Local Signal Maintenance Tool
1 Local Signal Maintenance Tool
The Local Signal Maintenance Tool enables the user to create, modify and delete local signals. Local
signals can be created singly or can be created as a series. Local sign als are used typically to store
the results of calculations or to trigger alarms.
Local signals are created in the following tables:-
• LocalRealAnalog_Table
• LocalIntegerAnalog_Table
• LocalDigital_Table
• LocalStringSignal_Table
• LocalTimeSignal_Table
• LocalMultiDigital2_Table
• LocalMultiDigital3_Table
• LocalMultiDigital4_Table
Because of the object oriented features of the OpenEnterprise database they will also automatically
become objects in the RealAnalog, IntegerAnalog, Digital, StringSignal, Time and MultiDigital2
tables, from which the Local tables are derived.
1.1 Command Line Arguments
When launched, the following parameters supplied to the 'COMMANDLINE' value on the
'OpenEnterprise\Tasks\OEToolBox\Editors\Local Signals' key in the Settings Editor will be supported.
–s%Database% -u%User% -p%Password% [-x]
Where:
Database is the data service of the database e.g. “rtrdb1”
User and Password are the credentials of the currently logged-on user.
x is a request to perform an export (all) and close.
1.2 Main Interface
The main interface of the 'Local Signal Maintenance Tool' enables the user to view, create, modify,
copy and delete local signals.
