TCP/IP
Modbus TCP uses TCP/IP protocol. Also SetPointPS and SPA-bus
and DNP 3.0 communication can be directed via TCP/IP.
The IP address, net mask, gateway, name server and NTP server are
common with the internal Ethernet port setting.
Table 7.13 – TCP/IP Parameters
Parameter Value Unit Description Set
IpAddr n.n.n.n Internet protocol address (set with
SetPointPS)
Set
NetMsk n.n.n.n Net mask (set with SetPointPS) Set
Gatew default = 0.0.0.0 Gateway IP address (set with
SetPointPS)
Set
NameSv default = 0.0.0.0 Name server (set with SetPointPS) Set
NTPSvr n.n.n.n Network time protocol server (set
with SetPointPS)
0.0.0.0 = no SNTP
Set
Port 502 = default Port 502 is reserved for Modbus
TCP
Set
Set = An editable parameter (password needed)
External I/O (Modbus RTU master)
External Modbus I/O devices can be connected to the relay using this
protocol. (See “External input/output Module” in Chapter 9 for more
information).
IEC 61850
IEC 61850 protocol is available with the optional 61850 interface.
The protocol can be configured to transfer the same information
which is available with the IEC 103 protocol. When IEC 61850 is
used, the Remote port protocol of the relay is set to IEC-103.
