Mitsubishi FX1S Series User Manual

FX Series Programmable Controlers Applied Instructions 5
5-2
• For instructions that operate continuously, i.e. on every scan of the program the instruction
will operate and provide a new, different result, the following identification symbol will be
used ‘
(’ to represent a high speed changing state. Typical instructions covered by this
situation have a strong incremental, indexable element to their operation.
• In most cases the operands of applied instructions can be indexed by a users program. For
those operands which cannot be indexed, the symbol ‘
)’ has been used to signify an
operand as being ‘fixed’ after it has been written.
• Certain instructions utilize additional data registers and/or status flags for example a math
function such as ADD (FNC 20) can identify a zero result, borrow and carry conditions by
using preset auxiliary relays, M8020 to M8021 respectively.
