MD4-7 blue screen
Hi, sometimes at start up a blue screen appears and the system does not boot.
any ideas?
J1939 Error - Caterpillar ECM
Communication with Caterpillar ECM over J1939.
When the machine control system is first powered up, and the engine is not running, the System Log logs several J1939 events related to a couple of PGNs.
Has anyone else seen this before?
I don't believe it is the PGN timeout, as there are several ECM PGNs with timeouts that don't log errors.
Anyone have any idea what "J1939 Error" Means?
Thanks!
As you can see, there are five J1939 errors that consistently show up on power cycle.
One of them is Engine Oil Pressure. Here is the PGN:
And the associated PIN:
MD4 Graphics Options
Another nice option would be to be able to fill in areas bounded by lines with blocks of colour which could be selectable by another channel. I know that this is possible by creating colour images and then imputing them but this would be a much easier method.
Another thing which we seem to get requests for regularly is the ability to graph items on screen. I have asked whether this might be possible before but up til now this functionality has always been too video processor hungry - I wonder if the new spec of the MD4 might now be able to cope with it?
Visual compare tool
Because for big project the text files compare is difficult to use.
application input output vs j1939 input output for master modules
If I understood it correctly, an MC2 master received a digital value from an MD4 master module via an application in/out pair.
Then in another location in the program, the MD3 and MD4 exchanged information through J1939 pgns.
How do I know when to use Application in/out or J1939 in/out?
Md4 and frequency
Hello
It is possible to measure a frequency with a md4 ?
Thank
360° Rotation of Gauges
I have an application where I am using a gauge to display the position of a rotating object. I make the 12 o'clock position the 0° point. I noticed that as my input is rotating from clockwise, that the needle on the gauge rotates counter clockwise from 359° back to 0°.
It would be nice to have the gauge continue to rotate in a clockwise direction as my input crosses the 0° threshold.
IQANdesign 7.04 QtContainer.dll contains a virus?
Our antivirus keeps deleting QtContainer.dll and when I disable the antivirus and run IQANdesign this message pops up when trying to view an MD4 display page.
Reinstalling with a fresh installer downloaded from https://www.iqan.se/downloads.html has the same issue.
Want to make J1939 bus speed selectable via adjust item for a bus that has multiple masters connected
I have a MD5-5 and MC41 in a system with a J1939 bus connected to both masters. When I select an integer parameter channel to select between 250 and 500 kbps, it creates an error. The channel is located in an Initialization function group. If I remove the connection of the J1939 bus from one of the master modules the error is not generated. Is there a limitation to only being able to have one IQAN master connected? I have tried this with 7.04 and 7.05 with the same result. In the pic below, if I hover over the red diamond it says "Speed not supported."
Autosar CRC
Hello, Im trying to setup a CRC channel to communicate with a Battery system. I can not get the right setup to match their values for the Autosar CRC
IM not familiar with the CRC channel but when I set it to 0x2F with a 0xff seed this is what i get:
