ODBC
See Open Database Connectivity.
ODBC driver
A driver that processes ODBC (Open Database Connectivity) calls, queries the database,
and returns the results. See also Open Database Connectivity.
OP
PlantScape abbreviation for output.
Open Database Connectivity
A standard set of function calls for accessing data in a database. These calls include the
facility to make SQL (Structured Query Language) queries on the database. To use
ODBC you must have support from the client application (for example, Microsoft
Access) which will generate the ODBC calls and from some database-specific software
called an ODBC driver.
Operating Group
A group of up to eight arbitrarily chosen points that can be viewed by an operator on a
standard Station display. An Operating Group can be defined in Quick Builder or in
Station.
operator ID
A unique identification assigned to each operator. If Operator-Based security is enabled,
the operator must use this ID and a password to sign on to a Station.
operator password
A character string (not echoed on screen) used with the operator ID to sign on to an
operator Station.
operator security level
See security level.
Operator-Based security
Operator-Based security comprises an operator ID and password, which must be
entered at an operator Station in order to access PlantScape functions.
output
A point parameter used to issue control values. The output (OP) is often related to the
mode (MD) parameter and can be changed by an operator only if the mode is manual.
parameter
The different types of values accessed by points are known in PlantScape as “point
parameters.”
