We are getting ready to launch a product using IQAN Software. As we make major changes, how can we push them into the field? Without the customer needing to do a lot of work?

We have a MC43FS and MD4

Thank you

Hello,

It would be nice if we could set the date/time automatically through the IQANDesign application. We have a way of getting the current date/time from an external module, there's just no way as far as I know to force the application to sync with that time.

So I imagine it could look something like this

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.

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

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.

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?

I would like to be able to insert a parameter into the column of a lookup table. Is there a work around?

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.

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.
