Modbus Protocol 1 Protocol Description
1 Protocol Description
This document describes the protocol for command control and data exchange
between the UPS monitoring module and the host computer.
The protocol supports the following functions:
1. The host computer sends a read command to obtain relevant UPS
information.
2. The host computer sends a write command to set parameters or control
operations.
The host computer serves as the master device in the communication process,
which exchanges information through a question and answer approach. A variety
of information and parameters of the slave device use the destination register as
the storage address, then the master device can access the destination register to
execute the read and write commands. The protocol supports a master device
networked with multiple slave devices. Slave devices are distinguished by
addresses, and the address is set in the range from 1 to 254. Different slave nodes
correspond to different addresses. The slave nodes connecting to the same
communication bus cannot have the same address.

Modbus Protocol 2 Definition
2 Definition
Master node: host computer, which is responsible for communication with slave
nodes.
Slave node: UPS monitoring module, which collects information from the UPS
power module.
RS485: a serial communication standard, which can support half-duplex serial
short-range communication.
Read command: The master node sends a read command to the slave node,
instructing the slave node to return relevant register contents.
Write command: The master node packs parameters and sends them to the slave
node to configure corresponding parameters.
Register address: Each signal or parameter of the slave device corresponds to a
register address, which the master device accesses to obtain relevant information
or configure relevant parameters.
Slave node address: The slave node address is set in the range from 1 to 254.

● When connecting a parallel system to the network management system (NMS), use an
active RS485/232 converter with the isolation function. A hot-swappable RS485/232
converter is not recommended.
● The RS485 bus of each device is equipped with an independent 120-ohm build-out
resistor. It is recommended that multiple devices not be connected in parallel using
RS485 communications cables.If parallel connection is required, ensure that the
maximum number of parallel devices is 4 or an RS485 repeater be used.
3.2 MODBUS-TCP
3.2.1 Electrical Standard
The slave nodes communicate with the master node through the FE port over IP.
Information is transmitted in TCP transmission mode of the Modbus protocol over
port 502. A maximum of two sockets can be connected.
You can enable or disable communication data encryption by choosing Param.
Settings > Advanced Param. > ModbusTCP encryption on the WebUI or
Settings > Advanced Param. > ModbusTCP encryption on the LCD.
3.2.2 Differences Between TCP and RTU
Modbus-TCP is a Modbus protocol carried by TCP. The difference is that MBAP
packet header is added and CRC of the Modbus frame is removed.

Modbus Protocol 3 Physical Interface
When Modbus is applied to TCP/IP, a dedicated MBAP packet header (Modbus
Application Protocol packet header) will be used to identify Modbus application
data unit (ADU). The Modbus-TCP data frame format is defined as follows:
The MBAP packet header (MBAP is short for Modbus Application Protocol) is
divided into four domains which include seven bytes in total.

After the slave nodes are powered on or reset and stably run, they respond to the
read or write command sent from the master node. After the slave nodes receive
related commands, the slave nodes can return requested information to the
master node under normal conditions, or return specific error codes corresponding
to the error types under abnormal conditions.

5.5.2 Error Code Definitions
Table 5-10 Error codes returned by NEs
Code Name Definition Network Process
0x01 ILLEGAL The function code received in the N/A
FUNCTION query is not an allowable action for
the server. This may be because the
function code is only applicable to
newer devices, and was not
implemented in the unit selected. It
could also indicate that the server is
in the wrong state to process a
request of this type, for example
because it is not configured and is
being asked to return register
values.
0x02 ILLEGAL DATA The data address received in the N/A
ADDRESS query is not an allowable address
for the server. More specifically, the
combination of reference number
and transfer length is invalid. For a
controller with 100 registers, the
PDU addresses the first register as 0,
and the last one as 99. If a request
is submitted with a starting register
address of 96 and a quantity of
registers of 4, then this request will
successfully operate (address-wise
at least) on registers 96, 97, 98, 99.
If a request is submitted with a
starting register address of 96 and a
quantity of registers of 5, then this
request will fail with Exception Code
0x02 "Illegal Data Address" since it
attempts to operate on registers 96,
97, 98, 99 and 100, and there is no
register with address 100.
0x03 ILLEGAL DATA A server or slave node receives N/A
VALUE illegal data during a query, which
indicates a fault in the remaining
structure of a combination request,
for example, the implicit length is
incorrect. This does not mean that a
register stores a value not expected
by an application because the
Modbus protocol does not
understand the meaning of a
special value in a register.

When the registers of IBOX analog and alarm signals are accessed, the address
should be the IBOX logic address configured on the interface.
For example, if the IBOX logic start address is 50, then the IBOX1 address is 50,
the IBOX2 address is 51, and the like.

The battery string data packs need to be offset based on the battery string numbers. The
rule is similar to that for obtaining the analog data of single batteries. For example, 0xA050
indicates the SOH data pack of the first battery string, and 0xA051 indicates the SOH data
pack of the second battery string.

