Machine Number Identification

Alex 9 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 9 years ago 1

Hello,


Recently I had an issue where code meant for machine A was uploaded onto machine B, and machine B was able to halfway function. To prevent this issue in the future, I want to have some sort of identifier that the MD4 or MDL2 can read and either continue running or throw a message saying "Incompatible Code" and quit.

So far I have thought of a few possible solutions. If possible, I would like to do this over CANbus so I don't use up input pins.Ideally, it would be nice to have a module that broadcasts a serial number or identifier over CANbus that the MD4 can read and compare to a list of acceptable machines. Another idea would be to have the MD4 check a certain "identifier" module's address and only run the code if it can find it. Worse case scenario, we can use some sort of hardware tag, like a resistor, to send a voltage to one of the input pins.

Since I am a novice with IQAN software, I am curious if you have any better ways to do this. How would I implement such a feature?

Thanks for any help, I appreciate it!

Array issues / improvements

Rick 9 years ago in IQANdesign updated by Mack 1 year ago 5

Since there are no DM1/DM2 blocks to send out 1 or more faults yet, (hint!), I'm trying to implement it myself, using Array blocks. It works, BUT:

- No Array support on MC3 (for safety reasons? why?)

- No looping or "Add" functions to construct the list dynamically

- Arrays are Float by nature. This is inaccurate for 32 bit UINT DTC codes. Would be nice to have a integer (and if doing it anyway, a boolean) variant

- Ability to fill/insert/operate an Array from another block ("adding itself to the list")

Biggest problem is the MC3, where more than 50% of the CPU is currently spend on sending out DM1 & 2 messages. Which is obviously way overkill, but I don't see ways to do it more efficiently with the available tools.

Select multiple channels in IQANrun

DavidH 10 years ago in IQANrun updated 8 years ago 10
Is there be a way to select multiple measure items while viewing measure group data in IQANrun using left mouse and shift or ctrl keys? When I want to isolate just a few items, or turn all on or off, I have to pick each one at a time.

SAE J1939 TSC1

Zach Dockter 10 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 9 years ago 8

Is there a way to set the J1939 Source Address field in the TSC1 command to an Integer Parameter? That was we can install the same crane software on different truck chassis with different engines.
Cummins/PACCAR like to use SA 7 for TSC1 control. Detroit Diesel likes to use SA 231. It would be nice to allow the J1939 SA field to look at an integer parameter and adjust the code accordingly.

Idea: ​Ability to change TP channel value using Qcode

Tuomas 10 years ago in IQANdesign updated by Nick Pridham 10 years ago 4

Ability to change TP channel value using Qcode like:


if VDIN-Choice1 = true then TP1 := "Your choice value is:" + MAC-value1 + " that is under the limit"


If VDIN-Choice2 = true then TP1 := "Your choice value is:" + MAC-value2 + " that is over the limit

IQANrun takes the first step to mobile devices. With this free version you can perform some basic functions like, viewing system status, logs, measure and adjust.
Today the app works with IQAN-MD4 and basically it allows you to do the same things as you can do in the IQAN-MD4 systems menu.
Future releases will come with Android versions and Pro versions will include more functionality such as SW update, settings viewer, save logs and graph measure.

Please see the attached presentation and press release for additional information.

J1939 at 500kbps

Frederick Prigge 10 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 10 years ago 3
Hi, I am seeing more and more components that run J1939 at 500kbps. I know the specification says it is fixed at 250, but some engine controllers and some hybrid components are now requiring 500kbps. In IQAN design this particular CANbus type has a fixed baud rate, you cannot change it. For now I have to hardcode 29bits messages and use geneic CAN busses to talk to these components, but without all the added benefits of using your "real" J1939 implementation.

Please add selectable baud rate for J1939 busses as well.

Thanks for your great product.

JFOUT multi-packet for handling text strings

Nick Pridham 11 years ago in IQANdesign updated by Gustav Widén (System support) 1 year ago 12

I have an application where I want to send text strings over CAN on a very occasional basis. A tool for handling extended outgoing CAN frames for this task would be very useful.

Please include an auto ASCII converter in the tool.
