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.

I have multiple MD4-7 low side output permanently latching off when it is driving a relay after a month or 2. Over the course of 2 years this seems to only be happening on the last few units I received, but not on any of the older ones. The current maximum on the output is 300ma and the relay I'm driving has a maximum inrush of 350ma for less than 1us, and it has a built in surge protection suppressor diode... I would normally say ugh I should have been more careful but I have quite a bit of units with all the same relays driving off of the same outputs without problems. has there been any component changes in the past couple months to these units? Anyone else have any thoughts on what might be happening? 

We have a system with MD4 connected by master bus to MC3. We have a XC23 connected to the MC3 via expansion on different bus to master.

On ignition switch on the system appears fine and all outputs and inputs into XC23 are OK, during engine start there appears to be a dip in voltage which causes the XC23 module to show 3 red, 1 amber LED flash (can error / timeout). When we get this error flash, IQAN run says system health is OK under the XC23 and MC3 modules and IQAN design shows the outputs on XC23 going true and false as expected. XC23 module outputs however are non functional, the module is in error state and refusing to operate outputs whilst the LED flash sequence above is active.

There are no logs in the MC3 for failed communication with XC23.

Are there any recommendations for how to resolve this? Is this normal behaviour for a dip in voltage on XC23? All other modules appear to be unaffected by voltage dip, its almost as if XC23 does not recover and outputs are non functional even though IQAN design thinks they are? Would pulsing 'enable' property just after engine start re-enable the module in event of this error flash?

Running IQAN Design 4.07 with machine voltage 24V dipping to around 10/12V on startup.

Hello

Want to drive a D1FB Parker proportional valve withMC2 controler... Would like to know difference between PWM and so called COUT output (also said current mode and closed loop) both have to drive 24v coil. It seems they are both Pwm? BTW cannot find recommanded valve dither frequency.

Thanks for your help

Hi there!

I've got a small problem and i had this before but it went away every time but i dont know how to fix my problem

if i start up my MD4-5 it shows our own startup screen (this is good) and then, after the startup, it shows an error message:

and it stays in this screen.

I've connected the Bat+ to 24V bat- to the ground and the RTC to the 24V with a 1.5K resistor.

is there any reason why this could happen?
