For setting [
RedundantMode
]=
Hot-standby
, an IP address should be assigned for
the both A and B pots (i.e., a single one is set for the both; see Table 11.2-4).
Similarly, for [
RedundantMode
]=
PRP
/
HSR
/
RSTP
, an IP address will be assigned
for the both (see Table 11.2-5).
When setting [
RedundantMode
]=
Fixed
, two IP addresses can be assigned for the
respective ports, provided two ports are sited (see Table 11.2-5).
‡Note: Chapter
User interface: Setting sub-menu describes how to set the address on the
IED screen.
11.2.2
Redundant LAN (Hot-standby)
Hot-standby is designed to change to another LAN path if an error occurs on the LAN
communication; accordingly, the LAN communication can have more security (i.e. “Redundant
communication”). The “Hot-standby (HOTST)” operation is possible when the IED has dual
communication modules for the LAN network. The Hot-standby runs when the user sets
Hot_Standby
for scheme switch [
RedundantMode
]†.
†Note: When the user wishes not to operate Hot-standby, or the network is not ready for
the redundant, set
Fixed
for the [
RedundantMode
]. Port B (located at C12 if
provided) can only operate for the connection with the engineering tool (GR-
TIEMS®) or the PLC editor (MULTIPLOG®).
‡Note: See Chapter
Technical description: Signal processing and communication
module.

Overview
For the Hot-standby communication, the first communication module for Network is used as
the primary port, (i.e. Port A at C11) while a second communication module for Network, (i.e.
Port B at C12) is used as the secondary port; the IED will communicate using Port A for normal
operation. If a communications failure occurs at Port A, the IED can automatically switch
communication from Port A to Port B.
When the IED detects the occurrence of a communications failure, for which the LAN
module is unable to respond to the IED (i.e. a communications link is down), the IED starts a
timer. When the timer exceeds a setting [
DownTime
], the IED will switch ports. Thus, Port B
is then used for communications. (Note that Port A can be determined to be the secondary port
on the occurrence of the failure. If Port B is unable to continue to operate, then Port A will be
re-switched to run after a predetermined setting [
UpTime
]. Then, Port B will be discriminated
as the secondary port.)
