HIGH SPEED SERIAL LINK (HSSL)
The redundant controllers are connected
together by a dedicated high-speed serial link.
This link is a pre-fabricated cable that has a
custom connector for ease of use. Redundant
controllers are automatically addressed with
the HSSL cable. One end of the cable is
labeled Primary. The primary controller takes
address 1, while the secondary controller is
address 2. The significance this has for the
user is that the primary is the default master
when both controllers are powered-up at the
same time.
CONFIGURATION
S
³
Conguration
The S
³
configuration software is used to
configure the redundant controllers. A check
box on the controller configuration screen must
be enabled and downloaded to the controllers.
IMPORTANT
If the controllers have not been
configured for redundancy via the S
³
conguration software, redundancy will
not function.
Controller Addresses
The LON addresses are pre-determined and
cannot be adjusted. Address 1 and 2 have
been reserved for a redundant controller
configuration.
RS-485/RS-232 (Port 1 through Port 4)
RS-485/RS-232 ports 1 through 4 on each
controller share the serial settings including
baud rate and address. Controllers in standby
mode don’t respond to or issue Modbus
RTU messages. This allows for transparent
switching on a multi-drop network. If RS-232
is used, a relay switching mechanism can be
used.
ControlNet
The ControlNet interface on each controller
will have a different address. This allows both
controllers to reside on the same ControlNet
network at the same time. The primary
controller uses the configured address while
the standby assumes an address 1 higher than
the primary controller. Application logic in the
attached PLC must be used to determine which
controller has the correct output information.
Information coming from the PLC should be
written to both Premier Controllers.
EtherNet DLR
The EtherNet DLR interface on each controller
will have a different address. This allows both
to reside on the same network at the same time.
The primary controller uses the configured
address while the standby assumes an
address 1 higher than the primary controller.
Application logic in the attached PLC must
be used to determine which controller has the
correct output information. Information coming
from the PLC should be written to both Premier
Controllers.
Ethernet
The Ethernet interface ports on each controller
will all have unique IP addresses. This allows
both controllers to reside on the same Ethernet
network at the same time. The primary and
secondary controller IP addresses for ports
3 and 4 are part of the configuration data.
During the configuration download, the primary
controller assigns the primary IP address to
itself and passes the secondary IP address
on to the secondary controller. Controllers
in standby mode do not respond to Modbus
TCP/IP messages. Ethernet applications need
to redirect to the alternate IP address when
controller switchovers occur.
