F3+F4+Up buttons problem in MD3.
I am using IQAN design V3.19.7.4013. When I pressed F3+F4+Up buttons in MD3 same time, openning the main menu page. But I don't want this. This is a problem for me. What can I do for this.
You can see this problem the following video.
Ethernet Communication Port
With the new MC42 and MC43 master modules, I see you have the ability to communicate via Ethernet communication port. Where can I find this part? 
MC41 as slave
Hi
It will be possible use MC41 IQAN module as a slave?
How use MC41 and Panel MD3 together in same project?
Reservdelar till IQAN-DG
Går det att få tag på reservdelar till IQAN-DG displaymodulen?
Jag har två problem med min, displayen har till 1/4 blivit svart (sprucken) och programeringsknappen tar mycket dåligt (brända kontaktytor)
20mV jumps on VIN from XC23
We have an application for some voltage signals to be connected to the MC3 application. We have selected an XC23 module which compares a VIN signal on the MC3 with a VIN on the XC23. We have two of these functions (1 x MC3 VIN and 1 x XC23 VIN = one of two comparison functions in the application) measuring two different positions using sensors.
We have found that one set (an MC3 and XC23 VIN comparison) seem to follow almost exactly, however the other pair, the XC23 signal appears to increase and decrease in approx. 20mV steps. We are using VIN E and F on the XC23 and it appears the VIN F is causing the stepped signal even though it looks like it should have an accuracy of 1.22mV.
We have changed the sensor and XC23 module, but still appears to be doing it. Is there any reason for this behaviour? I have checked the VREF in the application, and all the VINs are configured to the correct reference voltage.
IQAN 4.05, application cycle of 50ms.
PWM as control signal
We want to use Spal brush-less fans, these fans have integrated electronics that control the fan speed. the speed can be controlled by a PWM signal mr 0 to 100% frequency 50 to 200Hz.
Is it possible to use the PWM output of the Iqan system to control this?

MC3 Current Consumption (and any other module)
Does the current consumption of the module (170mA @ 24V) increase if we start connecting sensors on the VREF pins or does this value include the max draw on both the VREF (140mA x 2)?
Does this apply to all master / expansion modules?
LED light patterns
Does Parker Hannifin have an LED status/error light pattern guideline for it's products in general?
Hello.
If you look trough the instruction books you will find that the blink panthers have roughly the same meaning on each of the current IQAN products.
The difference is if the unit in question have all the different blink codes or not.
There can also be a difference in the description of the error, this is why i said roughly.
For example, you have the blink code for output error 1:1.
On the MC2 it is only described as 'Output'.
On the XC21 it is described as 'DOUT error (open load)'.
This comes from that the only output on a XC21 is the DOUT and the only error detection we have on it is the open load.
On the MC2 we have more types of output channels that can generate this error so it is only described as 'output'.
These blink codes come from the MC3 instruction book.
Using these you can get a good idea of what is wrong with the unit.
1:1 Output
1:2 Input
1:3 VREF
2:1 Power Supply
2:2 Temperature
3:1 CAN, no contact
3:3 System mismatch
3:4 CAN error (bus off)
4:1 Internal error/OSE
4:2 Critical Temperature
4:3 Critical Stop
Measurement of current consumption on MC3 Vref
Is there a way of detecting how much current draw there is on the VREF supply on an MC3?
I have experimented with a SIL2 pressure transducer connected to an MD4 (don't have an MC3 to hand) and noticed that disconnecting the -VREF and leaving +5V supply and VIN signal wires connected to the controller will generate 2500mV signal into the MD4 VIN. This is not desirable as it simulates a pressure in the system which is not true. I can only imagine its how the internal electronic circuit is manufactured inside the transducer causing the false signal, but its not unique to one manufacture of pressure transducer. The current consumption of the sensor drops from 6mA to zero when the -VE is removed, wondered if this would be a good way to detect disconnected -VREF connection?
Aside from the method above or monitoring for a sudden change in VIN signal within the software, can anyone suggest any other solution to this issue?
