Changing Numeral and Character String Display
Section 8-5
(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 hex-
adecimal notations is used is determined by the setting for “PT Configuration”
– “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 con-
trol area as indicated below to match the type of memory table for which copy-
ing is to be executed.
Memory table type: Bit 2
- Character string memory table: 0 (OFF)
- Numeral memory table: 1 (ON)
(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.
(4) After the execution of memory table copying, return the setting for bit 3 of the
4th word (word n + 3) from the beginning of the PT status control area to “0”
(OFF).
