The Multilin 8 Series protective relay platform includes four different relays, the 850, 845,
869, and 889. Information in this manual applies to all 8 series relays unless otherwise
indicated.
The Multilin 850 relay is a microprocessor-based unit intended for the management and
primary protection of distribution feeders, as well as for the management and backup
protection of buses, transformers, and transmission lines. The 850 relay is particularly
suited to overhead feeders, where automatic reclosing is normally applied.
The Multilin 869 relay is a microprocessor-based unit intended for the management and
primary protection of medium and large sized motors. Base relay models provide thermal
overload and overcurrent protection plus a number of current and voltage based backup
functions.
The Multilin 845 relay is a microprocessor-based unit intended for the management and
primary protection of the medium to large size medium voltage (MV) and high voltage (HV)
power transformers. Both 2-winding and 3-winding transformers are supported. The 845
relay provides a number of primary and backup current and voltage based protection
functions. This system allows for control of the circuit breakers at each winding plus a
number of monitoring and control functions are also provided.
The Multilin 889 relay is a microprocessor-based unit intended for the primary protection
of small, medium and large sized generators. Base relay models provide standard
generator protection functions plus a number of current and voltage based backup
functions.

COMMUNICATIONS CHAPTER 1: INTRODUCTION
Communications
8 Series relays have a two-stage communications capability. The base CPU supports
Modbus protocol through the Ethernet, USB, serial and WiFi port. In addition, the base CPU
also supports IEC 103, DNP serial, DNP TCP/IP, and TFTP protocol. Once the
communications module option is added to the base, the base Ethernet port becomes
disabled but the two Ethernet ports on the communications module have enhanced
communications capabilities such as IEC61850, IEC62439 parallel redundancy protocol
(PRP) and IEEE 1588 Precision Time Protocol (PTP). The communications CPU also supports
Modbus TCP, IEC 104, DNP TCP, TFTP, SFTP, and SNTP protocol.

2-2 8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
WIFI CHAPTER 2: COMMUNICATION PORTS
WiFi
WiFi refers to Wireless Local Area Networks (WLANs) that are based on the 802.11 set of
standards. WLANs are essentially providing Local Area Network (LAN) type of connectivity
but without the need of cables, which makes them more convenient for use in limited
spaces. WiFi works on top of the TCP/IP stack, the same as Ethernet. The signal strength
and its range is determined by the wireless device’s antenna technology and standard, the
best being IEEE 802.11n.
WiFi defines two modes of operation, namely ad-hoc, used for small deployments, and
infrastructure mode, which supports more robust types of security and better capabilities
for centralized management. The infrastructure mode requires an access point (AP).
Devices operating in this mode pass all data through the AP.
The WiFi module integrated on the 8-Series products conforms to IEEE 802.11b/g/n
standards. The 8-Series devices operate in infrastructure mode. Security is optional, but
enabled by default and it is advisable that it is left on, as wireless traffic is very susceptible
to cyber-attacks.
The security technology used is WPA2 (Wireless Protected Access version 2), based on the
IEEE 802.11i standard for data encryption. WPA2 is a second version of WPA technology,
designed to solve known security limitations found in one of the encryption algorithms
used by WPA, namely TKIP (Temporal Key Integrity Protocol). WPA2 uses CCMP (Counter
Mode with Cipher Block Chaining Message Authentication Code Protocol), which provides
an enhanced data cryptographic encapsulation mechanism based on AES (Advanced
Encryption Standard). CCMP makes WPA2 much stronger and secure than its
predecessors, WPA and WEP.
Several forms of WPA2 security keys exist. The 8-Series supports WPA2 PSK (Pre-Shared
Key), which utilizes 64 hexadecimal digits. The key may actually be entered as a string of
64 hexadecimal digits or as a passphrase of 8 to 32 printable ASCII characters. For user
convenience, the settings accept the key in the form of a passphrase. Internally the ASCII
passphrase is used for deriving a 256-bit key.
WiFi Settings
The following are the WiFi network settings for the 8-Series product. Only an Administrator
has the rights to change them.
Path: Setpoints > Device > Communications > WiFi
WiFi Enable
This setting switches WiFi functionality on/off. By default WiFi is enabled in the basic
offering, but it is disabled in software options that offer CyberSentry.
WiFi IP Address / Subnet Mask
The default IP address is 192.168.0.x, where x is calculated as:
X = (modulo 242 of the last 3 digits of the serial number) + 12
Example: A unit has a serial number of MJ3A16000405, the default IP address would be
192.168.0.175 (where 405 mod 242 = 163 + 12 = 175).
This is to ensure uniqueness of the default IP address for all 8 Series devices present on one
wireless network and it creates a usable address space from 192.168.0.12 to 192.168.0.253
for 8 Series devices.
NOTE
NOTE: From the remaining range of unicast addresses 192.168.0.1 to 192.168.0.253, at least two
are going to be used for the AP and a laptop installed with the EnerVista software, which
will be used to configure the 8 Series devices. The AP should be configured with the
address 192.168.0.1 and mask 255.255.255.0 and have DHCP enabled with a DHCP range
from 192.168.0.2 to 192.168.0.253. This allows laptops, iPads and any other devices to
connect to the local network without the need to statically configure their own IP address
and mask.

