---| / |--- 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.
Status word

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
