changing state when a button needs to be held

mehradhqs 1 year ago in IQANdesign updated by Kerry Brock 1 year ago 1

Hello. I am a beginner in using IQAN and have some issues: 1 - I have created a finite state machine for 2 modes. I have also created some function groups for some functionalities. I want certain function groups to only run in a certain mode and be blocked in the other mode (Like a top level conditional statement). However, apparently function groups do not have the option to be blocked like signals. Is there a way around this? Also, the transition happens while the operator is holding a button (name it A). So during the transition process the operator needs to be holding button A and when the button is left midway the transition is stopped (in this phase do we need an additional state? because it is neither in mode 1 or 2). During the transition between the modes I want to lock all function groups. Finally, the transition can only occur if a certain precondition is satisfied. I cannot seem to break down this problem and do it. 2 - As a final question, I have used some sensors to measure the position of a cylinder, but when I am doing a horizontal path, I need to maintain the same y axis for my end tip of the arm. I have done the kinematic calculations and have assigned vin and the cout, but because the simulation is not in real time, I do not know whether the sensor in the next cycle measuring the position of the end tip really gives a vertical lift path or not? How can I do the simulation continuously to see if my final position at the end of each cycle really have the same y coordinate. These questions might be a bit vague but again I am a beginner and would appreciate any help. thank you in advance for the help.

Handling HEX number in IQAN

Andy Pauly 1 year ago in IQANdesign updated by Gustav Widén (System support) 1 year ago 1

An external CANBUS node is sending Error Number as Hex-Number. The Hex Number is 2Byte long. I like to show the hex in a simple way in the display because page long dokumentation are available already for troubleshooting based on Hex Numbers. 

Is there any way to show Hex-Numbers a simple way?

Is IQAN compatible with UDS communication ?

Dragos Popa 1 year ago in IQANdesign updated 1 year ago 4

Hello, we are thinking of integrating a system that uses UDS CAN communication and we were wondering if IQAN is compatible with this type communication.

Thank you.

Detecting Loss of CAN Communication using GFIN Blocks

JackT 1 year ago in IQANdesign updated by Gustav Widén (System support) 1 year ago 4

Hello,

I am utilizing GFIN to handle incoming CAN messages from a vehicle CAN bus. I am looking at detecting if the IQAN screen has lost communication from the CAN channel it communicates on. I tried using the "Timeout" feature on GFIN, though it seems to have a different definition than the "Timeout" given to the JFIN blocks.

I expect that if the GFIN block does not receive an updated CAN frame within the span of the Timeout value, the GFIN block would return a false pulse. The GFIN block does not seem to react this way. 

If I want to detect if a GFIN block has lost CAN communication, is this the right approach? Or is this not possible to do using the GFIN blocks. Perhaps there is another method I can try? Thanks.

Iqan TALK version

Adrien Léauté 1 year ago 0

Hello,

I renew my question here, how many version of IQAN TALK exist?

mine is Pro version 2.41 and I think the reason why i can connect the machine as the message says in my laptop is because the software is to old so I would like to install a different version of TALK

thanks in advance

screen shots save location

Ed Schippers 1 year ago in IQANsimulate 0

It would be nice if when you make a second screen shot, the save location is the same as the one you used before.

Now every time you make a screen shot you need to navigate to the save location you want to use.

IQANanalyze Not Populating all ID's

ksilovich 1 year ago in IQANanalyze updated by Gustav Widén (System support) 1 year ago 5

In the master list of CAN ID's there are alot of them missing, but if you go to filter a message you will find it. And if you select only that message it will appear then. 

Ex 1218 does not exist when you show all ID's, but if I filter 1218 only then I can get the data.

When you are trying to reverse engineer a CAN bus and need to quickly know all ID's that are being broadcasted on the bus, this is a Major issue.  Spent hours wondering why my CAN router was not working, Its because I am missing ID's that I did not know existed.

IQANdesign 6.08.32 camera update

Camera ISO 17215 compatibility

In IQANdesign, there are two camera modules, the SV camera and Generic camera.

An advantage of using the SV is that more properties can be changed by the application; for example framrate, mirror and flip.

The interface between MD4 and IQAN-SV camera is the standard ISO 17215 (Road vehicles — Video communication interface for cameras), using SOME/IP for communication. 

With IQANdesign 6.08.32, support for this protocol has been improved to make it possible to use cameras from other suppliers in the same way as an IQAN-SV camera.

Previous IQANdesign versions have a problem with downloading via the check for updates function, to update download 6.08 from https://www.iqan.se/downloads.html

Reading position of J1939 joystick

Deanne 1 year ago in IQANdesign 0

Using an old Danfoss JS700 J1939 joystick and having trouble getting a position reading. I believe I have the correct bit parameters assigned, source address, PGN and I am getting a good metered reading on the wiring. I am wondering what other parameters I'm missing.

Why can J1939 Parameters only have lengths of 1 bit, 2 bits, 4 bits, a Byte or 2 or 4 bytes and not any specific bit length?

Andy 1 year ago in IQANdesign updated by Gustav Widén (System support) 1 year ago 3

Can anyone advise why Canbus parameters in Designer can only be 1,2,4 bits or 1, 2 4 bytes in length? I ask in that I have a device that Im connecting to that has parameters of 14 bits, followed by 5 bits then 9 bits lengths  etc because that optimizes their use of the bus for the data types they need. I can of course achieve the same by defining an interim Byte 1 through 8 integer math channel and use heaps of shift left and shift right and band functions to build my own structure.  and then add into byte by byte parameters.

If the parameter channel allowed length of any bit value then we wouldn't have to jump through hoops to build our own structure just let designer do as it does already for the existing options?


Or is there some other SAE standards related reason why that can't be done, in which case the manufacturer of the device Im trying to connect to  must be out of standards?
