2-2SectionAreas for Control/Notification

Reference:  The screen number is notified only when the screen is switched by operation

at the PT.

 When overlapping screens are displayed, the screen number of the parent

screen is notified.

 When the PT is set to NT20S or NT30/620 compatible mode, the screen switch

setting notification from the PT occurs in the first word (word m) of the PT status

notify area. Refer to Appendix C for details on the NT20S and NT30/620 com-

patible modes.

Copy Source/Copy Destination Memory Table Entry Numbers

Designate the memory table entry numbers of the copy source and copy des-

tination memory table entries as 4-digit BCD or hexadecimal values, when copy-

ing data between memory table entries in the PT. Whether the values are BCD or

hexadecimal is determined by the setting for numeral storage type in the PT con-

figuration settings made with the Support Tool.

The memory table entry numbers that can be designated are indicated in the

table below.

BCD Hexadecimal Numbers

0001 to 1999 0000 to 07CF Memory table entry numbers 0 to 1,999

Note that it is only possible to copy between the following combinations.

• A numeral memory table entry and a numeral memory table entry

• A character string memory table entry and a character string memory table

entry

Reference:  What is designated here is the memory table entry number only. The type of

memory table (numeral/character string) is set by the memory table copy type

bit in the PT status control bits.

 Copying is not executed just be writing the memory table entry numbers. It is

executed when the memory table entry copy execution bit in the PT status con-

trol bits is turned ON.

 Since the memory table entry numbers start from 0, if there are 2000 memory

table entries, the range is 0 to 1999, and if there are 1000, the range is 0 to 999.

 When the PT is set to NT20S or NT30/620 compatible mode, copying between

memory table entries is performed differently. Refer to Appendix C for details

on the NT20S and NT30/620 compatible modes.
