Delta PLC with Single Phase inveter

Hello Everyone,
I've Delta DVP 20EXPLC. In this PLC, we can generate the pulsed outputs at Y0 and Y1. I wish to do the single phase inverter with the help of this pulses. Now, I am using four MOSFET which are going to operate the switches for inverting operations. Basic inverting operation is at that time pair of MOSFETs only should be on, remains or OFF. The problem for me is, When I'm giving the pulses from the PLC, the pulses of 4 MOSFETs are same, It cant operate with the above format. So, I didn't get inverted sine wave signal.
I hope that You can understand my status. If it is not sufficient, I am ready to explain deeply according to the reply. Please help me with out this problem.

What odes this have to do with LabVIEW? Do you have suitable high side drivers for the MOSFETS?

OR If any possibilites are there for controlling the MOSFETs from VI...?
Solved!

Hello,
You application that controlls MOSFET only requires the digital output that can be transmitted using any industrial communication protocol.
I checked information about Delta DVP EX and found it supports these protocols: Communication port: Built-in RS-232 and RS-485, compatible with MODBUS ASCII / RTU communication pro....
LabVIEW supports all of them. You can find examples for the first two in LabVIEW's Help - Find Examples ...
You can download Modbus support from NI product page.

Read velocity from QUAD-510 using single phase sensor

Hello, for my application I'm using a proximity sensor to count pulses using the CTR-400. To obtain velocity, I can make some calculations based on frequency or period but I was wondering if I can delegate this annoying task to the QUAD-510 module At the moment I'm able to read velocity using an encoder, but what if I use a single phase sensor like a proximity?

Hi,
Take a look at this document that talks about measurement with single phase and QUAD-510:

Does it mandatory to use Delta/WYE 3phase PDU for CRS1 8 slot deployment? Can we just use default single phase AC power-shelves?

does it mandatory to use Delta/WYE 3phase PDU for CRS1 8 slot deployment? Can we just use default single phase AC power-shelves?

The fixed power supplies (legacy / zone based system) require 3-phase AC-Delta/WYE.
The modular power supplies do not use a zone based system and require a single phase. You can order a CRS PDU to convert 3-phase AC input (from power source) to single-phase AC input for the power shelf.

How is it possible that a target has two deltas requests with the exact sam

HI,
How is it possible that a target has two deltas requests with the exact same records?

Hi Mohammed,
There are couple of reason behind it.
main reason is
take one scenario we have DSO as source and cube as target.
Now DSO contains only 1 request, which i have loaded to cube by using delta.
after that i have deleted DSO content by using right click on it and delete data.
(hope u know that it will not delete request from target automatically)
now once again i have loaded same request from datasource to DSO
and then loaded delta again from DSO to cube.
In this case for 1 single request in DSO you can see 2 request in cube with same data.

Measuring power at two different point (single phase)

Hi all,
I am new user of LabVIEW 2013 with electrical power suite.
May i know how to measure two different point of single phase system using the same VI such as in DAQ power and energy example?
As I notice that there are several type of wiring available. Is only one voltage and one current availabe during 1 ph voltage and 1 current selection. Thus, when I select 3ph voltage and 2 current, the value I obtain is not seem to be true.
From the figure attached, I want to measure the voltage at current at the solar/PV to obtain the power value. Other than that, I also need to measure the voltage and current at the load such as water heater. This is a single phase configuration network.
(2 voltage and 2 current measurement at single phase)
Hope for guidance.

Hi Lewis,
Here attached the file.
Actually I wanted to measure power two different point in a single phase system as shown in the first attachement.
Since, there is example in power quality measurement(DAQ) as shown in the second attachment.
since there is two measuring point in my measurement. May i know how to obtain two measurement voltage at the same time in DAQ?
Hope for guidance.

