Symbol Execution Condition
No symbol
recorded
Instruction executed under normal circumstances, with no regard to the ON/OFF status of conditions prior to
the instruction.
If the precondition is OFF, the instruction will conduct OFF processing.
Executed during ON; instruction is executed only while the precondition is ON. If the preconditions is OFF,
the instruction is not executed, and no processing is conducted.
Executed once at ON; instruction executed only at leading edge when precondition goes from OFF to ON.
Following execution, instruction will not be executed and no processing conducted even if condition remains
ON.
Executed during OFF; instruction is executed only while the precondition is OFF. If the precondition is ON,
the instruction is not executed, and no processing is conducted.
Executed once at OFF; instruction executed only at trailing edge when precondition goes from ON to OFF.
Following execution, instruction will not be executed and no processing conducted even if condition remains
OFF.
