Convergence error on counting circuit

Ignore all the extra stuff, alot of it was for troubleshooting so it looks messy. It seems to give me the error when i hook the 7 segment display up to ground. If i just let it run without it connected, the leds light up approprately. As soon as it's connected, i get convergence. I tried all the time step stuff too. No luck.

Here's what I found. Goto SIMULATE>DIGITAL SIMULATION SETTINGS and change itr from IDEAL to REAL. This will require you to place the following power sources on the schematic somewhere: VCC, VDD, DGND, VSS. This should get it simulating without the error message popping up.
I do not know why the 7-seg displays don't work under the IDEAL Setting, but most of the time I have observed that they don't. Usually when I am going to use them I have to set the simulator up as described above.
I hope this helps

Table creation Error "Ref Count for this object is higher than 0"

Hi All
I have a problem in creation of table using SDK on a button event. I have a procedure to create tables and fields. If I call this procedure on a menu Event than it works fine but If I call this procedure on a button event than It gives error "Ref count for this object is higher than 0" . I know this error occur When an object does not release after creating a table. but this error occur at when first table is created. My code it given below. plz see and give me your valuable suggestions.

Hi Gorge,
The "Ref count error..." usually occurs in case of Meta Data objects not being properly cleared. And yes, you have got the error in the right place, generally while creating tables / fields / UDOs. For this, you just need to clear the Meta Data object (At times even DI objects like Record Set) once they are used.
Eg: Release these objects in the below way in a Finally Block.
System.Runtime.InteropServices.Marshal.ReleaseComObject(oRecordSet);
Hope this helps.

Error: Ref count for this object is higher then 0

Hello All,
I am trying to create User Defined Tables in SAP through Coding but while running the code the error "Ref count for this object is higher then 0 " is showing .
I have created a temporary table in which the Table Description are stored as follows :-
Create Table Test_Table (TblCode Varchar(30),TblName Varchar(100),TblType int)
From this table then using recordset i am getting the table details for creation :-
oRecord.DoQuery("Select TblCode,TblName,TblType From Csv_UDT")
            While Not oRecord.EoF
                Dim Table_Id As String = oRecord.Fields.Item("TblCode").Value
                Dim Table_Name As String = oRecord.Fields.Item("TblName").Value
                Dim Table_Type As integer = oRecord.Fields.Item("TblType").Value
                Dim oUserTablesMD As SAPbobsCOM.UserTablesMD
                oUserTablesMD = Class_OprTbl_Main.ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserTables)
                '// set the table parameters
                oUserTablesMD.TableName = Table_Id
                oUserTablesMD.TableDescription = Table_Name
                oUserTablesMD.TableType = Table_Type
                lRetCode = oUserTablesMD.Add
                If lRetCode <> 0 Then
                    If lRetCode = -1 Then
                    Else
                        Class_OprTbl_Main.ocompany.GetLastError(lRetCode, sErrMsg)
                        Class_OprTbl_Main.SBO_Application.MessageBox(sErrMsg + oUserTablesMD.TableName)
                    End If
                End If
                System.Runtime.InteropServices.Marshal.ReleaseComObject(oUserTablesMD)
                oUserTablesMD = Nothing
But while running this code the error is coming .
How to solve this error ........
Thanks,
Amit

First of all, you are not meant to create temporary table in SAP database. SAP have never made an official announcement, but I think they would not be too happy if they saw it and may withdraw support. Just something to be aware of.
Secondly, your error is very common and you would have found the solution by searching the forum. It is caused by having an open recordset while trying to use a metadata object.
You will have to change how your code works. You can not use the UserFieldsMD or UserTablesMD object while you have an undisposed recordset object.
-1120 - Ref count for this object is higher then 0
Ref count for this object is higher then 0
Error: Ref count for this object is higher then 0
Meaning of Error Msg: "Ref count for this object is higher than 0"
The solution is you must dispose of any recordset object before attempting to use the UserTablesMD object:
System.Runtime.InteropServices.Marshal.ReleaseComObject(oRecordSet)
oRecordSet= Nothing
GC.Collect()
GC.WaitForPendingFinalizers()

000 to 999 counter Circuit LCD Not working Help

I am trying to outline the design for my project for my circuits class I am pretty new to Multisim, but I have tried everything to get the 7 segment 4 digit LCD and or 3 7 segment Hex to display properly I am not sure if its something wrong with my circuit orthe software. I hooked a logic analyzer to the outputs of the counter 4516B IC so I know that it is counting. There must be a error in the way I am connecting my driver 4543s Please help so that I can begin physically building this circuit and wire wrap.
Thanks in advance.

