---| |--- Normally Open Contact (Address)


---|   |---  Normally Open Contact (Address) 
Symbol 
      <address>
       ---|   |---

Parameter     Data Type        Memory Area             Description
<address>     BOOL          I, Q, M, L, D, T, C        Checked bit

Description
---|  |--- (Normally Open Contact) is closed when the bit value stored at the specified <address> is
equal to "1". 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 "0", the contact is open. When the contact
is open, 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 !--RELATED-POSTS-STARTS-->
