the user to understand the process dynamics.
It further provides required information for
learning how to keep the process running.
High performance and reliability, together
with maintenance-free operation, provide a
solid platform for trending. The optional data
historian functionality offers means of stor-
ing, analyzing and presenting process data.
Please note that displaying of data historian
information using the HMI requires that Mi-
crosoft Internet Explorer is used.
7. Logic processor
COM600 offers an straightforward approach
to the languages specified by the IEC 61131-3
standard for programmable logic controllers
(PLC). The programmable logic processor in
COM600 is offered as a selectable software
option. The PLC programming system ena-
bles programming and execution of auto-
mation tasks. In addition, the IEC 61131-3
programming in COM600 offers on-line and
off-line functionality for engineering and
diagnostics.
The logic process can be used for applica-
tions such as grouping of signals or tripping
of all bus breakers, if one of the breakers
fails to clear the fault. COM600 collects any
analog or binary IED data using standard
serial and TCP/IP based protocols such as
IEC 61850, DNP3 or Modbus. In the created
logic, the logic processor, use the analog and
binary data from the IEDs. The output of the
created logic can be sent to the IEDs for trip-
ping or alarm purposes.
8. Access control and
substation security
To protect COM600 from unauthorized ac-
cess and to maintain information integrity,
COM600 is provided with a four-level, role-
based authentication system with administra-
tor-programmable individual passwords for
the viewer, operator, engineer and admin-
