COUT configuration for Danfoss PVHC

Deanne 2 years ago in IQANdesign updated 2 years ago 11

Does anyone have experience with programming a Danfoss PVG with PVHC 12V coils? I'm trying to configure with COUTs and PWMs with an MC42 but I keep getting an open load error. Trying to get joysticks to control the current output and I am getting a very small mA reading

Converting CAN Joystick signal

Deanne 2 years ago in IQANdesign updated by Tim Reen 2 years ago 3

I am configuring two 2-axis joysticks. I am able to read the raw CAN signal of the joystick's position. I am wondering if I need to convert this signal further to then control a cylinder (current out). This is what I have so far, but not entirely sure as I am trying to program non-IQAN joysticks.

IQANDesign 6.07 COUT program limit is 1350 mA?

jerry rowe 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 3

Why is the IQANDesign 6.07 COUT limit 1350 mA? 

An MC43 shows 2500 mA limit. How can the current be increased within the program?

JPOUT Hex changing value on the bus

Michael Carlyle 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 1

I am sending a 4 byte Hex JPOUT (0x45564153 starting on bit 33).  When sniffing the bus - the 53 is being sent as 80.  Is there some reason for this?  I changed it to two 2-byte JPOUT's and it seems to work as a workaround.  Is there a problem with how Iqan handles integers in this case?

changing state when a button needs to be held

mehradhqs 2 years ago in IQANdesign updated by Kerry Brock 2 years 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 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years 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 2 years ago in IQANdesign updated 2 years 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 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years 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.

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.
