I'm probably really showing my ignorance this morning...
I need to filter some proximity input sensors.
If I put a timer on & a timer off in series it seems to work but oh no.
If the tmr on is first in the logic, then an ON blip is ignored, but an off blip is seen.
If the tmr off is first in the logic, then an on blip of the input is seen.
What am I missing?
p.s. the plc is a schneider m340 & I am using the function block diagram.
