Tasks tab

The Tasks tab of the Project Explorer organizes the worksheets that are processed as background tasks (for example, server-based maintenance tasks that are not directly related to screen operations or device I/O) during project runtime.

The folders on the Tasks tab are described in the following sections:

Alarm worksheet

You can use Alarms worksheets to define when alarms are trigged, how they are handled, and what messages they generate.

(You can then use the Alarm/Event Control screen object to display your alarms on screen, but that is a separate procedure.)

Trend Logger

You can use Trend worksheets to select project tags to display as data trends and/or save as historical data.

(You can then use the Trend Control screen object to actually display your trends on screen, but that is a separate procedure.)

Recipes

You can use Recipe worksheets to select project tags that will load values from and/or save values to an external file. These worksheets are typically used to execute process recipes, but you can store any type of information such as passwords, operation logs, and so on.

(You can then call the Recipe function to actually run a configured Recipe worksheet, but that is a separate procedure.)

Reports

You can use Report worksheets to design runtime reports that are either sent to a printer or saved to disk.

(You can then call the Report function to actually run a configured Report worksheet, but that is a separate procedure.)

Math

You can use Math worksheets to develop complex runtime logic using the built-in scripting language.

Script

You can use script worksheets to develop complex runtime logic using:

VBScript

Python

Scheduler

You can use Scheduler worksheets to run commands at specified times, dates, or trigger events.

Database/ERP

You can use Database worksheets to set up connections and exchange data with external databases using the standard ADO.NET interface.

Internet of Things

You can use Internet of Things worksheets to set up connections and exchange information with external databases that send and receive data over the internet. Currently, you can connect to and interact with Azure IoT message queues.
