FX Series Programmable Controlers
Note: A short delay will occur before the I/O device is physically updated, in the case of inputs
a time equivalent to the filter setting, while outputs will delay for their set energized time.
REF (FNC 50)
the REF instruction is used. The REF instruction can only be used to update or refresh blocks of
8 (n) consecutive devices. The head address of the refreshed devices should always have its
last digit as a 0 (zero), i.e. in units of 10.
REFF (FNC 51)
input filters slows down the PLC response times. For high speed applications, especially where
solid state switching provides the input signal, input filter times may be reduced. The default
setting for the input filters is approximately 10 msec. Using this instruction input filter times of 0
to 60 msec may be selected. The setting ‘0’ (zero) is actually 50 sec. This is the minimum
available setting. It is automatically selected when direct input, interrupts or high speed counting
functions are used. The REFF instruction needs to be driven for each program scan if it is to be
effective, otherwise, the standard 10 msec filter time is used.

Operation :
PLC’s are provided with input filters to overcome
problems generated by mechanical switch gear.
However, as this involves ensuring a steady input
signal is received for a fixed time duration, the use of
