local mode and are influenced by the protection. If the protection blocks the tap
changer, the controller stops automatic control.
Overvoltage and undervoltage are protection and are not limited by tidal fixed
forward, fixed reverse, ring, or hybrid application scenarios, but because they are
closely related to voltage thresholds, some of their characteristic descriptions are
also listed here. Relationship of automation to application scenarios and currents.
Figure 4-2 Relationship between application scenarios and tide direction

The region is determined using the direction and magnitude of the current and
voltage. The magnitude is determined by 50REVP (reverse), 50FWDP (forward). The
direction of the tide is indicated by the reverse tide lamp.
4.2 LDC control functions
LDC is only applied during normal regulation. When the LDC function is enabled,
the target voltage is the voltage at a certain distance point after the measurement
point, which can be calculated using the measurement point voltage, the current and
the impedance between to the distance point. The fast setback is still based on the
voltage at the measurement point.
13
Figure 4-3 Schematic of target voltage for LDC function
Figure 4-4 Vector operation diagram

The vector operation is performed in single-phase, with a fixed positive current
as an example. if the target voltage VL is a line voltage, it should be converted to a
phase voltage and then calculated. il should also be a phase current. r and x are the
corresponding impedance and inductive reactance, and the values are entered
directly.
14
Figure 4-5 Illustration of LDC inactivity range

In order to avoid mutual oscillation between the fast setback control and the
LDC control, the LDC regulation inactivity range is established. When the LDC control
needs to boost, it needs to detect whether the target voltage is in the LDC boost
inactivity range area; when the LDC control needs to buck, it also needs to detect
whether the target voltage is in the LDC buck inactivity range area; the size of this
area is specified by the LDC inactivity range value.

Chapter 2 ModBus Protocol
24
1. Brief description of Modbus protocol
The controllers use the MODBUS-RTU communication protocol, which defines in
detail the data sequences and checksums that are necessary for data exchange.The
MODBUS protocol uses a master-slave answer connection (half-duplex) on one
communication line, where first the master computer (host) sends a signal to
address a unique controller (slave), and then the addressed controller sends a The
answer signal from the addressed controller is then transmitted to the master in the
opposite direction.
transmission method
A transmission method is a series of independent data structures within a data
frame and a limited set of rules used to transmit the data, and the following defines
the transmission methods that are compatible with the MODBUS protocol RTU
method.
Binary encoding (Coding System) 8 bits
Start bit 1 bit
Data bits 8 bits
Parity No parity
Stop bit (Stop bit) 1 bit
Error checking CRC (Cyclic Redundancy Check)
agreements
When the data frame arrives at the terminal device, the device removes the
"envelope" (data header) of the data frame, reads the data, and if there are no
errors, performs the task for which the data was requested, then it adds the data it
generated to the obtained "envelope" and returns the data frame back to the sender.
The returned response data contains the following: the address of the terminal slave
(Address), the command that was executed (Function), the requested data
generated by the execution of the command (Data), and a check code. There will be
no successful response to any error.
Data frame format

Address Function Data Check
8-Bits 8-Bits N x 8-Bits 16-Bits
Address field
The address field is at the beginning of the frame and consists of one byte (8-bit
binary code), decimal 0 to 247.
The address field identifies the address of the user-specified terminal device that will
receive data from the host to which it is connected. Each terminal device's address
must be unique, and only the terminal addressed will respond to a query containing
that address. When a terminal sends back a response, the slave address data in the
response tells the host which terminal is communicating with it.
Function domain
25
The function field codes tell the terminal being addressed what function to
perform. The function codes used by this terminal, and their meaning and function.
code significance behaviour

03 read register Get the current binary value of one or more
registers
05 Control order Execution of control commands
execution
16 Preset multi register Set binary values to a series of multiple registers
Data field
The data field contains data that the terminal needs to perform a specific function or
that the terminal sends up in response to a command. The content of this data may
be numeric values, parametric addresses, or set values. For example, the function
field code tells the terminal to read a register, while the data field needs to indicate
which register to start from and how many data to read, with the embedded address
and data varying depending on the type and content between slaves.
Error Check field

This field allows hosts and terminals to check for errors during transmission.
Sometimes, due to electrical noise and other interference, a set of data may be
changed on the line as it travels from one device to another, and error checking
improves the security and efficiency of the system by ensuring that the host or
terminal does not respond to data that has changed during transmission, using the
16-bit cyclic redundancy method (CRC16).

