SR3 Series Protective Relay Platform
Chapter 1: Introduction
GE
Grid Solutions
Introduction
The Multilin 3 Series protective relay platform includes three different relays, the 350, 345,
and 339. Information in this manual applies to all 3 Series relays unless otherwise
indicated.
The 350 is a microprocessor-based relay for primary and backup overcurrent protection of
medium and low voltage distribution feeders. The relay is also suitable for providing
overcurrent and backup protection for small and medium size motors, transformers,
generators, and distribution bus-bars.
The 345 is a microprocessor-based relay for primary and backup protection of small to
medium size distribution transformers. The relay provides advanced algorithms for
automatic magnitude and phase compensation for more than twenty types of two-
winding transformers, good sensitivity for the detection of winding ground faults, and the
flexibility to set any of the phase, ground, neutral and negative sequence currents
overcurrent elements.
The 339 Motor Protection System is a microprocessor based relay providing suitable
protection of medium voltage motors. The basic protection functions of this relay include
motor thermal model, time-delayed and instantaneous overcurrent, ground overcurrent
and sensitive ground overcurrent protection. Additional control features such as logic
control are available for applications that require additional motor control functionality.
Communications interfaces
Each 3 Series relay has three communications interfaces. These can be used
simultaneously:
• RS485
•USB
•Ethernet

COMMUNICATIONS INTERFACES CHAPTER 1: INTRODUCTION

SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 2-1
SR3 Series Protective Relay Platform
Chapter 2: RS485 interface
GE
Grid Solutions
RS485 interface
The hardware or electrical interface in the 3 Series relay is two-wire RS485. In a two-wire
link, data is transmitted and received over the same two wires. Although RS485 two wire
communication is bi-directional, the data is never transmitted and received at the same
time. This means that the data flow is half duplex.
NOTE
NOTE: Polarity is important in RS485 communications. The '+' (positive) terminals of every device
must be connected together.
Electrical Interface
RS485 lines should be connected in a daisy chain configuration with terminating networks
installed at each end of the link (i.e. at the master end and at the slave farthest from the
master). The terminating network should consist of a 120 W resistor in series with a 1 nF
ceramic capacitor when used with Belden 9841 RS485 wire. Shielded wire should always
be used to minimize noise. The shield should be connected to all of the 3 Series relay s as
well as the master, then grounded at one location only. This keeps the ground potential at
the same level for all of the devices on the serial link.

2-2 SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
MODBUS PROTOCOL CHAPTER 2: RS485 INTERFACE
MODBUS Protocol
The 3 Series relay implements a subset of the Modicon Modbus RTU serial communication
standard. The Modbus protocol is hardware-independent. That is, the physical layer can be
any of a variety of standard hardware configurations. This includes USB, RS485, fibre
optics, etc. Modbus is a single master / multiple slave type of protocol suitable for a multi-
drop configuration.
The 3 Series relay is always a Modbus slave. It can not be programmed as a Modbus
master. Computers or PLCs are commonly programmed as masters.
Both monitoring and control are possible using read and write register commands. Other
commands are supported to provide additional functions.
The Modbus protocol has the following characteristics.
•Address:1to254
• Supported Modbus function codes: 1H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 10H, 42H, 43H
For details see MODBUS Functions.
Data Frame Format and Data Rate
One data frame of an asynchronous transmission to or from a 3 Series relay typically
consists of 1 start bit, 8 data bits, and 1 stop bit. This produces a 10 bit data frame. This is
important for transmission through modems at high bit rates.
Modbus protocol can be implemented at any standard communication speed. The 3 Series
relay supports operation at 9600, 19200, 38400, 57600, and 115200 baud.
NOTE
NOTE: The USB interface will support only 115200 baud.
Data Packet Format
A complete request/response sequence consists of the following bytes (transmitted as
separate data frames):
Master Request Transmission:
SLAVE ADDRESS: 1 byte
FUNCTION CODE: 1 byte
DATA: variable number of bytes depending on FUNCTION CODE
CRC: 2 bytes
Slave Response Transmission:
SLAVE ADDRESS: 1 byte
FUNCTION CODE: 1 byte
DATA: variable number of bytes depending on FUNCTION CODE
CRC: 2 bytes
SLAVE ADDRESS: This is the first byte of every transmission. This byte represents the user-
assigned address of the slave device that is to receive the message sent by the master.
Each slave device must be assigned a unique address and only the addressed slave will
respond to a transmission that starts with its address. In a master request transmission the
SLAVE ADDRESS represents the address of the slave to which the request is being sent. In a
slave response transmission the SLAVE ADDRESS represents the address of the slave that is
sending the response.
FUNCTION CODE: This is the second byte of every transmission. Modbus defines function
codes of 1 to 127.

