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

1 回表示 (過去 30 日間)
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
+opc          flatnamespace.m    opcqid.m        opcsupport.m

>> which -all opcuaserverinfo
'opcuaserverinfo' not found.
Why is there no OPC UA function or is this caused by a bad installation?

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.
