How? Sorry but its pretty simple, i want to issue a command to an external device every 5 seconds. I however do not want to put the entire threat to sleep for 5000ms.
thanks guys,

How can I execute a command every 10 seconds in a specific time-frame

Hello,
I would like to create a script which in a specific time-frame collects some outputs and also pings every 10 seconds.
To collect the outputs every minute from 22:00PM to 22:10PM I have the following:
event manager applet snmp_output
event timer cron cron-entry "0-10/1 22 * * *" maxrun 30
action 010 cli command "enable"
action 020 cli command "show clock"
action 030 cli command "terminal exec prompt timestamp"
action 040 cli command "show snmp stats oid | append bootdisk:show_snmp_stats_oid.txt "
action 045 wait 5
action 050 cli command "show snmp pending | append bootdisk:show_snmp_pending.txt "
action 055 wait 5
action 060 cli command "show snmp sessions | append bootdisk:show_snmp_sessions.txt "
acionn 065 wait 5
action 070 cli command "end"
To confirm connectivity to the device doing the SNMP polls I would like to execute a ping every 10 seconds in the same timeframe.
Cron seems only to support minutes. Is it possible to combine a watchdog timer + a cron timer?
Can this ping function be incorporated in the SNMP output applet or will I have to write a new one?
Will I need TCL here (I have no experience in TCL)?
Best regards,
Tim

If you wanted the pings to run in parallel, you could have this applet configure another applet to do the pinging, then remove it on the last run. This will require an amount of programmatic logic, though. If you wanted to keep things a bit simpler, add another applet that runs at 22:00 that configures a watchdog pinging applet, then a third applet that runs at 22:10 that removes the pinging applet.
When it comes to embedded quotes when you configure your nested pinging applet, you'll need to use $q to stand for the embedded quotes. You'll also need to configure:
event manager environment q "

Sending ASCII commands by tcp to wireless device

Hi to all. I have some AVL (automatic vehicle location) devices. I work with them through GPRS by USB modem (Compass 885). I read data from them through UDP port and everything works fine. But I have to send a commands to the devices by TCP and I don't know how. All of examples are not helped. Ping test to IP of device is OK. Hope to your help.

You have the pointer to nmap. But you could just try any search engine for more info. That is now in your task to deal with the protocol for communication. We can point you to how to use LV, how to find out certain information but you need to do the specific work for your task. What port your AVL is on, is information specific to your problem. It was a design choice by whoever wrote the software/firmware for the AVL device.
nmap is a powerful tool and with great power comes great responsibility. It is used by hackers and network administrators. The full use of nmap is beyond this discussion group but you can use the link for more information. This is not as good a solution as asking the designers for their communication protocol. It is designed for communication and so it would be absurd not to publish it in a manual or keep it secret.

Sending GPIB commands

Hi,
How to send string commands to GPIB(IEEE488) from PC?
The functions "GPIB CMD" and "MISC" not working.
If use: "cmd 4+0 4" not answer. Why?
Duke

Duke,
I'm not exactly sure what message you're wanting to send to the device; I am not familiar with the BASIC syntax that you are referring to, especially since all your reads, writes, and commands start with the "LISTEN" directive?
As you may or may not know, you can address a GPIB device to send data or to send a command. To address a device and send data (like a "*IDN?" or some sort of query for measurements), you will want to use GPIB Write and GPIB Read VI's. For commands, you can use GPIB CMD. However, the command value 4 doesn't make much sense by itself. "4" stands for "Selected Device Clear" in the GPIB multiline messages.
Should you be sending the "4" command (Selected Device Clear)?? Or just the 4 data? If you want to send the
command, you probably would send a "talker aa, Listener xx, subaddress yy" command to the bus to specify where you want the command to be sent, where aa is the GPIB address of your board, xx is your device's gpib address, and yy is your device's sub address. Look in the links below to construct a string of gpib commands that do this, then you can feed this string into GPIB CMD.
This link has information about low-level GPIB commands that may be helpful:link
Here is some getting started info for IBIC, a text-based interactive control for GPIB interfaces that may allow you to experiment to see what exact GPIB command will do what you want: link
Hope this helps.

