Quick use

【Note】This test needs to be carried out with the default factory parameters.

Device preparation
The following table lists the items required for this test:

 Device connection 

 RS485 connection 

Note: When the 485 bus high-frequency signal is transmitted, the signal wavelength is shorter than the transmission line, and the signal will form a reflected wave at the end of the transmission line, which will interfere with the original signal. Therefore, it is necessary to add a terminal resistor at the end of the transmission line so that the signal does not reflect after reaching the end of the transmission line. The terminal resistance should be the same as the impedance of the communication cable, the typical value is 120 ohms. Its function is to match the bus impedance and improve the anti-interference and reliability of data communication.

 Relay output connection 

 Simple use 

• Wiring: The computer is connected to the RS485 interface of ME31-XXAX0060 through USB to RS485, A is connected to A, and B is connected to B.
• Networking: Insert the network cable into the RJ45 port and connect to the PC.
• Power supply: Use DC-12V switching power supply (DC 8~28V) to power ME31-XXAX0060.

Parameter Configuration
Step 1: Modify the IP address of the computer to be consistent with the device. Here I am modifying it to 192.168.3.100 to ensure that it is on the same network segment as the device and that the IP is different. If you cannot connect to the device after the above steps, please turn off the firewall and try again;

Step 2: Open the network assistant, select the TCP client, enter the remote host IP192.168.3.7 (default parameter), enter the port number 502 (default parameter), and select HEX to send.

 Product Function Introduction

DO output
Relay output mode: output different mode output according to the mode set by the user, and the level output is turned on by default.

 Input count
Support counting DI input, users can configure rising edge acquisition, falling edge acquisition, and level acquisition according to their own needs. You can also change the clearing method according to your needs.

Trigger method:

• Rising edge: When the rising edge is collected (it is not counted when it is turned on, it is counted when it is turned off), it will be counted once.
• Falling edge: When the falling edge is collected (counting when it is turned on, and not counting when it is released), count once.
• Level: Two edges are collected and counted once respectively.

Clearing method:

• Automatic: The device will automatically clear each time the DI count value register (0x09DF~0x09E6) is read. Manual: In manual mode, it is necessary to write 1 to the clear signal register (0x0AA7~0x0AAE), and each holding register controls one clear signal.

Level output
Output according to the level set by the user, the switch characteristic of the level mode is similar to the function of a self-locking switch.

Pulse output
After the switch output DO is turned on, the switch output DO is automatically turned off after maintaining the set pulse width time (in ms). The pulse width setting range is 50~65535ms (50ms by default).

Follow mode
According to the follow source configured by the user (when the device has AI acquisition or DI detection function, both DI or AI can be used as the follow source, otherwise this function is useless) to change the relay state, and multiple outputs can follow the same follow source output. To put it simply, DI detects the input, and automatically outputs a relay that uses it as a follow source (for example: DI is 1, DO is closed). When the follow mode is turned on, the follow source should be configured at the same time, otherwise it will follow the first input by default.

Reverse follow mode
According to the follow source configured by the user (when the device has AI acquisition or DI detection function, both DI or AI can be used as the follow source, otherwise this function is useless) to change the relay state, and multiple outputs can follow the same follow source output. To put it simply, DI detects the input, and automatically outputs the relay that follows it as the source (for example: DI is 1, DO is disconnected). When the follow mode is turned on, the follow source should be configured at the same time, otherwise it will follow the first input by default.

Trigger toggle mode
According to the follow source configured by the user (when the device has AI acquisition or DI detection function, both DI or AI can be used as the follow source, otherwise this function is useless) to change the relay state, and multiple outputs can follow the same follow source output. Simply put, when DI generates a trigger signal (rising edge or falling edge), DO will have a state change. When the trigger flip mode is turned on, the following source should be configured at the same time, otherwise it will follow the first input by default.

