It provides a network transparent inter-process communication layer.” Protocol Distributed Information Management System Originally built for DELPHI http://dim.web.cern.ch/dim/ Some Properties: name based publisher/subscriber mechanism for services and commands Small / Tiny Many platforms No (not yet) inherent access security No logic Dynamic Used as network protocol for LabVIEW based CS Control system (GSI) … another Gateway to LabVIEW Embedded EPICS on ETRAX install embedded Linux on ETRAX chip CPU () based front-end systems 2 step approach: Install DIM on ETRAX and use EPICS-DIM Interface to communicate via network with external EPICS clients or IOCs Suitable for development: DIM protocol also accessible via other controls software, i.e. LabVIEW, or CS, etc. But locally no (EPICS) logic (database, (fast) sequencing, alarming) provided Install EPICS Embedded on ETRAX Provide