Sending AT command from xbee pro to read the data from device

I am new to serial communications using Labview.
I am having trouble with starting up the project, where I have to design the software that involves XBee pro module.
I need to send the READ command to read the data from a device. Then the software should go to the AT command mode (we enter the AT command mode by entering +++)
Then I need to read the energy level of the device by entering the command: ATED. The software should continuously read the energy level every 30 seconds, which will be displayed on the front panel.
I am not sure where to start the software from. i.e. how to enter the Read command and then the AT command.
I am hoping someone can suggest how to start this.
Thanks in advance.

Hello Manny,

Receiving message"There was a problem sending the command to the program" every time I access a website using a desktop icon via Firefox.

When I click on a desktop icon and access a site via Firefox I get the message "There was a problem sending the command to the program". This started to happen after I downloaded the most recent version of Firefox. I uninstalled Firefox and reinstalled it and the message still comes up every time. The site will come up about three seconds after the message appears but the message is a real pain to put up with. What is the problem? I am ready to dump Firefox and go to Opera.

How to search for BT device automatically every x seconds?

I have a Trust BT-2100p which came with the Toshiba Bluetooth software.
I can connect my Bluetooth remote control to my HTPC, but when I disconnect and want to reconnect again, I have to right click on the device, press "connect" and then "OK" in the popup window before it starts searching.
The whole point with the remote is that I don't need a keyboard or a mouse.
I can make a simple .bat-file that starts the connection automatically every x seconds, but it can't press the "OK" button.
Is there a way to make it search for the device automatically every x seconds?

HID devices are automatically connected as soon as a button was pressed on it. I checked the internet regarding your WII devices. The problem in your case is that this devices supports a none standard function which must be configured first in oder to reconnect by HID automatically. So this has to be done by the software which you mentioned. It has to configure the controller which should be used. This device support 4 of it.

This is the module in our eMac 1.42:

The vendor, Other World Computing, ships to the UK but I suspect the shipping would make it pricy. I also trust this vendor:

Between the two vendor's description, you should have a good idea of the Specs
PPC Macs do not like hi-density PC RAM. That's why I linked these two; they send the right stuff to Mac users.
Crucial UK is usually cited as good but, like their US counterpart, seldom go against Apple's outdated specs. See:

They show the max RAM for your model as 1GB--yesterday's news. However, if you order their offering for a G5 iMac, you get the larger modules. Here is a listing for a 2GB kit (2 x 1GB modules) of the right config:

Scripting WLC show commands (ie show client detail) every x seconds/minutes

Is there a simple way to script using either a terminal client (putty, teraterm, etc.) or Prime Infrastructure whereby I could set up a set of commands to be run at a certain interval?
I want to conduct some client testing roaming across a site whilst some how performing a show client detail every 15 seconds and a show run-config every 30 minutes?
TIA,

Is there a simple way to script using either a terminal client (putty, teraterm, etc.) or Prime Infrastructure whereby I could set up a set of commands to be run at a certain interval?
Yes you can.
The easiest method is to use console. You can knock up a script to run the command at specific intervals and log the outputs. If you do this, you must ensure the console timeout is expanded.
Another option is to create a PERL script (using KRON) to telnet/SSH into the appliance and run the command and retrieve the results.

