Example The
following example shows how to use BSET(71)
to change the PV of a timer
depending
on the status of IR 00003
and IR 00004. When IR 00003 is ON, TIM
010
will operate as a 50-second timer; when IR 00004 is ON, TIM 010 will oper
-
ate as a 30-second timer.

Limitations Both S and D may be in the same data area, but their respective block areas
must
not overlap. S and S+N must be in the same data area, as must D and D+N.
N must be BCD between 0000 and 6144.
Description When
the execution condition is OFF
, XFER(70) is not executed. When the exe
-
cution
condition is ON, XFER(70) copies the contents of S, S+1, ..., S+N to D,
D+1, ..., D+N.