CHAPTER 2: RS485 INTERFACE MODBUS PROTOCOL
SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE 2-3
DATA: This will be a variable number of bytes depending on the FUNCTION CODE. This may
be Actual Values, Setpoints, or addresses sent by the master to the slave or by the slave to
the master.
CRC: This is a two byte error checking code.
Error Checking
The RTU version of Modbus includes a two byte CRC-16 (16 bit cyclic redundancy check)
with every transmission. The CRC-16 algorithm essentially treats the entire data stream
(data bits only; start, stop and parity ignored) as one continuous binary number. This
number is first shifted left 16 bits and then divided by a characteristic polynomial
(11000000000000101B). The 16 bit remainder of the division is appended to the end of the
transmission, MSByte first. The resulting message including CRC, when divided by the
same polynomial at the receiver will give a zero remainder if no transmission errors have
occurred.
If a 3 Series relay Modbus slave device receives a transmission in which an error is
indicated by the CRC-16 calculation, the slave device will not respond to the transmission.
A CRC-16 error indicates than one or more bytes of the transmission were received
incorrectly and thus the entire transmission should be ignored in order to avoid the 3
Series relay performing any incorrect operation.
The CRC-16 calculation is an industry standard method used for error detection. An
algorithm is included here to assist programmers in situations where no standard CRC-16
calculation routines are available.
CRC-16 Algorithm
Once the following algorithm is complete, the working register “A” will contain the CRC
value to be transmitted. Note that this algorithm requires the characteristic polynomial to
be reverse bit ordered. The MSBit of the characteristic polynomial is dropped since it does
not affect the value of the remainder. The following symbols are used in the algorithm:
—>: data transfer
A: 16 bit working register
AL: low order byte of A
AH: high order byte of A
CRC: 16 bit CRC-16 value
i, j: loop counters
(+): logical exclusive or operator
Di: i-th data byte (i = 0 to N-1)
G: 16 bit characteristic polynomial = 1010000000000001 with MSbit dropped and bit order
reversed
shr(x): shift right (the LSbit of the low order byte of x shifts into a carry flag, a '0' is shifted
into the MSbit of the high order byte of x, all other bits shift right one location
The algorithm is:
1. FFFF hex —> A
2. 0 —> i
3. 0 —> j

2-4 SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE

4. Di (+) AL —> AL
5. j+1 —> j
6. shr(A)
7. is there a carry? No: go to 8. Yes: G (+) A —> A
8. is j = 8? No: go to 5. Yes: go to 9.
9. i+1 —> i
10. is i = N? No: go to 3. Yes: go to 11.
11. A —> CRC
Timing
Data packet synchronization is maintained by timing constraints. The receiving device
must measure the time between the reception of characters. If 3.5 character times elapse
without a new character or completion of the packet, then the communication link must
be reset (i.e. all slaves start listening for a new transmission from the master). Thus at
115200 baud a delay of greater than 3.5 x 1 / 115200 x 10 x = 0.3 ms will cause the
communication link to be reset.
3 Series supported functions
The following functions are supported by the 3 Series relay :
• FUNCTION CODE 03H - Read Setpoints
• FUNCTION CODE 04H - Read Actual Values
• FUNCTION CODE 05H - Execute Operation
• FUNCTION CODE 06H - Store Single Setpoint
• FUNCTION CODE 07H - Read Device Status
• FUNCTION CODE 08H - Loopback Test

that is, the appropriate Virtual Input or Coil is put into the “On” state. The On/Off times and Count
value are ignored. “Pulse Off” and “Latch Off” operations put the appropriate Virtual Input or Coil into
the “Off” state. “Trip” and “Close” operations both put the appropriate Virtual Input or coil into the
“On” state if a paired mapping is set, otherwise “Trip” will put into “Off” and “Close” will put into “On”.
