ABB LD800HSE FOUNDATION Fieldbus Linking Device
Safety Summary (continued)
SPECIFIC
CAUTIONS
In a redundant set of linking devices, removing the power supply, the
Ethernet cable from the Primary Device causes a redundancy change over. Before doing so, make sure that the Secondary Device is opera tional
(and not still booting due to a prior change-over). Otherwise the
system breaks down or the configuration information might get lost.
Therefore wait at least one minute between such checks. See page 44
In case of removing the RS-232 cable only, redundancy is being lost but
no redundancy switch-over is done.
Make sure that the RS-232 cable is connected before plugging in the
power terminal block.
If the replaced linking device is powered while the serial link is missing, it
will behave like an independent, non-redundant Primary Device. If in this
case the linking device has a valid (possibly unknown) configuration, it
might use H1 node addresses which are already in use on the H1 links.
This will disturb or interrupt communication and application processing on
the H1 links. See page 45
Before connecting the linking device to your LAN network, make sure that
its IP address is not used by another network station. See page 50
SPECIFIC
CAUTIONS
After a firmware update (flash memory update), all FF configuration data
will be lost, but the IP configuration is still valid. See page 66
Make sure that in your configuration the maximum number of republished
signals per second per H1 link is not exceeded. See page 99
Detecting a loss of an H1 connection between the Primary Device and the
entire H1 link requires that at least two H1 devices have been connected
to that H1 channel of the linking device and have appeared in the H1 Live
List before the loss of the connection occurs. See page 114
Only one of the listed faults may be present at a time. Another fault cannot
be tolerated until the redundant set has been repaired and a fully opera tional Secondary Device is available. See page 115
Any security measures described in this User Manual, for example, for user
access, password security, network security, firewalls, virus protection, etc.,
represent possible steps that a user of an 800xA System may want to consider
based on a risk assessment for a particular application and installation. This risk
assessment, as well as the proper implementation, configuration, installation,
operation, administration, and maintenance of all relevant security related
equipment, software, and procedures, are the responsibility of the user of the
800xA System.
