---| / |--- Normally Closed Contact

Symbol
---| / |---
Description
---| / |--- (Normally Closed Contact) is closed when the bit value stored at the specified

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
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.
