Accessing CAN-Device using CANopen

Hi all
Today I started with the initial startup of a CAN system, which should be used in a test rig.
First some information about the system:
- 3 external nodes connected to the bus (using CANopen protocol (at least I was told so), usually running autonomously)
- 1 CAN interface card (NI PCI-CAN Series 2)
- PC-System running under WinXP professional
I know the cabling works, as this was tested with another software.
The first thing I made a few weeks ago, was to download some source from the forums. Looking at this, I created a simple vi, which should get data using SDO (attached).
I also attached some pictures of this other software (screenshot software, screenshot can-trace). I just tried to do the same (read a value), with the above mentioned vi. There is also a screenshot from this vi, when I executed it. First it seemed ok, but then I got a warning (probe 1) out of CWrite.vi and right afterwards I got an error (probe 2) out of CWait.
At another try I came out of CAN init.vi with a warning, but then I got an error "unknown object" when trying to write the data.
Could you give me some advice on that? The values I tried to send are the default values of the vi.

Hallo Dirk
Ich switche jetzt auf Deutsch, nachdem ich in deinem Beispiel-Code einen Kommentar auf Deutsch gesehen habe.
War heute wieder an diesem Prüfstand und habe dein Programm mal laufen gelassen und dabei folgendes Verhalten gehabt:
1. Kein Problem bis zur Funktion "ncWriteObj.vi" - dort wurde eine Warnung zurück geliefert.
2. In der Funktion "ncReadNetMult.vi" wurde dann ein Fehler (siehe Attachment) ausgelöst.
Leider macht diese Fehlermeldung irgendwie nicht so wirklich Sinn, da die Busteilnehmer mit Spannung versorgt sind. Die ganze Verkabelung wurde, wie vorher schon mal erwähnt, mit einem anderen Programm (ext. SW) und dem Notebook eines Kollegen getestet. Dieser Kommuniziert über eine Softing CANUsb-Schnittstelle mit den CAN-Devices - ohne Probleme und mit der selben Prüfstandeinstellung wie ich das Versuche. Der Bus ist in den Geräten 2x mit 120Ohm abgeschlossen - also müsste auch das passen.
Ebenfalls angehängt habe ich dein Programm, so wie ich es getestet habe.
Für weitere Tipps und Infos bin ich sehr dankbar. Ich werde in den nächsten Tagen auch mal versuchen über diese Softing Schnittstelle zu kommunizieren. Trotzdem ist mein Schlussziel immer noch die Verwendung der NI-Karte.
Danke für deine Bemühungen.

HT204074 I have just changed my iPad mini password a day ago when trying to log on today it worked fine until about 4:30 (GMT) when I could not access the device using the correct password. I am absoloutley 100% sure it's correct. Any help?

I have just changed my iPad mini password a day ago, and when trying to access it today it worked fine until about 4:30 (GMT) when I could not access the device using the correct password. I am absoloutley 100% sure it's correct.Additional details:I was last using Kik messenger before it stopped working.I was sitting less than two foot away from the PS3 my brother was playing.I'm 14 but I'm not some spoilt kid who gets iPhones and iPads from his parents to mess around with, I have got important coursework and homeworks on there.Any help would be great Thanks.

Hello ConfusedLlama
If the password is not working to get into your iPad mini, you would need to follow the steps to restore it. If you have a back up through iCloud or through iTunes, you can restore from that back up and it would not bring back the passcode unless it is encrypted.
iOS: Forgotten passcode or device disabled after entering wrong passcode

Howto build CAN-devices with CANopen Library

Hi
We're two students working on a project to simulate CAN devices connected to a master. We have to "build" these devices in LabView. We've been working with the CANopen Library and the Channel API.
We would prefer to use the CANopen Library, because it is easier that way to build the device's behaviour as it would be in "real-life". But the problem is, that the CANopen Library has been developed to build a CAN Master. Is there a way to bypass that. So that we could build the other side... a CAN device.
We figured out, that we simply could alter the COB-IDs for de PDOs, that would do it. But the whole SDO and Sync part isn't that easy to bypass.
Would be glad if we could get a tipp
Thank you in advance