Modbus Protocol 1 Protocol Description
1 Protocol Description
This document describes the protocol for command control and data exchange
between the UPS monitoring module and the host computer.
The protocol supports the following functions:
1. The host computer sends a read command to obtain relevant UPS
information.
2. The host computer sends a write command to set parameters or control
operations.
The host computer serves as the master device in the communication process,
which exchanges information through a question and answer approach. A variety
of information and parameters of the slave device use the destination register as
the storage address, then the master device can access the destination register to
execute the read and write commands. The protocol supports a master device
networked with multiple slave devices. Slave devices are distinguished by
addresses, and the address is set in the range from 1 to 254. Different slave nodes
correspond to different addresses. The slave nodes connecting to the same
communication bus cannot have the same address.

Modbus Protocol 2 Definition
2 Definition
Master node: host computer, which is responsible for communication with slave
nodes.
Slave node: UPS monitoring module, which collects information from the UPS
power module.
RS485: a serial communication standard, which can support half-duplex serial
short-range communication.
Read command: The master node sends a read command to the slave node,
instructing the slave node to return relevant register contents.
Write command: The master node packs parameters and sends them to the slave
node to configure corresponding parameters.
Register address: Each signal or parameter of the slave device corresponds to a
register address, which the master device accesses to obtain relevant information
or configure relevant parameters.
Slave node address: The slave node address is set in the range from 1 to 254.

3.1 MODBUS-RTU
3.1.1 Electrical Standard
The slave node communicates with the master node over the RS485 serial port.
Information transmission modes:
1. Information can be transmitted in RTU mode of the Modbus.
2. Character information can be transmitted in asynchronous mode using the
format of one start bit, eight data bits, and one stop bit (totally 10 bits).
3.1.2 Data Transmission Rate
The baud rate is set to 9600 bit/s by default and can be changed to 19200 bit/s, or
115200 bit/s.

● When connecting a parallel system to the network management system (NMS), use an
active RS485/232 converter with the isolation function. A hot-swappable RS485/232
converter is not recommended.
● The RS485 bus of each device is equipped with an independent 120-ohm build-out
resistor. It is recommended that multiple devices not be connected in parallel using
RS485 communications cables.If parallel connection is required, ensure that the
maximum number of parallel devices is 4 or an RS485 repeater be used.
3.2 MODBUS-TCP
3.2.1 Electrical Standard
The slave nodes communicate with the master node through the FE port over IP.
Information is transmitted in TCP transmission mode of the Modbus protocol over
port 502. A maximum of two sockets can be connected.
You can enable or disable communication data encryption by choosing Param.
Settings > Advanced Param. > ModbusTCP encryption on the WebUI or
Settings > Advanced Param. > ModbusTCP encryption on the LCD.
3.2.2 Differences Between TCP and RTU
Modbus-TCP is a Modbus protocol carried by TCP. The difference is that MBAP
packet header is added and CRC of the Modbus frame is removed.

Modbus Protocol 3 Physical Interface
When Modbus is applied to TCP/IP, a dedicated MBAP packet header (Modbus
Application Protocol packet header) will be used to identify Modbus application
data unit (ADU). The Modbus-TCP data frame format is defined as follows:
The MBAP packet header (MBAP is short for Modbus Application Protocol) is
divided into four domains which include seven bytes in total.

After the slave nodes are powered on or reset and stably run, they respond to the
read or write command sent from the master node. After the slave nodes receive
related commands, the slave nodes can return requested information to the
master node under normal conditions, or return specific error codes corresponding
to the error types under abnormal conditions.

5.5.2 Error Code Definitions
Table 5-10 Error codes returned by NEs
Code Name Definition Network Process
0x01 ILLEGAL The function code received in the N/A
FUNCTION query is not an allowable action for
the server. This may be because the
function code is only applicable to
newer devices, and was not
implemented in the unit selected. It
could also indicate that the server is
in the wrong state to process a
request of this type, for example
because it is not configured and is
being asked to return register
values.
0x02 ILLEGAL DATA The data address received in the N/A
ADDRESS query is not an allowable address
for the server. More specifically, the
combination of reference number
and transfer length is invalid. For a
controller with 100 registers, the
PDU addresses the first register as 0,
and the last one as 99. If a request
is submitted with a starting register
address of 96 and a quantity of
registers of 4, then this request will
successfully operate (address-wise
at least) on registers 96, 97, 98, 99.
If a request is submitted with a
starting register address of 96 and a
quantity of registers of 5, then this
request will fail with Exception Code
0x02 "Illegal Data Address" since it
attempts to operate on registers 96,
97, 98, 99 and 100, and there is no
register with address 100.
0x03 ILLEGAL DATA A server or slave node receives N/A
VALUE illegal data during a query, which
indicates a fault in the remaining
structure of a combination request,
for example, the implicit length is
incorrect. This does not mean that a
register stores a value not expected
by an application because the
Modbus protocol does not
understand the meaning of a
special value in a register.
