Chapter 5 - Initializing the GP
When these five items, "Current Screen Number", "Error Status", "Clock Data
(Current)", "Change Screen Number", and "Display ON/Off", have been selected,
word addresses are assigned to each item, in order, as shown here.
The Device Address set up for the SET UP OPERATION SURROUNDINGS
screen's System Data Start Device/Start Address is "+0".
For example, if the System Area Start Address is D00200, and the Change Screen
Number is designated, since the Change Screen No's address is +6, its word
address will be D00200+6=D00206. For System Data Start Device and Start
Address settings, refer to 5.5.1 SET UP OPERATION SURROUNDINGS (1:1/
