S Program operation
(1) When "TARGET" (touch switch No. 10) is pressed, the contents of nu-
meral memory table No. 101 (the value of the target production) is dis-
played.
(2) When "ACHIEVED" (touch switch No. 11) is pressed, the contents of
numeral memory table No. 100 (the value of the production actually
achieved) is displayed.
In this example, the contents of numeral memory table No. 51, which is refer-
enced in indirect specification is not checked. If the program is actually tested,
the contents of numeral memory table No. 51 must not be outside the range of
0100 to 0101.
By using the lamp bit of the touch switch, it is possible to identify which of the
numeral memory tables is used for display. For details, refer to 7-7 "Touch
Switches" (page 334).