CHAPTER 2: COMMUNICATION PORTS WIFI
8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 2-3
WiFi GWY IP Address
The setting specifies the address of the access point AP which the 8 Series device uses for
communicating over WiFi.
WiFi Security
The setting enables WiFi security. If set to “None”, there is no security and all traffic is open.
By default WiFi Security is set to WPA2-PSK.
WiFi SSID
The SSID is the public name of a wireless network. All of the wireless devices on a WLAN
must use the same SSID in order to communicate with each other. The default for the SSID
is provided by the vendor with the shipment of any new 8-Series device. It is
recommended that the customer modifies this name as needed after initial startup, to
ensure unique SSIDs if several WLANs are configured.
NOTE
NOTE: SSID broadcast should be disabled on AP. This provides some extra protection by requiring
a user to know an SSID before the user can connect to the device and making it harder for
casual outsiders looking for wireless networks to find the device and attempt to connect.
WiFi WPA2 Passphrase
The WPA2 Passphrase is used for generating the encryption key. The same passphrase
must be set on AP and on all devices communicating on the same WLAN. The 8-Series
device supports a string of up to 14 printable ASCII characters. Internally a 256-bit key is
calculated by applying the PBKDF2 key derivation function to this passphrase, using the
SSID as the salt and 4096 iterations of HMAC-SHA1.
The 8-Series devices are configured with a default passphrase, which is provided by the
vendor with the shipment of any new 8-Series device.
When choosing a new passphrase, the password complexity rules of CyberSentry must be
used (see CyberSentry details in the relay Instruction manual).
This field is visible only if the security is set to WPA2-PSK.
NOTE
NOTE: Ideally the passphrase should be set through EnerVista and not directly from the Keypad,
where there are limitations in terms of space and types of characters supported. However,
for convenience, the key setting is available from the Keypad as well.
WiFi Status
A WiFi symbol is displayed in the caption area of the 8-Series product front panel. The
following table lists all possibilities for this icon:

USB
The USB parameters are as follows:
IP Address: 172.16.0.2
IP Mask: 255.255.255.0
IP Gateway: 172.16.0.1
FASTPATH: Whenever the device is rebooted, the USB cable needs to be unplugged and plugged in
again for proper communication to be established over USB.
FASTPATH: Connecting multiple 8 Series relays over USB to a single PC is not possible because in the
case of USB, the IP address of the device 172.16.0.2 is constant.
Using the Quick Connect Feature via the USB Port
From the EnerVista 8 Series Setup software the Quick Connect button can be used to
establish a fast connection through the front panel USB port of an 8 Series relay.
Before starting, verify that the standard USB cable is properly connected from the laptop
computer to the front panel USB port.
1. Verify that the latest version of the EnerVista 8 Series Setup software is installed

