Would like to use the HS+LS configuration to control the HV contactors in an Hybrid configuration.  I am reading note about using Diode to protect against EMF.  But I cannot find specification on acceptable EMF level?  Our contactors have built-in EMF clamping diode rated at 150V?
Also how does the open circuit detection in an off state works?  injecting a current i am assuming. How much?  Just want to avoid issue with Dropoff voltage for the coil.  

Hi There, 

Hope all is well,

Is there any possibility to drive Proportional 24v 33Hz Pulsar valves with the PWM outputs from a MC43 ? Reading the manual it states that this will not work from MC43,but reaching out to see if it is possible.

ATM I am using the proportional flow from the pump and making the Pulsar more like an ON/OFF, This is working currently but would like to use the Pulsar proportionally. 

Thank you 

What's the realistic max bus length of master and diagnostics? I have an application that requires 2 masters at approx 100m apart from one another. Can these have master and diagnostic bus at this length?

I recall seeing in the IQAN instruction manual 40m is the recommended but maximum is 100m. Is this length take into account the 40 twists per meter, as 40 twists per meter at 100m length between modules would mean cabling of in excess of 100m actual cable length? If IQAN bus works at 250kbs, does this follow standard bus protocols and have a theoretical max of 250m @ 250kbs?

Will the soon to be added HS busses help any limitation?

I can always add an additional node to act as a midpoint transferring the data from one bus to another, effectively reducing the max length of a master bus to 50m, however it would need a diagnostics bus shared between all the master modules, which would be the maximum distance of 100m, and therefore the limitation?

Would CAN routing help me here with a central node that just runs its own independent program and routes the diagnostic bus and master bus through, and therefore has its own application file separate from the main 2 node application file?

What is the suggested solution for driving NG6 valves with standard 30W solenoids at 12V system voltage with MC4x/XC4x modules? 

We use the HS+LS digital outputs for driving Parker D1VW valves with "K" code solenoids in a 12V system. As stated in the instrucion book, max load per output is 2.5A, but the measured current is 2.7A (as in the D1VW catalogue). The measured solenoid resistance is 5 Ohm, but it should be within 7-14 Ohm (MC4x/XC4x instrucion book). 

30W solenoids are standard at other valve suppliers too, so changing the valve isn't an option. Change the system voltage to 24V also isn't possible for this project.

We are providing some sensors with a 0V supply through the VREF circuit on XC43 module but cannot find the maximum current capacity of these pins. The manual states VREF has a limit of 150mA, but is this limitation on both the +ve side and -ve side?

I was under the impression -VREF is connected internally to the -BATT terminals, therefore does this mean there is a higher current limit? I cant find a value in the manual:

we have strange behavior which XC43 Has constant high output as soon as get powered on , 

we have replaced 3 modules but the same situation was income .

temporarily that output sealed and waiting for your advise .

Hi,

I'm currently shopping for a USB-CAN adapter.

Looking at this thread : https://forum.iqan.se/knowledge-bases/2/articles/231-usb-to-can-interfaces , I went to Ixxat website because I used it in the past with IQAN system and it was working really fine. 

I know I could go with the regular "USB-to-CAN V2 compact" (https://www.hms-networks.com/p/1-01-0281-11001-ixxat-usb-to-can-v2-compact), but I came across the "simplyCAN" which is around half the price : 
https://www.hms-networks.com/p/1-01-0001-12001-ixxat-simplycan

Does anybody tried the Ixxat simplyCAN and confirmed it works OK with a IQAN system?

Have a good day!

Sam

Hello,

got a constant red LED on the status light from a MC2 and "no contact" and IQAN MD3 screen

that constant light is not explain in the book, i would guess an internal crash, could you confirm?

Is MC2 module replacable by MC2-M14 ? any software update needed ?

Thanks in advance

Hi,

I have an MC41 module and I want to pick up the signal from a speed sensor M18-4VPFF200-Q8.

Thus I calculated my Max Frequency (Hz) = (Max RPM×Pulses per Revolution)/60 = (200*1)/60 = 3.33 ~ 3 Hz

Do you have any input on whether the issue might be software or hardware related?

Thanks!

We have a requirement to have multiple XC43 modules remotely to the master MC43FS module. Its likely they will all be powered from separate power supplies and they wont supply the same 0V for batt -ve.

Is this likely to be a problem in terms of interference etc?