2.2 Control command output (function code 05)

When a control command is issued, FF00H needs to be written to the corresponding
control command address, and the slave receives this data to execute the command
at the corresponding address. When any other data is written, the command cannot
be executed.
The following example is a request to slave 10 to execute the command
corresponding to address 0000H.
Addr Fun DO addr hi DO addr lo Value hi Value lo CRC16 lo CRC16 hi
0AH 05H 00H 00H FFH 00H 8DH 41H
The normal response to a command request is to control the data received back
after the command has been executed.
Addr Fun DO addr hi DO addr lo Value hi Value lo CRC16 CRC16
lo hi
0AH 05H 00H 00H FFH 00H 8DH 41H
2.3 Preset multiple registers (function code 16)

Function code 16 (decimal) (10H in hexadecimal) allows the user to change the
contents of multiple registers and to write to registers that support the write
function.
27
Note that it is forbidden to force writes to units
that do not have writable attributes.
The following example modifies the data at register address 0100H of slave #10 to 1.
The register data occupies 2 bytes.
Addr Fun Data start Data start Data #of Data #of Byte

0AH 10H 01H 00H 00H 01H 02H
Value Value CRC16 CRC16

hi lo lo hi
00H 01H 04H 60H
The normal response to a preset multiple register request is to respond with the
slave address, function number, data start address, number of data, and CRC check
digit after the register value has changed.

Chapter 4 Bluetooth Connectivity Instructions
40
1. Bluetooth resource confirmation
First make sure your computer is equipped with a hardware device for Bluetooth, as not all computers
come with Bluetooth capability. This can be checked in the device manager, for example.
2. Turn on Bluetooth (controller should be powered on)

There are many ways to turn on Bluetooth in Win10, you can select "Devices" from "Settings" as
shown in the picture.
41
Then click into it and select "Bluetooth" on the left side, so that you can turn on Bluetooth through the
Bluetooth switch option, the effect is as follows.
There is another way to turn on Bluetooth directly from the notification bar by clicking the Bluetooth
button:.
42
But other Bluetooth features can still be set only in the settings screen just now, so you can right-click
the Bluetooth button in the notification bar and choose to jump to the settings screen at
3. Add Bluetooth virtual serial port

Follow the steps shown in the figure below.
43
44
Select HC-04, password "1234"
Successful pairing tips
45
Select the "COM Port" tab, the effect after adding the port is as follows, the COM5 corresponding to
HC-04 'Serial Port' is the virtual serial port number, note that it must be the port with " Serial Port".
46
Chapter 5 Instructions for using the monitoring software
47
Before using the software, you need to connect to the computer via serial
(RS232/RS485/Bluetooth/Optical) and make sure the parameters of the controller and the computer are
the same, and the protocol is MODBUS.

 Open the software VL230, no data by default, and select the file for port configuration.
 Open and scan the serial port, select the Bluetooth virtual out serial port, do not modify other
parameters, tap open channel and finally return.
48
 Returns to the Real Time Data screen, on which the controller's data is displayed during normal times.
 When you need to set the parameters, you can tap "Parameter Management" and then set the
parameters in the pop-up screen.
49
 You can also click on other function tabs, such as "Historical Data", "Alarm Log", "Event Log", and
Harmonic Data. The corresponding interface of the software is as follows.
 When the communication is not working properly or the data is incorrect, you can tap Communication
and the software will pop up a live message of the communication.
