ELMB Documentation and Framework Component

Introduction

The Embedded Local Monitor Board ( ELMB) is a general purpose plug-on I/O module for the monitoring and control of subdetector front-end equipment. The ELMB is based on the industry standard CANbus and CANopen has been implemented as high-level communication protocol. It may be used to read analog inputs (such as temperature sensors, voltages, etc.) and for digital input and output. This page contains all documentation and components to set up the ELMB hardware to work with PVSS. The standard way to use the ELMB in ATLAS is to read the data via the CANopen OPC Server, which is also available from this page.

The ELMB project is a collaboration between CERN, NIKHEF, and the Petersburg Nuclear Physics Institute PNPI.
