Visual
Logic Software (VLS)
What
makes our Visual Logic Software (VLS) so easy to use? The secret is a
specific, yet very simple, method of programming called Function Block.
Function Blocks are small, pre-programmed building blocks of software
that process input data and then turn outputs 'ON' and 'OFF', providing
all the control you need. Pre-constructed icons (Inputs, Outputs, Function
Blocks and Logic Blocks) can be placed on screen and connected with the
click of a mouse button. Thus you have a complete program.
The
Function Block Diagram (FBD) Board contains labelled squares, in which
to place Inputs and Outputs. The Function Blocks can be applied anywhere
on the board. Timer values, 'ON' and 'OFF' patterns, counters, calendar
date and elapsed times can all be optimized for specific applications
by simply double clicking on the Function Block and entering data in the
Option settings.
Every part of your program appears on screen with interconnecting lines. The ability to see relationships between the various parts of your system simplifies both programming and troubleshooting. Since the each of the Function Blocks has a predetermined function, even the most inexperienced user can quickly identify what each segment of the program is doing. For added peace of mind, or personalisation, you can add comments to Function Blocks using the VLS software or by importing text of your own. Once programming is complete, VLS software allows you to simulate the program in Run mode without any hardware. Create your program as outlined above and then turn on the Simulation mode in the 'Controller' pull-down menu. Click on Inputs to turn them on and off. The wires on the FBD Board light when energised, timer values are displayed on screen and Outputs show their 'ON' and 'OFF' status.
