MD4 blue screens

Adolfo 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 7

Hello,

We have a machine working from october 2020. it has a MD4-7:

On 7th June, the customer sent us this blue screen:

After switching off and on it has started perfectly. this is the MD4 log where we cannot see anything strange:

Shredder display master log (PY200046 - AC....irlx

Last week we received another feedback from another customer (working from may 2019) with this blue screen:

By the moment, it has appeared just once. We hope this will not appear again.

But, if it possible, we would like to have any clue about waht can be the reason of those blue screens? We need to say somthing to our customers...

Thanks in advance,

Adolfo

Change of a Transmission rate of a GFOUT

Andy Pauly 2 years ago in IQANdesign updated by Michael Carlyle 2 years ago 1

Hello

I have an application where the Transmission rate of a GFOUT must change during operation. 

The Rate should be 1000ms. But when the cylinder moves the rate should drop to 20ms. I cannot use therefore an Initializion block. How do i get it to work.??

Regards

Saving values and exporting them into .csv

Chris D 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 5

Hello everybody,

right now I'm working on a project wich requieres saving a lot of values and saving them in a .cws file.

I want to monitore around 10 different channels over a time span of around 8 hours on a frequence of around 100hz (= 100 values per channel per second). 

Additional i want to add a timestamp to each value. This needs to be kind of automated. In the best case i would want to push a Button on the display at t=0 and after around 8 hours later,i would push another button to stop the measurement, connect to the MD4 via Laptop, download my values and save them in a .cws file. 

I thought of something like a Measure group wich can be startet via the push of a button and wich saves the stored values and lets me export them.

I'm really gratefull for any help with this topic.

Thank you very much.

Example:


Timestamp [ms]Value1 [%]Value 2 [%]
100,210
200,512
301,222

Disabling duplicate address tag modules

Jesse j Kilde 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 1

We tested this in the shop before combining programs with duplicate address tags. see the images below. there are never two of any address in the program being looked for at one time. this worked good for a half a day during testing and now we are seeing issues with the duplicate addresses loosing contact but not giving a duplicate error as you would see with two of one addressed module. the machine will work for a while and then loose contact for a few seconds and come back on line. Is this a program issue because of duplicate addresses or something else i am missing?

Not a bug

J1939 parameter out is limited to 7 characters

Codie 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 1

I am trying to input a fixed value to a j1939 parameter with 4 bytes but after it accepts the value it moves the decimal and removes the last couple integers. My resulting outgoing message is wrong. I tried to input 1955772161 to receive a message of 01 b7 92 74. but instead I received 00 b7 92 74. I am using iqan  6.06. I can use two 2 byte j1939 outs but would be nice to fix this.

Opening 4.07 file in 6.06

Michael Carlyle 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 2

When trying to update a older 4.07 program by opening it in 6.06 - I get an error Corrupt file.  I can open it in IqanDesign 6.04 and save it and then it will open in 6.06 so I can keep going but there seems to be a bug in 6.06.

IQAN6 project to IQAN5

Ville Laine 2 years ago in IQANdesign updated by anonymous 2 years ago 6

Ok now it happened.

I have a IQAN5 project that includes MD3 and accidentialy opened it with IQAN6.

Frustrated that I need to have multiple different versions installed.

Is there any way how I can convert IQAN6 back to IQAN5.

Or please add MD3 legacy support to IQAN6 like XA2.

example solution for a single 2 axis Joystick used to control dual tracks on a machine like a dozer

Andy 2 years ago in IQANdesign updated by Ryan Bland 747 1 year ago 7

Hi People

I'm relatively new to IQAN but have been programming industrial PLC's for years. A few years back I used a dual axis 0.5 - 4.5v DC joystick and an IDEC PLC to create, among other solutions on the machine a drive motor tracking system for a large machine that is about the size of a D9 dozer that used a single joystick to control fwd-rev and turning. I may not be looking that well but I cant see any example of a single 2 axis joystick that is used to control a tracking system, rather all the examples provided with the software seem to have a separate input controller for each side (like an excavator) which is pretty simple to achieve, unlike the more complex (I think) math required to handle the 2 axis to 2 separate pump dual direction control.

Can anyone point me at an example I can use for this use case?

On this same machine I used a pair of modbus over RS485 ultrasonic height measuring transducers to control the machines working head height. Does anyone know of a set of ultrasonic height transducers that can run natively over canbus, or a modbus to canbus converter that I can use to deal with that function from the IDEC solution using IQAN?

The solution I have in place has heaps of individual inputs and outputs and hence the wiring on the machine is complex and of a single hub and spoke style rather that the more distributed multiple hub and spoke that a multi controller iqan solution would provide. Ideally I would like to look at moving from the IDEC PLC solution (Not that there is any issue with the IDEC controller, just the whole machine wiring complexity)

Thanks for any guidance you can provide

Regards

Live measure of look-up tables

NEricson 2 years ago in IQANdesign 0

Would be nice to be able to view live, for tuning reasons, what block of the lookup table is being calculated. Not sure if its possible but it would be handy in a program of mine.
