---| / |--- Normally Closed Contact (Address)


---| / |---    Normally Closed Contact (Address) 
Symbol 
<address>
  ---| / |---

Parameter Data Type  Memory Area Description
<address>  BOOL  I, Q, M, L, D, T, C  Checked bit
Description
---| / |--- (Normally Closed Contact) is closed when the bit value stored at the specified <address> is
equal to "0". When the contact is closed, ladder rail power flows across the contact and the result of
logic operation (RLO) = "1".
Otherwise, if the signal state at the specified <address> is "1", the contact is opened. When the
contact is opened, power does not flow across the contact and the result of logic operation
(RLO) = "0".
When used in series, ---| / |--- is linked to the RLO bit by AND logic. When used in parallel, it is linked
to the RLO by OR logic.

Power flows if one of the following conditions exists:
The signal state is "1" at inputs I0.0 and I0.1
Or the signal state is "1" at input I0.2
