The Tasks
tab of the Project Explorer organizes the worksheets that are
processed as background tasks during project runtime.
Figure 1. Tasks tab
of the Project Explorer
The folders on the Tasks tab are described on the
following pages:
- Alarms contains
the
Alarm worksheets used to
configure alarm groups and the tags related to each alarm group in
the project. You also use the Alarm task to define the alarm
messages generated during project runtime.
- Trend contains the
Trend worksheets used to
configure history groups that store trend curves for the project.
You can use the Trend task to declare which tags must have their
values stored on disk, and to create history files for trend
graphs. Your project stores the samples in a binary history file
(*.hst), and displays both history
and on-line samples in a trend graph screen.
- Recipes contains
the
Recipe worksheets used to
configure how data is exchanged between the project database and
disk files in ASCII or DBF format, and how values are transferred
between files and real-time memory.
- Reports contains
the
Report worksheets used to
configure reports (text type) that are sent to a printer or a disk.
Reports tasks allow you to configure text reports with system data,
which makes report creation easier and more efficient.
- ODBC contains the
ODBC worksheets used to
configure how the ODBC interface runs in a network environment and
uses standard Windows ODBC configuration. You configure ODBC tasks
to exchange data between your project and any database supporting
the ODBC interface.
- Math contains the
Math worksheets used to
configure and implement additional routines to work with different
tasks. Your project executes Math worksheets as Background Tasks
during runtime. You can configure Math worksheets to provide free
environments for logical routines and mathematical calculations
required by the project.
- Script contains
the
Startup Script and other
Script Groups.
- Scheduler contains
the
Scheduler worksheets used
to configure events using defined mathematical expressions, which
are executed according to time, date, or other monitored
event.
- Database/ERP
contains the
Database worksheets that
communicate with external databases using the standard ADO.NET
interface (as an alternative to ODBC).
