Runcontrol

This page describes run control part of Coda DAQ system. It reside in $CODA/src/rc/ directory.

Communication between rcServer and runcontrol

Lets use 'tokenInterval' as example. It reside in database, and can be changed by runcontrol. Following steps were made to implement 'tokenInterval' functionality:

• rcServer/Components.s/daqRun.h: object must have a type 'daqData' to use reloaded operations etc:

daqData* tokenInterval_; /* variable */
daqDataWriter* tokenIWriter_; /* database writer */

• rcServer/Components.s/daqRun.cc: create object, connect it to manager, and enable writing:

tokenInterval_ = new rcsDaqData (exptname_, "tokenInterval", 0); /* create variable */
tokenInterval_->connect (dataManager_);                          /* register to manager */
tokenInterval_->enableWrite ();                                  /* enable writing to database */
tokenIWriter_ = new rcsTokenIntervalWriter (this);               /* create writer */
tokenInterval_->writer (tokenIWriter_);                          /* register writer */
