Num in parts max betwen 2 buffers
Nicolas
I would have 10 parts maximum between 2 buffers only, (Between there is 3 machines).
In Scl first buffer, I've write:
USER_ATTRIB
count : real
procedure myproc()
VAR
proc_id : Process
begin
require part ANY
celem->count = celem->count + 1
if (celem->count > 10) then
return
endif
pass()
end
For the second buffer after the machines
procedure myproc2()
VAR
proc_id : Process
begin
require part ANY
celem->count = celem->count - 1
pass()
end
Do you have a solution?
Thank for your help
Have a good day

Hi Nicolas:
Try this:
1. Create a User Group
Advanced->Grp->Group Type->Cre
Any name would be OK
Entity Type Element
Association Multiple
2. Modify the Group
Assign Group Capacity 10
3. Add the Machines to the Group
This sets a maximum total number of parts (10) for the sum of parts in the machines.

Hi Nicolas:
As you mention that you are new to this, I thought I’d add some extra information.
The Group approach works fine as described in my previous email.
However getting ramped up with SCL will be a big advantage – and you have made some good steps.
So I am providing an SCL approach.
There are usually multiple ways of doing things in QUEST. My preference is – use the GUI first and SCL only when you need to. However some people draw the line in a different place and use SCL more that I would. They are not wrong, it is a personal style/preference. In any case at some point you will need SCL.
Your approach – modifying the Process Logic of the Buffer is a good start.
However a User Attribute has a value for each element that it is used on, it does not have a single value across all elements on which it is used. For this you need a Global Variable.
VAR
count : real
--For the first buffer before the machines
procedure myproc()
begin
-- Don't accept a part until it can be passed downstream
Wait Until count < 10
require part ANY
count = count + 1
pass()
end
--For the second buffer after the machines
procedure myproc2()
begin
require part ANY
count = count - 1
pass()
end
If you want the parts to queue up in the first buffer, you could return the Process Logic to its default and modify the Route Logic instead.
