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 (FTP or ).
- Remote update can be enabled in the IED either via the LHMI () or by an administrator in Parameter Setting in PCM600 (. If the IED is in local control mode, remote update proceeds only after a confirmation is received from the user.
- Remote update can be disabled manually after the update.
- Remote update only works when the IED is connected from the Ethernet interface connector of the communication module with a custom IP address.
- Remote update via a network gateway can be assigned either to Network 1 or Network 2.
