Summary of the application: The controller receives, with a certain frequency, CAN messages containing data from 5 or 6 sensors in the system. We are going to program Lookup tables in the controller using Simulink. Lookup tables will be used for processing input data. This processing generates informations to be sent to the central controller. When we say Lookup tables, we are talking about several tables of size which may be important. The size of these tables can reach hundreds of MB.

Questions :

In the case of simulation, we will not have memory problems because these tables will be in the Matlab workspace. However, in the real application:

• Will these tables be saved in the controller?
• Does the internal memory of an MC41 allow it?
• Does this not affect the computational time performance of the controller?
• Could you confirm the possibility of using an MC41 for this application?
• Could you confirm the possibility of using the Simulink lookup tables in an IQANdesign application?

In the training given to us by RGDH, we did not talk about the use of Matlab-Simulink in IQANdesign, and there are very few tutorials on the subject, Could you please provide us with documents or tutorial videos on the Matlab-Simulink-IQANdesign coupling?

The description for the GFOUT Transmit rate says it will accept constant and constant channels.  Type is integer unit ms.

I do believe constant Channel do not specifically exist.  Description for the integer parameter does refer to them as constant channel.

Yet the Transmit rate box does not seem to accept it.  What am I doing wrong?

Thanks

MC3 with parameters appears to have strange text characters when viewing in IQAN Run. System is running IQANDesign 3.19. Parameters remained correct when viewing them in IQAN Design before and after adjustment, just text and values appear like this in IQANRun.

Tried simulation but does not have this behavior. Any ideas?

Any code or hints on how to eliminate system oscillations from lifting a weight with a crane?

Would it be possible to make the input/Output calibration properties able to be pulled from existing channels? We currently have sensors whos inputs need to be recalibrated when changed out and we need to use memory channels or adjustable parameters to accomplish that. It would be nice to use the existing property values for this.

We are experiencing an issue with several of our MD4-5. The issue is with any button on the MD4 whether they are parker system buttons or programed virtual digital in. Intermittently, the buttons tend to freeze therefore acting like a toggle when they are not. Please see below some points that I've noted.

1. The program is updated to its latest version of 6.05.
2. The cycle time of the MD4 during operation is 30ms.
3. The cycle utilization of the MD4 during operation is 20%.
4. The memory utilization is good.
5. The MD4 is located inside and operating at ambient temperature.

If I send a new simple program to any of these MD4, the issue will go away. I did notice, when I disable a certain amount of function groups within the program, the issue goes away. Therefore, I think its pointing to a program issue, but it seems strange to me because as mentioned above everything looks pretty good. Note: This is a multi-master system where the MD4-5 is the master. Any thoughts?

We are getting Log Errors on one of our machines. We get the same IQAN message 11 times. 1 of the 4 master controllers in our system happens to have 11 logs in it. So I'm assuming that is the culprit. We tried to pull logs from it and it was empty.

Any more info on this message? 

We have this same code running on hundreds of units and this is the only one with this issue. Hardware related ?

I created a safe password for a Login using the new Safe password request file. He loaded the safe password on the other end and the password was added to the password manager, but it did not allow him to login. When he entered the username in the login box it did not populate the password.

I'm a new user of IQANdesign. I mainly work with versions 5 and 6. Is it true that I cannot use the FOR, CASE and WHILE statements in Qcode?

Thanks in advance for your response.
