4. Product Features
4.1 Working Mode
The working mode is divided into master mode and slave mode, which are configured through Modbus register 40081
(0x0050). When the register value is 0, it is the master mode; when the register value is 1, it is the slave mode, and the
default slave mode.
4.1.1 Slave Mode
In slave mode (register value is 0x01), the data sent by the network or 485 bus (sender) to the device complies with the
Modbus RTU and Modbus TCP protocols, and the address in the data is the device address, and the device will respond
with the same protocol. If the data sent by the network end or the 485 bus end to the device does not meet the Modbus
RTU and Modbus TCP protocols, or if it meets the Modbus RTU and Modbus TCP protocols but the data address is not
the device address, the data at the sending end will be discarded.
In the slave mode, the device can directly connect to the device in the master mode through the 485 bus, so that when the
slave is not connected to the Internet, the network can also access the data of the slave through the host.
4.1.2 Host Mode
In the host mode (the register value is 0x00), the data sent by the network terminal or the 485 bus terminal (sender) to the
device complies with the Modbus RTU and Modbus TCP protocols, and the address in the data is the device address, and
the device will respond to the sender with the same protocol. ;If the data sent by the network terminal or the 485 bus
terminal to the device does not meet the Modbus RTU, Modbus TCP protocol, or meet the Modbus RTU, Modbus TCP
protocol but the data address is not the device address, the data from the 485 bus will be transmitted to the network , the
data from the network will be transmitted to the 485 bus.

This function of the host mode can realize the device cascading function and the data transmission between the 485 bus
and the network.
4.2 Basic functions of IO
4.2.1 Digital DO output
Read digital DO output
Function code: 01, read coil status
Address range: 00017(0x0010)~00022(0x0015)
Description: The equipment relay is passively output. When the coil is not energized, the relay NC port and COM port
are normally closed, and the NO port and COM port are normally open, and the value is 0; when the coil is energized, the
phenomenon is opposite, the relay NC port and COM port are disconnected Open, NO port and COM port are closed, the
value is 1. Query the relay status by command.
example:
Read the 6-channel switching output status, assuming the return value is 03, corresponding to the binary bit 0000 0011,
the lower six bits represent the switching output status, which are DO6, DO5, DO4, DO3, DO2, DO1 in sequence.

Description: The device relay is passively output, the coil is not energized, the relay NC port and COM port are closed,
and the NO port and COM port are disconnected; the coil is energized, the relay NC port and COM port are disconnected,
and the NO port and COM port are closed. Control relay state by command.

4.2.2 Reading digital DI input
Function code: 02, read (switch value) input status
Address range: 10017(0x0010)~10022(0x0015)
Description: The device defaults to dry contact input. When DI and COM are short-circuited, the read value should be 1;
when DI and COM are not short-circuited, the read value should be 0.
example:
Read the 6-channel switching value input value, DI input terminal DI1, COM1 short circuit, DI2, COM2 not short circuit,
DI3, COM3 short circuit, DI4, COM4 not short circuit, DI5, COM5 not short circuit, DI6, COM6 not short circuit catch.
The read digital input value is 0x05, corresponding to binary 0000 0101, and the six lower six bits represent the digital
input value, which are DI6, DI5, DI4, DI3, DI2, DI1 in sequence.

4.3 IO Features
4.3.1 Pulse count and count clear
The pulse count will not be saved after power off, and the pulse level maintenance time must be greater than 10ms to be
effective. The digital input changes from the open state to the closed state and maintains the closing time of more than
10ms, and then changes to the open state to complete one pulse count.
Read pulse count value
Function code: 03, read holding register
Address range: 40049 (0x0030)~40054 (0x00335)
Description: The maximum value of pulse count is 65535
example:
DI1 has detected 16 pulses currently, DI2 has detected 3 pulses currently, read the digital input count value of DI1 and
DI2

Clear pulse count value
Function code: 06, write holding register
Address range: 40065 (0x0040)
Description: The lower six bits of the register value represent the counts of DI6, DI5, DI4, DI3, DI2, and DI1
respectively. Writing "1" means the count is cleared and the pulse count is restarted. example:
Clear the pulse count value of DI2, DI4, keep the pulse count value of DI1, DI3, D5, D6. The write value should be 0x0a,
the corresponding binary value is 0000 1010, the pulse count value of Modbus RTU protocol clear

4.3.2 Automatic reporting of digital input DI:
The automatic reporting function of digital input is to transmit the change value when the digital value changes. You can
choose to transmit through RS485 or GPRS, or you can turn off the automatic reporting function.
The Modbus register corresponding to the automatic reporting setting of the switch value is 40082 (0x0051), and the
value corresponds to the function:
Turn off the automatic reporting function of the switch value
The switch value is automatically reported and transmitted through RS485
The switch value is automatically reported and transmitted through the GPRS network
The switch value change upload protocol is listed in the following table, in which the frame header 0xAA and 0xBB are
fixed, and the value range of DI1, DI2, DI3, DI4, DI5, DI6 is 0x00, 0x01, 0xFF, among which
0x00 means the digital input is disconnected,
0x01 means the switch input is closed,
