This is an example for explaining the ON/OFF control of the output by one revolution of table (0 to 360
degrees).
(Rotation angle signal one degree per pulse)
Data table (occupying n lines × 4 points) of n lines from the device designated in is compared with the
present value of the counter of the device designated in , and outputs of n points continuous from the
device designated in are controlled to be ON/OFF.
1) Write the following data in ( , +1) to ( +4n+2, +4n+3), preliminarily by using transfer
command.
For example, store rising point data and falling point data alternately.
2) Output pattern
When command input is turned ON, n points are changed as follows, starting from the device designated
in .
Rise point and fall point may be individually changed by rewriting data in ( +1, ) to
(+(n×2)+3, +(n×2)+2).
