Operate the PT status control area in the manner shown below to copy data be-
tween memory tables.
1, 2, 3...
1. Write the memory table numbers in the PT status control area as indicated
below in either 4-digit BCD or 4-digit hexadecimal. Which of the BCD and
hexadecimal notations is used is determined by the setting for PT Configu-
ration – Storage Type made at the Support Tool.
• 2nd word from the beginning (word n + 1)
0000 to 1999: Copy source memory table No. (0 to 1999)
• 3rd word from the beginning (word n + 2)
0000 to 1999: Copy destination memory table No. (0 to 1999)
Reference: The range of numeral/character string memory table numbers which can actually
be used depends on the number of numeral memory tables and the character
string tables set in PT Configuration – System setting at the Support Tool.
2. Set bit 2 of the 4th word (word n + 3) from the beginning of the PT status
control area as indicated below to match the type of memory table for which
copying is to be executed.
Memory table type: Bit 2
• Character string memory table: 0 (OFF)
• Numeral memory table:
3. Set 1 (ON) for bit 3 of the 4th word (word n + 3) from the beginning of the PT
status control area.
Data copy is executed between the specified type and specified numbers of
memory tables. If the copy destination table is allocated to a word in the host,
the contents at the word in the host are also changed. Then, the occurrence
of a change in the contents of the memory table is notified to the PT status
notify area.
