● Operands indicate the targets of operation and/or methods for operation processes. There
are three types of operands: [S], [D], and [n]. The number and types of operands that need to
be specified vary by instruction.

Every Scan Execution Type and Differential Execution Type
● For high-level instructions, there are two execution types: every scan execution type and
differential execution type.
(1) Every Scan Execution Type
This type of instruction is executed repeatedly for every scan while the internal relay is
established.

High-level instruction

OFF
Executed
Single scan
(2) Differential Execution Type
This type of instruction is executed only for a single scan when a leading edge or trailing edge
of the internal relay is detected.
