I ntroduction
The SmartAXIS provides dedicated instruction set for each programming language.
The instructions for ladder programs are divided into basic instructions, which perform sequencing, and advanced instructions,
which perform moves, comparisons, Boolean computations, binary arithmetic operations, bit shifts, and other operations. For
details, see the SmartAXIS Ladder Programming Manual.
A series of function blocks are provided for FBD programming such as logical operation function blocks that perform logical
operations, timer/counter function blocks to perform processing using timers and counter devices, and pulse output function
blocks that perform pulse output.
