Memory Table Entries and Bar Graph
Section 5-3
*1 LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2 The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
The range of respective area varies with the type of PLC. Refer to Appendix H
Special Characters (page 163).
Reference
1. Use the support tool to allocate the PT status control area (PLC to PT) to
the PLC memory.
2. Register the memory table entries for the numerals and character-strings
to be displayed when creating the screen data by using the support tool.
To display a character-string, use “character display” and specify the char-
acter-string memory table entry by using the support tool.
To display numerals, use “numeral display” and specify the numeral mem-
ory table entry by using the support tool.
3. Set the copy source data to the memory table entry when creating the
screen data by using the support tool.
Use “table edit”.
4. Create a PLC program to write the copy type, copy destination memory ta-
ble entry number, and copy source memory table entry number to the
“copy memory table entry” setting word in the PT status control area.
• Order for writing to the PT status control area (PLC 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 (PLC to PT).
The NT11 reads the area sometimes when the PLC is writing the settings.
If the “copy source memory table entry number” has been written first and
is changed, an unexpected memory table entry may possibly be changed.
• Allocated words that the NT11 reads
The NT11 reads the allocated words in the PLC for the memory table en-
tries which need to be displayed. If the copy source memory table entry is
allocated to a PLC word, it may sometimes be used at the initialization only.
• 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. To repeat copying of the same copy source and same copy
destination, write a value other than “0” or “1” for the copy type, and then,
write a correct value again.
• Copying a numeral memory table entry
If the display method or the number of registered words include discrepan-
cies, a numeral memory table entry may not be copied and displayed cor-
rectly.
