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
execution condition is ON, XFER(70) copies the contents of S, S+1, ..., S+N to
D, D+1, ..., D+N.