Error query.vi in my D6000 single phase

hello everyone , recently I am using the Labview 2009
I am running the program LEM D6000 single phase.vi
but in the Error Query.vi(inside D6000 Config Measurement block) there is always a mistake, Error 1300,, because after the VISA read , there comes in a number and compared to those constant number, first row and first column is 16, which somtimes is smaller than the number comes in , so it gives the comparison result as T, Error happens
so I changed 16 to 64, no more errors comes up
So I wonder what is the real function of Error Query is , and why shall I change the constant number to avoid the errors, although I make it work, but I want to know why.
Thank you very much

The error conditions and the Event Status Register should be documented in the instrument manual. Not sure where to start with the basics. There are individual bits in the ESR and the instrument will set specific ones depending on the actual error that the instrument detects. Are you familiar with Boolean math? Bit number 4 reflects a specific error. If you want to check to see if the bit is set, you would AND it with decimal 16 or binary 10000. If bit 1 is set, the result of the AND is 1. You decided to AND it with 64 (a check of bit 5) and by doing that, you are no longer checking to see if bit 4 is set. That is ignoring the error. If you want to ignore any errors, don't run the error query program. Changing the code is just plain wrong.

Single phase inverter controlled by compactRIO

Hi guys, I am conducting my application which need a single phase grid-tie inverter. I want to find a custimized or commercialized single-phase grid-interactive inverter which allow the user to define the control algorithms. I wish I can controll this inverter on Real Time by my CRIO since I have already get these analog/digital I/O modules with my CRIO.
Do you guys any any recommendation for which inverter I can find to achieve this kind of function? or any other suggestion for my application.
BTW, I read there's some NI product called NI Single-Board RIO General Purpose Inverter Controller. Is that one have some specific function for inverter which CRIO doesn't have or it is just a single-board RIO which has similar function with a normal CRIO?
Peter

Hello sdualienware,
The functionality of the Single-Board General-Purpose Inverter Controller (GPIC) is defined by the code deployed to the hardware and may in fact, be used with a normal CompactRIO. I have included a few helpful links below that will not only help to explain the functionality and benefits of using the NI-RIO technology to perform this control (although most resources specifically point to the Single-Board RIO), but also provide sample code that may be used for single-phase inverter control.

Using LabView to create a GUI for Delta PLC

Hi,
I'm currently using a Delta PLC, programmed with the Delta WPL software, and I'd like to use LabView to create a very simple GUI which would allow the user to communicate with the PLC (basically, the PLC would be running but doing nothing til the user writes data in one of the coils). I don't know how to do that, and I don't even know if it's possible ?
The PLC I'm using supports Modbus. I tried to use the Modbus library from LabView but I'm not sure it's useful for what I'm trying to do.
Any idea ?
Regards,
Coline

The Modbus library can certainly be used to read and write registers and coils. You just need to know the relevant details for your PLC (address, coil addresses, ASCII/RTU, etc.) and to make sure the PLC is configured to accept these commands.
The Modbus library should have a couple of examples showing how to act as a Modbus master, which is what you want.
Try to take over the world!

You have a voltmeter with 10 Megohm internal resistance in series with the output so no current can flow. Take out the voltmeter and the circuit works.

K7n2 delta ilsr with kingston pc333

Owning a MSI K7N2 DELTA ILSR with an AMD ATHLON XP 2800+ and 512mb DDR KINGSTON (KVR333X64C25/512).
I like to run the motherboard with a FSB of 166MHz, with a 12.5 multiplier.
Setting the FSB/DRAM to 1:1 gives no troubles at all.
But FSB/DRAM 1:2 will lock up the booting process and the only way to escape the black-screen-of-nothing is to reset the bios with the jumper :-(
This way I run half the speed my memory is capable of!
Somebody a suggestion?

memory and cpu uses ddr to transmit data.
double data rate.
it means it sends data twice each clock cycle instead of one.
166mhz true transfer rate becomes 333mhz virtual transfer rate.