Hi,
I'm a little confused on the master/slave terminology you're using, however, as CAN (also Canopen) is really a peer bus. Any device on the CAN bus can transmit and receive messages as described below (from the NI-CAN User Manual):
"When a CAN device transmits data onto the network, an identifier that is unique throughout the network precedes the data. The identifier defines not only the content of the data, but also the priority. A CAN identifier, along with its associated data, is often referred to as a CAN Object. When a device transmits a message onto the CAN network, all other devices on the network receive that message
. Each receiving device
performs an acceptance test on the identifier to determine if the message is relevant to it. If the received identifier is not relevant to the device (such
as RPM received by an air conditioning controller), the device ignores the message.
When more than one CAN device transmits a message simultaneously, the identifier is used as a priority to determine which device gains access to the network. The lower the numerical value of the identifier, the higher its priority."
As you can see, you can use our CAN interface "slave" to receive commands from any other device on the CAN bus "master".
Also the Canopen Library is just the API for LabVIEW, both CAN and Canopen ends up in Bits which then will be send to the "Listeners"! They´re just on other Layers on the Programming. But both is really easy with LabVIEW
Hope this helps.

Figuring out how to access a device using Windows.Devices.HumanInterfaceDevice?

Before I start, I would like to share this link I used to access windows RT libraries from Desktop applications (only the ones stated in MSDN documentation that are accessible from desktop applications):
http://blogs.msdn.com/b/cdndevs/archive/2013/10/02/using-windows-8-winrt-apis-in-net-desktop-applications.aspx .
After following the above instructions you can import some of the windows RT libraries in references. I have been trying to use the Windows.Devices.HumanInterfaceDevice library. I think my UsagePage and UsageId are off though. I am wondering
if someone good in hex can translate them from my report descriptor. I already have the VID and PID (this should be enough along with the path if I called write file or some of the other win32/OS api's). Here's the code I am using in VB.NET:

Accessing peripheral devices using NetWeaver Mobile 7.1 application

Hi,
I'm developing an occasionally connected application for handheld devices using NetWeaver Mobile 7.1. From my application how can I access other peripheral devices (for example: WebCam) to capture the pictures.
Suggest me the ways to access the peripheral devices (WebCam) from my NetWeaver Mobile application.
Thanks in advance.
Regards,
DVR.

Hi Vinodh,
Please refer to SAP Note: 1057759 for getting the list of peripheral input/output device drivers supported in SAP Netweaver Mobile 7.1
You can also go through the help portal link on how to use peripheral devices in mobile application.
http://help.sap.com/saphelp_nwmobile71/helpdata/en/8F/0B674240449C60E10000000A1550B0/frameset.htm
In case you want to use another peripheral device like Webcam not supported, then you will have to take care of this in the application code itself. You can use JNI etc to talk to drivers like in a normal java application.

Nipun

Help needed restricting users admin access to devices using ACS 4.2

I have users that access the network via a VPN client to a PIX 515 which authenticates to the ACS (using the default group for unknown users) which uses an external Active Directory Database.
The problem I have is that as the ACS authenticates these users, it now allows them admin access to the PIX. How do I restrict access? I have looked at NARs using the 'All AAA clients, *, *' approach but that just stops their VPN access. ( I have a separate group called 'PIX ACCESS' which will contained only defined users for admin access).
Incidentally I have other devices on the network which are AAA clients, in particular Nortel switches. I can set the group settings for that RADIUS set up to 'Authenticate Only' (RADIUS Nortel option) and that works fine, I was expecting the ACS to have a similar setting for TACACS+.
So how do I allow the unknown users to authenticate to their AD database but restrict them admin access to the AAA clients?

Very common problem. I've solved it twice over the last 6 years with ACS. I'm sketchy on the details. But here goes. First option to explore is using RADIUS for VPN access, then TACACS on all the Cisco switches and PIX firewall. That would make it alot easier. I think that with TACACS, you can build a NAR based on TCP port number instead of IP address....
http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_tech_note09186a0080858d3c.shtml
So you'd have a group with 3-4 Administrators that can access PIX CLI, and another group of VPN users that can't access the PIX but can VPN in. So on the VPN group, put a NAR that restricts access to SSH/Telnet TCP ports?
This comes up everytime I install an ACS server, (every 2-3 years), and it's always a trick.
Please let me know if this works for you. And if it doesn't, let us know how you fixed it. I think I can get back into the ACS I last did this with and take a look, but I'd have to call up and make a special trip.