TCP connection error when sending MODBUS commands to WAGO 750-881 controller after 113655 bytes of data have been sent

Hi all,
I am new to the world of labview and am attempting to build a VI which sends commands to a 750-881 WAGO controller at periodic intervals of 10ms.
To set each of the DO's of the WAGO at once I therefore attempt to send the Modbus fc15 command every 10ms using the standard Labview TCP write module.
When I run the VI it works for about a minute before I recieve an Error 56 message telling me the TCP connection has timed out. Thinking this strange, I decided to record the number of bytes sent via the TCP connection whilst running the program. In doing so I noticed that the connection broke after exactly 113655 Bytes of data had been sent each time.
Thinking that I may have been sending too many messages I increased the While-loop delay from 10ms to 20, 100 and 200 ms but the error remained. I also tried playing with the TCP connection timeout and the TCP write timeout but neither of these had any effect on the problem.
I cannot see why this error is occuring, as the program works perfectly up untill the 113655 Bytes mark.
I have attached a screenshot of the basic VI (simply showing a MODBUS command being sent every second) and of a more advanced VI (where I am able to control each DO of the WAGO manually by setting a frequency at which the DO should switch between ON and OFF).
If anybody has any ideas on where the problems lie, or what I could do to further debug the program this would be greatly appreciated.
Solved!
Go to Solution.

Hi ThiCop,
Yes the error occurs after exactly 113655 bytes every time. The timeout control I would like to use is 10ms, however even increasing this to 1s or 10s does not remove the error, which leads me to believe that this is not the issue (furthermore, not adding any delay to the while loop, thus letting it run at maximum speed, has shown that the TCP connection is able to send all 113655 bytes in under 3 seconds again pointing towards the timeout control not being the issue here).
I attempted Marco's suggestion but an having difficulty translating the string returned into a readable string, (rightnow the response given is " -# + ").
As to your second suggestion, I implemented something similar where I created a sub VI to build a TCP connection, send a message and then close the connection. I now build each message and then send the string to this subVI which successfully sends the command to my application. Whilst not being the most elegant method of solving the issue, it has resolved the timeout problem meaning I am able to send as many commands as I want. So in that sense the problem has been solved.
If you still have tips on how to correctly read the TCP read output, I would however like to see if I could not get my first program to work as it is slightly more robust in terms of timing.
Modbus TCP RTU is a binary protocol, as you show in your Basic VI, where you format the data stream using byte values. So you have to interprete the returned answer accordingly with the Modbus RTU spec in hand. Now what is most likely happening is that the connection gets hung after a while since you do NOT read the data the device sends as response to your commands. The TCP/IP stack buffers those bytes and at some point the internal buffers overflow and the connection is blocked by the stack. So adding the TCP Read at strategic places (usually after each write) is the proper solution for this. Is there any reason that you didn't use the NI provided Modbus TCP library?

Okay so my phone crashes approximately every 30 seconds. I have tried resetting it by DPU as well as on the phone itself. Once in awhile i get an error message about unknown error 1. If i look at the diagnosis or if runs on itunes i get the following. When I called the support at AT&T they think the phone is shot and it is a hardware thing but i have a hard time believing that when it happened when I sync'd it to my computer. It did get progressively worse though, at first it crashed not that often and then got worse. So restores are failing, recovery, everything. Anyone run into this?

I deleted my old email address and added a new one, after my iPhone died iCloud keeps popping up asking for the password of my old email address. I can't remember my password and the account is still gone, it pops up every few seconds. How can I fix this?

If you are unable to remember your password, security questions, don’t have access to your rescue address or are unable to reset your password for whatever reason, your only option is to contact AppleCare(or Apple ID Support), upon speaking to an operator you should explain that your problem is related to your Apple ID, this way you will not be charged for assistance, even if you don’t have an AppleCare plan.
The operator will take you through some steps you may have already tried, however they need to be sure they have exhausted all usual approaches before trying to reset your account, so you should try to be helpful and show patience with the procedure.
The operator will need to verify they are speaking to the account holder and may ask you some questions that only the account holder could know, and you will need to answer them if the process is to proceed.
Once the operator has verified your identity they will send a message through to your device which contains an alpha numeric code, which you will need to read back to them.
Once this has been completed they will send an email to your iCloud email address after a period of 24 hours, so you should check that mail is enabled in your devices iCloud settings.
Upon receipt of the email, use the reset link provided to reset your password, after which you should be able to make the adjustments to iCloud that you wish to do.
