Redundancy Master
RedundancyMaster increases the reliability and availability of OPC data by allowing multiple OPC Servers to be configured into redundant pairs. These redundant OPC Server pairs seamlessly appear as a single OPC Server to any OPC Client application.
Price: $1,295 US
RedundancyMaster can be a drop in
application that does not require you to
make any changes to your OPC client or
server applications. Its intuitive
configuration takes only minutes and
will allow you to have a redundant OPC
system running with no headaches.

Broadcasting Proprietary
Ethernet IP Data
This diagram shows how the
proprietary Ethernet IP data
is manipulated within the
plug-in device driver of
KEPServerEX to become OPC
Data, which is then served
out to the OPC Client in a
basic redundant system.

Local Machine Redundancy
This scenario has the OPC
Client, RedundancyMaster, and
the Secondary OPC Server
residing on the Local Machine
with the Primary OPC Server on a
Remote Machine. In this scenario
be sure to make the most
reliable Server your Secondary
OPC Server. This scenario also
reduces the need for another
machine to run the Secondary OPC
Server. |

Single OPC Server Pair
Redundancy
This is a standard use diagram
for one Server Pair where
RedundancyMaster resides on the
same machine as the OPC Client,
and the two OPC Servers are on
remote machines.

Multiple OPC Server Pair
Redundancy
RedundancyMaster can be
configured to have multiple OPC
Server Pairs. In this diagram
there are two pairs of OPC
Servers which are gathering data
from two separate device
networks. If the multiple OPC
Server Pairs are all of the same
ProgID (KEPware.KEPServerEx.V5),
then you will need to use the
Aliasing feature; if the two
pairs have different OPC Servers
with different ProgIDs then you
will not need the Aliasing
feature. |
