---( S ) Set Coil


---( S )    Set Coil
Symbol
<address>
---( S )

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

Description
---( S ) (Set Coil) is executed only if the RLO of the preceding instructions is "1" (power flows to the
coil). If the RLO is "1" the specified <address> of the element is set to "1".
An RLO = 0 has no effect and the current state of the element's specified address remains
unchanged.
MCR (Master Control Relay) dependency
MCR dependency is activated only if a set coil is placed inside an active MCR zone. Within an
activated MCR zone, if the MCR is on and there is power flow to a set coil; the addressed bit is set to
the "1" state. If the MCR is off, the current state of the element's specified address remains unchanged
regardless of power flow status.


The signal state of output Q4.0 is "1" if one of the following conditions exists:
The signal state is "1" at inputs I0.0 and I0.1
Or the signal state is "0" at input I0.2.
If the RLO is "0", the signal state of output Q4.0 remains unchanged.

If the example rungs are within an activated MCR zone:
When MCR is on, Q4.0 is set as described above.
When MCR is off, Q4.0 is left unchanged regardless of RLO state (power flow status).
