Adding a Second Linking Device to form a Redundant Set
of Linking Devices
For adding a second linking device to an already commissioned linking device that
is operating in the role "Primary, no backup", the following steps are required:
1.
2.
Make sure not to permute the H1 terminal blocks! An accidental permutation of
the H1 link connections at the secondary linking device will not be detected right
away. On application level detection will not be possible before a redundancy
switch-over takes place or the live lists of primary and secondary linking device
are being compared manually.

Set the IP configuration (IP address and subnet mask) of the second linking
device in a way that it is in the same IP subnet as the Primary Device. See
Network Configuration
Connect the H1 links to the terminal blocks of the H1 interfaces. Make sure to
connect each H1 link to the same channel (FF 1.. FF 4) on both linking devices.
Connect the second linking device to the Ethernet switch or hub.
Connect both serial ports by means of an RS-232 null modem cable (Article
No: 3BDH000281R1).
Connect the second linking device to a 24 V DC power supply. Use different or
redundant power supplies for redundant linking devices.
After turning on the power supply the boot process takes approx. 50 seconds.
The second linking device will take over the configuration data from the
Primary Device and will start operation in the role "Secondary". For indication
of proper operation as a Secondary Device, refer to
32.
Configure linking device redundancy within the configuration tool (Fieldbus
Builder FOUNDATION Fieldbus or Control Builder F) and - if an OPC Server
FOUNDATION Fieldbus is used - download the OPC server.
