Cyclic Actions Overview

A cyclic action repeatedly runs a SCADA Basic program at a configurable period. Up to 512 Cyclic actions may be configured. The minimum period is 1 second.

Cyclic actions are different to Scheduler actions where an action is triggered at a specific time.

Using a cyclic action to run a program you can:

  • Run an entire program or an individual function from a program.
  • Pass a database branch to the program or function.
  • Pass up to 10 arguments to the function.

Generating cyclic actions by program

Cyclic actions may also be configured using the CYCLIC instructions from a SCADA Basic program. These are known as temporary actions as they can be created and deleted under program control.
