Diconnection by iTools OPC server after 30 minutes ?

[alexphysiker]

Hi,

I have a problem with my program using OPC to talk to Eurotherm PID (2704, v6.30) controllers using the iTools OPC server (version 7.68). In the program the temperature is read/written by: DataSocket Write Double.viDataSocket Read Double.vi (for connecting I use: DataSocket Connect.vi )
When I start my program, exactly after 30 min the connection is disconnected (I think by iTools software, because I get a massage there: " Access to OPC functionality timed-out for client"" client forcefully disconnected. and LabView doesn’t  respond more (I have to end process by windows task manager).

Guys, I really need your help, because I have no idea what is wrong and my program should run as soon as possible.(I tried out all possible things, what I could do)  (Disconnect On Idle …, is not chooses) Do you have any idea about this problem ?Where this 30 min could came from?Is the reason for this error  iTools or my code  (or maybe LabView) ?!! 

If you want to see the program-code, I can upload it.

regards.... Alex

As say Owen.S here, do you have the licence?

Hello,

LabView -> yes, we have the licence (Heriot Watt University)

iTools OPC server -> no (but it can be used without the licence)

Not sure about the iTools licensing...

Contact directly Eurotherm to know if OPC Server is concerned by the 30 minutes restriction in evaluation mode too (as iTools Engineering Studio).

I can confirm that the iTools OPC Server will only operate for 30 minutes, with third-party OPC clients such as LabView, unless a Product Key is purchased from Eurotherm.

Why did you start a new thread?  It seems you got the answer in the other thread.  Either:

1.  Buy the license from Eurotherm for their OPC server.

2.  Go about it by another method such as using Modbus or reading the manual to see if there is another communication protocol that will work.
