## 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

## P5 System

## 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

## DCS Rack Layout

- Siemens Rail 1

- Siemens Rail 2

- Siemens Rail 3

- Siemens Rail 4

- Siemens Rail 5

## Rail 1
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

- same Design as for FPix
- (only Difference is different labels for Sensors)

- These Connections between TB
- “Solder Pins” distribute the Signals
- of Siemens Relay Module Contacts
- 	4, 8, 13, 17
- to 2 TBs, to avoid having to fit
- 2 wires into the same TB

## Terminal Block

- Phoenix Contact
- Model DFK-2,8
- Part Number 0706016

- Width = 6.1mm

**Note: **this TB requires
- the Metal Plate in which
- it is mounted to have a
- Thickness of **exactly**
- 1.5 mm !

## TIF and SiDet Systems

## 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
