Data Areas
These footnote tables show the actual ranges of all data areas. Bit numbers are provided (except for DM and TC areas); remove the rightmost two digits for word numbers.

Symbol
Used with a control bit (B) to indicate the
end of the step, reset the step, and start
the next step which has been defined
SNXT(09) B
with the same control bit.
Creates a bit shift register for data from the
starting word (St) through to the ending
I word (E). I: input bit; P: shift pulse; R: reset
input. St must be less than or equal to E.
SFT(10)
P
St and E must be in the same data area.

Defines a bit (B) as a latch, controlled by
S
the set (S) and reset (R) inputs.
KEEP(11)
B
R
Increases or decreases the PV by one
II
whenever the increment input (II) or
decrement input (DI) signals,
CNTR(12)
DI
respectively, go from OFF to ON. SV: 0 to
N
9999; R: reset input. Each TC bit can be
R SV
used for one timer/counter only. The TC
bit is entered as a constant.
DIFU(13) turns ON the designated bit (B)
DIFU(13)
B
for one cycle on reception of the leading
(rising) edge of the input signal; DIFD(14)
turns ON the bit for one cycle on
DIFD(14)
B
reception of the trailing (falling) edge.
A high-speed, ON-delay (decrementing)
timer. SV: 00.02 to 99.99 s. Each TC bit
can be assigned to only one timer or
TIMH(15) N
counter. The TC bit is entered as a
constant.
SV
The data in the words from the starting
word (St) through to the ending word (E),
WSFT(16)
is shifted left in word units, writing all
St
zeros into the starting word. St must be
E
less than or equal to E, and St and E
must be in the same data area.
Compares the data in two 4-digit
hexadecimal words (Cp1 and Cp2) and
outputs result to the GR, EQ, or LE
CMP(20)
