Function
n
AND n
Obtains AND of the previous operation result and the a-contact operation.
n
ANI n
Obtains AND of the previous operation result and the b-contact operation.
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
WR0 = WR0 + 1
Y100 DIF1
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.
