A part program section between a start label and end label
Functionality
Via
REPEAT
in part program block N160, the part program processing branches to the part program block N120
that is labeled
START_1
with a start label. This part program block and all the part program blocks up to and
including the part program block marked with the end label
END_1
(N140) are repeated x number of times. If P is
not specified, the part program section (N120 - N140) is repeated exactly once. After the last repetition, the part
program is continued with the part program block N170 following the
REPEAT
instruction.

Note
Label search direction
The program section marked with the Start and End labels can come before or after the
REPEAT
instruction. The search initially commences toward the start of the program. If the
Start label is not found, a search is made in the direction of the program end.
If the
REPEAT
instruction is between the Start and End label, only the part program section
from the Start label to the
REPEAT
instruction is repeated.
REPEAT
instruction repeated.