CHAPTER 2: COMMUNICATION PORTS ETHERNET PORTS
8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 2-7
PRT1 GWY ADDRESS
This setting sets the ports IPv4 GATEWAY address in standard IPv4 format.
This setting is only valid on port 1.
This setting is not present on port 4 and 5, which are available on the communications
card.
NOTE
NOTE: The communications card comes with the capability of setting a number of static routes
and one default route, which is used instead of default gateways.
Notes:
• The fiber optic ports support only 100 Mbps.
• Changes to the Ethernet communications settings take effect only after rebooting the
relay.
• All Ethernet ports have flex operands associated with them. A failure of one of the
Ethernet ports will trigger an event, a target message and the corresponding operand
set.
PRT4 OPERATION
Range: Independent, LLA, PRP
Default: Independent
This setting determines the mode of operation for ports 4 and 5: INDEPENDENT, LLA or
PRP.
INDEPENDENT operation: ports 4 and 5 operate independently with their own MAC and
IP address.
LLA operation: the operation of ports 4 and 5 are as follows:
Ports 4 and 5 use port 4’s MAC and IP address settings while port 5 is in standby mode in
that it does not actively communicate on the Ethernet network but monitors its link. If
Port 4 is active and the link loss problem is detected, communications is switched to Port
5 immediately. Port 5 is, in effect, acting as a redundant or backup link to the network
for port 4.
LLA (Link Loss Alert) is a proprietary feature supported by the 8 Series relay fiber optic
ports. When enabled on an 8 Series fiber optic port, this feature is able to detect a failure
of the fiber link. If port 4’s OPERATION is set to LLA, the detection of a link failure by this
feature triggers the transfer of communications from port 4 to port 5. If LLA is enabled
on a port with a non-fiber SFP, the target message “LLA not supported by Prt (4 or 5)” is
displayed on the keypad and an event is logged.
PRP (Parallel Redundancy Protocol): ports 4 and 5 use the same MAC address and
combine information at the link layer. It is intended to only be used if the two ports are
connected to separate parallel LAN’s. In this mode of operation both ports cannot be
connected to the same LAN. The receiving devices (8 Series relay ) process the first
frame received and discard the duplicate through a link redundancy entity (LRE) or
similar service that operates below layer 2. Aside from LRE, PRP uses conventional
Ethernet hardware but both ports must know they are in PRP. Ports of PRP devices
operating with the same Internet Protocol (IP) addresses for traffic that uses IP
Management protocols such as Address Resolution Protocol (ARP) must operate
correctly.
Duplicate Discard mode (only mode supported by the 8 Series). This is the normal
setting for PRP operation and once set it allows the sender LRE to append a six-octet
field that contains a sequence number, the Redundancy Control Trailer (RCT) to both
frames it sends. The receiver LRE uses the sequence number of the RCT and the source
MAC address to detect duplicates. It forwards only the first frame of a pair to its upper
layers.

Routing
When the configuration card is present, a default route and a maximum number of 6 static
routes can be configured. The default route is used as the last choice, if no other route
towards a given destination is found.
Path: Setpoints > Device > Communications > Routing > Default Route
GATEWAY ADDRESS
Range: Standard IPV4 unicast address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the gateway of the default route to be used by IP traffic sent from the
relay, if no other route towards a given IP destination is found.
This setting is available only if the communications card is present.
Path: Setpoints > Device > Communications > Routing > Static RT1 (2 to 6)
RT1 (2,3,4,5,6) DESTINATION
Range: Standard IPV4 network address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the destination IPv4 route. This setting is available only if the
communications card is present.
RT1 (2,3,4,5,6) MASK
Range: Standard IPV4 network mask format
Default: 255.0.0.0
This setting sets the IP mask associated with the route. This setting is available only if the
communications card is present.
RT1 (2,3,4,5,6) GATEWAY
Range: Standard IPV4 unicast address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the destination IP route. This setting is available only if the
communications card is present.
ADDING AND DELETING STATIC ROUTES
Defaults:
Rule #1.
By default, the value of the destination field is 127.0.0.1 for all static routes (1 to 6). This
is equivalent to saying that the static routes are not configured. When the destination
address is 127.0.0.1, the mask and gateway must also be kept as default values.Rule #2.
By default, the value of the default route gateway address is 127.0.0.1. This means the
default route is not configured.
Adding a route:
Rule #3.
Use any of the static network route entries numbered 1 to 6 to configure a static
network route. Once a route destination is configured for any of the entries 1 to 6, that
entry becomes a static route and it must meet all the rules listed in the following section
under “Important Notes”.
Rule #4.
To configure the default route, enter a default gateway address. A default gateway
address configured must be validated against Rule #5, the next rule.

