Function(s) programmed using IPScom

There are four initiating input sources: Initiating
Outputs, Initiating Function Trips (including the
IPSlogic Functions themselves), Initiating Inputs,
and initiation using the Communication Port. The
only limitation is that an IPSlogic Function may not
be used to initiate itself. There are two blocking
input sources: Blocking Inputs and blocking using
the Communication Port.
The IPScom IPSlogic Function programming screen
and Initializing Function Trip Selection screens are
shown in Figure 4-62, 4-63 and 4-64, respectively.
The activation state of the input function selected
in the Initiating Function Trip dialog (Figure 4-62)
is the Tripped state, not Pickup. If the user requires
an initiating input that indicates a Pickup status,
this can be achieved. Since most functions have
multiple setpoints, the second setpoint can be
set with no intentional time delay and used as the
initiating input. The desired time delay for security
considerations can be obtained in the IPSlogic
Function time delay setting.
The IPSlogic Function can be programmed to per -
form any or all of the following tasks:
• Change the Active Setting Profile
• Close an Output Contact
• Be activated for use as an input to another
External Function
Since there are six IPSlogic Functions per setting
profile, depending on the number of different relay
settings defined, the scheme may provide up to 24
different logic schemes. The IPSlogic is illustrated
in Figure 4-61, and the IPScom
