Is it possible to limit an Event counter channel with a maximum and a minimum value?

Do I have to connect the ID-Tag to my Master module even though I'm using only one master module MD4 and one expansion XA2 will be connected to it, can anyone help me with this?

Thanks 

When I upgraded to IQANDesign 5.04 from 5.03 my project now has 1183 errors, with 99% of them being 'Invalid Context'. I can't seem to find a pattern as to what is wrong with particular snips of code.

Here is one example.

Would like a use Internal Digital in to select different PDFs based on some internal criteria or selections of the type of machine.

IQAN Design 5.04

I have an application file which I have prepared for Telematics using the new Telematics Functionality in "Diagnostics"

-I want to fit a G3 modem. A permanent connection is required and GT is not avail just yet.

-The application file check generates an error if a G3 and GT gateway module is added. - (Too Many Modules Of The Same Type)

The application file check generates an error if a just a G3 gateway module is added.(Missing Gateway Module with Telematics Support)

Can the IQAN team suggest a work around ?  I would like to leave the Telematics message config dormant until GT gets up and running. Can a change be made to IQAN Design so that GT and G3 can live in the same application file for the time being.

BTW - I have tried playing around with the "Enabled" property for both Gateway Modules and the error is still flagged by the application file check.

Hello,

I'm trying to implement gear change using buttons (D, R and N). When the user press the button, it will ask for confirmation to prevent miss click, if "Yes" it will send CAN message and active gear, if "No" do nothing.

I implemented this latch to hold the value of D, R and N gear (if true or false after interactive message).

But the thing is, I want to keep only one gear active at a time, for example D=True,R=False and N=False. How I can manage to turn off other variables inside Qcode?

Thanks!

Hi,

I am running a test bench with only some of the components connected to the MD4 display. In the field, their is a XC23 and 3 other CAN buses connected with multiple devices.

I am validating one of the device on the canbus B. When I start a measure with IQANDesign with the display connected via Internet and go in the function group where the CAN messages are received, the MD4 display crashes and a blue screen appears (see screenshots bellow). This function group receives 4 messages and convert it to 25 signals used in state parameters and math channels.

Busloads during crash and startup is bellow 5%.

Cycle utilisation is bellow 50%.

Cycle time is 10 ms.

We successfully run IQAN Design 4.07.15.4769 on our systems. This is the only occurrence where we see this problem and I am wondering the root cause.

What am I not seeing?

I wish there was an efficient method for importing graphics into the design environment.  It would be nice to have project files dedicated to certain functions (i.e. diesel control) complete with graphics pages linked to channels.  Building larger applications would be much easier if it were possible to import those project files, complete with linked graphics pages, in such a way that an existing display module could be selected as the destination for the application and graphics pages; similar to external functions.  It would save a lot of time and make managing applications easier.

If there is a method I am not aware of, please someone speak up.  As of now, I copy the graphics and function groups from one application to another, but then have to re-link all the dynamic graphics and images.  It can be a real pain and is time consuming.

I'm writing more of my program with Qcode, and ran across something this morning that might help someone else:

I was trying to get an IDC to latch on with a momentary, rising edge signal, and then stay on when the signal goes off. Easy,  using object list and a "latching or/and" 

But, when I write what I thought was an equivalent statement in Qcode, the ICD functions as a momentary, and doesn't latch:

Obviously, this is a bad programming practice, because in just about any other structured text programming language, the IDC would become stuck on the first time the input went true, and would never turn off. However, that's NOT what it does. Try it for yourself; when the input goes false, the IDC also goes false, acting like this:

I don't think that those previous two code statements are equivalent, but I guess that's just an IQAN idiosyncrasy. So here's a work-around I came up with using a memorizing channel. It works as advertised as a latching IDC: when the input goes true, the MR channel latches on, and then when a different input goes true, the MR latches off:

Note the use of the ALWAYS TRUE IDC. As it's name suggests, it has a TRUE operator in it's activating channel so that it's always on. This allows the MR to latch to true.

So there you have it, a latching "IDC" in Qcode.

Hi all,

Sorry I'm very new to IQAN, I want to add button, and when it is pressed send CAN message.

Where I can find tutorials on how to implement this action? I could add the button but I dont know how to link with specific CAN message.

Best.

Vinicius.
