2. Overview In total, the CMS Pixels would like to have
3 Siemens S7-300 Systems:
1 installed at P5
to be used by BPix + FPix for the Engineering Run
and final Detectors
1 installed at TIF
to be used by FPix for Commissioning at CERN
1 installed at SiDet
to be used by FPix for Commissioning at Fermilab

3. P5 System

4. Remarks on P5 System The P5 System consists of: 2 Relay
1 Digital Input
1 Analog Input
32 RTD
Modules
The Modules are mounted on 5 Rails,
hosted in a CERN 19” Rack

8. Remarks on Cabling Rail 1 Rails 2 – 5 Relay Digital Input
Modules connected via Terminal Blocks
Analog Input
Module can be connected as for SiTracker
Rails 2 – 5
RTD
Modules can be connected in a modular way:
A Pair of 2 RTD Modules gets Input from 1 (72-wire) Field Cable,
Connected via a 78-pin SubD Connector
From the 72 wires, 4 wires need to be feed
into the HMX Conditioning Board.
We propose 4-pin “Burndy” connectors for this purpose.
The other 64 wires are split into two groups of 32 wires each,
That are connected to 40-pin Hirose connectors

18. TIF and SiDet Systems

19. Remarks on TIF/SiDet System
The TIF/SiDet systems are foreseen for Commissioning
of individual FPix Half-Cylinders
(one Quarter of the whole FPix Detector)
Because only a Quarter of the FPix Detector (and no BPix) needs to be
controlled at a time, less RTD modules are needed for Detector Control
than in the P5 system.
On the other hand, 2 additional RTD modules plus 2 Analog Input modules
are needed to control the Cooling-Box that keeps the Half-Cylinders at -10oC
during Commissioning.
So, the TiF/SiDet Systems consist of:
1 Relay
3 Analog Input
6 RTD
Modules
The Modules are mounted on 2 Rails
