Addition
lTubject
The data register D O is cleared by ON of input XO1, and flicker (0.5
- I -
0.5 sec) for the
timers TO and T1 is started simultaneously.
With each flicker,
+
2 is executed for the data register DO, and the output Y 10 becomes
ON when the contents of D O become 20.
(DO is monitored to confirm program operation.)
Programming outlines
Data processing for addition of the external input signal X1 at each timer flicker, etc., is ex-
ecuted by the internal pulse formation and processing of this signal.
