PRODUCT SETUP
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
5.3.4.9 Protocol selection
SETTINGS  PRODUCT SETUP  COMMUNICATIONS  PROTOCOL
 PROTOCOL

The menu allows selection of one of the following protocols: DNP 3.0, IEC60870-104, or IEC60870-103.
PROTOCOL
— This setting selects the SCADA protocol on which the unit communicates, among DNP3.0, IEC 60870-
SCADA PROTOCOL
104, and IEC 60870-103, with DNP being the default. Options depend on order code. For any change to take effect, restart
the unit.
MMS CONNECTION TIMEOUT
no data traffic on the TCP connection for greater than the time specified by this setting, the connection is aborted. This
frees up the connection to be re-used by a client. For any change to take effect, restart the unit.
The table shows which of DNP 3.0, IEC 60870-5-104, IEC 60870-5-103, and IEC 61850 protocols are operational on the
RS232, RS485, and Ethernet ports. It shows all possible combinations of the
