes yes return semWait4ExtClk =Error? enable ErrINT rtsTimeRead() putSCNDV(p) Check if one SR drop? yes putMask (| SampMask) yes no no waitSamp (j+1) (p,sampTimeout)=Error? waitNSR(p) =Error? SeqNo finished? putNSCNDV(p) semGive TimeStamp yes return

  8. Protocol-1 preliminary check First Sequence Start check waitNSR(p) waitNSR waitSR waitNSR(p) waitSR(p) SR timeSC(I) Start time1 FIXSAMP SC Time interrupt Stop time2 FIXITG, continue time1,FIXSAMP putNSC(p), putNDV(p) putSC(p), putNDV(p) putNSC(p), putNDV(p) putNSC,putNDV putSC, putNDV DV Start time2 FIXITG

  9. protocol-2 Middle Sequence waitNSR(p) waitNSR(p) waitSR(p) timeSC(I) SR Time INT Stop time2 FIXITG, continue time1,FIXSAMP SC putSC(p), putDV(p) putNSC(p), putNDV(p) putSC(p), putNDV(p) putNSC(p), putNDV(p) DV Start time2 FIXITG

  10. protocol-3 Last Sequence Finish check waitNSR(p) waitNSR(p) waitSR(p) timeSC(I) SR Time interrupt Stop time2 FIXITG, continue time1,FIXSAMP SC putNSC(p), putNDV(p) putSC(p), putNDV(p) putSC(p), putDV(p) putNSC(p), putNDV(p) DV Start time2 FIXITG

  16. RTS Initialisation File <Connections> <System name=“TCS” socket=“1” /> <System name=“HARPB” socket=“2” /> <System name=“ACSIS” socket=“9” /> <System name=“SCUBA” socket=“3” /> <System name=“TRYSUB” socket=“15” /> </Connections> This provides a list of the physical connections. It doesn’t say whether these are standard or non-standard subsystems, and doesn’t say whether they will actually be used.

  17. RTS Configuration File <Configuration> <TCS SC=“1” SR=“1” DV=“2” /> <HARPB SC=“1” SR=“1” DV=“2” /> <ACSIS SC=“1” SR=“1” DV=“2” /> <SCUBA SC=“1” SR=“1” DV=“2” /> </Configuration> The Configuration lists all the standard subsystems which are going to be involved in the subsequent sequence.

  18. RTS Sequence File The most trivial sequence file is:- <Sequence/> This means that only the standard subsystems as listed in the Configuration file are going to be used.

EXAMPLE (1, initial) RTS - ditscmd "RTS INITIALISE connection.xml 0 ” DITSCMD_1b7f5a8:RTS:rts: got argument = connection.xml iolinks[0].sname=TCS sockNo=1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[1].sname=HARP sockNo=2 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[2].sname=SCUBA sockNo=3 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[3].sname=ACSIS sockNo=9 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[4].sname=TRYSUB sockNo=15 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[5].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[6].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[7].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[8].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[9].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[10].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[11].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[12].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[13].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[14].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 iolinks[15].sname= sockNo=-1 RTS_CONN_SR=-1 DV=-1 SC=-1 DITSCMD_1b7f5a8:RTS:rts: in NON-simulation mode
