Notes
•
Edge detection (DIF, DFN) cannot be used in respect to ANI.
•
Pay close attention if the external output is to be monitored when counter input (coincidence output), PWM output, or pulse
output is set with the PI/O function.
R0 Y100 DIF1
WR0 = WR0 + 1
Y100 will not change when monitored. It will remain the same value previously set using functions such as
set/reset.
For example, if Y100 is off, the Y100 status will not change while being monitored and WRO will also remain unchanged.
Program example
X00002 R010
X00003 R011
Program description
•
When input X00002 and R010 are both on, output Y00100 is on and all others are off.
