6-3-6 Notification of Numbers to the PC
This section describes how the numerical data input at an NT600S is ascertained
by the PC.
In order to determine when numerical data has been input at the NT600S, 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 theNT600S, 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 NT600S is stored.
