Motor Configuration Files

The configuration files consist of the motors' and mechanisms' keywords, the mechanisms' configurations, the motors' configurations, as well as, the I/O modules' configurations.

The mechanisms' configurations essentially correlate motor positions with names and ordinal positions. The relevant configuration files are used by the keyword library each time 'show' or 'modify' is applied to a keyword.

The motors' configurations consist of the specifics for the motors associated with the mechanisms. The information is used by the motor daemon when it initializes.

The default/operational configuration files exist in /kroot/kss/nirc2/mech/keyword/config/.

A set of configuration files also exists in ~nirc2eng/motor_config. This set of configuration files is intended for use by the PI during integration with the dewar (ie. it is a work-in-progress directory). Note that this directory has the same CVS repository as the operational directory mentioned above.

There is a unix environment variable associated with each of the configuration files. This allows changing the configuration (on the fly for those used by the keyword library) when testing, trouble-shooting, or implementing work arounds, as well as, restricting control on a user-by-user basis.

The environment variables are setup via a unix script file which would typically be 'sourced' from within a user's .cshrc file.

If nirc2_motor.config is modified then the motor daemon must be restarted before the changes take effect.

If nirc2_io.config is modifed the the io daemon must be restarted before the changes take effect.

Changes to any other config files will immediately affect the keyword library and, hence, any show and modify calls.

The following table equates the environment variables with the configuration files.