CHAPTER 2: COMMUNICATION PORTS ETHERNET PORTS
8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 2-9
Deleting a route:
Rule #5.
Routes are deleted by replacing the route destination with the default address
(127.0.0.1). When deleting a route, the mask and gateway must also be put back to their
default values.
Rule #6.
The default route is deleted by replacing the default gateway with the default value
127.0.0.1.
Important Notes:
1. Host routes are not supported at present.
2. The route mask has IPv4 mask format. In binary this is a set of contiguous bits of 1
from left to right, followed by one or more contiguous bits of 0.
3. The route destination and mask must match.
4. Item #3, above, can be verified by checking that RtDestination & RtMask ==
RtDestination
5. This is an example of a good configuration: RtDestination= 10.1.1.0; Rt Mask=
255.255.255.0
6. This is an example of a bad configuration: RtDestination = 10.1.1.1; Rt Mask=
255.255.255.0
7. The route destination must not be a connected network.
8. The route gateway must be on a connected network. This rule applies to the gateway
address of the default route as well.
9. Item #8, above, can be verified by checking that:
RtGwy & Prt4Mask) == (Prt4IP & Prt4Mask) || (RtGwy & Prt5Mask) == (Prt5IP & Prt5Mask)
TARGETS
WRONG ROUTE CONFIG
Description: A route with mismatched destination and mask has been configured.
Message: “Wrong route configuration.
”What to do: Rectify the IP address and mask of the mis-configured route.
TOPOLOGY EXAMPLE
Figure 2-2: Topology Example
In the above figure: Topology Example, the 8 Series device is connected through the two
Ethernet ports available on the communications card.
• Port 4 (IP address 10.1.1.2) connects to LAN 10.1.1.0/24 and to the Internet through
Router1. Router 1 has an interface on 10.1.1.0/24 and the IP address of this interface is
10.1.1.1.

2-10 8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
STATUS CHAPTER 2: COMMUNICATION PORTS
• Port 5 (IP address 10.1.2.2) connects to LAN 10.1.2.0/24 and to EnerVista setup
program through Router 2. Router 2 has an interface on 10.1.2.0/24 and the IP
address of this interface is 10.1.2.1.
Configuration
Network addresses:
PRT54IP ADDRESS = 10.1.1.2PRT4 SUBNET IP MASK = 255.255.255.0PRT5 IP ADDRESS =
10.1.2.2PRT5 SUBNET IP MASK = 255.255.255.0
Routing Settings:
IPV4 DEFAULT ROUTE: GATEWAY ADDRESS = 10.1.1.1
STATIC NETWORK ROUTE 1:
– RT1 DESTINATION = 10.1.3.0/24RT1 NET MASK = 255.255.255.0RT1 GATEWAY =
10.1.2.1
Behavior: One static network route was added to the destination 10.1.3.0/24, where a
laptop running EnerVista is located. This static route uses a different gateway (10.1.2.1)
than the default route. This gateway is the address of Router 2, which is “aware” of
destination 10.1.3.0 and is able to route packets coming from the 8 Series device and
destined to EnerVista.
Status
TCP Connections Status
These values specify the maximum and the remaining number of TCP connections still
available for each protocol. Depending on the order code, some protocols may be hidden.
Each time a connection is used, the remaining number of connections decrements. When
a connection is released, the remaining number of connections increments. If no
connection is made over the specific protocol, the number remaining equals the maximum
number available for the specific protocol.
For example, the maximum number of Modbus TCP connections is 5. Once an EnerVista
session is opened on a computer connected to the 8series over Ethernet, the Modbus TCP
status shows 4. If the EnerVista application is closed, the Modbus TCP status shows 5.
The following are the Maximum TCP connections per protocols for the “SE”
communications order code option:
* With USB or WiFi connections, this number decreases as follows:
• 1 USB or 1 WiFi connection: Modbus TCP - Maximum = 2
• 1 USB and 1 WiFi connection: Modbus TCP - Maximum = 1
The following are the Maximum TCP connections per protocols for the Advanced
communications order code options:
Modbus TCP - Maximum 3*
DNP TCP - Maximum 2 (Depends on number of configured channels)
