The 650 series supports two Ethernet communication protocols. These protocols are IEC61850,
and DNP3/TCP. These communication protocols are enabled by configuration. This means that the
Internet Protocol port is closed and not available if the configuration of the 650 series doesn't
contain a communication line of the protocol. If a protocol is configured the corresponding
Internet Protocol port is open all the time.
There are some restrictions and dependencies:
• The Internet Protocol port used for file transfer (default port 21) is fixed and cannot be
changed.
• The Internet Protocol port used for DHCP (default port 67) between the IED and a computer is
fixed and cannot be changed.
• The Internet Protocol port used for IEC61850 (default port 102) is fixed and can not be
changed.
• The Internet Protocol ports used for DNP3 are configurable. The communication protocol
DNP3 could operate on UDP (default port 20 000) or TCP (default port 20 000). It is defined in
the configuration which type of Ethernet communication is used. Only one type is possible for
a specific configuration.
Two ports are used by PCM600; for configuration and parameter settings the Internet Protocol
port for a proprietary ODBC protocol is used (port 2100), the port is fixed and cannot be changed.
For monitoring events and clear commands the Internet Protocol port for a proprietary SPA
protocol is used (port 7001), the port is fixed and cannot be changed.
These security drawbacks are acceptable in limited local networks. For wide area networks in
particular with connection to the Internet, the 650 series Ethernet communication must be
protected against illegal access. This protection must be handled by external devices to setup a
secure virtual private network (VPN).
