  1. EPICS Demo Burkhard Kolb and Peter Zumbruch

  2. Outline • Check connection details • Hardware manual • Test/Debug command • Try simple command/response in text form • Select commands to implement • Hardware manual • Some examples • Set and read voltage/ formatted parsing

  3. Connection details • Check manual for information on: • RS223 parameters (baud, parity…) • TCP/IP name, port number • Command delimiters

  4. Extract from manual • From the Agilent N5700 manual:

  5. Connection setup • In the startup command file “stAg.cmd” epicsEnvSet("STREAM_PROTOCOL_PATH", "/u/cbmdcs/apps/StreamTest/protocols”) ## Register all support components dbLoadDatabase "dbd/hades.dbd" hades_registerRecordDeviceDriver pdbbase drvAsynIPPortConfigure("ps001", ”hadps001.gsi.de:5025") ## Load record instances dbLoadRecords("db/Agilent1.db")

  6. Record and protocol definition • In record database file (Agilent1.db): record(stringout, "HAD:MDC:PS:01:DEBUG") { field(DESC, "Debuging help") field(DTYP, "stream") field(SCAN, "Passive") field(OUT, ”@Agilent.proto debug ps001 ") field(ASG, "mdc") } • In protocol file (Agilent.proto): Terminator = LF; # After processing finishes, the record contains the reply. debug { ExtraInput = Ignore; out "%s"; in "%39c”; }
