Ambiguous Name of a PLCOpen FB instance

[ericvergara]

Hello,

I have been trying to command an axis via function blocks of the PLCOpen Library,

I have installed the SoftMotion Package 4.1.0 and I have the 1.14 version of the PLCOpen Library

The problem comes when I instance any function block of this library. If I generate the Code of the PLC Program it returns a " Ambiguous use of Name "MC_FB" " error. I have changed the name several times but it continues to return this error.

Does anyone know what should I do?

Thanks in advance,

Hi ericvergara,

seems like you have both libraries installed, CXA_PLCopen and SM3_Basic.

The CXA library requires our Motion App.

And you need to specify the whole namespace as the fb exists in 2 different libraries, see screenshot how to do it.

Additionally here is a link to a Softmotion Howto.
