Block Programming Instructions Section 3-30
Description LOOP(809) designates the beginning of the loop program. LEND(810) or
LEND(810) NOT specifies the end of the loop. When LEND(810) or
LEND(810) NOT is reached, program execution will loop back to the next pre-
vious LOOP(809) until the operand bit for LEND(810) or LEND(810) NOT
turns ON or OFF (respectively) or until the execution condition for LEND(810)
turns ON.
Using an Execution Condition for LEND(810)
LEND(810) can be programmed either with or without an operand bit. If an
operand bit is not specified, an execution must be created before LEND(810)
starting with LD. If the execution condition is OFF, execution of the loop is
repeated starting with the next instruction after LOOP(809). If the execution
condition is ON, the loop is ended and execution continues to the next instruc-
tion after LEND(810).
