3.4.4.1.2 Ethernet Module
The optional Ethernet module provides an RJ45 connection and a fiber optic
interface where an Ethernet network can be connected. The selection which of
the two interfaces is to be used to connect to the Ethernet network is made by
setting the parameter [IC]: Media.
Setting parameters identified by “[IC]:…” in the IEC function group are set with the
“IED Configurator”. They cannot be modified from the local control panel (HMI) or
with the operating program.
There are two ordering variants available for the fiber-optic interface: the ST
connector and the SC connector both for 100 Mbit/s and 1300 nm. The RJ45
connector supports 10 Mbit/s and 100 Mbit/s.
The optional Ethernet module additionally provides an RS485 interface for
remote access with the MiCOM S1 support software (function group COMM2).
The P634 may be equipped with the optional Ethernet module only as an
alternative to the standard optional communication module. Therefore the
Ethernet-based communication protocol IEC 61850 is available only as an
alternative to function group COMM1.
3.4.4.1.3 Configuration and Enabling
The IEC function group can be included in the configuration by setting the
parameter IEC: Function group IEC. This parameter is only visible if the
optional Ethernet communication module is fitted to the P634. After activation of
IEC, all data points associated with this function group (setting parameters,
binary state signals etc.) become visible.
The function can then be enabled or disabled by setting IEC: General enable
USER.
The setting parameters from the IEC function group as well as the related GOOSE
function group are not automatically active in the P634. The P634 features two
memory “banks” one of which includes the active setting parameters. The other
memory bank is used with the configuration procedure for parameters from the
IED Configurator and the operating system. Specific project-related extensions of
the IEC 61850 parameters from the IED Configurator are loaded into the P634 by
downloading a .MCL file. The inactive communication parameters are activated
by executing the command IEC: Switch Config. Bank. This command may
also be issued from the IED Configurator.