Have a look at the attached file; I've isolated the two parts you mentioned so that you can see how they work. Press the key A, B, C and D on you keyboard to control the inputs DA to DD and you can see the results on the 7 segment display.
U17, I've turned on the symbol pin name so that you can see which pin is which. A1 to G1 are part of the first 7 segment LED.
Here is a datasheet for the 4543:

HB Convergence problem in EM-circuit co-simulation

Hi,
It would really be very helpful if someone could take a quick look at the simulation problem in the attached project. I keep getting the simulation errors - "Step size for source stepping has decreased below a minimum allowed value." and "Poor convergence in AC/DC analysis (rel/abs err = 2.000 / 0.000 ) Largest change in node (41) Maximum voltage in node (46) = 53.076 Minimum voltage in node (MET_BASE!_S12_LD1.R1.ET) = -4.337 Largest change in branch (_S12_S1.I16) Maximum current in branch (_S12_S1.I17) = 951.567m Minimum current in branch (MET_BASE!_S12_LD1.R1.Bessel_L1.I) = -1.735"
despite trying out most of the suggested solutions listed in the help for the particular error message, the problem persists. What am I doing wrong here in the simulation setup ?
Thank you very much in advance.
Solved!

A few problems with the project:
The harmonic balance frequency spectrum includes DC (frequency=0), but your s-parameter models do not include data at 0Hz. So Microwave Office is extrapolating the data down to DC. The best solution is to add a 0Hz matrix line to the data. You can also try alternate interpolation techniques in Options > Project Options > Interpolation/Passivity tab; try Rational function and Cartesian, or Linear and Polar.
We recommend using the APLAC simulator for harmonic balance analyses. From the menu, select Scripts > Simulation > Convert_Meas_to_APLAC. The default settings should work fine.
You only need the "PA LS Sim_Real Ckt_check" schematic.
With the EXTRACT block enabled, it is the same as "EM_Ckt Co_Simulation_Nonlinear_Linear". You can make linear measurements on a nonlinear schematic. (Generally, you should not use extracted EM structures as a SUBCKT in other schematics. If you ever need to do something like this, make a copy of the EM structure to eliminate its association with the originating schematic, and use the copy as a SUBCKT.)
With the EXTRACT block disabled "PA LS Sim_Real Ckt_check" is almost like "PA Final ckt_Pgain_AM_PM". You just need to change the port to sweep power. For measurements that you want to make at 20dBm, rather than with swept power, just choose the desired input power level on the measurements. (Why did you disable the layout on the microstrip elements in this schematic?)
In this project, you can use one top level schematic for all measurements. We recommend a "testbench" approach when you need to perform different tests (e.g. 2-tone or pulse input, different biasing topologies, etc.). By this, we mean using the same circuit schematic as a SUBCKT in one or more top level testbench schematics. This way, you only edit the circuit in one place, and do not have to manually keep duplicates in sync.

I don't think there is any way to modify your table definition to accommodate the (apparent) fact that missing values generate nothing in the file you want to load.
It seems that you are saying that the format of the file is not actually fixed in any way, that is has some, but not all values, and that mising values are just skipped.
Assuming for a moment that the fields are delimited bt a pipe symbol (|) then it seems to me that you have this situation :
Defined file format:
ID|name|age|addresswhich would imply the file should look like:
123|John|42|123 MainSt.
456|Fred|39|45 Pine St.but sometimes you get:
12345|27|12 Elm St.If this is the case, there is no possible way that the file can be reliably parsed since there is no consistnet format. If field values could be missing, you need to get whoever generates the file to do something more like:
12345||27|12 Elm St.That is, put in the field delimiters even if there is no value for the field.

How to solve the error "Ref Count for this object is greater then 0"

Hi,
I'm trying to add UDF at runtime to an already created UDT which is of No Object Type.
my code is as follows:
dim oUserFieldsMD As SAPbobsCOM.UserFieldsMD
oUserFieldsMD = ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserFields)
oUserFieldsMD.TableName = "@TI_ADDCODES"
oUserFieldsMD.Name = codetoinsert
oUserFieldsMD.Description = desctoinsert
'Add the field to the table
   lRetCode = oUserFieldsMD.Add
   If lRetCode <> 0 Then
   ocompany.GetLastError(lErrCode, sErrMsg)
   MsgBox(sErrMsg)
    Else
    MsgBox("Field: '" & oUserFieldsMD.Name & "' was added successfuly to " & oUserFieldsMD.TableName & " Table")
    End If
I got error msg as "Ref Count for this object is greater then 0" and error code is -1120
how to rectify it?
Thanks in advance!!!

