Controllers / Re: DigFeedBack SC050 active without coil connected
« Last post by sverreo on November 12, 2023, 04:00:10 PM »
macbahi, why can't DigFeedbak=1 if there is an open load on the pin?

DigFeedback measures the voltage on the output pin, and there should be power there even though there is nothing connected (Open Load) as long as DigOut=1

Hello Lukey,
You can send the GNSS position by setting the parameters of the CAN messages transmitted by the service tool :


I hope I've helped you.
I'm sending you the CS500 diagnostics file.

Controllers / Re: DigFeedBack SC050 active without coil connected

Hello again,

Sorry I am not agree with you. DigFeedback is not correct.  Please see good first picture .
It's not possible the DigFeedback can be on in both cases load connected and load non connected   (load is coil).

Moreover status indicate 0.  It's good result load connected but for Load non connected status indicate 8. So DigFeedBack must be 0.  Please see the picture.

I think some SC050 DigFeedBack has error problem.  In the past I use the same program with SC024.  It's working good.
Now I want to use SC050 but I find this error feedback.

For the moment I use Status as feedback but it's not good solution because status =8 is for over temperature and open load.

It's same problem for multi-function output but in this case it's status problem.  Please see good the second picture.

with best regards
macbahi

From my understanding DigFeedBack is correct. The description of DigFeedBack in the API specification is: -
The actual measured level on the digital output.
If DigOut is Ture and the output is not being disabled by the safety layer the pin will have supply voltage regardless of whether it is connected or not.

I tested a DigOut pin and a Multi Function pin in the different configurations (DigOut, DutyOut, CurrentOut & PVEOut) with nothing connected and see the same result that Status always = 0.

Hello,

Thanks for reply.

Yes it's correct when status=8,  it's open load but why DigFeedBack is ON for both cases open load or close load.

All digital output are the same problem however all multi-function digital output use FeedBackcurrent and also problem problem with status.

As resume all digital output has DigFeedback problem and all multifunction digital output has stutus problem

Please analyse rightly the result in the picture.

Any way I communicated with danfoss for this problem.  I wait for your answer.

Best regards

A status value of 8 is Over Temperature/Open Load Detected. If you have nothing connected to the pin the status is reporting the open load.

Controllers / DigFeedBack SC050 active without coil connected
« Last post by macbahi on November 09, 2023, 12:05:29 AM »
I have a safety controller using a digital output as example (C1p36) or 37 or others.
now without connected to coils the digFeedback is usually 1  when digOut is set.
The status is 8 (over temperature).
I make off the controller for long time when I start it is the same problem.

Please Can you tell me what is the problem?

Thank you very much
With best regards

PLUS+1 GUIDE / Re: ST coding and Initial Value of Var
« Last post by FluidPowerTom on November 08, 2023, 05:18:57 PM »
I do this programmatically by having another variable function as a sort of default-setting flag:

FUNCTION_BLOCK BrakeLogic
VAR_INPUT
  BrakeTimerSetting2 : USINT;
  SetDefault : BOOL;
  SaveChanges : BOOL;
END_VAR
VAR_OUTPUT
  BrakeTimerSetting : USINT;
END_VAR
VAR
  startup : BOOL;
END_VAR
VAR RETAIN
  BrakeTimer : USINT;
  NVMem_Init : UDINT;
END_VAR

-----------------------------------------------------------------


IF SetDefault OR NVMem_Init<>666666 THEN
  BrakeTimerSetting:=0;
  BrakeTimer:=0;
  NVMem_Init:=666666;
END_IF

IF NVMem_Init=666666 AND NOT startup THEN
  BrakeTimerSetting:=BrakeTimer;
  startup:=1;
END_IF

IF SaveChanges AND NVMem_Init=666666 THEN
  BrakeTimer:=BrakeTimerSetting2;
  BrakeTimerSetting:=BrakeTimerSetting2;
END_IF


EDIT:  As you'll see in this case I'm using a variable named NVMem_Init for that, and we initialize the BrakeTimer as 0.

PLUS+1 GUIDE / ST coding and Initial Value of Var
« Last post by federico.furlani on November 08, 2023, 10:46:39 AM »
Hi everybody,
I'm struggling with using the ST code on Guide. In particular, my problem of the day is to initialize a retain Var.
How can I access the 5 as Initial Value?

Thanks

Displays / RTC adjusting itself
« Last post by sverreo on November 01, 2023, 11:57:34 PM »
Does anybody else have issues with the RTC adjusting itself on the dM1000?

In the HWD files there was new features to add timezone, and "Auto" adjust.
Even if the "Auto" is False, if i adjust the RTC it automatically change after an hour or so after i set new time...

i see in the latest HWD 321 template they have removed the option with timezone and "auto"
