VISUAL BASIC SCRIPTS TUTORIAL MANUAL

Please refer to the correct users manual for information on a specific module. This guide will cover the elements of BASIC supported on CBW modules with some descriptions, explanations, and examples. If the script is disabled, the ControlByWeb module will not run the script program. The 'Run Script' offers the option to enable or disable the script.All scripts will start when the module boots up and will restart any time settings are submitted.

VISUAL BASIC SCRIPTS TUTORIAL CODE

It is good practice to include comments in your code for explanation. Comments may be inserted into the code by using the ' apostrophe or REM (for remark).An example would be up to five IF statements within each other. You may have up to five nested operations.You must have one space between all operations. Spacing is important: 'a=1' will not work.

To minimize script size, condense logic and delete whitespace.

Please check the the maximum script size allowed for your device by visiting your device's specs page on our website.

The module will not automatically keep running through the script so you must instruct it to do so.

The scripts should be designed to continuously repeat and run within a DO loop.

All scripts must be written and then saved to a text file (*.txt) and then uploaded to the module.

Some basic notes to keep in mind when writing and using a script: A bench test should demonstrate that the script will function exactly as intended. It is highly recommended to explore all options and test all functionality before the module is connected up to live equipment. The module will attempt to identify the error and point out the line in which the error is located.ДЄs you can see in the picture below, the Interpreter Status shows that I misspelled an external variable. Method 2 - Anytime a program is uploaded to a module and the code is run, a message will indicate if the programming is running, finished, or has an issue. This is a command line utility and is available here: BASIC Script Error Check utility

Method 1 - A Windows utility has been developed to assist in finding errors in scripts. All three methods may be used to verify that a script will work correctly. Three methods are given to help find errors. Every program may have typos, mistakes, or logic errors. Even two scripts written for the same purpose may be written differently.Д«efore the programming steps are shown, it is important to show debugging steps. A script written to email every 10 minutes will be very different from a script written to unlock a door during business hours. The script will perform exactly as written.Д®very script is written with a different goal in mind. The point of this simple example is to illustrate that every action and step must be programmed into the script. The computer would continuously repeat the steps of Lather and Rinse. If these instructions are given to a computer, would the computer ever stop washing hair? No, because there is no exit from the cycle 'Lather, Rinse, Repeat'. Think of the standard instructions given on a bottle of shampoo: 'Lather, Rinse, Repeat'. To begin talking about the functionality of a script, it is helpful to share an example given in many introductory programming classes. Please use this guide along with a ControlByWeb product's users manual and examples to create a script. Also included are a few examples and tricks that more advanced users may find useful to modify for particular applications. This tutorial will assist in creating a custom BASIC script to do advanced logic tasks on ControlByWeb modules. It is written to give more explanations to users who do not have programming experience. This tutorial is not designed to be a comprehensive resource on programming. Please see the X-600M's users manual for more information. The X-600M uses a different language for the coding, called LUA. Most of ControlByWeb advanced modules support BASIC scripts. A script program used on ControlByWeb modules allows for custom logic and capacities beyond regular settings found in the product's web setup pages. The individual ControlByWeb product's users manual will have more details and examples for all supported commands. Many ControlByWeb modules have an interpreter that supports many BASIC commands however, not all BASIC commands are supported. BASIC is a computer programming language that has been in use for many years.
