Main Panel

The Main Panel is situated on the left side of the IGUI frame. It allows to steer the data acquisition (DAQ) system and see the status of the Run Control system together with the most important run parameters.

Run Control Commands 

This display shows both the status of the Run Control (that means the status of the Root Controller) and allows to control the Run Control. This panel offers the possibility to send commands to the Run Control system: the commands are sent to the Root Controller, which will then propagate them to all its children. Each command has a correspondence with a run control transitions or a set of transitions and is enabled/disabled according to the run control states. 

The commands are:

Button Action Initial State
Final State
SHUTDOWN Shutdown the DAQ system INITIAL
NONE
INITIALIZE Initialize the DAQ system NONE

CONFIG Configure the DAQ system

UNCONFIG Unconfigure the DAQ system
