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 data manager */ tokenInterval_->enableWrite (); /* enable writing to database */ tokenIWriter_ = new rcsTokenIntervalWriter (this); /* create database writer */ tokenInterval_->writer (tokenIWriter_); /* register database writer */
