FSM configuration and FSM configuration and functionalityfunctionality

- current status- current status

- plans- plans

FSM creation

• FSM hierarchy is built using SIT-Aliases, „underscore“ as Separator:

– (lowest level-)CU: Layer_PCC_ROgroup• e.g. D1A_B01_S1

or L1_B01_S1_A6

– DU: Layer_PCC_ROgroup_DU• e.g. D1A_B01_S1_M3

or L1_B01_S1_A6_OptoBoard

Units

• ROgroup

• Wiener Channel

• Iseg Channel

• Optoboard

• Module

• Detector

• Layer

• PCC

• ROgroup

FSM states and statiState Iseg WIENER OptoBoard Modules

RUNNING - - ALL channel ON and clock provided by OptoLink

ALL channel ON and Modules configured (FE-by-FE is possible)

READY / ON channel ON

channel ON

ALL channel ON but NO_CLOCK

ALL channel ON

NOT_READY e.g. partly on, Regulator channels inhibited

e.g. NO_CLOCK

OFF channel OFF

channel OFF

ALL channel OFF ALL channel OFF ( no current)

UNKNOWN

DISABLED Module will be kept OFF even if the operator (via the SIT) switch on any channel

Status OK WARNING ALARM FATAL

Module States

• determined by analog and digital current

• (Temperature)• for modularity < 6/7:

HV into Module State?

Software Interlock

• For Module Temperature

• 35°C WARNING, 37°C ALARM– „TEMP_HIGH“

• In Status OFF can at most reach WARNING

• Status ALARM for Module Temperature: Module will be switched OFF tested and working (@17°C)

Commands

• SWITCH_ON

• SWITCH_OFF

• RECOVER

• RESET (OptoBoard)

• (DISABLE/ENABLE)

SWITCH_ONSWITCH_ON @ ROgroups (should reach READY/RUNNING state):

• SWITCH_ON SC-OLink channelSWITCH_ON the WIENER channel for VDD and VVDA– waiting 1 sec.. // WAITING FOR SC-OLINK and WIENER

• UnkillRegulatorBoardSWITCH_ON VVDC Regulator channels for the OptoBoard– waiting 1 sec… // WAITING FOR POWERED OPTO BOARD

• RESET of OptoBoardSWITCH_ON VDD Regulator channels for the modules– waiting 2 sec… // REDUCING CURRENT OVERLOAD DUE TO THERMAL EFFECTS

• SWITCH_ON VDDA Regulator channels for the modules– waiting 1 sec…

• iseg_AcknowledgeInterlockSWITCH_ON HV channels for the modules/ROgroup

Different SWITCH_ON procedure?

Favoured by System test operators:

– Wiener– SC-OLink– HV– PP2 VVDC– PP2 VDD– PP2 VDDA

• HV before LV

Flexible SWITCH_ON procedure?

e.g.

• SWITCH_ON without HV

• Flexible order

→ „Object Parameters“, „Action Parameters“?

→ from DB??

SWITCH_ON (PP2), I

include Initialization of PP2 and check of sense line (Mauro´s procedure)

basically keep normal order, but- to have a well defined startup order (now only partly given for

„RECOVER“), ensure that:• wiener OFF• board killed• set trimmers (Wiener@5V)• inhibit Board (Wiener@2.5V) → new SDO-Item in PP2-ELMB?

SWITCH_ON (PP2), II

- unkill Board before first switch_on of a PP2 Channel- check Vmon reading before wiener at full output voltage

- PDO:- routine should be stopped before long „PVSS-Operations“ (i.e.

startup)- routine always gets items in a certain order- for reduction of load on pc, opc group has refresh rate of only 1

sec

- ramp up wiener to full output voltage

→ Additional time needed for „SWITCH_ON“

Additional Commands?

e.g.

• RECOVER_PP2 – after power cycle of controller reload Inhibits

without clock command for D-flip-flop

• Load_CONFIG– read in xml-File with Configuration (→ SIT)

• default values• from DB
