If a customer purchases a license for Design 5 (only, not developer suite), should the license key work for creative studio 4, 3, 2?

He needs Design functionality in old programs as well.

We have 3 master modules connected according to image above...

We send a P-brake apply command according to the image above. One goes out through the APPO_PbrakeRelease channel supposedly through the "Master" CAN-connection. The other goes out as a Generic CAN-signal through the "Generic" CAN-connection...

The APPO_PbrakeRelease channel is configured as shown in the image above. 1s transmission rate or on change.

On the receiving side, the input is controlling a digital output. The value of this digital output is also transmitted on the "Generic" bus. In other words, on the "Generic" bus we can see the value that should be sent out through the APPO_PbrakeRelease channel as well as the value that is received on the APPO_PbrakeRelease channel...

The problem is, occasionally we see a glitch as the one above. The value that is sent is constantly HIGH, while the value received goes low for exactly 1s and then goes high again. We have seen this for other digital "Application OUTPUT/INPUT" channels as well.

The fact that the time (1s) perfectly matches the outgoing transmission rate configured at the sender leads to the conclusions that one CAN transmission is corrupted and that the following transmission, 1s later, is correct and again sets the correct value. If it had been an actual change of the input signal, then I assume the APPO_PbrakeRelease signal would have been sent again as soon as the input changed back again?

Also, that the "Generic" CAN-transmissions which has a transmission rate of 20ms, doesn't show any incorrect values limits the error to the "Master" bus only. We have so far not seen any similar behavior on the "Generic" bus.

The "Generic" bus is connected to CAN-bus logging device that records every CAN-bus message transmitted without any filtering or "sampling interval". So, if we can't see any change of the signal here, then no such signal has been sent on the bus.

Is it a known problem "Application OUTPUT/INPUT" signals can get corrupted? And more importantly, how does one handle this?

I´m working with an MD3-JS console. The product information is:

Production date: 17/04/13

Software version: 2.60.25.2059

Bios version 1.03

Serial number: 317040111

What version of  IQAN Creative Studio do i ned to work on it?

Kind of a funny issue. We have a large external function library that causes the external function drop down list to drop below the Windows task bar. This makes the last option unreachable unless i move the taskbar. 

One of my customers has used an MD4 on their hydraulic test system where they are driving a hydraulic fan and reading its speed with a frequency input channel.

In the future, they want to use different fans which will mean they need to change the working parameters of the channel (Max and Scaled Max values) and they need to change the values without changing the software.

I cannot find a way to do this at the moment, as FIN properties don't seem to accept integer parameters as inputs, nor can the channels be added to Adjust Items / Groups. 

Is there a reason this is not possible, even though many different IO channels can be added to adjust groups?

We are working on an application where we are required to be able to allow parallel operation of a solenoid valve. i.e. to be able to energise the solenoid via external means at times. We had been intending to get around the error detection problems by placing these outputs into a function group which we disable when the external energising  happens. This seems to work fine for open load detection, however overload still seem to be detected even when the channel is not enabled -is this intended or is it a bug?

We have an MD4 connected to a CAN Open angle sensor. Normally we change SDO objects in the directory using a CAN tool (for resolution, heartbeats etc). 

Ideally we wanted the MD4 to configure these parameters instead of using the handheld programmer, does anyone have experience of this, or perhaps can suggest a way of changing the parameter below from 1d to 1000d?

I have two parameters, a digital parameter and a function parameter that is adjustable via MD3 and I need that whenever my digital parameter is false the value of the function parameter returns to zero and after the digital parameter returns to true the value of the function parameter will be maintained at zero only being changed via MD3 again. It's possible ?

Some of the graphics have disappeared from an MD4 display operating at a customer site.

See picture... the needles should have gauges above them... the two buttons lower buttons on the right hand side should have graphics (menu and maintenance wrench).

It seems like the standard IQAN library graphics stopped working (gauge image, wrench image, menu image) while custom graphics that we have added ourselves are still working...

Software is IQAN 3.19.

Any one see this before?  Any ideas?

We will advise the customer to reflash software as I'm doubting there is anything else that can be done.  

Where possible we try to use the 'built in' error checking configurable directly on the input of the signal into a module (VIN, CIN etc). We find some functions particularly useful for example the error value that is set when a fault occurs. Some customers dont full understand what 'low error' or 'high error' means on a screen message particulary if they are not used to our machine control system. More often than not we resort to switching the built in error checking off and inserting our own messages that we can fully control whats written to make it easier to understand, time delays, multiple lines of text etc. Below is a screen shot of a standard IQAN input error:

Our customer needs more information about the error than is listed above, we normally like to have an error code number, multiple lines of text so they can have an idea of where to go with the fault, live value of the signal into the controller etc. We like the idea of setting an error value, this can be achieved using our own logic but takes time to put into the software. We also find that we normally have our own error logs, and we would rather have faults that are generated go into a dedicated log, different from the regular MD4 log which stores other items, could this be an option possibly? Same goes for outputs on a system. I guess we are looking for more configuration over whats displayed on the built in IQAN error messages.
