Hi,

to start I wish to say that the development with external functions and solution library is a really nice addition to IQAN.

Now to my request. Lets say you have an external function called Function.

The Function has input x an output y.

Whe you create 2 new instances of the external function you can rename each function. That is good. The names of the input and outputs cannot be renamed. That is the way it should be.

However, here comes the problem. In the example I have Variable as a math channel. I cannot  read any of the outputs from either Function A or B simply because now there are two channels in the system with same name y.
If I delete Function B, it is possible to assign the Variable math to y.
   And this is actually a problem in the display pages as well. If you use the same channel name then it is impossible to know which channel you are choosing properties and values for objects in display pages.
My suggestion is to use same syntax as any of the object oriented languages.  Example in QCode:  result := Function A.y
And similar when selecting in the display pages menus.

I typically set the scope of a channel to public if they're used in 2 or more additional function groups, and function group output if the channel is used in only 1 other function group.

But I decided this somewhat arbitrarily. What are the ramifications of using public vs FGO? Does public scope cause things to run slower? Are there some good rules of thumb?

Hello All!

I've been giving a try IQAN 5, and it's new graphical features, because I wanted to make some dinamic drawings to represent the position of an elevator crane.

I Found it easier to use images (X,Y,Angle) instead of lines (X1,Y1,X2,Y2), for this purpose. And, obviously, with images I can get a closer representation of the actual machine.

But...smooth animations totally runined my plans. 

When X and Y properties get a new value (from a variable), the image will move instantly. 

But, when its angle property changes, the rotation of the image won't change instantly, it will turn "smoothly". Similar to the smoothed movement of gauges or bars... which I don't really like much either, by the way.

Please, watch this example:

Is there a way to disable animations?

Perhaps a checkbox or smooth factor (in images, gauges and bar properties..) in future releases...?

Thanks a lot!

Is there a way to get (2) Low Side Outputs on an MC42, without needing to use the High Side pair?

I need to send 2 AL outputs to another controller to control certain functions.   So I don't have anything to connect the High Side to and not get a critical error. 

In the Instructions it looks like you should be able to as Dout_E thur O are all low side, but you cant not select that in IQAN.  ( I know they share the CAM output)  But it would be really nice to just have the LS for low current logic control like I am trying to do and not need to setup to the MC43 to just get that. 

On a different note, it would be nice if you guys could add the type of input/output they are. 

High Side or Low Side so it easy to select the one you need. 

Dear

I will be greate to :

- add an option on the round math function, by default it is half. But if you need the whole part you cannot. Exemple 5,4 -> 5, 5,8->5 (it is the int() function). (type of rounding : https://en.wikipedia.org/wiki/Rounding)

- add latchtime fonction. instead to use an separate IDC with delay On and Off, an function like this latchtime(input chanel, delay on, delay off), can be greate to simplify the code.

- add hysteresis function, hysteresis(input chanel, switch on if sup, switch off if under).

Hi forum users,

I have a project. I want to make connection like this.

Is there any problem ( connection interrupt , data loss etc.)  if I make the connection as in the picture?

Should I change the communication speed?

m=meter.

Thank you for your help.

Regards. :)

Is there a way to adjust SPN 3350 of the TSC1 control in IQAN or will I need to build my CAN message manually to accomplish this?  It looks like it defaults to 31 and I need it to be 2.

When an application is loaded/started with a MD4 as master, and the display language is Japanese. After start up the display remains black for 10 seconds. Then the start display appears. When english is the choosen language, there is no time between start up the application and showing the display page. For a user it is as the display of the MD4 is broken when showing the display page is taken so long.

Hello,

I recently came across an "Invalid Reference" error in a FSM channel. I reviewed the contents of the states and the transitions between them and I didn't find anything that stands out as abnormal. This is the first time I have come accross an Invalid Reference error and I cannot identify the source. Could you please advise?

Thanking you,

Best Regards,

Nico
