ABB
Grid Automation Controller
COM600
Product version: 4.0
to establish a holistic view of all network
devices utilizing GOOSE and the status of the
communication between them. The viewer
also provides a continuous list of latest
sent values and real-time events. Query of
historical events is also supported.

8. Logic processor

COM600 offers 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
enables programming and execution of
automation tasks. In addition, the IEC 61131-
3 programming in COM600 offers on-line
and off-line functionality for engineering and
diagnostics.
The logic processor is suitable for post-
processing of data from the IEDs and for
programmable control of outputs of the
IEDs. Any analog or binary data, collected
from the IEDs, can be processed in the logic
program. The result of the established logic
can be displayed in the HMI and sent as a
command to an IED or to a remote control
center utilizing one of the slave protocols of
COM600.
COM600 offers a framework for sequence
control. The framework includes HMI
functions for controlling and monitoring
sequence execution and a logic processor
library for creating the sequence logic. With
the help of sequences the operator can run
control sequences that will operate multiple
switching devices, e.g. circuit breakers,
sequentially to a certain state.
9. Access control and
substation security
To protect COM600 from unauthorized
access and to maintain information integrity,
COM600 is provided with a four-level,
role-based authentication system with
administrator-programmable individual
passwords for the viewer, operator, engineer
and administrator level. Further, the security
features include host-based firewalls and
communication encryption using the secure
HTTPS (hypertext transfer protocol secure)
protocol.
10. Substation
integration
COM600 provides connectivity to a range
of ABB systems. The connectivity to ABB's
low voltage motor control center MNS iS is
provided using an OPC server in COM600.
COM600 receives data from the MNSiS
devices and provides a human-machine
interface (HMI) and gateway functionality for
a smooth integration. Further, COM600 offers
connectivity to ABB's Automation System
800xA and MicroSCADA by means of OPC or
other communication protocols.
