COM600S project
The relay connectivity package supports SAB600. An REX640 protection relay is
imported as an REX640 device. It is also possible to import a full PCM600 project
including several protection relays to SAB600. In this case, PCM600 project
information is imported to SAB600 using a SCD file.
The REX640 device supports several functions in COM600S.
•
Controlling the switchgear
•
Monitoring the measured values
•
Reading disturbance recordings
•
Setting parameters
4.5.1
Selecting communication port for configuration
When a relay is configured in a PCM600 project, the connection between the relay and
the tool can be established using a point-to-point link between the relay's HMI port and
the computer or by connecting the computer to the relay's LAN port over an Ethernet
station bus. In PCM600, the HMI or LAN communication port can be selected from
the project structure.
When using the HMI port, DHCP server functionality must be activated in the
computer network adapter settings to get the IP address from the relay. Alternatively,
the computer network adapter IP address can be set manually to the same subnet range
as the HMI port.

Communication port options
•
Check that the settings are correct to ensure successful configuration access to the
relay.
•
Computer port settings must match the relay settings (IP address, subnet
mask, DHCP).
•
Any firewall in the computer or in the network must allow the required
communication services.
•
When using the HMI port and switching the connection from the computer
to another relay, it takes some time before the computer refreshes the relay's
MAC address for the HMI port IP address automatically. The MAC address
can also be reset manually by clearing the computer ARP table.
