1. In order to associate shared variable with remote OPC server variable it is
4
necessary to select not the variable on the remote OPC, but the corespondent
5
local variable which is available trugh NI Variable Engine under appropriate
6
OPC connection to the server (should be created in advance).
7
2. NI Variable Engine is not fully functional OPC Server. Read request is not
8
implemented. However, subscriptions are working well and WinCC can use it.
9
3. To include Variable Engine in standalone application, the "Enable Enhanced
10
run-time DSC support" should be enabled in advanced options. However, it should
11
be include only to the applications really requiring it, and could cause
12
other applications to perform "Invalid Opreration and would be closed".
13
Starting from LabVIEW 8.2.1 it is not required (and causing crash) even for
14
applications working with Shared Variable Engine.
15
4. To include Web Services support, not only Dot.Net 1.1SP1 as required by
16
NI should be installed, but Dot.NET 2 as well.

1. The LabVIEW 8.2 contains a bug, crashing web services with output parameter.
22
The upgrade 8.2.1 is mandatory.
23
2. The LabVIEW 8.2.1 contains a bug, crashing LabVIEW on socket communications.

3. NI Internet toolkit 6.0.1 contains a bug preventing requesting HTTP documents
25
which are bellow 1KB in size. To overcome problems, just add extra spaces in the