Controlling Access to devices using ACS

I am using ACS 3.2 and on the NAR section,I have used a wildcard (*) to define all the network devices on my network.All my users are in one group. However,I have just realised there is the need for me to create another group and put some users in that group so they only have access to some routers and switches and not all as define by the wildcard.
How do I achieve this goal.?

Under NAR select the Per Group Defined Network Access Restrictions.
Select the AAA clients you want the group to access.
Use the wildcard mask in the port and the address field.
You can also group the devices which you want to give access under a seperate NDG and in the NAR give permission to only this NDG for the group. In this way you may need not add individual AAA clients

HT1766 Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

You can store them on a separate hard drive, you don't need to keep them on your laptop's hard drive. On your computer's iTunes on the Advanced tab in Edit > Preferences there is a 'copy files to iTunes media file when adding to library' tickbox - if you untick that, you should be able to copy the films to a separate drive and add them back to your iTunes library (File > Add To Library) and it should then point to them on that separate drive and not copy them to your hard drive. When you are happy that it is what is happening and that they are safely on your external drive you can delete the films from your laptop's hard drive.
If you plug the external drive into a different USB port next time (assuming that your laptop has more than one) then it might get a different drive letter, so you might need to always use it with the same port.

Can I use the Airport Express to connect to a Linksys Wireless Network and then use the Ethernet port on the Airport for a wired connection to a device for internet access? Would I be able to then also use that Ethernet pt to a Ntwk Hub for more wired c

Thanks for the help. Looked but not clear on what I am trying to do as being possible. Can I use an Airport Express to connect wireless to a Linksys Wireless Router, such that I can then use the Ethernet ports on the Airport to either connected to a PC wired, or even use a hub off the Airport Express to allow multiple wired connections to it?
I am not looking to have the Airport Express extend my wireless network, just connect to it and provide me wired connections in a different location from where my Linksys Route is located. Would prefer to replace Linksys with all Apple, but just not possible financially yet. Thanks for the help.

If the AirPort Express Base Station (AX) is an 802.11n model, then yes, you can reconfigure it as a wireless Ethernet bridge. In this configuration, the AX would join the wireless network provided by the Linksys router and its Ethernet port would be enabled for either a single wired device or for an Ethernet hub or switch for multiple devices.

How can I use Airport Express to create a standalone Wi-Fi network without Internet Access so I can browse web pages on the local network? I will be using MAMP as my server (Apache)

I would like to create my own Wi-Fi standalone network at an upcoming tradeshow where there will be NO internet access.
Currently, I run and develop sites on my iMac use MAMP to manage my sites locally. Using MAMP, I run my sites as though they are on the internet although everything is local.
I purchased an Airport Express hoping I could create a standalone network so that the iMac would broadcast its website to whatever device connects to it such as my iPhone, iPad and MacBookPro.
However, after setting up the network successfully (I have a green light on the Airport Express, and there is NO internet going through it), I am not able to go any further by logging into the iMac's websites from the other machines. Form my MacBookPro Finder, I can look at files and folders using afp://10.0.1.2, from the Find/Go/Connect to Server utility, but I can't browse the website that is running on the iMac via the Safari browser.
Can anyone help me configure my MacBookPro (or iPad, or iPhone) to run the website on the iMac when they are all on the same network?
Thanks so much!!

1) connecting the TC using a ethernet cable from one of the two modem's LAN ports to the TC's WAN port
2) create a new Wi-Fi network using the TC ?
Does someone already create a new Wi-Fi network using its TC connected by Ethernet on a modem/router device ? How do you set up the DHCP (and NAT) ? Which range did you use ?
This is easy enough to do..
Plug the TC directly into a computer.. without other connections to do the setup.
Using the newly installed 5.6 utility.
Bridge the TC.
Create a wireless network.
This is an older screen shot and I would set security to WPA2 Personal only not WPA/WPA2 Personal as shown above.
I do recommend you use wireless names that are short, no spaces, pure alphanumeric.
Update the TC..
Now plug it into the modem router.. it will be a part of the network without doing NAT and DHCP itself.. which you do not want.. that leads to double NAT issues.. but it is a WAP that provides access to devices on both 2.4ghz and 5ghz bands directly to the main router.

