MC42 PWM HS+LS output overload

Jesse B 2 months ago in IQANdesign updated by Thomas Moberg (System support) 2 weeks ago 3

Does the MC42 perform an active LS diagnostic on PWM HS+LS outputs during startup, even when the application function group is disabled? We receive a Critical Overload on C1:39 with a SPAL ABL321P PWM output. Delaying the physical connection of the PWM wire until after startup completely eliminates the fault.

According to the manual, Appendix B (page 122) states that the check for an HS or LS short to the battery during startup has no contact? Or am I misunderstanding this?
Yet it does happen....

Can't adjust PIN protected items; IQANrun 6.08.27

Mark Bevington 2 months ago in IQANrun updated 2 months ago 3

I have an app that was created in IQANdesign 6.08.32.  It has multiple adjust groups.  Each group is protected by a PIN according to whom should have access to the adjust items that have been included in the groups; MAINTENANCE & ENGINEERING. The PIN's are defined in the HeadMaster a MD4-5(0) with the majority of the Adjust Items in one of two MC43's; MC43FS(1) or MC43(2)


I'm using IQANrun 6.08.27 and can not  make any adjustments to any adjust items.  The PIN is accepted and allows me to see the Adjust Items, but always gives me a "operation was rejected by the remote system" while posting a dialog box that it is "storing parameters" simultaneously to where the fault occurs.

What is going on here?  How do I fix this?

Dedicated Quick Close Menu Command

Leighton 2 months ago in IQANdesign 0

I've liked how pressing the Menu Button while in the Menu will open option menus in the Measure groups and such, and that a long press of the menu button will close the menu entirely, and was wondering if it would be at all possible to separate those two commands? As currently I am unable to create any sort of hotkey, such as a button that takes you to the home screen from wherever you may be, without losing the ability to open the raw vs scaled value option in the measure groups

XC22 Canbus Baudrate Change

chuck streb 3 months ago in IQANdesign updated by Thomas Moberg (System support) 3 months ago 1

We are having issues with the canbus as we have unusual routing.

We are connecting MC43 to (2) XC22 with correct terminations. The 250kb default is working for most of our products out in the field but some are marginal. The only real way for us to fix the problem given hardware LOCK is to lower the speed to 125kb. BUT there is no option for speed changing.  Would it be possible ???

is it possible to send firmware without a project file?

705David 3 months ago in IQANrun updated 3 months ago 7

I recently ran into a scenario where I could not update the firmware on a module because my project file was IQAN 7.06 and the module was 7.04. The Module needed to be updated to 7.05 before it could be updated to 7.06.

Image 5357

This has never been an issue for me in the past. Usually the latest firmware would always load without having to load the intermediate firmwares. I simply created a blank project with the masters in the system at 7.05 and loaded it to 7.05, then loaded the project to 7.06. However this problem becomes much more difficult when issuing program changes to the field. I never released software to the field with 7.05, so the service technicians won't be able to update a system in this scenario.

I looked around in IQANRun and I didn't see any way to update the modules without a project file. Is there any way this can be done?

How to detect Short & Long press of a push button

Jaya Cherlavancha 3 months ago in IQANdesign updated by Thomas Moberg (System support) 3 months ago 2

We need to implement a push button with a dual function, 

To achieve that, we would like to sense short press, long press, and the double or triple press of the push button,

Kindly let me know how to configure a push button in such a way

CIN High Error

RichG 3 months ago in IQANdesign updated 2 months ago 2

I'm using a CIN input to monitor a 4-20 mA signal. I have the Calibration set to {4000; 15000; 0; 137.5} Per the manual, the Error Value should result at the 'Illegal Value' point. For a Low Error, this occurs at 2 mA as expected. I assumed the Max input value to be 20 mA, and my Max value is set to 15 mA. The halfway point between them is 17.5 mA. For some reason the High Error condition is not happening. Am I using the wrong signal max value of 20 mA? If so, what should that value be?

In contrast, the Low and High Error points for a VIN are working exactly as expected when using a Vin Max of 5 Vdc.

I've found this to be true for both IQANsimulate and the actual hardware.

I'm using an MC43FS and IQANdesign 7.06.22.11482.

Adjusting settings on module after login from iQAN Design?

Matt 3 months ago in IQANdesign updated 3 months ago 2

Is there a way to change values in adjust groups that are protected by user logins from iQAN Design after logging into the module using Design? I would have figured that once you logged in with Design (or Run) that the adjust group would appear in the system menu of the display module.

I'm working with Design 7.06 on a MD5.
