Able to interact with a cRIO remote front panel from one computer but not another

I have a cRIO application that publishes a remote front panel for monitoring and control of the application. From one PC (Win7 & firefox) I can see, interact and control the cRIO through the published remote front panel. From a second PC, also Win7, I can see and monitor the cRIO's state, but the remote panel that is opened does not allow for any interaction and this is true whether I'm using IE, FF or Chrome as the browser. When either PC is connected to the cRIO, it is via a dedicated Ethernet link and only the cRIO and the one PC are on that network. For this two-device private network, the PC is always at address 192.168.1.1 while the cRIO always uses 192.168.84.199 (port 8000).
The firewall rules on both PCs are setup to allow all incoming and outgoing programs/ports/protocols to be used between these two IP addresses.
Both PC's have up-to-date LabVIEW development systems installed on them (which more or less guarantees they have the minimum require LV runtime needed to see and use a remote front panel).
What might be different on the PC that view but cannot interact with the remote panel?

Right click on the second one and select "take control of this VI".
As far as I am aware - only one viewer of the remote front panel can control the panel at any time - the rest can only view.
As I tried to say in my original post, there was only one host physically connected to the private network at any given time (by virtue of the fact that the one Ethernet cable connection to the private network was being moved back & forth between the two hosts) so there was no way both hosts could be trying to control the cRIO at the same time. I even went so far at one point of restarting the cRIO while it was connected to the problem host to see if would render it functional, but it did not.
But I did not know that it was possible to do what you suggested, much less that there was a right-click context menu associated with a remote panel, so I tried it and it worked! Thank you!

Problem with SMTP from one computer but not another

I have an iMac connected directly to my network via Ethernet and a MacBook Pro which connects via wireless. I have a program installed on my iMac that sends me alerts via e-mail, and it works just fine. When I try and use Mail, however, on my MBP with the exact same settings and credentials, it fails. To make this even more perplexing, Mail works fine from my office on a different network.
To work around this, I use Comcast's SMTP server on my laptop, but why would my regular e-mail provider's SMTP work on one machine and not another on the same network? The only difference is one is connected via Ethernet and the other by wireless.
I use a Time Capsule as my router and wireless access point. Has anyone got an idea about what's causing this?

Please report the relationship, if any, of the "regular e-mail provider's SMTP" and your ISP? If Comcast is your ISP, they regularly block use of Port 25, but if you have selected Use Default Port in Mail Preferences/Accounts/Account Information for the Outgoing Server, then it may be making the wrong choice to work with Comcast. Regardless of the ISP, for this regular account click on the arrows beside the name of the SMTP, choose Edit Server List, then click on the Advanced Tab that will then be seen and choose Use Custom Port, then enter the proper port directly -- that port is probably Port 587, but that could depend on the advisory of the email provider for using their SMTP.

Implicit read with assembly module instance working on one computer, but not another

Hi,
I'm trying to set up an on-site computer to run a VI which uses assembly instances for data communication, but for some reason I'm unable to establish a connection to the PLC.
I'm running the example vi "CreateAssemblyInstance.vi" to try and get the communication set up before I start using my actual program.
When I run this code on my development machine, I'm able to establish a connection to the PLC and read data. I then go into RSLogix 5000 and change the IP address to the on-site machine and try to run the test VI there, but I'm unable to make a connection. LabVIEW-side, the program thinks that it's established a connection and is reading/writing data, but PLC-side I'm getting a "Connection Failed" message in RSLogix.
I find it weird that LabVIEW thinks the connection was established just fine, which the RSLogix says it can't connect to the VI.
Just wondering if anyone else has had this happen. We aren't sure why the same VI runs on one machine but not another. We used RSLogix to change the IP address of the target machine, so we don't think that's the issue. And both computers are on the same network, so we don't think it's a firewall issue either.
LabVIEW-side, things should be identical. I'm running the same example VI that came with the Ethernet/IP module. PLC-side, we're changing the target IP of the module within RSLogix 5000 (and we're sending the updated information to the PLC) to match the machine we're trying to make a connection with. Are we missing any steps? This is the first time we've tried using an assembly module, so we're having a hard time troubleshooting.
Any ideas on why this is happening?

