### FGI Calculation/Sample Time Question

Nick Pridham 7 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 7 years ago

If an FGI transitions through 3 layers of function groups then does it take 3 cycles for a root value to reach its final destination ?

In other words does the IQAN OS pass on all root values regardless of the calculation layers in one sample time?

### Looking for way to reset the Integrate(operand) function

Dan Gray 7 years ago in IQANdesign updated by Joe 5 years ago

I'm trying to use the Integrate(operand) function in a math channel and I would like to be able to reset the function under some circumstances. The only way I can see to do this is to use several lines of qcode. For example:

A:= DerivativeOf(Positon)
B:= Reset
C:= Integrate(Abs(A)) //use absolute value to get total distance traveled
if C = 0 then
D1:=0 //D1 is the starting point
endif
D2:= C //D2 is the end point
D:= D2 - D1 //D is the distance traveled between resets
if B = true then
D1:= C
endif
Result:= D

Is there an easier way to reset the Integrate(operand) function? Perhaps the function could have one or two added arguments, for example Integrate(Operand1, Operand2, Operand3) where Operand 1 is the part to be integrated, Operand 2 is the reset channel, and Operand3 is the reset value?

Thanks,

Dan

### G11 as "optional module"

C. Harp 7 years ago in IQANdesign updated by Evert-Jan 3 years ago

I would like to have the "optional" setting available for the G11 gateway. This will enable the user to unplug the G11 when it isn't needed and the headmaster not throw and error code. If anyone has a workaround for this in the meantime I am interested?

The 'Enabled' property on the G11 does not in fact disable the G11 when set to No.

If you read the tool tip it says

'Select No to disable the communication with the Bluetooth adapter. When disabled, there will be no supervision of e.g. signal quality or lost contact. It will also not be visible in the display menu system. The adapter itself is still operational though and can be used to communicate with the system. To prevent that, see next property Enable Bluetooth.'

So even if the G11 'Enable' is set to 'No' you can still connect and send/receive applications, logs or change settings.

### IQAN Design Finder Function

Nick Pridham 7 years ago in IQANdesign updated by chuck streb 3 years ago

When working on large complex application files written by someone else, finding out about a function is often quite difficult. Take *Brakes* as a search query: Could we have a finder function in the software that could deliver all relevant channels to a finder window with *Brakes* in the channel description?

### disabling error message for a specific output when it's not in use

David Dufour 7 years ago in IQANdesign updated by Gustav Widén (System support) 6 months ago

Hi,

We try to find a way to use a generic program to muliple application.

This implies we will not always use all programmed I/O.

There is a way to deactivate the error detection for the PWM/Cout output on a MC31 module ?

But when it's used, we want this error to be active.

Thanks!

You can put that COUT channel into a function group. And use a digital parameter to enable/disable that function group. By disabling the function group, which contains the PWM/COUT channel, error message will be disabled.

### MD4-10 Graph in scroll mode - slow slider

Florent Mirieu de Labarre 7 years ago in IQANdesign updated by Gustav Widén (System support) 7 years ago

Dear

With this application : https://www.dropbox.com/s/97dws0qe5xak85v/IG29%20V23.01.ida4?dl=0

When you use the graph in scroll mode, the slider and the switcher (on top of screen) move super slowly. But whith the grpah in sweep mode the slider ans switcher works correctly.

### "compare with" does nothing (V4.05 &V4.06)

Jean-Marc Zanni 7 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 7 years ago

I am not sure If I am doing something wrong, but the "Compare with" in the File menu does not seem to do anything? I click on it it opens the File search box, I select the File I want to compare with and Click OPEN button. The dialog closes then nothing... I stay on whatever page was open before. No comparison box shows up. Any special setting?
