Quick notes

Periodic checks

Ctrl script n.11 bpim_timed_acquisition performs a periodic check:

• the timed function for the periodic acquisition: duration 60s, repeated every 180s
• the same function is used to check the timestamp of the intensity readings (if the beam is present) and force an IFIFO reset in case the board are not reading since >360s
• a dpConnect to the lhc_monitoring:aliDcsRun_1 (was dcs_ui:DCS_RUN_UNIT) to force the acquisition start whenever an SOR is seen, with a duration of 20s
• a check_if_reading function, comparing the timestamp of the IntensityPerBeam.Beam reading and the actual time: if the beam is present and the delay is >360s an IFIFO reset is automatically performed
• a check_clock function to raise an alarm when the beam is present but the CTP clock is still in LOCAL
• a check_if_TDC_is_configured to automatically reconfigure (with default values) the TDC in case the datapoint BPIM/bpim0x.Parameter.Readings.Phase.TDC_LOAD is found as FALSE

For every alert, an email+sms have been setup, with the configuration stored in lhc_instrumentation:aliBptx_sendAlert

DIP stuff

DIP managers

The project has 2 DIP managers:

Publication

The first manager is DIPCOnfig_1 and is the PUBLISHER All the data are listed below.

Subscription

The manager DIPLHC_BPTX_Config (DIP 2) is a client, and the DIP data are stored in the datapoint type Lhccom_lhc:

 lhc_instrumentation:LHCCOM/LHC.LHC.RunControl.CirculatingBunchConfig.Beam1  (dyn_int 2808)
 lhc_instrumentation:LHCCOM/LHC.LHC.RunControl.CirculatingBunchConfig.Beam2  (dyn_int 2808)
 lhc_instrumentation:LHCCOM/LHC.LHC.RunControl.InjectionBunchConfig.Beam1      (dyn_int 288)
 lhc_instrumentation:LHCCOM/LHC.LHC.RunControl.InjectionBunchConfig.Beam2  (dyn_int 288)
 lhc_instrumentation:LHCCOM/LHC.LHC.RunControl.SafeBeam.Beam1.payload    (int)

Set DIP publication as invalid when BPIM are not reading

The timed script calls a function that calculates the age of the original datapoint. If it's greater than a certain value, the correspondent DIP publication is set as invalid, setting its config :_original.._aut_inv to TRUE.

A warning is sent to the PVSS log and the timestamp of the publishing dp is updated: using the dp_published (above) connected to the original datapoint through a _dp_funct, the original _stime is not changed.

VME registers settings

The VME registers are subscribed in a dynamic way; new registers are added in the lbFwTFC_General.lctl library (TFC_SubscribeAllCounters function), and connected to the corresponding datapoint (BPIM/bpim00.Register.Readings.Q1.Rxxx).

On 2010/09/16 I've added the Alice registers, to avoid a special DIm server providing data in a parallel way:

• BPIM/bpim00.Register.Readings.Q1.R0B0, BPIM/bpim00.Parameter.Readings.Intensity.R_ADC_ALICE
• BPIM/bpim00.Register.Readings.Q1.R074, BPIM/bpim00.Parameter.Readings.Intensity.R_ALICE_TRIGGER_RATE

The following two registers were already connected but not set yet:

• BPIM/bpim00.Register.Readings.Q1.R064, toggle
• BPIM/bpim00.Register.Readings.Q1.R068, regsigne
