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!

We have an MC41 connected to a PLC via the CANbus.  We push 16 RPDO blocks from the PLC to the MC41. We are on our 10th unit and suddenly on unit #10 we are not getting any values from RPDO 11, and it is greyed out when we look at it with IQANdesign.  Help?

Hello,

I am currently working on a machine that uses an IQAN system with an MD4. For some context: it’s a mobile hydraulic machine driven by a diesel engine. I’m running into an issue that I haven’t been able to pinpoint to a specific cause, and I’m wondering if anyone recognizes this error code or has ideas on what I could try next.

The error code I get is:

Run fault PID 90131 TID 14 Signal 11 Code 0

The situation is as follows. When I start the machine, everything initializes fine. The whole IQAN system comes up normally, the UI works, and I can operate the control system without any issues. When I give the signal to start the engine, it works in two steps:

First, the engine ECU is powered up. Then the ECU sends an OK signal back, after which I need to trigger the start again to actually crank the engine.

The ECU and the IQAN system communicate over CAN. However, as soon as I give the first start signal and the ECU powers up, the MD4 immediately goes into a blue screen and completely locks up. Nothing responds anymore, and I can’t recover from the error without completely disconnecting the system and doing a full reset.

As far as I can see, there’s nothing useful written in the logs that I can trace back to the blue screen—only the information shown on the display itself.

I’ve been trying to diagnose this for a while now, but I’m not sure what could be causing the fault in the first place. The only thing I could find online was a post mentioning CAN bus overload, but I don’t really see how that would apply here.

At this point I’m mainly looking for ideas on what could cause this error, or where I should start with further diagnosis. Any ideas are welcome.

Hi,

We are converting a machine that had MC2's, XA2's, XS2's & MC3's to use MC43's or XC43's. There were not enough DOUT's when the application was originally written, so COUT's were used and driven from either 0% to 100%, or from 100% to 0%.  There is no proportional control used.  The command input to the COUT is either 0% or 100% can instantaneously switch  from either OFF to ON, or ON to OFF at a 10 mS system cycle time. See below for an example of the code. Are TVS, or Diodes, required across the COUT to protect the outputs from instantaneous changes??   

I am trying to change the speed on the diagnostic bus between an MD5-8 screen and a G12, but it only works at speeds of 250 or 500 kbps. 

At speeds of 500/2000 kbps, I get the error message ‘No contact G1x’.

According to the G12 instructions, it should be able to support this speed.
