trouble to receive Muxed Can messages

Codie 5 years ago in IQANdesign updated 5 years ago 4

Hello, I am using a MD4 to receive CAN message from and Inverter and the Can messages  are Muxed. So i have my application designed to receive the J1939 message and the first byte is the command bite it should then change a state machine in which allocates the data to the associated memory channel while in that state. What I'm finding is my command byte is changing but to fast to acknowledge. I have a can trace and i can see the multiple different messages of the same message being sent at different rates and with different priorities but my  command byte is not changing the state machine. Occasionally i get a value that has been received from a different command byte so the program must have worked but its very random. It reads the values sent at 10 ms and ignores the other messages with a longer send rate most of the time. Would yo have a suggestion on how to delay the time that receives the command byte in order to allow the memorizing channels to save. Or any suggestions for Muxed messages. File is attached below can trace

Reset modules over remote connection

Neeraj Chirmulay 5 years ago in IQANrun updated by Gustav Widén (System support) 5 years ago 1

Hello,
Is there a (currently or planned) feature to allow a remotely connected user (logged in with the right privileges, of course) to reset the system/ cycle power? The modules reset when you send a project, or send settings, but there doesn't seem to be a way to reset the modules after manually adjusting any parameters.
This would be especially useful when adjusting "Initialization" parameters that require a reset to take effect.

Problem updating Firmware (via Kvaser CAN adapter)

Rick 5 years ago in IQANdesign updated by Gustav Widén (System support) 9 months ago 6

Last weeks, we are having issues updating MC41 modules via USB-CAN (and some of our service guys told having the same issues with a MC42, but that is unconfirmed). It seems the  "Updating Firmware" step takes forever. Eventually we succeeded with one laptop, but it took ~20 minutes, where it would normally take 1 or 2 minutes at most.

Other attempts would result in a "No reply from master module" failure. And what seems to be strange: we tried to upload with IQAN 5.03 but the failure message said it failed uploading Firmware version 6.00.48. So we tried again with IQAN 6.00.48, and the upload was done within a flash... But strange enough, I couldn't upload the same (IQAN Design 6.00.48) program earlier on another MC41. It would also get stuck at the Update Firmware part, and then the older 5.03 version would upload the program without problems...

So we have this issue with both IQAN Design 5.03 and 6.00.48. Tried several laptops, but that didn't make a difference either.  Using the same KVaser LEAF Light cable as always.

The strange thing is, we have been using IQAN Design 5.03 and 6.00.48 for quite a long time, without having issues. It recently started. To me, it sounds as if something changed on the hardware, or maybe some Windows (10) update is causing trouble.

can't copy and paste into IQAN Design version 6.02

Mike G 5 years ago in IQANdesign updated by Gustav Widén (System support) 5 years ago 5

It is not possible to copy code or function groups from previous versions of IQAN design and paste them into version 6.02.  I have verified this with versions 5.04 and 6.01.

set VDIN to true on startup

Codie 5 years ago in IQANdesign updated 5 years ago 2

Is there a way to set a VDIN to true on startup. I have several mode selections on my MD4 and i would like it to default to one of them.  There is no way i am aware of to set the VDIN true from an internal digital or anything other then touching the screen.

Password Database File Import/Export On The Same Computer

Nick Pridham 5 years ago updated by Gustav Widén (System support) 5 years ago 1

Is there any way of importing/exporting a password database file on the same computer ? I have a scenario whereby 50 field service engineers have a database with safe password keys only. When we come to upgrade IQAN versions, new keys have to be manually generated because the public key changes.  Could the IQAN team think of:


Keeping the public key the same so that new safe keys do  not have to be regenerated ?

OR

Supporting some sort of local import/export use case for the password database ?

Hi all,

Is there a way we could rotate images on an MD4 from the center of the image. The current setting rotates from top left?

Can you display 2 cameras on one MD4 at the same time, like a split screen?

J1939 Comms Between masters

Carl 5 years ago in IQANdesign updated by Gustav Widén (System support) 5 years ago 1

Hi Guys,

Is it still the case that if you have multi PLC's say MD4, MC41, MC42 that to transmit from say the MD4 to the MC42, you have to create a J1939 Generic device copy of each module or is there a better way now? Also, if say we have the engine connected to the MC42 but want to read some engine CAN messages on the MD4, is there an easy way or lots of JPOUTs and JPINS between modules?

How decrement with variable vector function

claudio 5 years ago in IQANdesign updated by Thomas Moberg (System support) 5 years ago 1

Good morning, in a lifting machine controlled by an MC43, in the software I made counters to decrease the hours of life. Now I have to link this decrease to how much weight I'm moving. I read the weight from can open and turn it into a vector function Then with this I should vary the amount of time in percentage of the weight. That is, with weight 100% decrease 1, with weight 10% decrease 0.1. The question is which function can I use to perform this function?
