Reportedly I had a customer who lost the date and time on one of their MD4s after recently flashing a program update (we went from 3.0 to Design 5.0 as part of the update).

Is there any chance this had to do with the update?  I think it's more likely that the real time clock had already failed on this unit and they just discovered it when they did the update as we've had a handful of hardware related issues with the MD4s losing the time saving mechanism in the past.

Below is our system architecture and a photo the customer sent me of the failure. 

Please let me know your thoughts.

How can I save the value of a previous state with the memorizing calculation? I can't seem to figure out what I need to use as my activating to just get the previous value.

Version 5.03 of IQANdesign, IQANsimulate, IQANrun and IQANscript are available on check for updates.

New features

Multimeter in IQANdesign
The free floating quick-measure "Multimeter" window from IQANrun is added in IQANdesign. 
It is possible to bring up the Multimeter window and drag channels to it while measuring, or while editing the application.

Use IQANdesign 5.03.12 for this feature

Graph measure in IQANrun multimeter
It is now possible to add a multimeter measure group to the IQANrun graph measure view by selecting the group or one of its items and clicking the graph
button in the multimeter toolbar. You can then use the same features as when measuring on a regular measure group, such as starting/stopping the measurement, zooming, saving etc.

GT module and telematics node in IQANdesign
A new type of gateway module is added, GT - Gateway Telematics. This represents a generic Parker IQAN Connect gateway supporting IQAN remote diagnostics via IQANconnect and 
telematics; signal collection from the application sent to a server. 

More information on the gateway hardware and the telematics service will follow in the next couple of months. 

Important bug fixed

XC21, XC22 and XC23 inputs frozen after cranking -fixed.
This problem existed in versions 4.07 - 5.02. The master module could freeze all input values of an XC2x if the module had a short dip in power supply,  <9V for tens of ms. The dip had to be short enough to restarte the XC2x whbefore it had timed out in the application. 
Applications with longer cycle times e.g. 50ms were more likely to be affected. 

For more details on 5.03 updates, see release notes

Have you used any bluetooth transmitter / receiver with Iqan? I want to send sensor signal 0-5V to MD4 with bluetooth.

I just found this in the 5.03.11.5029 rev and I would like more information on its capabilities from a software side... or any information would be good. 

Has anyone had any experience connecting a Red Lion Data Station Plus to a MC43? In IQAN 5 I have configured a Generic Can Bus with a Generic Can module and using a GFOUT frame. In the Red Lion I have a CAN card and am using the IQAN driver, but I can't seem to communicate. In Analyze my address shows up as -1 and no contact. I have no idea what to try, if anyone has a working example it would be greatly appreciated.

Hi,

Sometimes I have blue screen on my laptop when I send Project with IQANDesign or IQANRun on a MD3. I tried with many versions (2.63, 5.0, 5.2) and two laptop. 

I just want to know if somebody knows this kind of bugs.

Does anyone have any tips/tricks to break up an external function into multiple files without loosing the I/O and graphic mapping in the main program?

Through lack of fore sight 1 of my external function blocks grew to the point where windows 7 thinks IQAN is no longer responding while updating.

I have made multiple external functions and split up logic in those but I can't find a way to take the existing function blocks in the main program and point them to the newly attached external functions without re-adding the block with all the headache that causes. 

Any pro-tips would be welcome 

Hello,

This may be a trivial question, but ..... it's always better to ask :)

Let's say we have a small project with  MD4 + MC43 - both connected only with Diagnostics bus.

In MC43 application logic we have an Integer parameter channel (IPC: value1) and Digital parameter channel (DPC: value2). Both channels have their own adjust items.

On a display page of MD4 there is IPC: value1 slider and DPC: value2 text button.

My question is why we can adjust IPC: value1 (which is located in the MC43 application logic) from MD4 display, but we can't change the state of DPC: value2 with text button?

You can do it with a switch on a display page but you can't with a text button.

Thanks in advance.