Power-on state
According to the state set by the user. After the device is powered on, the output relay is turned on according to the state set by the user, and it is turned off by default.

Modbus Gateway
The device can transparently transmit non-native Modbus commands from the network/serial port to the serial port/network, and the local Modbus commands are directly executed.

 Modbus TCP/RTU protocol conversion
After it is turned on, the Modbus TCP data on the network side will be converted to Modbus RTU data.

Modbus Address Filtering
This function can be used when some host software or configuration screen is used as the host to access the serial port of the device, and the gateway function of the device is used, the slave is at the network end, and the Modbus TCP to RTU function is turned on. Multiple slaves on the bus may cause data confusion. At this time, enabling address filtering can ensure that only the specified address can pass through the device; when the parameter is 0, the data will be transparently transmitted; when the parameter is 1-255, only the set slave machine address data.

Modbus TCP Protocol Data Frame Description

TCP frame format：

Transaction ID	Protocol ID	Length	Device address	Function code	Data segment
2 Bit	2 Bit	N+2 Bit	1 Bit	1 Bit	N Bit

• Transaction ID: It can be understood as the serial number of the message. Generally, 1 is added after each communication to distinguish different communication data messages.
• Protocol identifier: 00 00 means Modbus TCP protocol.
• Length: Indicates the length of the next data in bytes.

Example: get DI status

01 00	00 00	00 06	01	02	00 00 00 04

Active upload

• The device supports the function of uploading analog input values at regular intervals. Setting the value of the corresponding register can control the interval time and whether to upload.
• Devices with digital input will actively upload once after successfully connecting to the server, and then the digital input will be uploaded following the status change. Devices with analog input will report the status of analog input according to the configured active upload time period (the configuration period is 1-65535 ).
• When it is set to 0, the upload is disabled; if it is set to other positive integer value N, the upload will be performed at intervals of N seconds.

[Note] The device can only be valid if it is configured in client mode, and the register value is non-zero to enable active upload.

The status data 01 returned above indicates that the output DO1 is turned on.

Control coil (DO) state
Support operation of single coil (05), operation of multiple coils (0F) function code operation.
Use the 05 command to write a single command, for example:

01	05	00 00	FF 00	8C 3A
Modbus address	Function code	Register first address	Continuity: FF 00Close: 00 00	CRC check code

After sending the above command to the device through the 485 bus, the device will return the following values:

01	05	00 00	FF 00	8C 3A
Modbus address	Function code	Register firstaddress	Operation method	CRC check code

The DO1 coil is turned on.
Use 0F function code as the command to write multiple coils, for example:

01	0F	00 00	00 04	01	0F	7E 92
Modbus address	Function code	Initial address	Number of coils	Bytes of data	Control coil data	CRC check code

After sending the above command to the device through the 485 bus, the device will return the following values:

01	0F	00 00	OO O4	54 08
Modbus address	Function code	Register address	Number of coils	CRC check code

The coils are all on.

01	03	05 78	00 01	04 DF
Modbus address	Function code	Register firstaddress	Number of registers read	CRC check code

After sending the above command to the device through the 485 bus, the device will return the following values:

01	03	02	00 00	B8 44
Modbus address	Function code	Bytes of data	Returned data	CRC check code

The above 00 00 means that DO1 is in level output mode.

 Operation holding register
Support operation of single register (06), operation of multiple registers (10) function code operation. Use 06 function code to write a single holding register, for example: set the working mode of DO1 to pulse mode:

01	06	05 78	00 01	C8 DF
Modbus address	Function code	Register address	Write value	CRC check code

After sending the above command to the device through the 485 bus, the device will return the following values:

01	06	05 78	00 01	C8 DF
Modbus address	Function code	Register address	Write value	CRC check code

If the modification is successful, the data in the 0x0578 register is 0x0001, and the pulse output mode is turned on.
Use function code 10 to write multiple holding register commands, for example: set the working mode of DO1 and DO2 at the same time.
