Pixel Clean room DCS

* Set ALLOWTOPICVIEW = cern-users

The goal of the twiki is to document information about DCS project for pixel clean rooms.

Current projects

As of 25.01.2019 we have move both projects servers.



backups are located:

\\cern.ch\dfs\Projects\CMSTRKDCS\Fpix Backup 28_01_2019
\\cern.ch\dfs\Projects\CMSTRKDCS\Bpix Backup 28_01_2019


At the moment CMS_TRKCR_PVSS_COND from CMS_OMDS_LB is used for FPix project. The new database in int2r has been requested.

Username Password Database Project
CMS_TRKCR_PVSS_COND * int2r BPix clean room Archive DB

The table contains data point elements archived in the BPix project.

Data point type Archived elements

actual.iMon,actual.status, actual.temp, actual.vCon, actual.vMon


TkPlcReadSensor .dcs.comment, .dcs.master, .dcs.name, dcs.outOfLimit, piw.readBack, qualityFlags.enableMonitoring, qualityFlags.goodness, value.converted

.Actual: .12VPwS, .17VPws, .48VPwS, .HVSync, .MainPwS, .Sync



TkPlcDewPoint .dcs.outOfLimit, .coldestValue, .humidity, .temperature, .value
TkPlcDigitalInput .value
TkPlcReadRelay .value
_OPCServer .LastUpdateTime
A trigger is acting on FWCaenChannel and TkPlcReadSensor tables to add current cabling Ids into each new record of the 2 tables.

List of alarms


description of alarm datapoint

vaisala hight dew point

alarm dew point > -30

warning dew point > -40


Current issues and status

add dew point to PLC for both projects

reinstallation of framework components with the new version (we still have components from 3.11 installation)

insert new aliases to the database

fix CAEN heartbeat (Anna)

archive PLC read relays

check panic in the PLC

OPC servers still not working

set up lunch SMS on both projects

Logo notification (from Piero)

Dry gas panel

review log collector

Identification of CAEN channels and PLC sensors

PLC sensors are identified per half cylinder, with the following agreement:

Half Cylinder ID
BmI 1
BmO 2
BpI 3
BpO 4
IDs are stored .currentCoordinate data point elements.

Coordinates of CAEN channels are stored in the format XYZ where

X=1,2,3,4 is half cylinder, accordingly BmI,BmO,BpI,BpO.
Y=0,1,3,4,5,6,7,8 is a sector S1,.., S8 accordingly, and 0 indicates that this is CCU.
Z=0,1,2 is a layer, where LAY14 -> 1 ,LAY23 -> 2, 0 indicates it is controlled power.
