Chapter 1: Introduction
GE
Digital Energy
Introduction
The 869 Motor Protection, Control and Management System 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.
Communications
The 869 has 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, 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 and IEEE 1588 Precision Time Protocol.
The communications CPU also supports Modbus TCP, IEC 104, DNP TCP, TFTP, SFTP, and
SNTP protocol.

2-2 869 MOTOR PROTECTION SYSTEM – 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

CHAPTER 2: COMMUNICATION PORTS WIFI
869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE 2-3
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
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 192.168.0.11, 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 192.168.0.11. This allows laptops, iPads and any other devices
(Android, iPhone) to connect to the local network without the need to statically configure
their own IP address and mask.
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.

2-4 869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE
WIFI CHAPTER 2: COMMUNICATION PORTS
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 869 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:
WiFi Events
NOTE
NOTE: If the relay is in service mode and the settings are default a minor error is triggered.

Network Settings Menu
The following are the network settings menu of the 869 to accommodate the features of
the 869 product. If the communications card is installed network port 1 is no longer
available. When using more than one Ethernet port, configure each to belong to a different
network or subnet using the IP addresses and mask, else communication becomes
unpredictable when more than one port is configured to the same subnet.
NOTE
NOTE: The softkeys and Down/Up key can be used to enter an IP address. When entering an IP
address you must press the “Back” key first to switch between softkey mode and the
Down/Up key mode.
NETWORK 1, 4, 5, PRT1(4,5) IP ADDRESS
Range: Standard IPV4 Address format
Default: 169.254.3.3 (Port 1)
Default: 127.0.0.1 (Port 4, 5)
The setting sets the port’s IPV4 address in standard IPV4 format.
NOTE
NOTE: The setting is valid on port 1 if the optional communications card is not present.
The setting is valid on port 5 if port 4’s OPERATION is set to INDEPENDENT.
PRT1(4,5) SUBNET IP MASK
Range: Standard IPV4 mask format
Default: 255.255.255.0 (Port 1)
Default: 0.0.0.0 (Port 4, 5)
This setting specifies the IPv4 mask associated with the corresponding port IP address.
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.

2-8 869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE
ETHERNET PORTS CHAPTER 2: COMMUNICATION PORTS
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 (SR relays) 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.

CHAPTER 2: COMMUNICATION PORTS ETHERNET PORTS
869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE 2-9
Figure 2-2: Device Display for Routing Hierarchy
SETTINGS
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.
STATIC ROUTE 1 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.
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.

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.

The 869 is capable of receiving a time reference from several time sources in addition to its
own internal clock for the purpose of time-stamping events, transient recorders and other
occurrences within the relay. The accuracy of the time stamp is based on the time
reference that is used. The 869 supports an internal clock, SNTP, IRIG-B, and PTP IEEE 1588
as potential time references.
If two or more time sources are available, the time source with the higher priority shown in
Time Sources table is used where 1 is considered to be the highest priority. Please note
that the time source priority of PTP and IRIG-B can be swapped. If both PTP and IRIG-B are
available to the 869, by default the 869 clock syncs to PTP over IRIG-B. If PTP is not
available the 869 CPU syncs the internal clock to IRIG-B.

* The priority of IRIG-B and PTP can be swapped.
FASTPATH: Synchronization by IEC103, DNP, Modbus and IEC104 is not going to be issued if there is a
sync source from IRIG-B, SNTP or PTP.

The RTC Sync Source actual value is the time synchronizing source the relay is using at
present. Possible sources are: Port 4 PTP Clock, Port 5 PTP Clock, IRIG-B, SNTP and None.
Grandmaster ID is the grandmaster Identity code being received from the present PTP
grandmaster, if any. When the relay is not using any PTP grandmaster, this actual value is
zero. The grandmaster Identity code is specified by PTP to be globally unique, so one can
always know which clock is grandmaster in a system with multiple grandmaster-capable
clocks.
RTC Accuracy is the estimated maximum time difference at present in the Real Time Clock
(RTC), considering the quality information imbedded in the received time signal, how long
the relay has had to lock to the time source, and in the case of time signal interruptions,
the length of the interruption. The value 999,999,999 indicates that the magnitude of the
estimated difference is one second or more, or that the difference cannot be estimated.
Port 4 (5) PTP State is the present state of the port’s PTP clock. The PTP clock state is:
•DISABLED
If the port’s function setting is Disabled
•NOSIGNAL
If enabled but no signal from an active master has been found and selected
•CALIBRATING
If an active master has been selected but lock is not at present established
•SYNCH’D(NOPDELAY)
If the port is synchronized, but the peer delay mechanism is non-operational
•SYNCHRONIZED
If the port is synchronized
