[Restrictions]
S
The number of bit memory tables can be set as one of the following at the Sup-
port Tool.
- 256 (bit memory table numbers 0 to 255)
- 1000 (bit memory table numbers 0 to 999)
Since the bit memory tables share memory area with the screen data, setting a
large number of bit memory tables reduces the memory area available for
screen data.
