When CIO 000000 is ON, the block program is executed. After A is executed,
B and the IORF(184) after it will be executed repeatedly until CIO 000001 is
ON, at which time C will be executed and the block program will end.

5-35-7 BLOCK PROGRAM PAUSE/RESTART : BPPS<011>/BPRS<012>
N: Block program number # (00 to 99)
Operand Data Area Ladder Symbol
BPPS<011> N
BPRS<012> N
BPPS<011> is used inside one block program to suspend the execution of
another block program. BPRS<012> restarts the specified block program.
These instructions are effective whenever executed, i.e., they do not rely on
operand bit status or execution condition.
Precautions Even if the execution of a block program is suspended, PVs of all operating
TIMW<013> timers and TMHW<015> high-speed timers with timer numbers
T0000 through T0255 in the block program are updated continuously.
