i need ur help

i need to biult system that can be measure pressure from sensor i have the transfer funtion

but i try to make it but it does not work

i need to save data in excel file and in same time i need to display the reading of pressure in table by front panel

table conssit of (date\time\value).

also i need to make excle file save data day by day not all of them in same file

thanx for all

It's going to be almost impossible to help you unless you give more details of the hardware that you are working with - how do your sensors connect to your computer ? What so of signal do they return ?

People on LAVAG are generally helpful, but are much more likely to help those that try to do something for themselves first, so I suggest you post what code you've managed to write already, even though it doesn't work.

Or you might find that asking your teacher or instructor is a more profitable route to getting solutions to your assignments.

Start with the shipped LabVIEW examples, just open the example pages and search for a few words:

'Excel', 'Table'.

For getting the data if it used NI-DAQ or NI-DAQmx look in the examples as well and start easy, perhaps use the Express VI provided by NI.

If you have a non-NI DAQ board try to get some example programs.

PS your question title is a little to vague, be more precise 'Help me getting data in a table' or 'Help me get data from a transducer type XYZ'

PPS your question title is written in slang, normally I just ignore those since it looks like you are lazy

hi i need ur help i need to biult system that can be measure pressure from sensor i have the transfer funtion but i try to make it but it does not work i need to save data in excel file and in same time i need to display the reading of pressure in table by front panel table conssit of (date\time\value). ..

You can format your date into strings and build an array out of them. Then build a 2D array form multiple array from separate measurements. This 2D-Array can be displayed using the table indicator.

.. also i need to make excle file save data day by day not all of them in same file thanx for all

Simply start a new file every day by adding the date to the file name. If the day changes the file name changes as well (as long the clock in the computer is working correctly (empty buffer battery)). You need to open and close the file for each or a couple of measurements. And the access need to append data. At the moment I don't overlook how this is done with Excel. In case of doubt you need to store the last location where wrote your data (and if your programm is started repeatedly you will need a configuration file to store it). Increment the location with writing the next data.

i am try from one example and one topic in this site

but it does not work can u help me

i have 2 error plz see attachments

1 more qustion plz

i want to make a report i try that but i Fail

1st try .vi

If you double click the lines in the error list (the picture that you posted) LabVIEW will automatically show you the errors on the block diagram.

The reason you have the errors are that when you use a case structure you must specify an output for each case for every tunnel .

At the very least you need to select Use Default if Unwired .

See how you go with the above information.

By the way, you are missing a subVI in your attachment "multiple time delay match.vi"

it is there

Double click on the error (missing assignment...) and LabVIEW will show you where is the problem. Here you didn't wire anything to tunnels on "False" diagram of Case structure. You may either wire something there or let LabVIEW use default values by right-clicking on tunnel and checking "use default if unwired". Generally if you have tunnel marked as empty rectangle, you'll have error there.

jgcode : mind connection?

am try from one example and one topic in this site but it does not work can u help me i have 2 error plz see attachments 1 more qustion plz i want to make a report i try that but i Fail

Ok, your immediate problem (aside from the missing sub-vi) is that you are generating some outputs in the case structure inside the while loop, but only when that case is true. When the case is false the two wires coming out of the case structure don't connect to anything inside the false case. You can see that this is the problem because the 'tunnel' where the wire goes through the case structure boundary is white not solid colour.

However, I suspect that you have a larger lofic problem in your code as the bit where you are trying to save the log file to disc will only execute when the whole measurement loop is finished and then will only write the very last measurement to disc.

Your probably want to move the code that builds the table and and also save the file into the inside of the case structure in the while loop.

Nice one! What are you doing write now? I am trying out these Community Scope class with X-controls, are you ?

I'm also trying! But I'm trying to convience damn print head to produce some droplets for me. I'm giving it such a nice waveform and the only thing I get is bzzzzzzz

Close.. but no cigar

Commit Failure While Configuring Tunnel Monitor

On the Palo Alto Networks firewall, there were problems configuring the Tunnel Monitor. The firewall is throwing a commit error while applying the change. When committing the configuration, the following error appears:

" IPSec tunnel "tunnel-name" enabled tunnel monitoring while binding to tunnel interface "tunnel-id" which has no IP address assigned to it yet. configuration is invalid. "

Environment

• Palo Alto Firewall.
• IPSec VPN configured with tunnel monitoring.
• PAN-OS 7.1 and above.

The Tunnel Interface needs an IP address in order to enable Tunnel Monitoring.

If the IPSec Tunnel is configured as the scenario shows below, notice the tunnel interface does not have an IP address it will give an error. The Tunnel Monitor needs to be enabled so that the IPSec tunnel always remains up. It can also be used for redundant VPN scenario.

The Tunnel Monitor can be configured from the WebGUI, go to Network > IPSEC Tunnels , click Add and give the VPN a name and select Show Advanced Options:

The Tunnel Monitor uses PING packets to monitor the VPN tunnel connectivity sourced from the Tunnel Interface IP. So, it is mandatory to configure tunnel IP when configuring tunnel monitor.

Go to Network > Interfaces > Tunnels > (select configured tunnel Interface)> IPv4 , click Add and enter an IP address. A dummy IP address (not used anywhere in the network) can be used to configure the tunnel interface, as shown below:

Additional Information

For more options to configure Tunnel Monitor, refer to the following document: Selecting an IP Address to use for PBF or Tunnel Monitoring

在LabVIEW的For循环和While循环中使用自动索引隧道

适用于, 软件, 问题详述, 解决方案.

相关信息

• 如果两个不同长度的数组通过自动索引的方式连接至For循环中，则长度较短的数组的元素个数决定循环的次数。示例：两个数组元素个数分别为4和8的数组被自动索引到For循环中，则循环执行次数将为4次。
• 如果两个不同长度的数组通过自动索引的方式连接至While循环中，那么它们都将被索引，直到循环结束（由条件接线端决定），而且当数组没有数据后，在后续的每次迭代中，数组元素的数据类型的默认值将自动填充为数组的其余部分。 While循环具有独立于数组的停止条件，因此编写程序时需要注意在适当时停止While循环，从而避免将错误数据添加到输入和输出数组。

Tunnel-Assignment-ID

This attribute is designed to specify which pre-configured tunnel a particular connection should use. More specifically, some tunnel protocols allow for multiplexing multiple connections across one specific tunnel, and with this attribute, RADIUS can inform the initiator (the client, in other words) whether the connection will be over an individual tunnel or a multiplexed tunnel.

There are specific behaviors a tunnel initiator should follow when using the Tunnel-Assignment-ID attribute:

If a tunnel exists between the specified end points with the designated assignment ID, then the session should use that tunnel.

If no tunnel exists between the specified end points with the designated assignment ID, then a new tunnel should be created and referred to as the label indicated in the Tunnel-Assignment-ID value.

If the Tunnel-Assignment-ID attribute is not present, then the session should be assigned to an unnamed tunnel. If this tunnel doesn’t exist, it should be created and used for all sessions that don’t have the Tunnel-Assignment-ID attribute.
