Redundant CANBus utilization

Greg R 2 years ago in IQANdesign 0

Some components have redundant CANBus inputs. IQAN can use these by having multiple CAN outputs assigned to different CANbus. It would be nice to have a built in function that could swap an output to a different bus automatically on bus failure or using a logic input.

Ambiguous module address

Ed Schippers 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 3

In a program, I always used multiple expansion modules with the same address with no problem.

this to select for different output setups (COUT instead of DOUT and so). via a setting one of the modules was enabled.

physically there is only 1 module but by enabling one or the other in the program is was possible to switch between the different setups

in Design 6.x this not possible anymore because it generates an Ambiguous address error.

any suggestion the deal with this

regards Ed

COUT Disable Bug?

Chris Litwin 2 years ago in IQANdesign updated 2 years ago 4

IQANdesign 6.04.9.5943

MD4-7 & XC43

I just diagnosed what I think is a bug for the current outputs. I have a COUT going to the max positive value, then while the COUT is at max, the channel gets disabled. When the channel is enabled again it turns on by itself at the previous value where it was disabled at. The length of time it stays at the previous value is affected by the ramp settings.

In my opinion the COUT should zero itself when disabled since that is the safe state.

Is there a way to vary the transmit rate of a JFOUT channel that is in an External Function Group?

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

I can vary the transmit rate of the JFOUT channel with an integer parameter in an initialization group but I am not sure how to do this when the JFOUT channel is in an external function group. I do not see a way to use a constant channel in an external function group and have it point to the transmit rate. Any suggestions?

MDGN Red Stop Lamp Channel Not Clearing

Justin Wagner 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 13

We have a machine with remote control that we need to be able to cycle ECU power to clear active DTCs, while keeping our IQAN control system powered on, using a digital output with relay to control how long the power is disconnected from the ECU (essentially acting as a keyswitch).


After a 10 second power cycle to our engine ECU (John Deere) to clear active DTCs being broadcast on the DM1 channel, and allow for engine rolldown if it's running, the DM1 channel goes back to 0, indicating no active DTCs, yet the MDGN Red Stop Lamp channel is true (see image). As I understand it, the lamp status is part of the DM1 message. So if there is no DM1 message being broadcast, how is the value of this Module Diagnostic Channel still reading true???


Is the MDGN lamp status not read from the DM1 message? How is the MDGN Red Stop Lamp status read? Why does the amber warning lamp not come back on if the red stop lamp does?

The engine still starts and runs, which it would not do if there were an actual Red Stop Lamp event occurring.


When cycling power to the ECU and the MD4 at the same time, the red stop lamp does not come back on and all active DTCs are cleared

I really like the addition of the lamp flashing option, it would be very useful for Tier IV engine applications, but this MDGN is just not acting how I expected it to.


Any help would be much appreciated.

MD4 GUI crash with Gauge inside group

Pierre Fagrell 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 3

I have an MD4-7 application with a gauge inside a group. It does not matter if there are other things inside the group or just the gauge.

As soon as the MD4 boots it will stop at the boot logo, the rest of the GUI will not load.

Also it is not possible to send a new application while the logo is displayed unless you first "Start measurement".


Simulator crashes also with error 80000003

I will send in a bug report from the simulator aswell.

Get external Function files from Hardware

Emerson 2 years ago in IQANdesign updated by Pawel Pekala 2 years ago 3

Hello,

Is there a way to get each external function as an "idex file" from a MC43(FS)? It would be nice to implement this capability if it doesn't exist.


Consider a project with five files (mainlogic.idax, joystick.idex, steering.idex, powertrain.idex, and transmission.idex);

"Get Project" only return mainlogic.idax with missing external file warnings.   

See below for some contextual information.

1. From IQANdesign 6.06, I executed "Get Project" on a legacy MC43(FS). When I opened the retrieved project, the warning "Missing External Files" was displayed. From the project manager (on the left), if I click "External Functions," metadata such as Name, Order, Status, File version, Description,  and file paths of each external function is displayed. However, the individual files cannot be found. 

2. From the application logic, I can browse to each external function instance, but the background is grayed out. 

I am in a situation where the original design is only on a legacy MC43(FS).How can I extract these external functions in their original format?  I would like to reuse them in other projects. Any suggestions or work around will be greatly appreciated. 

Regards,

Emerson

COUT with Date and Time not set on MD4-7

Joe 2 years ago in IQANdesign updated by Benjamin 2 years ago 3

This seems very far-fetched, but I have to ask the question as we have a customer and one of our own service personnel telling us this. The machine in question works for a bit, then may sit for weeks. The RTC is not wired directly to the battery, but rather on the machine side of the battery disconnect. When the machine sits for a long period, the RTC is lost. The issue is that we have a COUT (on an XA2) that is inoperable on startup and the 'Date and Time not set' message appears on the screen. After the date and time are set, the COUT becomes operable. I don't see how these two things could be related, but they are insistent. Anyone else seen something like this?

symbol button control

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

Hello, I would like to keep a Symbol Butoon Control switch on when I push on it twice.
My problem is on the second push. At this time the button switch off and I want to keep it switch on.
The reset is done by a push on a second button. Thanks.
