Screen memory capacity varies according to which Screen Data Memory
Board is installed. The screen memory capacity, in turn, determines the num-
ber of screens that can be registered. Use the table below as a guide to se-
lect the amount of memory suitable for your needs.
Screen memory capacity Number of registered screens
32K bytes Mostly messages: 40 screens
Mostly graphics: 15 screens
64K bytes Mostly messages: 120 screens
Mostly graphics: 40 screens
128K bytes Mostly messages: 250 screens
Mostly graphics: 100 screens
256K bytes Mostly messages: 600 screens
Mostly graphics: 200 screens
Note The table above is strictly a guide. If the messages or other display data per
screen increase, the number of screens that can be registered will decrease.
Likewise, if the messages decrease, the number of screens that can be reg-
istered will increase.
