When using redundant Ethernet (HSR or PRP), configure all devices
in the network before connecting cables to ports LAN A and LAN B.
Avoid using the LAN A or LAN B ports on redundant communication
modules while changing the

IED Update
The firmware update tool is used for updating the following:
•
IED firmware
•
Communication card firmware
•
LHMI firmware and application
•
License in case of Modifications Sales related update
The tool can also be used for adding or replacing IED languages. Update packages are
provided by Customer Support.
The update tool can be used either locally or remotely.
Separate update packages are needed for updating the communication
card, the LHMI and license and default configuration files. If the new
communication card firmware, LHMI firmware or application need
new IED firmware, it is updated at the same time, otherwise a second
update with the same package is needed to update the IED firmware.

Prerequisites for local and remote updates
Local update
•
It is recommended to use the LHMI’s service port X1.2 or, if an LHMI is not used,
the HMI port X0 of the communication module. The IED should be removed
from the network especially with redundant network topologies (HSR or PRP).
Remote update
•
Communication should be secured either by setting up a VPN connection or by
enabling secure communication in the IED via LHMI (
Configuration/
Communication/Protocols/Network1/FTP
).
•
Remote update can be enabled in the IED either via the LHMI (
Configuration/
Authorization/Security/Remote Update
) or by an administrator in Parameter
Setting in PCM600 (
