Communications
Driver
The relevant communications management system for
OMRON PLCs in conjunction with Microsoft Windows,
providing facilities for other SYSMAC software to
maintain PLC device and address information and to
communicate with OMRON PLCs and their supported
network types.
Constant Within CX-Supervisor, a constant is a point within the
script language that takes only one specific value.
Control Object In CX-Supervisor, a control object is applied in the
development environment and can be a pushbutton, a
toggle button, a slider, a trend graph, a rotational gauge
or a linear gauge. Essentially a control object can be a
complex graphic object consisting of a number of
primitive graphic objects, which provides user interaction.
CX-Server An advanced communications management system for
OMRON PLCs providing facilities for software to
maintain PLC device and address information and to
communicate with OMRON PLCs and their supported
network types. CX-Server supports CS-Series PLCs.
Database
connection
A Database connection (or Connection for short)
contains the details used to access a data source. This
can either be via Data Source Name (DSN), filename or
directory.
Database
Connection Level
A Database Connection Level is a string which
determines what level in the database tree hierarchy is to
be operated on. Some examples are listed below:
Database
Recordset
A Database recordset (or Recordset for short) is a set of
records. This could either be an actual Table in the
database, or a table that has been generated as a
consequence of running a Query.
Database Schema A Database Schema (or Schema for short) obtains
database schema information from a Provider.
Database Server
Query
A Database Server Query (or Server Query for short) is a
query that is stored in the actual Database. They are
pre-defined and added by the database designer which
means they are 'fixed' for the duration of a project.
Server Queries may have pre-defined 'Parameters',
which allow criteria to be passed to the query at runtime
e.g. values to filter, allowing one query to be used to
produce different results. Each pre-defined parameter
must have a Parameter Association defined. Because
these queries are stored in a compiled and tested form
they are more efficient and therefore preferential to
running a SQL Query.