I'm pretty sure we're using a generic ethernet module:
I can communicate explicitly with the problem computer, it's able to use 'Tag Read' and 'Tag Write' to communicate with the PLC.
We started having another problem just recently too. The Tag Read and Write commands are almost always timing out. I keep getting the error message -251723752:
Detailed error info: Error -251723752 occurred at EthernetIP Tag Read REAL.vi;Details: The request response was not received in the requested timeout period Possible reason(s): Ethernet/IP Industrial Protocol: (Hex 0xF0FF0018) The request response was not received in the requested timeout period
I can't figure out what's causing this all of a sudden, could these issues be related?

Have had crashes with one computer but not another. one that crashes has adobe flash payer 15 active x installed. should I uninstall it

I have two dell computers - one with 7 and one with 8. have numerous crashes on 7 but not 8. noticed Adobe flash player 15 active x is installed on 7 but not 8. is this the problem. should I uninstall it?

It’s very sad, but many of the software down-loaders / installers will trick you
into installing not only their program, '''but other programs as well'''.
You have heard of the '''fine print in shady contracts''', right? Well, some
installers you need to look at the '''itsy bitsy teeny weeny fine print'''.
You are thinking you are giving the installer permission to install the program
you want by using the '''recommended''' option. But if you use the
'''Manual Option Instead''', you discover all kinds of stuff that
'''you do not even know what it is or what it does'''. From now on,
everyone needs to '''Use The Manual Option''' to put a stop to this.

I want to bcc myself when sending mail from one account but not another. When I check "automatically bcc myself", it bcc's me from both accounts. Can I set this to work with only one account?

I have two mail accounts on my Mac. I want one account to bcc me when I send emails from that account. I checked "automatically bcc myself" under mail>preferences>composing, but both accounts bcc me when sending mail. Can I set this to only bcc myself from one specific email account? Thanks.

It does not make sense that your ssh does not have a dash capital Y (-Y) option. It is in "man ssh", and my 10.6.6 has the -Y option, and I've had a -Y option since at least Tiger (10.4) days.
My ssh is in /usr/bin/ssh
I'm not very good at X11 issues, so I'm just throwing ideas out there.
Does your broken account have a $HOME/.ssh/config file, and if so, what is in it?
Does the broken account have any $HOME/.x* or $HOME/.X* files that X11 might be reading to configure your X11 behavior differently from the new test account?
$HOME/.Xauthority
$HOME/.Xdefaults-<hostname>
$HOME/.Xresources
$HOME/.ICEauthority
$HOME/.keymap.km
The above are a few names I found looking through "man X"
While I'm thinking about it, I assume that when going to the server, you are using the exact same user account on the server, so that you have a constant at least at that end.
Have you tried trashing your
$HOME/Library/Preferences/org.x.X11.plist
file, to see if that is affecting the broken account?
Again, I am just throwing out ideas to see if anything sticks.

How to programmatically load and show the front panel of a vi but NOT run it?

Is there a way to load and show the front panel of a vi but NOT run it? I am starting with the AsynchronousCallAndForget.vi from the example finder and inserted an invoke node with the FP Open method call prior to the Start Asynchronous Call node. The vi I am loading has the "Run when opened" unchecked and the menu bar IS visible so I can manually click the run arrow. Thanks!
Solved!
Go to Solution.

Why are you using the Async call? If you simply open the VI reference, then call the FP.Open method this works fine. You can then call the VI run method with Wait Until Done set to false if you wish to run it Asynchronously, this is how we did it in ye olde days before we had this new fangled "Start Asynchronous Call" stuff.

Add-on works with Firefox 33.0 on one computer but on another computer, Firefox 33.0 says that add-on is incompatible.

I have a laptop and a desktop computer. Both are HP and both have recently been updated with the latest version of Windows 8.1 and Firefox 33.0. On the desktop, Norton Toolbar still works fine. However, on the laptop, Norton Toolbar is disabled and the Add-Ons webpage has a message saying that Norton Toolbar is incompatible with Firefox 33.0. Why is it compatible on my desktop but not on my laptop?

hello, according to norton the toolbar is already compatible with firefox versions including the current release version. please run the norton liveupdate utility repeatedly & until all components are up-to-date. in addition make sure that the toolbar is enabled under ''firefox > addons > extension'' afterwards.

