Chapter 2: Modbus communication
Modbus communication
This chapter outlines the Modbus protocol. Use the memory map at the end of the chapter
when designing a client to access the D90Plus device using Modbus.
Modbus protocol overview
Modbus is a standard protocol for communication among devices. Modbus is available via
serial links (Modbus remote terminal unit, or RTU) or Ethernet (Modbus/TCP). The D90Plus
supports Modbus RTU.
The D90Plus acts as a slave device. It listens and responds to requests issued by a master
computer. It never initiates communications.
The following description is intended for users who want to develop their own
communication drivers and applies to the serial Modbus RTU protocol.
Physical layer
The Modbus RTU protocol is hardware-independent, allowing the physical layer to be any
standard hardware configuration. The D90Plus includes a front USB port and rear
communications ports that can be configured as RS485, 10/100Base-T, or 100Base-F.
Data flow is auto-negotiated to half-duplex or full-duplex in all configurations.
Each data byte is transmitted in an asynchronous format consisting of one start bit, eight
data bits, one stop bit, and possibly one parity bit. This produces a 10 or 11-bit data frame.
This can be important for transmission through modems at high bit rates (11 bit data
frames are not supported by many modems at baud rates greater than 300).
The baud rate and parity are independently programmable for each communications port.
Baud rates of 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 33600, 38400, 57600, or
115200 bps are available. Even, odd, and no parity are available.
The master device in any system must know the address of the slave device for
communication. The relay does not act on a request from a master if the address in the
request does not match the relay slave address, unless the address is the broadcast
address.

PLUS LINE DISTANCE PROTECTION SYSTEM – COMMUNICATIONS GUIDE
MODBUS PROTOCOL OVERVIEW CHAPTER 2: MODBUS COMMUNICATION
Data link layer
Communication takes place in packets that are groups of asynchronously framed byte
data. The master transmits a packet to the slave and the slave responds with a packet. The
end of a packet is marked by dead-time on the communications line. The table shows the
general format for both transmit and receive packets.
Table 1: Modbus packet format
The slave address indicates the address of the slave device intended to receive the packet
sent by the master and to perform the required action. Each slave device on a
communications bus must have a unique address to prevent bus contention. The D90Plus
slave address is programmable from 1 to 254. Only the slave addressed responds to a
packet that starts with its address. Note that the faceplate USB port is an exception to this
rule; it acts on a message containing any slave address.
A master transmit packet with slave address 0 indicates a broadcast command. All slaves
on the communication link take action based on the packet, but none respond to the
master. Broadcast mode is only recognized when associated with function code 05h. For
any other function code, a packet with broadcast mode slave address 0 is ignored.
The function code tells the slave which action to perform. An exception response from the
slave is indicated by setting the high order bit of the function code in the response packet.
The data format is a variable number of bytes depending on the function code. This can
include actual values or addresses sent by the master to the slave or by the slave to the
master.
The CRC is a two-byte error checking code. Modbus RTU includes a 16-bit cyclic
redundancy check (CRC-16) with every packet. This is an industry standard method used
for error detection. If a Modbus slave device receives a packet in which an error is
indicated by the CRC, the slave device does not act upon or respond to the packet. This
prevents erroneous operations.
A packet is terminated when no data is received for a period of 3.5 byte transmission times
(about 15 ms at 2400 bps, 2 ms at 19200 bps, and 300 µs at 115200 bps). Consequently,
the transmitting device must not allow gaps between bytes longer than this interval. Once
the dead time has expired without a new byte transmission, all slaves start listening for a
new packet from the master except for the addressed slave.
CRC-16 algorithm
The 16-bit cyclic redundancy check (CRC-16) algorithm treats the entire data stream (data
bits only; start, stop, and parity ignored) as one continuous binary number. This number is
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 packet, MSByte first. The
resulting packet including CRC, when divided by the same polynomial at the receiver, gives
a zero remainder if no transmission errors have occurred. This algorithm requires the
characteristic polynomial to be reverse-bit ordered. The most significant bit of the
characteristic polynomial is dropped, since it does not affect the value of the remainder.
A C programming language implementation of the CRC algorithm is provided upon
request. The algorithm is as follows:
Description Size
Slave address 1 byte
Function code 1 byte
Data 1 or more bytes
CRC 2 bytes
Dead time 3.5 bytes transmission time

