Maintain a VXI - 11 connection continues over TCP/IP to a device over a long period

Hello

Is there anyone managing to maintain a continuous connection of VXI - 11 from Matlab to a device connected using TCP/IP over a period of a few days to weeks? In the meantime, the unit could be handle quasi-continuite orders SCPI and send information back to Matlab very well also?

I use Matlab 7.40 with the instrument, NI-VISA 460 runtime control toolbox and Anritsu device with an Ethernet 10BASE-T interface. After about 24 hours of SCPI continues handling command, I get the error "VISA: the Protocol specified is not valid.

A solution is to send that an SCPI reset command to restart the device and try again. Network and power systems are very good; No, the problem here. If this isn't a known problem, the problem is maybe on the side of the unit.

All your comments/ideas would be very welcome

Thank you

You use DHCP or static IP address? Normal DHCP lease is renewed every 24 hours and who knows what that the instrument will during this period - reset the link perhaps!

  • How to make a transformation of Fourier data acquired over a long period?

    Hello

    I am trying to configure Labview such as my data will be collected during the 10ish minutes and then have it handle all data in a Fourier transformation.

  • Why the fan on my macbook pro continue to run at a fast pace for long periods?

    The MacBook Pro mid-2010

    OS X El Capitan, 10.11.3 version

    Processor: 2.4 GHz Intel Core 2 duo

    Memory: 4 GB 1067 MHz DDR3

    Graphics card: NVIDIA GeForce 320 M 256 MB

    163 GB available

    iWorks ' 09 has been upgraded to the latest versions

    No new upgrade is available for the system.

    My Question: Why the fan on my macbook pro continues to run at a fast pace for long periods?

    I guess that the fan runs constantly, because the CPU is working at a high rate. I rebooted several times but without any resolution systems. At the bottom of the computer is very hot at times so place the laptop on an object that allows good air circulation. This problem occurs intermittently every few weeks or more. I wonder if it is downloading an important upgrade, do a scan of viruses, or by working as a bot. Lights for hours. Currently, I estimate that it has worked rapidly to possible 6 hours. Thank you.

    It will usually be to dissipate internal heat from running resource intensive applications.

    Download and install a temperature/speed control application.

    Open the activity monitor all THE PROCESSES and CPU to display values between high and low.

    When the fan speeds up, post pictures of both for review.

  • How to test if the pc is connected to the TCP/IP protocol?

    Hey,.

    I was checking for error 66, I think that it check if the connection has been closed in order to reconnect

    do you not think that the error 56 or 60 are better?

    with respect,

    56 is the time-out. This will depend on your remote service if this should be considered as error or ignored. If it is a server application, it should certainly be able to respond within the time limit. But if your host application is the server and the remote application is the client it is very common to receive a time-out error when querying the client if it has new data to send.

    Order the examples mentioned previously, they really give you a good idea on how TCP/IP network communication must all work, even if there is still a lot to improve to create a truly reliable connection. But start from there come back if you get into trouble.

  • internet disconnection but to maintain the local network connections

    How disconnect (and subsequently reconnect) the internet connection of a computer in the network when you are keeping this computer completely connected to the local network.  I can't find a way to do it with a few simple clicks.  This is easily achievable with Network Magic, even the point of having a particular computer available in the annex "over and out" for internet and 100% available for the local network.  The problem is that Network Magic is no longer available.

    Solutions appreciated.

  • Questions of ESXi 5.1 ISCSI--> cannot establish a network connection (continued)

    Hello world

    I had a problem there not too long ago (thread link below) where my ESXi hosts could not establish a connection with an IBM DS3500 on start up and "rescan", however their connectivity worked correctly without any problem after commissioning and when a "rescan" finished. We determined that the most likely cause was the unit IBM itself. However, I wasn't completely satisfied.

    In order to deepen the question and dismiss my guests being the problem, I created a unit ISCSI myself with two new hosts of ESXi 5.1 (version 1157734).

    ESXi signals that it cannot connect to the initiator ISCSI (network error) - but it can run virtual machines and browse data stores?

    The configuration is the following:

    Test environment:

    2 x ESXi 1157734 hosts

    1 x server Freenas ISCSI (ZFS R10)

    At the start of my ESXi hosts in the test environment, download the same error as our production environment. They also put on the same error message (in the event log) when I "rescan" map of the ISCSI software. However, once the scan is finished, I can't see any error message and everything continues as it should (Round robin, active active). I can get a brilliant flow also. It's as if the errors are almost... false positives?

    Example of the error message (test environment):

    Connection to the iSCSI target

    IQN.2011 - 03.org.example.istgt:iscsi on vmhba35

    @ vmk2 has failed. The iSCSI initiator couldn't

    establish a network connection to the target.

    17/10/2013-08:33:35

    ESXi hosts are configured as follows:

    Test environment:

    • (ESXi hosts) Two network cards for ISCSI, one for VM traffic
      • NIC1: 10.20.20.2/24, NIC2: 10.30.30.2/24
    • (Freenas) Two network cards installed on the ISCSI device (dedicated to ISCSI traffic)
      • NIC1: 10.20.20.1/24, NIC2: 10.30.30.1/24
    • ESXi is set to round robin, which works properly (I can max on both ports at the same time)
    • Two VMKs are related to the ISCSI Software initiator and defined to dynamically discover the two ISCSI addresses
    • Unity of ISCSI and the hosts are not on the VLAN, the switch is dedicated to ISCSI traffic (However in the production, the two networks are separated by VLAN.) I removed the in the test environment to simplify everything)
    • The vSwitches (who hold a single VMK for ISCSI) are fixed:
      • "Promiscuous" mode: reject
      • Change of MAC address: accept
      • Forged passes: accept
      • The traffic shaping: disabled
      • No NIC teaming (obviously)
      • Each VMK inherits the settings of these

    Quick points:

    • My hosts use VMware approved NIC in my test environment. My production environment runs on full VMware hardware approved
    • Can I use ping of vmk join each each VMK ISCSI initiator
    • I can use the nc-z target_ip 3260 command to check connectivity to the port
    • The ISCSI test has two network adapters, each on 1 Gbps ports
      • I can get around 800mbps per port when copying lots of files (both ports are active)
      • I see no error in copying a large number of virtual machines around, or backup files
    • I only see errors on start up and "rescan".
    • I have two network adapters on each host ESXi dedicated for ISCSI. Each NETWORK card has a single VMK. A single mapped port on ISCSI, the other is mapped to port B (I used to have two VMKs by nic, but I removed that in order to simplify everything)
    • I have updated the firmware on our switch of production. No results
    • I've used 4 different switches in order to avoid a network problem. No results
    • I tested ESXi versions 5.0, 5.1 (799733 & 1157734), all have the same mistakes
    • The ISCSI ports are on different networks according to the VMware (I was told not to put on the same network VMKs)

    Any ideas? It's starting to drive me up the wall. Any help would be greatly appreciated

    I've seen several times in recent months and was beginning to think it is specific to the HP P2000 units because it's the only time wherever I saw him! I now believe that ESX/iSCSI rather than issues of driver or table.

    On my last install, I found that errors occur as soon as the table is connected, i.e. before any storage is displayed.

    Single host ESX, no guests. 2 Intel adapters to 2 HP past by dedicated HP P2000 1 GB table with all 8 wired ports.

    All roads are good, all lights are in the State expected.

    It did not affect the use of the storage in question to any site, so there has been no need / a momentum of any further investigation.

    B! 886y annoying however!
