Multistate Output Mapping (Pulse)

MO(X)_PULSE_(X)CHA_(X) (SIMATIC Manager hardware catalog)
Parameter for mapping the multistate process value to a specific number of output
channels.
The multistate output (pulse) is similar to the function of
the Q250-P (BO_OnOff_Pulse).
The function has n combined outputs. n is independent
of the TX-I/O module that is used.
The function ensures that only one output can be active
at any one time.
If a new process value is set, the following steps are
performed in succession:
The OFF relay [Out_X(n)] is activated
The OFF relay [Out_X(n)] enables the circuit
The OFF relay [Out_X(n)] is disabled
One of the contact relays [Out:X(n+1)]... [Out:X(n+s)] is
activated
After the pulse has expired, the corresponding contact
relay is disabled.
Note
 The first channel of the [MO_PULSE] function is always the OFF channel.
 If a pulse with the pulse length [MinOffTime] was generated in the OFF channel
before a change in the value [MOValue], it cannot be interrupted by changing
the value.
We distinguish between three different [MO(n)_PULSE] function types. The
following table shows the channels in regard to function and representation in the
SIMATIC Manager hardware catalog:

These function groups must be inserted in the subslots
 without any changes to the order and
 in direct succession to each other.
