Array problem

Tuomas 7 years ago in IQANdesign • updated by Pierre Fagrell 3 years ago • 7

Example: I have array what size is 100 and If I have only 60 measurements there, How I get minimum and average values from these measurements?

ArrayIndexOfMin and ArrayAverage calculates all array 100 values even these empty 40 records and then I get wrong calculations.

How do I get minimum and average values only from records what contains measurements bigger than 0?

Input from video feed

Martin Gagne 7 years ago in IQANdesign • 0
It would be really great to be able to take the video feed from an Axis camera as an input into the MD4 to be able to do image processing, for example, to be able to check for high intensities of light and relay specific messages over CAN communication.

IQAN 2.6 switching pages automatically

Zach 7 years ago in IQANdesign • updated by Gustav Widén (System support) 7 years ago • 3
I tried to save space in a program by deleting a display page function group that ran the pages from a state channel and virtual inputs.
Then I put the page selection onto the buttons in the display pages of an md3 running 2.6

So now when I press the down arrow key, the next page displays.
How do I set a trigger for a specific page to appear?

J1939 Address Claim / Start Address

Metalfor 7 years ago in IQANdesign • updated by Gustav Widén (System support) 2 years ago • 9
Hello, I'm working with a J1939 project in which I want to use a MD4-7 as an instrument cluster. The Cluster must have the chance to make address claim in J1939 with the 23 address. Is that possible? Regards. Diego.

New property on the J1939 bus for address claim introduced in IQANdesign 5.02. Forces IQAN master modules to claim their J1939 address before starting other J1939 communication.

jframe input polling question

Zach 7 years ago in IQANdesign • updated by Gustav Widén (System support) 7 years ago • 1
On some machines I have a polling request set for every 500ms.
I wondered how often polling happens by default if I don't use the polling request.

Sometimes I have polling for engine hours, battery voltage, and fuel used.
Sometimes I don't.
I would like to know what to consider for determining when I should.
J1939 is configured for 250kbs.
I have 2 second timeouts.
I thought that the protocol went through each pgn to see if there was information to be exchanged, then it got the information from each pgn.
So if my timeout is 2 seconds, then I would think polling every 500ms would not be something worth doing.

It would be nice to be able to go online with the PLC and make changes. Our system is getting pretty robust in design and it would be a great troubleshooting tool. It also would be in line with what some other automation companies are doing, such as Rockwell and Siemens.
