Functions in Individual Allocation Modes

Functions of I/O signals differ depending on the allocation modes, as shown in the table below.

Allocation mode	General description
Mini I/O dedicated	Combination of bits commands operations. Some functions are deleted from the ones provided in Standard allocation. Mini I/O system allocation is allocated to the Mini I/O area. When an I/O option board is attached, only the user signal is allocated to the I/O option board area.
RC3 compatible	Functions, such as program activation, are specified by each bit. Operations are directed by the bit being set. "Compatible" system allocation is allocated to the I/O extension board area. Only the user signal (excluding CPU Normal) is allocated to all ports of the Mini I/O area.
Standard	Directs program activation, etc. with a combination of bits (I/O command.) This allocation has the greatest number of functions. "Standard" system allocation is allocated to the I/O extension board area. Only the user signal (excluding CPU Normal) is allocated to all ports of the Mini I/O area.
All user I/O	Only the user signal is allocated to the I/O extension board area. Only the user signal (excluding CPU Normal) is allocated to all ports of the Mini I/O area.
