Why does the error output of the MBP_MSTR block come on when the block is not enabled?



The MBP_MSTR block programmed in either Concept or Unity Pro will error if the CONTROL and DATABUF outputs are not located to 4X registers. The ERROR output may come on for a number of reasons, but the ERROR output on without the ENABLE input high indicates that the CONTROL and DATABUF outputs are not located.