Modbus function codes
While the Modbus protocol defines function codes from 1 to 127, only a small subset
generally is needed. The table outlines the functions supported by the D90Plus.
Table 2: Modbus function codes supported
Read actual values
The read actual values function codes (04h) allow the master to read one or more
consecutive data registers (actual values) from a D90Plus device. Data registers are always
16-bit (two-byte) values transmitted with the high-order byte first. The maximum number
of registers that can be read in a single packet is 125. See the Modbus Memory Map table
for details on the data registers.

Exception responses
Operation errors usually occur because of illegal data in a packet. These errors result in an
exception response from the slave. The slave detecting one of these errors sends a
response packet to the master with the high order bit of the function code set to 1.
The following tables illustrate the format of the master and slave packets for an exception
response. The example shows a master device sending the unsupported function code
39h to slave device 11.

MODBUS SETTINGS CHAPTER 2: MODBUS COMMUNICATION
Modbus settings
This section outlines configuration settings from the instruction manual.
Modbus protocol
The Modbus server can simultaneously support one client over serial RS485 and four
clients over Ethernet. The server is capable of reporting any indication or measurement
and operating any output present in the device. A user-configurable input and output map
also is implemented.
The D90Plus operates as a Modbus slave device only.
In the EnerVista software, select the Settings > Communications > Modbus > Protocol
menu to open the Modbus protocol configuration window.
Figure 1: Modbus protocol configuration settings
The following settings are available.
Modbus Slave Address
Range: 1 to 254 in steps of 1
Default: 254
This setting specifies the Modbus slave address for the D90Plus. Each device must have a
unique address from 1 to 254. Address 0 and addresses from 248 and up are reserved by
the Modbus protocol specification, and so their use here is not recommended. Address 0
is the broadcast address to which all Modbus slave devices listen. Addresses do not have
to be sequential, but no two devices can have the same address or conflicts resulting in
errors occur. Generally, starting at 1, set each device added to the link to the next higher
address.
Modbus TCP Port Number
Range: 1 to 65535 in steps of 1
Default: 502
Modbus over TCP/IP can also be used on any of the Ethernet ports. This setting specifies
the Modbus TCP port number for Ethernet communications. Power to the D90Plus must
be cycled for changes to this setting to take effect.
NOTE
Do not set more than one protocol to the same TCP/UDP port number, as this results in
unreliable operation of those protocols.
Modbus user map
The Modbus user map provides read-only access for up to 256 registers. To obtain a
memory map value, enter the address in the Parameter field (this value must be converted
from hexadecimal to decimal format). The corresponding value (if programmed) displays in
the Value field. A value of “0” in subsequent register Address lines automatically returns

CHAPTER 2: MODBUS COMMUNICATION MODBUS MEMORY MAP
D90PLUS LINE DISTANCE PROTECTION SYSTEM – COMMUNICATIONS GUIDE 9
values for the previous Address lines incremented by 1. An address value of “0” in the initial
register means "none" and values of “0” displays for all registers. Different address values
can be entered as required in any of the register positions.
Select the Settings > Communications > Modbus > User Map menu to open the Modbus
user map configuration window.
Figure 2: Modbus user map configuration settings
The following settings are available for each of the 256 registers.
Modbus Type
Range: None, Settings, Actuals
Default: None
This setting indicates if the Modbus user map address represents a setting or an actual
value.
Parameter
Range: Modbus memory map address in decimal representation
Default: 0
This setting represents the value of the programmed Modbus memory map address.
Modbus memory map
The table outlines the user-accessible features of the D90Plus Modbus memory map. Those
present depend on order code.
The memory map is also viewable in a web browser. In the browser, enter the IP address of
the D90Plus.
The memory map is also provided as a .ini file. See the SYS_ModbusMemoryMap.ini file
provided on the CD.
See the Modbus data formats section that follows for details on the Format codes for each
register, for example F001.
