MD4 touch screen not responding

Jean-Marc Zanni 5 years ago in Master modules / MD4 updated by Kevin 2 weeks ago 5

We use the MD4-7 for all our systems.  I have one of my customer with a Fairly new(3 years) but rarely used unit for a test bench.  He complains and I witness that is touch screen is often not responding.  It is mounted on an aluminum test bench.  Sometimes if he moves the unit away from the bench it seems to respond better but not always.  We tried to ground the unit but it did not improve.  Do you think this is an hardware issue or is there mounting issue we need to look at?

ID-Tag 4-7 for Molex MX123

Fredrik Forsberg 5 years ago in Master modules / MC4x updated by Gustav Widén (System support) 5 years ago 1

Hello,

ID-tag 4 to 7 does not exist for Molex MX123.

We use 4,5 and 7 today and have to re crimp those ID-Tags for MX123.

When do you plan to offer ID-Tags 4 to 7 for MX123?

Regards

Fredrik Forsberg

MC4X CAN bus labelling different in manual and IQAN Design

Kevin 6 years ago in Master modules / MC4x updated by Ulrik Zakariasson (Software development) 6 years ago 1

IQAN Design refers to CAN bus on the MC4X as A, B, C etc, manual (under installation) refers to it as numbers 1, 2, 3 etc. Although its obvious to work out, its better for us if its one designation across the board to avoid confusion when cross referencing documents.

CAN connection between MD3 and MC31

Diogo Tasquin Reducino 6 years ago in Master modules / MD3 updated by Gustav Widén (System support) 6 years ago 5

Hey there!


I'm using a MD3 and a MC31 on my application. I'm transfering the application through an USB-to-CAN interface (KVASER - LEAF LIGHT). I'm using the same cable to transfer the application simultaneously to MD3 and MC31. The transfer completes greatly, I can even use the Measure feature on IQANDesign to get signals from them both. But, between them, the MD3 can't see the MC31 (No contact error), as well as MC31 can't see the MD3. Can anyone help me? I can send pictures of the connection and the error that is occurring.

MC41 losing CAN comms

Captain Sprocket 6 years ago in Master modules / MC4x updated by Gustav Widén (System support) 6 years ago 1

We are using a MD4-7 and x2 MC41's on some of our machines (we actually wanted to use only x1 MC42 for these jobs but we are still waiting for the parts to arrive and have deadlines to meet so we are just using what we have available to get the job done)


But last night we started testing the machine and went through all of the procedures and functionality when all of a sudden an error appeared on the display telling me that one of the MC41 controller lost comms, but the other one was still fine and giving readings... So the 1st thing we tried to resolve this was typically switching the machine off and on, but this time there was no CAN comms at all.


We went though the wiring harness and made sure that everything was correct and the wiring was all good, so we then went and replaced both these controllers with new MC41's we had in stock, we plugged it in uploaded the software and the system was happy again with the new controllers and it is still working fine at this moment... So I took the 2 faulty MC41's to my office and connected it all together to try and diagnose the issue. 


Each time I tried uploading software (using IQANDESIGN 5.01 via ethernet) it kept on warning me about the incomplete system and that only the MD4-7 will be updated.


Eventually we switched from CAN-A to CAN-B only on the MC41's. but upon each attempt to upload the software, the same "incomplete system" warning appeared. 


So I just left it for a while and a few minutes later decided to just try again uploading once more. Well it worked all of a sudden and that is also a big problem, because I didn't change anything where I could say " there, that was the problem".


This is worrying us a bit, because we have no idea why this happened in the first place and secondly these machines are going to the middle of Africa... So this sort of thing must not happen at all!


I have only been using MD4's and MD3's with XA2's in the past without any problems at all, these are our first machines using the MC4x family and this is also the 1st time that I encountered any issues like this on IQAN.


Have anyone else experienced this before?  I have no idea why it failed or why it started to work again and this is definitely not the correct answer to give the person asking this question when there are deadlines to meet.


The other thing to mention also is the LED's on the controllers which blinked bright yellow 3 times then blinked dimmed yellow 3 times while it was not communicating. which also does not correspond with these fault codes in the manual. There was no RED LED blinking at all.

MD4 10" screen

Richard 8 years ago in Master modules / MD4 0

Does anyone know how the 10" version of the MD4 is coming along. The last information I had was the unit was not released for production yet due to screen fogging issues. I hope that is resolved as I may well have an application for the unit.

Is the unit available for sale?

MD4 user inputs

Richard 9 years ago in Master modules / MD4 updated 7 years ago 2
I want to use multiple MD4 units on a new project but the problem is in our application the user may be wearing gloves so I am not sure a touch screen is useful. My first idea was to put a CAN open tactile button pad by the side of the MD4 unit but have come up with a blank.
I have tried - Grayhill - Graf-Syteco and powerkey so far who do have keypads but they do not have a size or shape currently in production that fits nicely alongside the MD4 (7").
Does anyone have any ideas?

usb Ethernet adapter for MD4

Zach 9 years ago in Master modules / MD4 updated by Mitch Houle 5 years ago 7
I have dealers and techs all over the world who connect with USB to the machines with the IQAN system.
Could I add a USB port and a USB to Ethernet adapter so they can continue connecting with USB?

Does anyone have a better workaround?
