NOTE: When using the Matrix mode, smaller matrices are supported.
The C2N-IIF can support a maximum of four rows and four columns.
When using smaller matrices (i.e. 4x3, 3x3), each row and column of the
matrix output must be matched to the corresponding port on the C2N-IIF.
Do not connect a column output to a row input.
For information on selecting the C2N-IIF’s operating mode, refer to
“C2N-IIF Symbol in Programming Manager” on page 27.
