Upgraded Memory Table Entry in the PT Status Notify Area and PT Status
Data is written to the upgraded memory table entry as three digits of BCD
(binary coded decimal) data.
When the numeral setting strobe flag bit has been updated in the PLC it
returns to the OFF (0) status.
For details on the method for storing a number in the word allocated for the
numeral memory table entry, refer to
5-2-1 Displaying the Contents of Allo-
cated Words of Memory Table Entries
on page 180.
• Restrictions on Allocating Words
The PT status notify area can be allocated to the PLC memory areas listed
in the following table.
❍

: NG
Since all the CVM1/CV-series AR area bits are allocated to the system, they
cannot be used for applications not related to the system.
The range of each memory area differs according to the PLC type.
Note
(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.
