We experience trouble with OPC connection between 32 ond 64 bit servers.
The thing is that the Ignition server is running 64bit OS (Win Server 2012 R2), and 64 bit java and 64 bit ignition 7.8 installed. On the other side we have 32 bit OPC server and 32 bit windows OS.
Everything works fine only if we connect to a 32 bit client with 32 bit ignition configuration.
But after the contract we must use 64 bit.
So that is what we have found about this problem
(NK-1300-0140 OPC Remote)
The installer now supports additional approved operating system versions including Windows 7 SP1 (64-bit) and Windows Server 2008 R2 SP1 (64-bit).
Note Even though OPC Remote can now be installed on 64-bit operating systems, the OPC Remote is a 32-bit application and is compatible only with 32-bit OPC clients.
The question is, has any one tested that type of connection.
So, I would appreciate, if somebody give me a hint.