Can i use same address pool for different remote access VPN tunnel groups and policy

Hi all,
i want to create a different remote access VPN profile in ASA. ihave one RA vpn already configured for some purpose.
can i use the same ip address pool used for the existing one for the new tunnel-group (to avoid add rotuing on internal devices for new pool) and its a temporary requirement)
thanks in advance
Shnail

Can multiple Virtual Devices use the same IVI Driver Sessions?

I am using Switch Executive 2.0 and I'm having problems creating multiple Virtual Devices.
I have created a virtual device on a development computer that has no hardware connected to it. This virtual device uses specific drivers to simulate the devices. The problem I'm having is that when I create a second virtual device and try to add the same IVI Switches as the first Virtual device, I'm getting the following error:
An error has occurred while attempting to access the device deviceA_ivi.
Error -223116 occurred:
Internal Software error occurred in Switches software. Please contact National Instruments Support.
File name: .\source\mxsWrappers\tMXSObject.cpp
Line Number 192:
Status Code: -223116
Can someone please explain why?

Can you please elaborate on how did you create those simulated devices? Namely, what does your IVI configuration look like? What does the driver session for the logical name look like? What's the software module? What's the hardware module? What is the driver setup string, and what is the simulation mode for the device in question?

A family member recently downloaded an iBook on my device using their apple I'd. Now I don't have access to the material I've purchased using my apple I'd for 90 days! So frustrated! Any tips?

A family member recently downloaded an iBook on my device using their apple I'd. Now I don't have access to the material I've purchased using my apple I'd for 90 days! So frustrated! Any tips? ITunes won't allow me to download the books I've paid for!!

That wasn't something that I was aware of, but looking at this http://support.apple.com/kb/HT4627 I'm not sure that there is much you can do about the device itself. I'm also not sure whether it only affects downloading directly on the device itself or whether you can connect the iPad to your computer and sync content across to it from your account that way - or even whether restoring back to factory defaults on the iPad will bypass the 90 days

Can't use Find My Friends on iPhone due to Apple ID not being verified. Can't do this as I can't access my .mac email any longer and I can not change the primary e-mail address for my Apple ID!

Can't use Find My Friends on iPhone due to Apple ID not being verified.
Can't do this as I can't access my .mac email any longer and I can not change the primary e-mail address for my Apple ID!
So my options are:
Create a new Apple ID, use that and lose all the apps I've purhcased with it (a fairly substantial amount)
Somehow Migrate these purchases over to a new Apple ID
Apple let me change the primary ID for the account
Anyone else ran into this before?
I've tried accessing the mail through a mail application using the correct server information, and trying both the old 6 character password and the one I had to change it too after they updated the security guidelines - neither work.
Help would be greatly appreciated as I can see more services down the line not working without the address being verified!

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. When you do this you may find that the password for your old ID isn't accepted. If this should happen, and if your old ID is an earlier version of your current ID, you need to temporarily recreate your old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You should not need to verify the old email address. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Can I use one email address for two apple devices? (One iPad2 and one iMac.)

I've been trying to find this information by searching the web and I can't find a good answer.
Can I use [email protected] for my "iPad AppleID" and use the same email address for my "iMac AppleID"?

your mail account has nothing to do with your apple id or device or even platform
you activate your mail account in your mail-app on your device, just pay attention you activate your account as IMAP and not as POP or Exchange
I suppose Verizon.net offers IMAP too?
citation from Wikipedia :
IMAP supports both on-line and off-line modes of operation. E-mail clients using IMAP generally leave messages on the server until the user explicitly deletes them. This and other characteristics of IMAP operation allow multiple clients to manage the same mailbox. Most e-mail clients support IMAP in addition to Post Office Protocol (POP) to retrieve messages; however, fewer e-mail services support IMAP. IMAP offers access to the mail storage. Clients may store local copies of the messages, but these are considered to be a temporary cache.
