Hi, I have a MD4 display and it does not recognize the ID tag anymore. Already did a update to the last firmware but without results. Any suggestions?

Are there details yet for a North American phase-out plan for MD4?

This thread lays out MD4 phase-out for Europe, Middle East, and Africa: https://forum.iqan.se/communities/5/topics/4483-md4-phase-out-notice

I'm having an issue on a MD4 where I have turned the terminate CAN off on all 4 busses but they still turn on the internal resistors. I end up with 40 ohms as I have 2 physical termination resistors already. If I power cycle the MD4 the resistance will be 40 ohms for a min or two and then it drops to 60 as it should be. then I power cycle the Md4 and resistance goes to 40 again and then drops after a min or two. Its seems like the MD4 will not take the changes but it has been set this way for several months and it has been reprogrammed dozens of times

I received a notice from my supplier regarding the MD4-7 phase-out, and they’re asking me to estimate demand through 2029, which makes sense and is good to get ahead of.

The notice itself lays out the following milestones:

• April 15, 2026: Parker requests estimated demand forecasts. Priority given to customers who provide information.
• October 15, 2026: Customer final orders must be placed prior to this date.
• October 31, 2029: Last date for shipments from Parker.

However, my supplier is insisting that I must place a firm purchase order by April 15, 2026 to cover my forecasted needs, not just provide estimates.

This feels earlier and more binding than what the notice seems to require.

Is anyone else being told they need to place firm POs this far in advance, or does this sound like my supplier might be trying to lock in business ahead of the actual deadline?

Hello everyone,

I'm new to the IQAN ecosystem but I want to start using it.

My first project will be a scissors lift platform mounted on a vehicle on top of a mobile workshop.

Since this platform require EN280 safety compliance, I plan to use MC43FS and XC43 units together with MD5-5 display and G12 module.

All safety relevant sensors and controls need to be redundant.

I need to understand which type of sensors to use with respect to the ease of implementation vs. performance.

Most of the sensors are now CANopen devices, with a lot of advantages (safety, resolution/precision, ease of hardware connection...) but not easy to implement in IQAN Design (at least for me now). (but I have PCAN + PCAN Explorer6, CAN analyser from GEMAC, CANTouch)

On the other hand, voltage output sensors are easy to implement in IQAN. (0.5-4.5V ratiometric, redundant or two separate sensors)

Most systems use 4-20mA sensors but the IQAN modules don't have so many inputs ( 2 or 4 ).

In my design, the cable length between the IQAN module and a sensor will be maximum 6m.

Which sensors type to choose? (always redundant sensor, or two sensors with two signals for safety relevant signals)

a. voltage sensors - more influenced by external interference.

b. 4-20mA sensors with 250ohm(0.1%) pull down resistors ???

c. CAN J1939, easyer to implemet than CANopen.?

d. CANopen, dificult to implement.

Hello I am looking at using the COUT channel to loop through a HVIL. I need to have open circuit and shorted to ground monitoring for that circuit so the COUT makes sense for that as it will fault either way and then I can generate a shutdown. My question is should I add a resistor to the circuit and if so do you have a suggested value or will it be ok to just loop HS directly to the LS? I have tested and I don't have any faults. I have set the Max Current to 30 Ma and Min to 5 Ma. then I set the Input to 50%

Good morning or evening, i have a question regarding the LS and also the HS outputs.

I want to control the blinking of some LEDs using the HS or the LS outputs (MC4X/XC4X), seeing the internal schematics from the instruction book, it seems the outputs are MOSFET outputs, just to be on the safe side, i want to make sure if they can handle switching frequencies (ON/OFF) of 8Hz (every 125ms). According to the help manual from the IqanDesign these outputs are supposed to be used for lamps among other things.

If they can, just for curiosity, what is the maximum frequency of switching they would be able to support, do they depend on the cycle time?. 

Thanks in advance!.

Hi,

We have in a electric cabinet one MC43[0] with a MD5[2], then we have a wired console 30m away with other MD5[1] together with 2 LC5 joysticks.

The problem is on MD5[1], we make 3 diferrent connection to check:

1) We first connected the LC5[0]+LC5[1] on its CAN B port as usual in previus system with MD4 we made. But Randomly we gets:

So we double check all the harware and wiring with no problem found. At this point was coneected 0T and 1T on each LC5

2) Then we connect one LC5[0] on the CAN B port, and the other in the LC5[1] CAN C port. Then we gets:

So the problem now is just on LC5[1], but with Multiple Addres Error even being alone in the CAN C port. At this point we added a 120ohm resistor on the MD5[1] to match LC5 termination resistors.

3) Then our last seting was LC5[0] on the CAN B port, and change the address to the other LC5[0] on CAN C port, so we gets:

But in each port, there is only one LC5, so is not posible to have a Multiple Address Error. 

The only way to make this work again is reset the whole system. This problem is happen in 4 diferent machines, all with MD5. Other machines with MD4 don´t have any problem.

Hi everyone,

I am looking for the original manual/instruction book for the first-generation IQAN-MG module.

I have managed to find the documentation for the IQAN-XP expansion module (Publ. no. HY17-8329/UK) on Parker's servers, but the manual for the IQAN-MG (Document no. 158221) seems to be missing or no longer available for public download.

Does anyone have a PDF copy they could share? I am specifically looking for:

• The full connector pinout (42-pin connector).
• The LED status/error codes for troubleshooting.

I'm working on a legacy system and any help in locating this document would be greatly appreciated.

Thanks in advance!
