Block Programming Instructions Section 3-30
Description Operation without an Operand for IF(802)
If an operand bit is not specified, an execution must be created before IF(802)
starting with LD. If the execution condition is ON, the instructions between
IF(802) and ELSE(803) will be executed and if the execution condition is OFF,
the instructions between ELSE(803) and IEND(804) will be executed.
If the ELSE(803) instruction is omitted and the execution condition is ON, the
instructions between IF(802) and IEND(804) will be executed and if the execu-
tion condition is OFF, only the instructions after IEND(804) will be executed.
