Edge Generation – IL
PLC3000 does not include Rising and Falling Edge functions. However, they can easily be generated from the available memory bits
Generation in IL
Generate a Rising Edge on %I0 is done by considering a memory bit, e.g. %M1, such as
LD %I0 ANDN %M0 ST %M1 LD %I0 ST %M0
Generate a Falling Edge on %I1 is done by considering a memory bit, e.g. %M3, such as
LDN %I1 ANDN %M2 ST %M3 LDN %I1 ST %M2
