Configure controller code

Configure Controller Code

The “Configure Controller Code” dialog has an edit window where you may type in a program. Programs are instructions written as a script and saved by the controller. See the section “Programming” for more information about automated tasks. The section “Script Syntax” is a useful guide in writing the script.

The dialog buttons are organized under three groups.

Program execution

By clicking on the buttons, you may start or stop program execution. The “Peek” button lets you view the current values of the variables and parameters used by the program (see “Peek Dialog”).

Operations

These buttons allow you to load a script file from disk or write the script file in the editor to disk. You may also read the current program on the controller and view it in the edit window, or download the program in the edit window to the controller. The “Code Wizard” is a tool that assists you in composing a new program script.

Controller time

Each controller has an independent battery-backed clock and calendar. The automated tasks use the clock to periodically read the inputs and generate the outputs. Moreover, the current time and date are system variables, which may be used in a program script. Such system variables allow you to implement time-based tasks. For example, if you want to turn a sprinkler on for 10 minutes every hour, the program would read the current minutes and decide if the sprinkler output should be turned on or off. You may synchronize the time of the controller with the PC time by clicking on the button in this group.
