 Note that the text will be invisible when the message is pressed, if the color of
message display (color of bit memory table entry) and the background color in
reverse video of alarm list/history are the same.
The number of bit memory table entries can be set as one of the following at the
Support Tool.
• 256 (bit memory table entry numbers 0 to 255)
• 1000 (bit memory table entry numbers 0 to 999)
Since the bit memory table shares memory with the screen data, setting a large
number of bit memory table entries reduces the memory area available for
screen data.