Hi,
Have you searched the forum? You may check this first: error -1120 when adding UserTableMD.

Error in counting.

Hi,
I am using the measure buffered period vi from LV 6.0 to measure the time averaged period of a square wave. I am using the signal as the gate and the internal clock as the timebase with a frequency of 100KHz. The problem i am having is that the VI does not produce the right output. About 60% of the time the value is right but the other 40% it is wrong and it seems that it is missing a pulse from the signal and counts double the period/ half the frequency. I am not sure why this is happening. Also this error gets worse as i increase the time base. I have grounded the signal appropriately so that shouldnt be an issue. Is there any way to rectify it? Is there some technique using the other counter i have on the board (pci-6052e) to resolve this.
Thanks in advance,
Shyam Menon.

Hi Shane,
I should have done this before but i am posting a section of my code now. The top parts are about scanning the analog channels connected to my scxi 1120 module and the bottom part is for scanning the counter pin. Since i read the pci-6052e has 3 dma modules, i shouldnt hopefully have problems with data transfer. Another thing i found is that i need to have sufficient delay time in the read buffer vi so that all the data gets written to the file otherwise i am missing some of the data. Hope this helps you to understand my problem better.
Thanks,
Shyam.

1086 Syntax Error (on Counter.fla)

Can anyone elaborate as to why I am getting an error with
this "counter script" (counts down Years, Months, Days, Hours,
Minutes, Seconds)? The error is "

50), but after doing research on the error number and looking at
the actual error line, it appears that it may be something other
which I am not seeing?
HERE is the Action Script I am using:
this.addEventListener(Event.ENTER_FRAME,onEF);
function onEF(evt:Event):void {
var today:Date = new Date();
var currentYear = today.getFullYear();
var currentTime = today.getTime();
var targetDate:Date = new Date(2011,10,16);
var targetTime = targetDate.getTime();
if (targetTime - currentTime > 0) {
var timeLeft = targetTime - currentTime;
} else {
var timeLeft = currentTime - targetTime;
var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hrs = Math.floor(min/60);
var days = Math.floor(hrs/24);
var months = Math.floor((H+L-7*M+114)/31);

200301 error for counter update

Hi everyone,
I am running a PID loop to control temperature in a box. The counter closes a solid state relay and thus powers my heater. I use a PCI 6221 card.
I keep getting the following error:
Error - 200301 occurred at DAQmx Write (Counter Frequency 1Chan 1Samp).vi:1
Possible reason(s):
Measurements: Cannot update the Pulse Generation property.
The pulse generation with previous property settings must complete a full cycle before the property can be updated.
The code consists of a loop running every 100 msec which adjusts the duty cycle via a property node and then performs a DaqmxWrite on the same channel to force the new property settings to take effect. I have used a Daqmx Clear Task at the end of the vi, but the error occurs randomly every now and then. The pulsing is at 10Hz.
I believe it might have something to do with my computer, since any time I open another program (Firefox for example, or Origin) while the program is running, it gives the error. I think maybe the computer cant handle all the tasks at once?
Any ideas what could be wrong here? I've attached my vi below... it could be the PCI card...

PIDPWMtemperature.vi ‏74 KB

Hi HessenMob,
It looks like your VI is based on an example from the example finder (help => find examples => browse => Hardware in and output => DAQmx => control => General => PWM counter output.vi ). With the example from the example finder they are synchronizing the counter to the AI sample clock. The while loop is waiting until the next sample from the sample clock, so also your loop runs at the specified rate.
The PWM will only be updated (so counter task is hardware timed single point) when the value of the PWM signal needs to be changed. With continuous you need to write fats enough values to the counter.

Get-Counter failing with error : A counter with a negative denominator value was detected

Hi,
I cannot reproduce your issue either. It seems like that this issue a issue related with your environment.
Based on the error message "A counter with a negative denominator value was detected", it seems like that
$iterations sometimes is treated as a negative number. How about change
[long] $sum=[long]
($sum/$iterations)
as
[long] $sum=[system.math]::abs([long]
($sum/$iterations))
