Many many decades ago I had a Math teacher in High School who bless his heart left a high six figure job to teach at my inner city High School. Unfortunately he taught our class as if we were all Nuclear Physicist. That year many of us students just stopped going to class because we weren't learning anything. I'm in my 50's now and always think back, what would have happened if I would have had a down to earth Math teacher who was gifted in teaching in a simple to understand common sense way. You sir have that gift. Thank you for your videos, by far this was the easiest to understand. I have been in the control industry for 10 years now ( installing and operating ) and have always wanted to learn the programming side of the business. In those 10 years I have never encountered any simple to understand common sense lessons. You keep things simple and it is much appreciated, keep up the good work.
I really appreciate the way you have built up the learner's attention in all ur videos. This is really encouraging to find a free source to decode the bacnet thing. I'm really thankful for your such videos. I am struggling with few things in my building' BMS system, which are: 1- what is mean by binding of binary points? 2- whether supervisory or the field controller actually giving control command? 3- how to discover a new device, and if I don't have BTL certificate, shall i entertain the supplier? 4- How to prepare graphics and make the parameters settings? Etc. Can u guide me specific videos for these?
1- what is mean by binding of binary points? Binding is the act of connecting points together. 2- whether supervisory or the field controller actually giving control command? It depends on how you view things. The command usually comes from the graphic to the logical setpoint at the controller but then the controller executes code based on this setpoint to drive the physical outputs. That being said you can command outputs directly from the controls logic. 3- how to discover a new device, and if I don't have BTL certificate, shall i entertain the supplier? Device discover is product specific but basically you setup your MS/TP or IP trunk and run a discovery (who-is/I-Am). BTL is hit or miss all BTL means is that you paid a fee and checked some boxes to show you implement BACnet device profiles, services, and BIBBS. 4- How to prepare graphics and make the parameters settings? Man this is a huge question and is very dependent on the control system type.
Hey thank you for the video will go straight to video 2. I'm not a programmer but a project manager for hvac systems but I was more then able to follow you.
DDC has Priorities. Priority One is Safety logic. Priority 10 is regular programming. Priority 8 is variable input (Aka Operator Overide) for changing Setpoints. Priority 16 is usually Scheduling programming, like time to turn on, off, etc.
I like to become a Building Automation Tech. Can you please let me know the fastest way to achieve that? will a certification be the best route? if so how can I get one? Thanks
Good stuff Phil. Question ,when you say safety logic should be modified on top, do you mean that once your finished programming a sequence, you go over your program pattern and then modify them to include alarms?
I'm starting from scratch. Just got an office position in a controls company, no mechanical division. Opportunity to move laterally and vertically. Which of the "Big 3" do you suggest I start with, I want to move within this company/industry.
Hello Mr phill I am very interested your explanation methods actually i have completed BE IN ELECTRONICS AND COMMUNICATION. But I'm working in the Building Management/Automation system as operator and Technician from past 3 years so I want to update and upgrade my career in this field as the programming engineer so can you please help me in this. So how can I quickly learn the programming easily in an advanced level of good manner. Thanks .
I had one that was so bad, I made the original settings permanently notated on the graphics as we went through and changed the parameters back. he could still change them, but the notation remained the same.
It is an input that can be passed from a local controller to other controllers on a BAS system. Example- outside air temperature can be a shared point across the automation system.
