• The STL instruction cannot be used within interrupt programs and subprograms.
• Though jump instructions are not prohibited within the STL instruction, these instructions are not recommended
because of their complex actions.

LD& LD logical AND operation
Logical operation is
performed bit by bit. 32-bit
(9-step) operation and 16-
bit (5-step) operation are
supported. Two operands are
included in every operation.
The execution result is used
as the contact status.
