Linac Sequences Definition

Reynald Bourtembourg - 4 August, 2006

This page describes the macros used to change the state of the Linac.
The text written in dark blue is the text displayed during the execution of the sequence in the Attribute SequenceHistory of the sequencer device (elin/master/seq).

Macro Force Save

The Macro FORCE SAVE is almost the same as the macro SAVE SETTING.
The difference is that if the Macro SAVE SETTING doesn't succeed in reading a set point, the macro is stopped, the error is reported to the user and nothing is written to the configuration file.
The Macro Force Save will save all the settings it could retrieve in the configuration file wanted and save a default value for the settings it could not get.
