Why I see "Undefined function or variable 'opcuaserverinfo'." using OPC Toolbox in R2015b 32 Bit?

I try to use the OPC UA functions in MATLAB R2015b with 32 Bit, but it does not work and I see this error:

>> serverList = opcuaserverinfo('localhost')

Undefined function or variable 'opcuaserverinfo'.

Besides this, I checked the path:

>> cd d:\Program' Files (x86)'\MATLAB\R2015b\toolbox\opc\opc\

>> ls

>> which -all opcuaserverinfo

'opcuaserverinfo' not found.

Why is there no OPC UA function or is this caused by a bad installation?

Answer 1

[MathWorks Support Team]

The release notes of the R2015b release show the cause:

"Note: OPC UA support is available only for 64-bit Window operating systems."

As one can see, the reason is, the OPC UA functionalities are only shipped in the 64 Bit Windows version.