Home sharing works with one account but not another?

My family has an apple tv, we've been having problems setting up the home sharing and tried everything. We eventually decided to try my brother's apple id instead of my mother's and it worked. So my question is; why does home sharing not work with one id but works with the other? any suggestions to get it to work with my mother's id?

Try resetting the Apple TV. enter your mother's ID again. Then remove her ID on iTunes and re-add it. Then see if it works this time.

AppleTV v2 works with one TV but not another... ideas?

I just got a new TV (my girlfriend decided a 27" CRT TV was a bad idea, and got me a 24" Vizio LCD). I already had an AppleTV hooked up to the LCD TV in the living room (I share a house with two friends). It worked fine in the living room!
I decided to check things out, took the AppleTV into my bedroom with all the cords, attached it to the new TV, turned it all on... and the AppleTV started up, but was completely unresponsive to the remote. No flicker from the blue-light, nothing. I pulled the power cord, counted twenty seconds, plugged back in... nothing. Still no response to the remote.
Hit the menu and down-arrow, waited ten seconds, the blue-light flickered, I released and it restarted... to give me nothing. Still no other response to the remote.
Turned off the TV, disconnected the HDMI cord, waited about ten seconds, reconnected the cable and turned on the TV... nothing.
Took the ATV, with the same power cord and HDMI cable, reconnected to the older TV that it was attached to... no problem! Just fine!
Any ideas? I may consider getting a second ATV for my bedroom, but if there's going to be weirdness like this I may not do it.
I couldn't check any of the AppleTV's settings on the new TV, due to the lack of any kind of working connection, so I don't know what it was coming up as.

Connection issues with one computer - but not any other computer or iphone

I have a strange problem…. well, really it is my friends/co-workers problem, but I am his sponsor so I feel I need to be there for him.
We are both school teachers - and to help us in the eduction of our students we have created a wireless network (hidden so we don’t get caught!) that we can use in our area of the building. We have had it for several years and we have both hooked up to it regularly using our laptops and our ipod touch/iphone. Just recently my co-workers computer stopped being able to access the internet through the airport. We checked the settings, threw out the settings and re-entered them. Turned off the airport, turned it back on - typed in the network settings, connected - but no internet. We ran disk utility and repaired disk permissions. We have even gone as far as to create a new user…. still no luck. I have shut down and restarted the airport at school, still the issue remains.
He can see the shared disk attached to the airport, he sees my itunes library, I see his - and the rest of the teachers in the school see both of ours (we are music teachers, so our libraries are rather extensive!) and are constantly listening to our shared libraries. We know he is connected to the network, he just cannot access the internet. However, when he plugs in to the network (same settings) via ethernet - there is no problem he gets right into the network.
We both have airports at home - and we both have no problems connecting at home.
There are only two things that have happened since we noticed this problem… 1) is Snow Leopard - we believe the problem started AFTER that upgrade. and 2) we just got a new iMac Lab (I am teaching a new class - Audio Engineering this year) and in the lab I put a legal Airport - but that one IS NOT connected to the school network at all - it just allows all of the iMacs to access the shared hard drive (easier than running cable). This airport (new one - two channel) sits between his office and the old airport (single channel) that we use to access the internet and school network. I don’t think this is the problem as I have turned off the “new” airport and the problem remains.
Any ideas or suggestions would be greatly appreciated!!

Video works with one friend but not another?? please HELP!

my ichat video isn't connecting with my friend christina. we've taken turns calling each other and my computer keeps saying "no data has been received in 10 seconds" i can hear the ringing and then when we go to connect thats when the message comes up and cancels the call. at the same exact time my other friend sam was online so to test out my video chat i called her. & it worked. christina also connected with sam separately & that worked. then we tried a conference where all 3 of us could chat, and sam started it and invited both of us. it worked and we could all talk & see each other. however for some reason i can't connect to just christina. what's going on?

