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 St and
E must be in the same data area.

CNTR(12)
Increases or decreases PV by one when-
ever the increment input (II) or decrement
input (DI) signals, respectively, go from
OFF to ON. SV: 0 to 9999; R: reset input.
Must not access the same TC bit as anoth-
er timer/counter. The TC bit is input as a
constant.
