Actions

The detailed actions for each transition in each crate need to be defined. A first draft of these, for normal runs, are given in the appendix in tables 1, 2, 3, 4, 5, 6, 7, 8.


Further work is required to list the additional actions required for the various types of calibration and test run.


In general, each crate will read all necessary information from the database at the Load step. Some run type independent settings and checks can be made at the Configure step. Final downloading of run type dependent information to the modules can be done at the Start step. It may be wise to use the Resource Manager (RM) package to lock crates (or possibly individual modules in some cases?) against simultaneous use by another partition.


Some actions on the whole system require the use of the TTC system. They are the kind of actions which might naturally be allotted to an overall system controller, but as they require access to the TTCvi are naturally implemented in the TTC crate.


Note that the DSS crate (or modules) are only required in some test setups.
