Reference:
S
The screen number is notified only when the screen is switched by operation
at the PT.
S
When an overlapping screen is displayed, the screen number of the parent
screen is notified.
S
When the PT is set to 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 NT30/620 compatible mode.
Copy Source/Copy Destination Memory Table Numbers
Designate the memory table numbers of the copy source and copy destination
memory tables as 4-digit BCD or hexadecimal values, when copying data be-
tween memory tables in the PT. Whether the values are BCD or hexadecimal is
determined by the setting for numeral storage type in the PT configuration set-
tings made with the Support Tool.
The memory table numbers that can be designated are indicated in the table be-
low.
BCD Hexadecimal Numbers
0001 to 1999 0000 to 07CF Memory table numbers 0 to 1,999
Note that it is only possible to copy between the following combinations.
•
A numeral memory table and a numeral memory table
•
A character string memory table and a character string memory table
Reference:
S
What is designated here is the memory table 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.
S
Copying is not executed just be writing the memory table numbers. It is
executed when the memory table copy execution bit in the PT status control
bits is turned ON.
S
Since the memory table numbers start from 0, if there are 2000 memory tables,
the range is 0 to 1999, and if there are 1000, the range is 0 to 999.
S
When the PT is set to NT30/620 compatible mode, copying between memory
tables is performed differently. Refer to
Appendix C for details on the NT30/620
compatible mode.
