Configuration file

The deltat.set configuration file is located in the back-end computer in the directory /userdisk0/musr/exp/td_musr/deltat. It contains information on the devices which are accessible with the GUI. A typical structure is shown below:

A "#" at the beginning of a line means a comment.
For the equipment list, the type, name, path and flag need to be defined.
The name can be altered on the GUI using the alias command (where the 1st argument represents the name shown on the GUI and the 2nd represents the name of the equipment. The flag for the equipment can have the values: "S"=possibility to start and stop the front-end, "A"=possibility to start and stop the analyzer, "R"=readonly, "M"=measured, "D"=demand, "U"=update title and "O"=omit. The flag "X" puts the equipment in readonly mode when deltat is invoked without special flag or the id of the user is neither "root" nor "l_musr_mgr". The flag default value is "DM".
