5.1 List of State Variables

5.2 State Variables

M_DSI
[Function]
Regarding DSI for functional safety, this refers to the current value.
DSI Input enabled: 1
DSI Input disabled: 0
[Format]
Example) <Numerical variable> = M_DSI( <DSI number> )
[Terminology]
<Numerical variable> This specifies where to store the DSI state.
<DSI number> This specifies a number for DSI whose state to be obtained.
Setting range: 1 to 8
[Reference Program]
M1 = M_DSI(1) 'The state of DSI1 is stored in M1.
[Explanation]
(1) Regarding DSI for functional safety, this refers to the current state.
(2) The value changes after the DSI filer setting time elapses following change in the input signals DSIn_A and
DSIn_B.
(3) Assigning a value other than 1 to 8 to <DSI number> causes the L.3880 error on execution.