Configuring JCo3 Connection Pool with single sign on on non SAP Java server

Hi Everyone,
i have configured a connection pool on JBoss as per JCo3 Documentation and is working great.
Now I need help to configure this connection pool with single sign on so that RFc on SAP ECC systems are executed using end users credential rather than using single user name password used to configure JCo connection pool.
On SAP Java stack I am sure its possible within Java WebDynpro and i assume using JCA resource adapter. But what if we don't want to use SAP Java App server.
Any help will be appreciated.
Thanks,

Dynamic SQL and Data with Single Quotes in it.

Hi There,
I have a problem in that I am using dynamic SQL and it happens that one of the columns does contain single quotes (') in it as part of the data. This causes the resultant dynamic SQL to get confused as the single quote that is part of the data is taken to mean end of sting, when in fact its part of the data. This leaves out a dangling single quote that was meant to enclose the string. Here is my dynamic SQL and the result of the parsed SQL that I have captured:
****Dynamic SQL*****
l_sql:='select NOTE_TEMPLATE_ID '||
'FROM TMP_NOTE_TEMPLATE_VALUES '||
'where TRIM(LEGACY_NOTE_CODE)='''||trim(fp_note_code)||''' '||
'and TRIM(DISPLAY_VALUE)='''||trim(fp_note_text)||''' ';
execute immediate l_sql INTO l_note_template_id;
Because the column DISPLAY_VALUE contains data with single quotes, the resultant SQL is:
******PARSED SQL************
select NOTE_TEMPLATE_ID
FROM TMP_NOTE_TEMPLATE_VALUES
where TRIM(LEGACY_NOTE_CODE)='INQ' and TRIM(DISPLAY_VALUE)='Cont'd'
And the problem lies with the single quote between teh characters t and d in the data field for DISPLAY_ITEM. How can I handle this?
Many thanks,

I have been reliably informed that if one doesn't enclose char/varchar2 data items in quotes, the right indices may not be usedI am into oracle for past 4 years and for the first time i am hearing this.
Your reliable source is just wrong. Bind variables are variables that store your value and which are used in SQL. They are the proper way to use values in your SQL. By default all variables in PL/SQL is bind variable.
When you can do some thing in just straight SQL just do it. Dynamic SQL does not make any sense to me here.
Thanks,
Karthick.

AP Tax Calculation issue with SINGLE TAX vs TAX GROUP

Hi Gurus,
i need your help on below, please advise!!
i have to calculate ap VAT tax on AP invoice,
(Rounding = nearest, precession=2, tax calcualtion= Include tax)
if i calculate 5% is the tax rate, then the tax amount is 0.47cents,this is in case of single tax calculation.
here my requirement was i need calculate 2 Taxes(TAX A AND TAX B (Rates are 5 AND 5%)
EG:
Invoce Base amount = 10 dollars
in case of single tax = 5/105 * 10 = 0.4761 cents(this is 48cents in apps with rouning nearest and precession 2)
tax mode = Include tax
In case of tax group = Tax A and Tax B = 5 + 5 = 10%, when i calculate this in apps its showing 45cents and 45 cents as tax A and B
why this tax caluclation is different with single tax and tax group.
tax code actual amount tax amount remaining amount
single tax 10 0.4761 10 - 0.48cents = 9.52 cents
tax group 10 45+45=90 cents 9.10 cents
Please Help !!!
Thanks,
Satish

Hi Vineeth,
This is Kathy from BSI Support. I wanted to make sure that you understood that the TF80 Like Reciprocal flag was made available in TF90 for testing purposes only. This was meant as a tool for customers to be able to compare their TF90 results to their TF80 output, to insure a successful upgrade. This funcitonality, however, was never intended to be utilized going forward. There have been significant changes implemented in BSI TaxFactory 9.0 regarding multi-state withholding (also known as reciprocity). There is information available on our website that explains these changes. If you log onto our website, please look under the "Whats New" section for an explanation of reciprocal functionality in BSI TaxFactoryu2122 9.0
If you have specific scenarios that you need help with, please contact us and we will be happy to assist you.
