Calculation Overflow in Math Channel

Bobby 2 years ago in IQANdesign updated 1 year ago 5

I'm trying to use a math channel to do some higher value calculations.  I keep getting a calculation overflow error and it returns a value of 2E09.  I'm assume this is the maximum value for an integer.  But with a real value, the maximum value should be much higher than this.  I would think that I should be getting a real value instead of an integer value.  Is there a way to ensure I'm getting a real value?  Or is something else going on entirely?

Hello, I can't find the settings for adjusting the PWM output frequency on the XC43 as on the XA2 in IqanbDesign, can anyone tell me where I can find it?

Import a clone file to open in script for modification?

pkeough 2 years ago in IQANscript updated by Gustav Widén (System support) 2 years ago 1

Currently have a vehicle fire apparatus that is equipped with the IQAN system. I need to make a minor change as a module is set currently to not active as it was added after the fact and now needs to be set to active. I have the Clone file. Can the clone file be used and imported into script to make the modifications?

Graph functionality

Andy 2 years ago in IQANdesign updated 2 years ago 2

I have a page, one of many on an MD4-10 display, that has a number of graphs on it. The display isn't a page that an Operator will usually use, but if they feels somethings is off, or there was a transient/behavioiur they didn't expect or fully catch enough of to report then they can switch to the graphing page and the graphs currently start rendering in real time.

In my scenario given that transients are generally non repeating (or at least the operator doesn't know enough to cause the repeat to occur), I don't want real time starting from when they went to the page, but rather if the graph timeline is say 5 minutes, then I want the graph at activation to show the last 5 minutes of the measure (and hopefully the event they just felt) and overwrite as usual as if the page had been open for longer than the timeline. Is there anyway I can configure the graphs so that they display history rather than just starting at time 0 on page activation?

In my case all the machine core data is going across a J1939 link to a duplicate display, but it generally only updates 5 times a second for most measures (more often for time critical things like Joystick movements etc) which may not catch a transient. But I could set up a J1939 Data Logger but it would seem a shame to me given that what is in the software almost does what I want anyway?

Any thoughts on how to either configure what I want or to set up a capture solution in design or other approaches people have used?

If this was possible is there some way to stop the graph advance of time with a button so a picture or screen capture can be taken showing the captured behaviour we want before its overwritten or falls off the end?

Having issues to receive a transport protocol message

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

I can not receive messages from 1cEADC00 or 1cEBFF00. My engine is sending this out to identify my MC43 as a valid module to listen to. I must send back a message on EC00.  My MC43 is set with source address 220 or DC. When i set my recieve PGN to 0xEBFF Iqan will change it to as shown

Image 3648

If i set up an out going message to 60160 DA 255 it will send message as 1cEBFF as it should. But i can not receive message from that PGN and the error for invalid identifier never goes away. Why is that?

I have the same issue with 1cEADC00

Hello,

Since I updated IQAN Design to actual version I notice that when connecting IQAN Run (5 and 6, all actual version) the connection Pop-Up shows strange characters at Module Serial Number column, see attached file. 

There are no issues with connectin/uploading/downloading.

Any idea?Example 1.jpg

Current Output Adjust Screen when function parameters used for Min and Max currents

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

When Function Parameters are used as Min and Max currents in a current output in Iqan 4 - they would show as locked in the current output adjust screen.  In Iqan 6 they are not shown as locked and in the screen they can be adjusted but will n ot adjust the function parameters and therefore do not save.  Can we get these Locked symbols and functionality in Iqan 6 as it confuses users.

IQANdesign 6.08.28 did not fix MD4 CAN C & D Issues ?

Matt 2 years ago in IQANdesign updated by Gustav Widén (System support) 1 year ago 6

Hi all. I did some testing on 3 MD4-7s with serial numbers after 2302040001. All of them had issues on bus D not communicating with generic CAN devices. Is this a known issue which has a fix in the works? Is there a PCN newer than PCN7432021-53289-3?

I have tried using programs with 6.08.24 and 6.08.28 and still get the same results.
