positioning
Data set pointer for
constant-speed control
!
Indicates the last
positioning data input
to the PCPU.
!
Each time the
positioning at a point
is completed, the
value increases by
one.
PLC set pointer
!
Indicates the last
positioning data
updated by the
sequence program
last time.
!
The user controls
this pointer in the
sequence program.
