TCP Time set VIs for FP-2000, LV 6.1, not working with LV 7.0.

[upchuckjunk]

I had patched together, with NI's help, some TCP time server, time update VIs for my FP-2000. The FP-2000 was keeping perfect time while running LV 6.0, RT 6.1 (I think). Now, running LV 7.0, RT 7.0, the FP-2000 will throw up an error 56 every time I run the TCP connect vi. The VI functions well on my PC and appears to be functional on the v6.1 unit. Why would the TCP connection vis not function on the v7.0 FP-2000?

Did you also change computers/operating systems? The following Knowledge Base talks about that error occuring with Windows XP. You need to disable the Internet Connection Firewall.

There is no hardware reason for why your TCP/IP functions are not currently working. Since this is an embedded application and that seems to download fine, we know your controller's connection to the Ethernet is fine.

Nope, didn't change operating systems.
I did have to completely reload the FP-2000 though.
Seems that the update function under Max doesn't
always do a clean install and it initially hosed up the FP-2000. I can send you my TCP Time vi w/settime.dll if that will help. Does RT have any known issues using TCP connections embedded?

If the error is coming from the TCP Open Connection in your VI then I suspect it has something to do with a firewall or your timeout settings (try using the default value). Try running a very simple VI that just opens up a connection on a well known port and see if you get an error message (port 80). TCP/IP is used very frequently embedded on FieldPoint and there are currently no known issues.

Great, I am checking with my IT folks to see if my units have the proper access through the firewall. Thanks for your help. BTW, the port 80 didn't work, neither does my port 13 on open. So ... I'll assume that the firewall has me blocked out somehow. I'll update this thread when I find out the firewall status.

Thanks again,
Bill

OK, here's the scoop.
It seems that one or more of the software apps. that reside on the FP-2000 were corrupted. I cleaned out my FP, reinstalled all the apps (less Visa, which I don't use) and now the unit appears to be talking up a storm on the net. So, thank your for your help and I'll be back if I need any other assistance.
