We have a customer that is experiencing graphical errors with an MD4. S/N 1535280044. Customer is complaining that the display sometimes is black, sometimes white and sometimes multicoloured lines:

Does anyone know why this could be happening? It appears to be happening sometimes at startup, but also when machine is running (randomly dropping out). Im not sure if its the hardware issue that was changed a couple of years ago on the MD4?

I would like to define a common remote connectivity solution that works across MDL2 and MD4 machines. 

Will G3 work on both?

I can open up an MDL2 application file in IQAN Design 5.03,  add a G2/G3 modem, connect them both to a diagnostic bus and save the file.  

Will IQAN connect work properly ?

I have encountered a problem with DOUT on XA2 modules. We operate several Parker D1VW (NG6) valve, with multiple XA2 modules. Some DOUT (from different XA2) does not activate the magnet coil, although it looks completely correct when I'm connected to IQAN Design . DOUT = Tru.

We use valve contacts with zener diodes, it works on most DOUT otherwise. I had to change the output to PWM instead and then it works without a problem. Is there any problem with the XA2 modules, or are the Zener diodes that do not work against XA2?

Due to a voltage drop in the system, because of an electric fan switching on, all the voltage inputs give a low error.

The strange thing is that the voltage drop is not so big. it drops from 27 to 22 for only a sec due to the high start current of the fan.

Is this normal, I thought the modules could be used in 12 VDC system also. So the voltage drop should not be a problem.

I was told some months ago, the the MD3 would be obsoleted sooner rather than later, but I have not seen anything further on this.

Any idea how far out is the timeline on obsoleting the MD3?

I am using an IFM Efector 4-20mA 2 wire sensor on the MC41 inputs capable of sensing current.  Their hookup diagram is what I expected connecting one side of the sensor to high and one side to the sensor port.  The input shows a high error when I'm in a neutral state and I can confirm with an ammeter in line that I am sending 4mA to the controller.  My best guess is there is too much impedance and internally it is not correcting for it so I tried adding a 5k resistor to ground externally to split the current.  It now senses 3.8mA but is no longer accurate over the range.  

When the G11 Bluetooth Modem was still in BETA one major limitation was that you could not flash a password protected project.  

Has the limitation been resolved?

Hello admins  & all,

I bounced into this forum while searching for information pertaining to IQAN-DG instrument.

My problem is that the display is distorted or rather damaged. On the printed circuit board, it stateds DMF5001NY-LY  Org_DMF5001NY-LY.jpg . I managed to acquired a new display unit DMF5001NY-LY-ATE-BBN . After installing, this display unit seems not compatible! The resolution of the text seems

weird, enlarged, cut-off and shifted to the right side Text_res1.jpg Text_res2.jpg.

As i am lack of technical information regarding the screen resolution, i am lost here. I assume this is a resolution problem with the new display unit.

Any information, help or solution to this problem is greatly appreciated.

Regards

David

Any information on this? I just saw it in the release notes for 5.03.11.5029, I added it to my project but I can't figure out how to do anything with it right now.. but information on the hardware would be nice.

We have an application which uses MC43FS module. We get an error code showing 4 x red, 2 x amber, 1 x amber, 1 x amber, 4 x amber. I have isolated the fault to one wire which is causing this error code, C1:10. The manual shows this as VIN / DIN, but we have found when connecting 24V to this pin once the module is booted, all is fine, no error code is generated. If we connect 24V to this pin and power the module on we get the error code flash up, the module shuts down, no communication is possible.

I have used a different MC43 to test and same error is generated. I have also tested by only connecting power, address tag and C1:10 and I still get the same error with the scenarios listed above. Is this a fault or is there something we are doing wrong (perhaps the allocation of pins)? Its almost as if the pin should only be a VIN and only accept 5VDC max, or perhaps its a pull up instead of pull down, is this what the error code is stating? We are unable to tell what the detailed error code is, only 'stopped critical' is listed. I will send across the video file of the error flash.
