Input Indications (SP & DP)
Commands (control actions) are output indications which are specially configured for
the transmission of control signals to switching devices (circuit breakers, etc.).
q
For each device to be controlled, determine if switching is to be done with 1 contact,
1
1
/
contacts (single contact and common), or 2 contacts; with a single or double
2
command; and with or without feedback signals. See Table 5-1 and Figures 5-4 to
5-12. The information to be processed and the command type are determined with
these decisions.
q
Assign the necessary binary inputs and outputs in the SIPROTEC
specific function. Important to note are:
− Messages and commands associated with a switching device must always occu-
py sequential binary inputs and outputs in the SIPROTEC
− The TRIP (OFF)–command is always configured prior to the associated CLOSE
(ON)–command;
− Limitations may arise because of the commoning of some binary inputs and out-
puts in the SIPROTEC
When the types of commands have been established, DIGSI
sponding number of relay outputs contacts. For this, the corresponding output con-
tacts are numbered consecutively. This must be observed when wiring the relays to
the corresponding equipment to be controlled.
Table 5-1 shows the most important command types. They are made available as op-
tions in the Configuration Matrix for the SIPROTEC
for Switching Devices" in Sub-section 5.2.4). All double commands, with and without
feedback indications, are also available as transformer step commands. The following
Figures 5-4 through 5-12 show time diagrams, control settings, and the sequence of
relay positioning in the configuration matrix for frequently used command types.