Hi,
Welcome to the  Discussions
iChat can have several messages on a failed chat.
The "No Data for 10 Secs" one only appears on chats that connect (even if you don't see the Video)
Basically it point to an issues between iChat at the Internet.
The same Result can be achieved by pulling the Ethernet cable out or turning the Airport card off or powering down the modem or router.
So we have to look at what can produce a similar break in the Internet connection without the drastic steps above.
Some modem and router have "protection" features that will do this.
Denial of Service (DoS) tries to make sure any data that come to your Computer does so at a rate it can handle.
It was originally designed to protect Web Servers from "attacks" where too many requests coming to frequently used to bring servers and their Internet connections to halt.
So Dos is threshold based,. It will cut any port that it thinks there is an "Attack" on.
Video chats can send lots of data.
These thresholds that are preset in the device tend to be set at Web page streaming speeds (allowing for multiple requests on popular servers) - but also at older Internet Speeds.
Modern Speeds and things like iChat Streaming two way Video can mean that certain Buddies can send you data faster than the threshold is set for particularly with iChat 5.
Stateful Packet Inspection (SPI) works differently but can only process a certain amount of data and will cut the port that is causing it to be overloaded making it Threshold based as well.
There is no way to change the thresholds involved so the best course of action is to Disable the feature.
So the Speed Sam has to send you Video may be lower than that of Christine and not bump into the threshold.
If Sam is the Host then it the Speed of that Internet Connection that governs how fast Data is sent to you.
One solution is to cap iChat in iChat > Preferences > Audio/Video Menu to 500kbps on the all Buddies involved.
If this solve the issue between you and Christine then you can move on to your Modem or router.

I am able to access home sharing on one computer but not the other

Both computers have updated versions of iTunes. I am able to access my brother's iTunes, which is on hard wire as well as mine, but I am unable to access my mom's laptop which is on the Wi-Fi. Does that make a difference for they are all part of the same network. I am able to see her home share on the left bar, but it just loads for a while then disappears. Also, she is able to access my home sharing from her laptop which just baffles me even more.

Power cycle the router and try 192.168.1.1 instead.

Can signon with one account but not another one

Been using iChat for years, the other day I installed both Adium and Fire but neither of them would signon my main AIM account but would signon my secondary AIM account. NOW, though, iChat refuses to signon my primary AIM account either! The only way to signon with that account is to use the AOL IM application, it signs on flawlessly. Password IS correctly entered, just the one AIM account won't authenticate.
I deleted iChat prefs, ran Cocktail, turned off the firewall, still no joy.
Ideas?

Hi ClarkDV,
In iChat prefernces > Accounts section
Is the tick box to Allow Multiple logins of the account name actually ticked ?
Do Adium and Fire have similar settings ?

Syncing iPhone with one Mac but not another

I have a home Mac and a work Mac.
I want the iPhone 3GS to sync with my home Mac, and it does so perfectly.
Sometimes I'm at work and I need to charge the phone, so I plug it into the work Mac, and it launches iTunes and attempts to sync with it (which, if I let it continue, would erase all my loaded stuff). I always stop it manually.
I see the option in iTunes checked for "Always sync the iPhone to this Mac" (or something like that). If I uncheck it, it fixes this, but next time I go home, the iPhone doesn't sync with the home phone because this option unchecks itself at home too!
So how do I make sure it syncs to the home Mac, but does not erase itself when plugged into the work Mac?

From the user guide, page 16, http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf
You may want to prevent iPhone from syncing automatically when you connect iPhone to a computer other than the one you usually sync with.
1. Turn off automatic syncing for iPhone: Connect iPhone to your computer. In iTunes, select iPhone in the sidebar, then click the Summary tab. Deselect “Automatically sync when this iPhone is connected.” You can always sync by clicking the Sync button.
2. Prevent automatic syncing for all iPhones and iPods: In iTunes choose iTunes > Preferences (on a Mac) or Edit > Preferences (on a PC), click Devices, and select “Disable automatic syncing for all iPhones and iPods. If this checkbox is selected, iPhone won’t sync automatically, even if “Automatically sync when this iPhone is connected” is selected in the Summary pane.
3. Prevent automatic syncing one time, without changing settings: Open iTunes. Then, as you connect iPhone to your computer, press and hold Command-Option (on a Mac) or Shift-Control (on a PC) until you see iPhone appear in the sidebar."
I use option 3 without any problems.
