Differ-
ences in
operation
Operation of instruc-
tion to read frequen-
cies (PRV(881)) and
pulse frequency con-
version instruction
If high-frequency mode is selected and
the PV is changed or reset during a
sampling interval, the results of the
instruction will not be dependable and
the P_CY Flag will turn ON.
If high-frequency mode is selected and
the PV is changed or reset during a
sampling interval, the results of the
instruction will not be dependable.
Handling of error
when changing the PV
in Ring Mode
If the new PV exceeds the ring counter
maximum value, the P_ER Flag will
turn ON when the instruction is exe-
cuted.
If the new PV exceeds the ring counter
maximum value, the instruction will be
ignored.
