1. André Augustinus 10 March 2003 DCS Workshop Detector Controls Layout Introduction

2. André Augustinus 10 March 2003DCS Workshop 2 Motivation  Capture the current state of knowledge on your controls layout Also triggered by “installation review”  Concentrate on the hardware layout of your control system  Get an idea on what, where, how many Radiation and accessibility for equipment in the cavern  See Robert’s talk this afternoon

3. André Augustinus 10 March 2003DCS Workshop 3 Method  Provided you with a drawing showing our knowledge (TDR, URD, presentations, discussions)  Appended a list of questions  Requested you to show today an update of the drawing and answers to the questions  Example for muon tracker

Field and process layer, with their processes “Generic” architecture for the DCS “back end”

[ethernet interfaces are not indicated] The software interface to the equipment (e.g. commercial OPC server) The software interface at the client side (e.g. OPC client in PVSSII) This depicts a task on a PC, each box does not necessarily correspond to a single PC ISEG 1 This depicts equipment to be controlled. This indicates the number of units (usually crates) This depicts the communication media or type of cable (see table) C 3 This indicates the number of busses or cables Alice Control Room (ACR) Counting Rooms in PX25 (CR1 – CR4) and Plug Cavern, outside L3 magnet Cavern, inside L3 magnet Areas at ALICE Detector HV This depicts the cable from the equipment to the hardware (see table) 3 This indicates the number of cables or channels This depicts the hardware connected Explanation of the detector drawings, field and process layer
