Note 1: Out of check-marked modes in the "Allocation modes" column, only one mode can be selected.
Note 2: Up to two I/O extension boards can be mounted on the controller. There are no restrictions on the choice of
extension slots or the mounting order.
Note 3: When two I/O extension boards are mounted, the controller recognizes the one inserted in the left-hand
extension slot as Extension 1. The allocation I/O port numbers on Extension 1 and 2 boards differ with each other.
