Numeral Setting

Notification of Numbers to the PC
This section describes how the numerical data input at an NT11S is ascertained by
the PC.
In order to determine when numerical data has been input at the NT11S, the nu-
meral setting strobe flag in the PT status notify area is used. In order to determine
the upgraded numeral memory table number, the “content upgrade memory table”
in the PT status notify area is used.
When numerical data is input at the NT11S, this is automatically notified to the PT
status notify area (PT
®
PC) allocated in the PC memory as follows.
Notification of upgrade:
PT status numeral setting strobe flag
turned ON (1)
Upgraded numeral table number: Stored in the “content upgrade memory
table”
When the PC reads the “content upgrade memory table” at the leading edge of the
numeral setting strobe flag, it determines the numeral memory table number in
which the numerical data that was changed at the NT11S is stored.
