George’s CBAS Tips, May 2019

Did you know that you can set up groups of users in CBAS that have the same rights as individual users?

To add users and groups in CBAS, go to System, then Program Passwords and you will see the user list:

It’s good practice to create a user and password for everyone who will be using CBAS. Typically, your most experienced users will have rights to view, command, and program nearly everything in the system. Meanwhile, security users might only have rights to see Activity View and acknowledge alarms, but must log in to do so. You might also have less experienced engineers who are only allowed to view data in the system without the ability to command points or make changes to programming.

A New Software Feature in Less than 24 hours

I recently visited one of our customers who expressed to me the fact that he really likes the header points feature in CBAS but wished that he could have more than two points. For those of you not familiar, this software feature allows for you to display any two database points just under the menu bar. These points and their values are displayed consistently regardless of what user is logged in. Furthermore, as with all CBAS point values, the values are updated in real time.

History Save Settings

I think everyone who is familiar with Computrols Building Automation Software (CBAS) is aware that CBAS automatically saves History data, also known as “Trend” data, on all points in the database.  When dealing with Analog points, the frequency and resolution of these graphs is automatically set for you by CBAS. Did you know it is possible to see more detail on a graph?

Schedules in CBAS: Cycles, Logic, and Priority Summary

Did you know that Schedules on both Analog and Binary Output points can have up to 24 “cycles”?

A Cycle is any time that the Schedule commands the point. A Binary point is just 2 possibilities, meaning On\Off, Start\Stop, Normal\Alarm. With 24 cycles, that means you can turn a piece of equipment On 12 times and Off 12 times. Of course, you would have to think of a good reason to do that but you might want to cycle something a few times. To find the Schedule, click any output point then click Program, and you will see the Program Schedule button.

George’s CBAS Tips, December 2018

Are you familiar with the term “hot keys”? The term refers to using combinations of keys on the keyboard as a shortcut to a certain function or action in a program. For instance, let’s say you wanted to copy a file to another folder or attach to an email. First you highlight the file then hold the Ctrl key and press the letter C to Copy. Then you locate the place where you want to copy to, hold down the Ctrl key and press the letter V and the copied file will be pasted. These combinations of Ctrl+C (Copy) and Ctrl+V (Paste) are called hot keys.

Programming Schedules with the Graphical Schedule Editor

There are a few different ways to program a Schedule on a point in CBAS. Go to any output point in CBAS, click the point and go to Program. Then click the Program Schedule button. The most apparent way is to click on a day in the first cycle column and it gives you choices. It’s pretty intuitive because it gives you the appropriate choices and when you make a selection, it goes to the Time column and so forth. Pretty simple.

Tell us a little about yourself…
I’m the youngest of 4 children, born in Walnut Ridge, Arkansas to a farming family. We had 300 acres of rice and soybeans. I took computer science in high school and have been working with computers ever since.

I’ve been at ASU for 17 years where I started in the electrical department and was moved to the controls department when they learned I had a computer background. At the time I started, we had 4 control systems: Trane Tracer, Honeywell, KMC, and Computrols. We have since moved away from the other controls systems and have replaced 90+% of the older controls with Computrols with more being replaced every day. I’ve now been using Computrols Building Automation System for about 15 years. Continue reading CBAS Power User: David Foster

I have been in the HVAC trade for 34 years now, with my past 22 years at Saddleback College. My first introduction to building automation was a Barber-Colman Network 8000 system featuring a server the size of a small desk and 8” floppy disks for backups. It seems DDC technology has improved a little since then. Continue reading CBAS Power User: Alan Cherry

Show Point Relations

Did you know that you can easily discover how points are related to each other through Logic or PID? This can come in handy when you have an Output point that has been commanded but you don’t know exactly where the command is coming from.

Find a point that you are interested in and click it. If it’s an Input point, it will go straight to the Program Screen. If it is an Output, click Program to get to the Program screen. Then click the Show Point Relations button in the top row to the right of the History button. Continue reading George’s CBAS Tips, October 2018
