JME(05)
Cause all instructions between
JMP(04) and the corresponding
JME(05) to be ignored. Corresponding
JME is next one in program; only 8
JMP–JME pairs allowed per program.

Single Step
STEP(08)
STEP(08) N
STEP(08)
Is used in the definition of program
sections. STEP N marks the beginning
of the section identified by N. STEP
without an operand indicates the end
of a series of program sections.

SNXT(09)
SNXT(09) N
SNXT resets the timers and clears the
data areas used in the previous pro-
gram section. SNTX must also be
present at the end of a series of pro-
gram sections.

SFT(10)
St
E
Creates a bit shift register from the
starting word (St) through the ending
word (E). I: input bit; P: shift pulse; R:
reset input. St must be less than or
equal to E and Bg and E must be in the
same data area.

CNTR
Increases or decreases PV by one
whenever the increment input (II) or
decrement input (DI) signal goes from
OFF to ON. SV: 0 to 9999; R: reset in-
put. Must not access the same TC bit
as another timer/counter. The TC bit is
input as a constant.

DIFU turns ON the designated bit (B)
for one cycle on the rising edge of the
input signal; DIFD turns ON the bit for
one cycle on the trailing edge. The
maximum number of DIFU/DIFDs is
48.

SV
A high–speed ON–delay (decrement-
ing) timer. SV: 0.01 to 99.99 s; accura-
cy: +0.00/–0.01 s. Must not be as-
signed the same TC bit as another tim-
er/counter. The TC bit is input as a
constant.
