PT) to the PC memory.
2. Register the memory table entries for the numerals and character strings to
be displayed when creating the screen data by using the NT-series Support
Tool.
To display a character string, use a character display and specify the charac-
ter string memory table entry by using the NT-series Support Tool.
To display numerals, use a numeral display and specify the numeral memory
table entry by using the NT-series Support Tool.
3. Set the copy source data to the memory table entry when creating the screen
data by using the NT-series Support Tool.
Use the table edit function.
4. Program the PC to write the copy type, copy destination memory table entry
number, and copy source memory table entry number to the copy memory
table entry setting word in the PT Status Control Area.
S Order for writing to the PT Status Control Area (PC to PT)
First write the copy destination memory table entry number, and then, write the
copy source memory table entry number to the PT Status Control Area (PC to
PT).
The NT30/30C reads the area sometimes when the PC is writing the settings. If
the copy source memory table entry number has been written first and is
changed, unexpected memory table entry may possibly be changed.
S Allocated Words that the NT30/30C Reads
The NT30/30C reads the allocated words in the PC for the memory table en-
tries that need to be displayed. If the copy source memory table entry is allo-
cated to a PC word, it may sometimes be used at the initialization only.
S Use of the Copy Type
Copy will not be executed when the copy type is other than 0 or 1. The memory
table entry copy is executed only when the contents of the area are changed.
