Help!!!

I have been working all morning on a sequential application and on doing a save - Iqandesign has completely frozen and eventually crashed windows!

Unfortunately I made the fatal error of not pressing the save button frequently enough and so the only live file on my machine is the one I started with at 8.30 this morning!!

There is a backup file which appears to be from just before the crash but when I try to open it Iqan is telling me that it was made by a previous version of Iqandesign 4

Is there any way of finding out which version and is it possible to download older versions - I can't find them on the parker website - only the latest version.

I'm trying to select from two different inputs to drive the one output, using a joystick for travel mode input and a potentiometer for sweep mode input. IAny ideas or any programming examples.

Is there a method available to protect, via pin code access, changing the time and date entry via preference date/time display page in an MD3?

We have been experiencing issues with operators on one of our end-user sites with our mobile equipment. We have implemented a method of tracking the operator that is currently using the equipment via a terminal access key value being transmitted to the MD3 over J1939 bus and then capturing the data via event logs. The events are time/date stamped, works well. The new issue we are experiencing is that the operators are now manipulating the system time and date and I would like to inhibit them from being able to do so.

We have a machine in the field running 3.19 and we need to update the software remotely. To avoid updating the firmware (it takes too long and sometimes fails half way though updating) i need to revise the software using the correct version of IQAN Design originally installed on the machine. The machine appears to be running on firmware version 3.19.9.3143 in the MD3 and 3.19.9.2170 in the MC3. This is a multi master system.

Can anyone confirm which version of 3.19 I need to build the software change into to prevent having to update the firmware in the machine please? There are multiple versions of 3.19.9 and if I choose the incorrect one it will update the firmware.

I have tried to simulate 3.19.7 and 3.19.9 and use IQAN Run 3.19 to look at the firmware revision but the firmware does not appear to match what we have running in the machine. When I simulate I get 3.19.2.

Is there a list of supported DLA devices for IQANanalyze?

My problem is I am trying to connect to a 500k CAN network.. The Vansco DLA is only supported of the 250k (or at least that is all I can get it to work on), so I need an adapter that will work with analyze and a 500k CAN systems. I have a Dearborne DPA5, but I cannot get IQAN to recognize it.

Any suggestions?

I have an application where I am using an Intellinder cylinder that has the position feedback. I need to be able to allow the user to input the value of the position that he wants the cylinder to go to (extend or retract) and then execute the movement through a PID loop. I am having difficulty with the user input of "ending" position. The precision can be up to 0.01". I can use an adjust item to input the value, but I don't see a way for the default value to read the current cylinder position nor do I see a way to have the adjust item display on the home page instead of in the adjust sub-menu. Any thoughts, ideas, etc. are greatly appreciated. I could use some urgent help desperately.

Thanks

I just updated to the Version 4.02.5.3440 and I'm unable now to see the start page on the screen. The only thing I have is the version number on the bottom right of the panel.

It work with a MD3 program.

To do the test, I use the demo program from Parker.

The MD3 demos work correctly, but all MD4 demos won't.

IQAN-MC2 modules older than the MC2-M14 will stop and show an internal error blink code if running version 4.02.13 and connecting via USB. Some more details about this problem were posted here a couple of days ago:

An update to resolve this issue is now released on check for updates.

By any chance are there any examples of using the derivative function?

I am trying to measure the gallons per min of a water pump we have. In the pump there is a linear (0.5v to 4.5v) sensor. So I am trying to use the derivative function to calculate the in/sec at which the sensor is traveling to calculate the GPM. In addition to just reading the in/sec I need to know in which direction the sensor is moving, because the amount of water is different on the return stroke due to the rod diameter.

I am currently using the derivative, but the issue I am facing is that when I am reading the sensor and applying the derivative the value is very finicky (jumps around alot) and if I apply any sort of filter to the sensor input the calculated flow lags the actual flow too much for our application.

Hello,

I need to directly display a screen (ex:screen 4 out of screen 10) based on a condition.

Ex:

Particular Case: Consider i had used MD3 display and switching it ON again after 3 hours of gap. during this case the display should prompt user to view screen 4 directly instead of showing screen 1.

Normal Case: Consider i had used MD3 display and switching it ON again after 1 hour of gap. during this case the display should prompt user to view screen 1 (which is normal) as per my sequence.

Thanks,
