Required at the end of the program.
END(01)
If interlock condition is OFF, all outputs
are turned OFF and all timer PVs reset
IL(02)
between this IL(02) and the next
ILC(03). Other instructions are treated
ILC(03)
as NOP; counter PV are maintained.
Cause all instructions between
JMP(04) and the corresponding
JMP(04)
JME(05) to be ignored. Corresponding
JME is next one in program; only 8
JME(05)
JMP-JME pairs allowed per program.
Is used in the definition of program
sections. STEP N marks the beginning
STEP(08) N
of the section identified by N. STEP
without an operand indicates the end
STEP(08)
of a series of program sections.
SNXT resets the timers and clears the
data areas used in the previous pro-
SNXT(09) N
gram section. SNTX must also be
present at the end of a series of pro-
gram sections.
Creates a bit shift register from the
starting word (St) through the ending
I
word (E). I: input bit; P: shift pulse; R:
SFT(10)
P
reset input. St must be less than or
St
equal to E and Bg and E must be in the
E
R
same data area.
Defines a bit (B) as a latch controlled
S
by set (S) and reset (R) inputs.
KEEP(11)
B
R
Increases or decreases PV by one
II
whenever the increment input (II) or
decrement input (DI) signal goes from
CNTR
DI
OFF to ON. SV: 0 to 9999; R: reset in-
N
put. Must not access the same TC bit
R SV
as another timer/counter. The TC bit is
input as a constant.
