New ease-of-use features in the 4.0 flow chart editor include a full grid system, which auto-aligns all flow chart elements.

It also lets the user program an event or exception, which will automatically return the control logic from wait loops or subroutines to a.

It also lets the user program an event or exception, which will automatically return the control logic from wait loops or subroutines to a safe state without additional programming or back-checking.

Online cross-referencing traces a tag into every program, subprogram or special function, and displays a view telling where and how it is used.

The way we (as BAS programmers) achieve this is through a concept known as logic blocks.

Not because I dont know how to program but rather because each company has a different set of programming tools.

So therein lies the rub, how do you teach a topic that is unique to each vendor.

Even if youve been programming controls for several years you will still find some nuggets in this guide.

From there we will look at the most common logic blocks and how they work.

Then we will dive into several of the step-by-step processes that I use when I am programming.

That would be a huge mistake as this guide covers so much valuable information.

What you need is a logical mind and an understanding of all the variables.

If I gave you a 0 to 10 VDC and told you to pull it into your control in order to control a valve could you.

The good news is we arent talking about Ph.D.

But wait, Im assuming you know what a proportional scale is.

In the graph above for each 1 of relative humidity is 0.1 VDC so 10 relative humidity would be 1 VDC.

So for this example, you would set your range of 0 - 10 VDC to equate to 0 - 100.

To do this you need to know the level of granularity you want.

The easiest way to determine the scale is to divide the input range by the output range.

But lets say you dont have the sensor type as an option in your controller.

When you select a specific temperature sensor type you are telling your controller to use a predefined range of input to output relationships (in this case resistance to temperature).

For example, your zone temperature setpoint is a virtual variable.

It does not physically exist as there is no zone temperature setpoint device.

The data from this sensor is then shared globally, meaning to all controllers.

This setpoint could be adjusted by any user who has permission to access the setpoint.

Well in order to make sure this doesnt happen programmers will hard-code minimum run times into their programs.

As you would imagine you dont want folks just randomly changing these variables.
