Section 4-3
• Content upgrade memory table entry (refer to page 126)
The number of the numeral memory table entry is written to the word when
the numeral memory table entry contents change due to the System keys
operation on the NT11.
The contents of the word to which the numeral memory table entry has been
allocated also change.
As the number of the numeral table entry is written, the PT status numeral set-
ting strobe flag is simultaneously set ON (1). After this is notified to the PLC,
this flag reverts to OFF (0). Checking the status of this flag will provide a sim-
ple method of checking if a number has been input from the NT11.
Note that this function is not available with the character-string memory table.
• PT status (refer to page 132)

or OFF of the bits as shown below.
