3-6 Communicate with Your Module
Gray to Binary Conversion No/Yes Convert data from Gray to
binary
SSI Word Delay Time (t
m
) 16 µs… to 64ms (64µs) Delay time between
successive SSI data words
SSI Word Filter Control Off, Low, Med, High, Max Corresponds to the number
of successive equal SSI data
words that must be received
by the module in order to
update the real-time present
SSI data word.
Standardization Off/On Off = Use entire data word
length specified by Data
Word Length parameter.
On = Data is right-shifted
the number of bits specified
in the Trailing Bits
parameter.
Trailing Bits 0… 16
Sensor Resolution 1… 65535 Total number of
positions/revolution for a
rotary encoder,
positions/stroke for a linear
displacement transducer, or
maximum counts for
distance measurement.
Sensor Cycles 1… 65535 Total number of revolutions
for a rotary encoder, strokes
for a linear displacement
transducer
Latch Input Off, Rising Edge, Falling
Edge, Both Edges Master unlatches data by
transmitting the LACK bit
over the network
Comparator 1 Not Active, Up Direction,
Down Direction, Both
Directions Module compares data to
value from the master. Only
one Compare value can be
active.
Comparator 2 Not Active, Up Direction,
Down Direction, Both
Directions Module compares data to
value from the master. Only
one Compare value can be
active.
