*1 : EM (Extended data memory) of C series is available only with C200HX/HG/HE (–Z).
*2 : Only current bank can be allocated for EM (Extended data memory).
Since the special auxiliary relays of the CVM1/CV series PCs are all allocated to
system functions, they cannot be used for purposes other than system use.
The range of each memory area differs according to the PC type. Refer to AP-
PENDIX L “PC Memory Map”, page 684.
If the data memory (DM) is designated, a bit number (00 to 15) must be specified
after the word number.

screen remains displayed even if the bit returns to “0” (OFF)).
