IQAN-MC4x family ready for production

Johan Lidén (Product manager) 4 years ago in Master modules / MC4x updated by TKM 3 months ago 2


Our latest generation of controllers are finally ready for production. The IQAN-MC4x family is the fastest and most capable controller range we have ever done. It comes in three sizes to support any application size, from the entry level task oriented control up to the high I/O configuration for complete machine control.

First out from the production line and available now for deliveries is the performance optimized version of IQAN-MC43. The IQAN-MC41 and IQAN-MC42 will start shipping next month (December 2016).

Work is ongoing with the Functional Safety versions and units capable for implementation of SIL2/PLd safety functions is planned for production Q3 2017.

IQAN-MC4xFS SIL2/PLd controller series released

Gustav Widén (System support) 3 years ago in Master modules / MC4x updated 3 years ago 1

On December 15th, we released the IQAN-MC4xFS series, with safety certification by RISE. 


The release means that we now have SIL2/PLd versions on all three sized of the MC4x series:


  • IQAN-MC43FS
  • IQAN-MC42FS
  • IQAN-MC41FS

You can read more about the new product in the press release.


In the press release, we make a reference to the EN 13849-1:2015 update. The EN 13849-1 standard lets machine designers create safety functions either based on electronic components certified by the manufacturer (like the MC4xFS), or design safety functions based on the EN 13849-1 architectures. 


With the original 2006 release of the EN 13849-1 standard, there was great emphasis on on calculating hardware reliability, but requirements on safety related embedded software was not as clear as in IEC 61508. Now with the new 2015 update there is a clear limit, implementation of PLr=a and PLr=b functions are accepted on standard controllers, for PLr=c and higher, the use of controllers with safety certification is necessary. 


To learn more about this topic and how to design complete safety functions in accordance with EN 13849-1, you can sing up for the IQAN focused training on functional safety

IQAN- MC4x real time clock not available for logs

C. Harp 3 years ago in Master modules / MC4x updated by Eric Metz 3 years ago 2

I recently discovered that the MC4x family does not have a RTC pin and therefore when you go to pull a log on a file, it simply gives you a "start number" and a base line of 12:00:00AM. This is not sufficient for what most of my customers needs are. 

Are there any plans to add in an RTC pin to enable us to have actual time available when logging.

MC43FS - Are there any plans to upgrade RAM/Flash on this module ?

Nick Pridham 1 year ago in Master modules / MC4x updated by Gustav Widén (System support) 1 year ago 5

This module supports alot of IO and 5 x CAN. Very simple functions to serve all of the IO and CAN easily burn the available resources and I am wondering if there are any upgrade plans ?

ID-Tag 4-7 for Molex MX123

Fredrik Forsberg 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 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 Arscott 3 years ago in Master modules / MC4x updated by Ulrik Zakariasson (Software development) 3 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.

MC41 losing CAN comms

Captain Sprocket 3 years ago in Master modules / MC4x updated by Gustav Widén (System support) 3 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.

cmartin 3 months ago in Master modules / MC4x updated by Wilfried 3 months ago 3

How is the performance proportional pressure control devices, such as a Parker RE06 without on board electronics, using Parker MC4* current output channel? The Parker industrial driver, PCD, uses a 10kHz PWM frequency to drive an RE06 coil. The Parker MC4* has a current output PWM frequency limit of 500 Hz. I have driven an RE06 coil using Iqan products in the past without noticeable performance issues, but wanted to see if others have done the same.


Thanks

IQAN M43 Error Code: Manual says contact Parker

Barnhart Crane 5 months ago in Master modules / MC4x updated 5 months ago 4

4 red flashes, followed by a yellow flash sequence of 2-2-1-3

This continues to happen when trying to start the engine of the machine. As if maybe the battery voltage is going too low momentarily.


Once in this state, the IQAN module cannot be communicated with using IQANRun 5 and is not operational until powered off then on, but will deliver the above flash sequence. 

Any help would be appreciated.

Answer

Please the footnote related to a 4:2 blink code in appendix B of the instruction book.  This is likely a fault caused by extreme voltage caused by cranking.

Coil Suppression on MC4x Outputs

Seneca 5 months ago in Master modules / MC4x updated by Gustav Widén (System support) 5 months ago 1

Hardware Question:

In the Documentation for the MC4x family of controllers - it says in many places to use diodes for external coil suppression, for example when driving a relay with the Digital Out HS driver from the MC4x.

A relay that I have specific to my application requires (highly recommends) the use of varistor coil suppression, which is less "harsh" on the relay device during transients. The specification requests a clamping voltage of 3x the coil voltage, i.e. 36Vdc for a 12Vdc relay coil.

Are there any adverse affects of using a varistor instead of a diode for coil suppression? 

Perhaps this could be also compatible with the hardware design of the MC4x series of controllers?

(Hint: I already have tested this configuration on my system to many thousands of cycles under load with no discernible affect on system operation or relay operation)
