A release update to 7.02 is now available, IQANdesign 7.02.33

MD4

This version has a bug fix update for IQAN-MD4, we found and fixed an old issue where bursts of errors on CAN could lead to an MD4 watchdog reset. It is very unusual to be seeing this symptom even on machines with problematic CAN installations. But over the years there have been a number of events that can now be explained, and avoided by updating.

Hello,

I am trying to run a Mitsubishi VFD that takes a current input of 4-20mA to change what hz the connected motor is running at. The VFD says it's not receiving a current command.

I see this excerpt in the manual:

Minimum current
There are several diagnostics methods that are active, one of these methods is based on
measuring current. The threshold for detection has been selected based on the
assumptions that currents below specified minimum current does not cause movement.
Error detection limits and delay
The COUT has two separate measurements of current, and is capable of detecting drift
faults on the closed loop control of the output. To avoid spurious trips, it is designed to
tolerate some deviation. The worst-case detection time for the most severe type of
faults are listed in the table below:
Since the MC4xFS COUT channels are grouped in pairs sharing an internal high-side
driver channel, shutdown of one COUT will cause shutdown of both COUT channels
in the pair. Restart conditions are controlled by the application.
Appendix B has detailed lists of failure modes focused on output wiring faults.
C4x-SMR-027:A Minimum current when using COUT
Safety related output functions controlled by COUT shall be designed so that
movement can only be activated if the output current is > 100 mA. 

Maybe I'm misunderstanding, but if the minimum current is 100mA, why does it let me set a COUT range of 4-20mA without throwing an error?

The USB interfaces page mention Kvaser Leaf as being a supposed USB to CAN interface, but is the Kvaser BlackBird v2 (https://kvaser.com/product/kvaser-blackbird-v2/) fully supported as well?  I have one that I can get to work with IQANanalyze but it can't find a master module to connect with when used in Design.  It is recognized as an interface under Tools>Options>Communication as a CAN adapter but I an error message when trying to connect (see screenshots below)

Sometimes using a dual object as a limiter on a dual direction math it does not store the value entered. Not sure if its the same on other functions.

Enter value into Out 1 then hit down key rather than return key and the value fails to store although appears to be saved in the property section.

Enter value into Out 2 then hit up key the value fails to store.

Clicking off the channel in the main workspace and then reselecting it shows it has not remembered the value you entered in property section, and instead goes with the value shown at the bottom of the page.

I had multiple instances where I thought I entered a value and found it had not stored correctly, but seems intermittent, made worse if you key down to Out 1 (to enter a value) from the 'input' selected (highlighted) first rather than using the mouse.

IQAN Design 7.02.

It would be a nice addition to the MD5 family if we had option to upload/update programs via onboard USB port. Rather than relaying on proper cell coverage we could simply email the file and have the end user push an update via the USB port. It appears to me that most of other controllers have that feature build in. 

Is there a way to log decimal numbers in the event log? The values I have now are stored as whole numbers with ".00" after even through the actual channel they were reading has decimals. For example, a channel value of 5.4 is logged as 5.00.

I have a function parameter with a step size of 50 that the user can adjust. This is working fine when they use the + or - to adjust the value, but when they bring up the keypad (MD4) it is allowing them to enter values outside of the specified step size. Is there anyway to fix this?

Design Issue 7.02.31.9477: When adding a lamp component from the stock image library, the system does not permit the selection of an "off" image from the same library.

When monitoring a slower frequency input, less than 50 HZ, is there a way to achieve better resolution that 1 HZ? 

The frequency input channel itself appears to be a float variable as it displays two zeros after the decimal point. 

The application I am working on the frequency signal range is approx. 7.48 Hz to 16.72 Hz.  The two extra decimal places would be extremely helpful in calculating an accurate speed.  In most situations I would suggest to increase the number of pulses per revolution to increase the frequency reading, but in this situation it is not possible. 

Is increasing the resolution of this channel something that can be implemented?

Sometimes it is useful to plot variables as functions of other variables rather than time, e.g. cylinder velocity as function of joystick signal.
