On a machine where a parameter is set in both the project database and the citect.ini file the value contained in the
citect.ini will be used by that
machine.
For example, in the diagram below the project
value for parameterX (which is stored in the project database) is
n. This is the value used for
parameterX on every server and client EXCEPT the I/O Server and
Trends Server, both of which use the values set in their local
citect.ini files (p and m
respectively).
A parameter which is global to a project and
applies to the majority of servers running a project is recommended
therefore to be defined in the project database where it can be
centrally managed and controlled. Any exceptions to this global
value can then be managed by modifying the citect.ini file on the machine to which the
exception applies.
Where a parameter is not set in either the project
database or the citect.ini file,
the default value for that parameter will be
used by the system.
