Using parameters on a network

If using CitectSCADA on a network, you can use parameters globally, locally (local to each server and client), or both globally and locally. Any parameter set in the project database applies to every client unless the parameter is also set in the citect.ini of a Control Client. The value set in the local citect.ini file takes precedence over the project database for that client only. For example:

Here, a parameter (Parameter x) is set to a value n in the project database (on the file server). When the system is running, this value (n) applies to the alarms server and both clients. The same parameter is set to different values for both the I/O Server and the trends server (set locally in the respective citect.ini files). When the system is running, the I/O Server uses the value p for the parameter, and the trends server uses the value m.
