I have issue regarding CAN bus critical error on the MD4,

can any one suggest me to reification above issue.

I am waiting for your valuable reply. 

Good Afternoon, All,

I am working on an old Iqan transmission controller for a company that has since gone defunct.

Do any of the old timers around here know anything about an IQAN MC1606?

Does anyone know how I would go about cloning the project so that I can install it on another used module?

Any information on this obsolete controller would be appreciated.

Can I get CAD drawings of the IOT MKII

Good afternoon.

Some years ago there was available the electrical schematics such as for example IQAN-MD3_uk_electrical_schematic.

Are these still available as I am after a copy of both pdf and dwg for:

IQAN MD4 electrical schematic

IQAN MD4 electrical system schematic

IQAN XA2 electrical schematic

IQAN LC5 electrical schematic

I am having a problem with the open load detection on a COUT on am MC43FS

1. I am running IQANdesign 5.03.14.5040
2. The manual indicates that the output detects open load two different ways which may be true, but the controller responds in three different ways.
   1. When the output is off, if the load is disconnected, the controller will set the open load status to TRUE, when the load is reconnected, the controller will set the open load status to FALSE and allow normal operation.
   2. When the output is on and passing some normal current, if the load is disconnected the controller will set the open load status to TRUE and turn off the output, if the load is reconnected, the open load status remains FALSE, and the output remains off until the command is set to zero. Setting the command to zero causes the controller to reset the open load status to FALSE, after which the output will respond to a normal current command.
   3. When the output is on, AND some fault causes the resistance of the load to increase such that less than 50% of the commanded current can be pushed through the load, the controller will, set the open load status to TRUE and turn off the output. Unfortunately commanding the output to zero does not cause the controller to reset the open load status to FALSE. This acts like the open load status is latched to TRUE if it was tripped by “extreme saturation”
3. It is my belief the third response is a bug in MC43FS because, a MC2 running IQANdesign 4.07.7.4605 works as expected I.E. commanding the current to zero would reset the open load status to FALSE Such that the controller could lower the current and try again.

Hi, 

I have a applciation with alots of safety control Dout. 

Like i could read a the page 97 and 99 of the instruction book manuel of the MC43FS. 

We can have 5 Dout.

In safety function we need to combine one HS and one LS pin to a output. 

In Dout i have acces to 5 direcly and would need 6. 

I would like to know if it is possible to use the pin C2:71 HS and combine with a other LS for example C2:16 ? 

Else my other solution would be to use Cout as a ON/OFF signal output unidirectional. 

Thanks

I am trying to calibrate a level sensor that has a resistance output of 240 ohms (empty) to 33 ohms (full). The calibration below was what the setup is currently, but I am getting a high error on the VIN input. I am looking to fix the min and max, but I am unsure of how to scale this to voltage. I am getting a raw value of ~4999 at full. 

A customer has purchased a resistance output level sensor (240-33 ohms). I have tried to find more information regarding converting this to a VIN, but couldn't find too much. I am wondering what else needs to be done other than incorporating a voltage divider in their circuit.

Would it be possible to change VREF to 8V ?

I thought this would be easy to find but having no luck.  I have a request to read the outside ambient temperature on the MD4-7 and not having any luck finding anything to do this with.  If all else fails the standard ones I have used for hydraulic fluid might work in a pinch but unsure how accurate that would be.  If this is something anyone has any ideas on I would appreciate any feedback.
