GCL+ I little help wrapping my head around program arrays.

[jmelvin]

For the life of me I can not grasp this. Anybody good at breaking it down in the simplest terms?
I'm writing a program and have hit a road block!

A little background on me.
Only got into controls a year ago. Most of my background in Web design.
I work with Delta exclusively at my work. From planning, installation and programming and commissioning. I have been through GeorgeU all as a Master.(As if that really means anything...lol)

Thanks in advance.

I think you are gonna need to get a bit more specific. Are you asking how the coding works? It uses if then, Boolean, and logic statements.

IF 'AHU Occupancy' THEN
START 'AHU #1',
ELSE
STOP 'AHU #1'
END IF

You could write the sentence as,

If AHU Occupancy is on then start AHU #1 else(if not) stop AHU #1.

This code would start and stop the ahu based on the occupancy timer.

you could code it tons of different ways.

ie:

Variable a
If AHU1 Occ Sched Then Start a
Else stop a
End If

AHU1 = a

There is no right and wrong way, just use what is easiest for you .... as time goes you will probably adopt new ways to write code.
also don't be afraid to use the help file as it is very useful when starting out...

enjoy !

I am writing a Que backwash program for four filters. I write hvac and lighting programs all day long to the point they bore me. We are now automating some of our large filtration systems and they require some very different scenarios.

I have four tanks. They go into backwash based on effluent. If it drops below 700 gpm it triggers that filter for backwash.

Hi jmelvin,

I am confused as to what you are asking... If you are writing programs all day to the point where they bore you then why are you asking to get your head around GCL+.

just follow the sequence that was in the spec.

[jmelvin]

I guess I wasn't detailed enough..lol. I don't need help in understanding GCL+ as a whole just arrays.
I think I have figured it out some.

Example:
Constant Coder (1,2,3,4) (1,2,3,4)

Sometimes working it out on paper gives me that A-ha moment and the light turns on!
Anybody thought of creating a place to share programs?

[CE-TECH]

Di you get this figured out?

[jmelvin]

I believe I understand it better now. It doesn't fit into my current project, but I am sure I will find a use for it.
