Block Programming Instructions
Description
Flags
Precautions
BPRG(096) executes the block program with the block number designated in
N, i.e., the one immediately after it and ending with BEND(801). All instruc-
tions between BPRG(096) and BEND(801) are executed with ON execution
conditions (i.e., unconditionally).
When the execution condition for BPRG(096) is OFF, the block program will
not be executed and no execution time will be required for the instruction in
the block program.
Execution of the block program can be stopped using BPPS(811) from within
another block program even if the execution condition for BPRG(096) is ON.
