1. ITS combined test seen from DAQ and ECS F.Carena, J-C.Marin

2. HW components (seen by DAQ)
3 detectors producing data
3 DDL links (Detector Data Link)
3 RORCs (ReadOut Receiver Card)
(different versions: pRORC, D-RORC)
3 LDCs (Local Data Concentrator)
1 GDC (Global Data Collector)
1 Control Station
Fast Ethernet network
Local disks as storage area

4. DAQ software DATE 5.0 Can be controlled by the ECS
Allows multiple parallel Data Acquisition tasks
The Run Control Human Interface and the Run Control are two interacting processes that may run on different PCs
One single DATE_SITE describing the ITS setup (SDD, SPD, and SSD)

5. DAQ tasks Data Taking for individual detectors (standalone mode)
Without event building
Data recording on LDC local disks
Data Taking for ITS (the 3 detectors or any combination of 2 detectors)
With event building based on Event Identification (orbit counter + bunch crossing) given by the ‘CTP’
Data recording on GDC local disks

6. DAQ implementation
4 DAQ Run Control processes permanently on the Control Machine
1 for each Detector
1 for the global Data Acquisition
With Human Interfaces on any DAQ machine
The 4 processes compete to get resources (LDCs)
The resolution of the access conflicts is left to the Experiment Control System
The synchronization of the DAQ and the Trigger is left to the ECS

8. Simplified block-diagram of the LTU

9. Test-beam system connections

10. An LTU process allows to set
the ‘Mode’ of operation of an LTU (emulator or ‘CTP’)
To enable/disable the BUSY2 connector
A TPA (Trigger Partition Agent) process coordinates the setting (mode and BUSY2 enabling option) of the LTUs involved in a global run to emulate the CTP
one LTU becomes master and plays the role of CTP

12. ITS seen from ECS
From the ECS point of view the ITS is made of 8 objects associated to processes
4 Run Controls
Controlling Data Acquisition for standalone detectors or the global one
3 LTUs
Sending trigger signals to the detectors under the ‘CTP’ control or using the LTU emulator
1 TPA
Synchronizing the LTUs (2 or 3) participating to global runs to simulate the CTP

20. Major results Major step towards the final TRG/DAQ/ECS system
DATE 5.0 successfully used
New Run Control allowing multiple parallel Data Acquisition Tasks
Same version of ‘readout’ for all the detectors
Event building based on information taken from the Common Data Header
Monitoring possible at LDC and GDC level
MOOD has been intensively used by SSD
ECS
The major components ready and used extensively to run…
All the possible combinations of 1/2/3 detectors
Interfaces with DAQ and Trigger worked without problems

21. feedback
The access control mechanism used by DAQ and ECS works and it is necessary, but it is not sufficiently solid to resist to process crashes.
The access control mechanism makes some operation (e.g. redefinition of DAQ run parameters) somewhat difficult and not easy for an operator with limited expertise
The ECS HI can be improved (number of windows, more information,…)
An interactive tool to register operator comments must be provided
