Hello,

I am having some trouble with the Parker MC41. I have a display button on another MD4 that enables / disabled the output on Pin 45 (DOUT-HS). I am seeing a proper system voltage of 12.26V when the value is true, however when I set it to false Pin 45 goes to 11.68V. Is this normal behavior? Should I have some sort of diode in there to get the desired on/off I am expecting?

Thank you.

The MC43FS manual states that:

Note that for the MC4xFS, a voltage input combined with a current loop input is not
sufficiently diverse if the two signals are following each, the higher gain error has to be
considered.

Does this mean a single sensor measuring voltage (single output from the sensor) into a VIN and also current from the ground of the single sensor into a CIN? Is this what is defined as combined? ie. singe sensor, 2 inputs.

We are planning on using a single voltage output sensor providing a single VIN, and a separate sensor with 4-20mA signal output into a dedicated single CIN. Notes in the manual suggests we cannot do this because they are not crossed, even though they are independent sensors, different technologies and have separate wiring. What's the restriction and why, is it because it uses the same AD converters in the module? The pins are not shared (cannot be configured as voltage inputs or current inputs) so unsure of the reasons behind this.

Just looking for clarification really as the statement seems to suggest we may be able to if....'the higher gain error has to be
considered'? Both the sensors we are planning on using are not crossed (signal outputs increase as pressure rises, one voltage the other current).

Thanks!

Hello,

We are using a MD4-10 (IQAN-6) as main controller for our vehicle. Recently, a bluescreen appeared while we were disconnected from the vehicle via the controller's ethernet port connexion; we were measuring. When it disconnected, I also felt a small static shot from my laptop (I don't know if this is related to the error but it is something I have noticed when it happened). The error code is os_error(0x1000002) with run fault pid 90131. I have looked on IQANForum and I have seen this error before but not from the same source.

We are fixing the wire ethernet connector on the vehicle but is this something that has a precedent ?

Have you seen this type of error before?

Thanks for the support.

Best,

I am using a MD4-7 on my test bench for one month approximately.  It seems to be corrupted.  I can no longer send projects via ethernet or PCAN from IQANdesign 5 or 6.  I have also tried a coworkers laptop and failed.  When I send a project, the display momentarily blue-screens then restarts the existing application.  IQANdesign eventually reports "No Reply."

The only way I have been able to send a new application is in safe-mode by removing the ID tag resistor.

Are there any other recovery steps I can attempt before sending this display back to Parker?

Hi, 

I have an old machine using the MDL2 master module and on start up it is showing blue screen error:

Proc: OSP sys MainProcess

Code: 3.17.2-BUS2-800631BA 

Is there any way to salvage this (delete logs?), or has this unit served its time and is on its way out?

Thank you.

Good Morning,

I have completed my first project in IQAN Design and while looking at the project documentation, I noticed what would seem to me like an error. Please see the attached screenshots on how the one pin list  shows pin C1:4 under the Master Module as being ADDR-L and under the Gateway module it shows C1:4 as being CAN-H. What am I missing?

I have an application that uses 2 x LC6 joysticks for driving a safety circuit. Primary signals are fed into MC41FS and secondary comparison channel into XC21. I used XC21 as there are not enough VIN into MC41 - 8 x 2 = 16VIN (we have space restrictions preventing bigger or multiple MC4 module).

Modules share the same power supply and are located next to each other, but power supply to joystick (VREF+ & -ve) comes from MC41 module. Secondary comparison VIN into XC21 has no VREF-ve. To prevent fluctuations on VIN on XC21 do I link VREF- between MC41 and XC21?

Hello, I have a current leakage problem in the XC-43 and XC-44 modules.

I am using Digital Out HS outputs to drive LED blinkers, but they don't turn off completely, there is a 5.8V voltage leakage. The flywheel diode is installed but we have had to install some power resistors in parallel to get them to switch off completely. The same problem has appeared when connecting a buzzer to Digital Out HS.

We powered up 5 new systems, all identical programming and 2 of the displays show this error. 

We aren'y connected to the VREF A. We're trying to get some factory support but haven't been able to get any response on this.
