A maximum of 100 programs and up to 2,000 blocks in all programs total can
be saved. The automatic loading function is provided for additional programs
in order to support applications requiring more program capacity. This func-
tion allows more programs or program blocks to be executed by treating exter-
nal memory devices connected to a personal computer running CX-Motion as
MC Unit memory.
The automatic loading function is executed by the IOWR instruction for the
Command Area. Either Automatic Mode or Manual Mode can be used.
