Reference One allocation word of the memory table can use continuous areas of up to 2 words in the case of numeral memory table or 20 words in the case of character- string memory table.

Reference When allocating a memory table to words, the allocation must not exceed the word area.

Since the special auxiliary relays of the CV series PCs are allocated to thesystem, they cannot be used for purposes other than the system use. However, reading from them is possible.
