2 PROFINET IO in SIPROTEC
2.9 Executing Switching Operations via PROFINET IO

SIPROTEC 4, Communication Module PROFINET IO, Communication Profile
C53000-L1840-C360-1, Edition 08.2012
2.9
Executing Switching Operations via PROFINET IO
2.9.1
Command Output Types for Switchgear Control
The following command types are available in the SIPROTEC device:
Double Commands
Processing of the double commands, output to the switchgear, and feedback is accomplished in the device via
2 outputs and 2 bits respectively, which are defined with 01 =
OFF
and 10 =
ON
.
Single Commands
Processing of the single commands, output to the switchgear, and feedback is accomplished in the device via
one output and one bit respectively, which is defined with 0 =
OFF
and 1 =
ON
.
A command can be output in the SIPROTEC device as continuous output or as pulse output.
Continuous Outputs
Commands are issued in the continuous output mode (controlled) if a value transition (signal edge) from
idle state
or
OFF
to
ON
is detected via PROFINET IO for the associated bit pair. The commands remain
activated until a value transition occurs from
idle state
or
ON
to
OFF
via PROFINET IO. The definitions of the
values for
idle state
,
ON
and
OFF
are described in Chapter 2.3.2 and Chapter 2.3.3.
Pulse Outputs
The SIPROTEC device independently issues a control pulse for switching switchgear, including the observation
of the parameterized times.
The switching operation (pulse output via the assigned binary outputs of the SIPROTEC device) is executed
when a value change of the associated bit pair is transmitted in the PROFINET IO output telegram
•
for double commands from
idle state
or
ON
to
OFF
or from
idle state
or
OFF
to
ON
,
•
for single commands from idle state to
ON
.
NOTE
The above definition notwithstanding, single commands and double commands in the SIPROTEC device are
controlled via PROFINET IO consistently using 2 bits of the PROFINET IO output telegram (see Chapter 2.3.2
and Chapter 2.3.3).
NOTE
The switching direction
OFF
for single commands with pulse output is not permitted and is rejected in the
SIPROTEC device.
