Module Setting

This document introduces how to setup parameter and data tag point information in configuration for northbound applications and southbound drivers.

TIP

uint16 corresponds to the word type. uint32 corresponds to dword type.

Modbus

The modbus protocol includes three drivers: modbus RTU, modbus tcp, and modbus RTU over TCP.Except for the device configuration, the three protocols support the same data types and address formats.

Modbus TCP / Modbus RTU over TCP Parameter Setting

Parameter	Description
connection mode	The way the driver connects to the device, the default is client, which means that the neuron driver is used as the client
host	When neuron is used as a client, host means the ip of the remote device. When used as a server, it means the ip used by neuron locally, and 0.0.0.0 can be filled in by default
port	When neuron is used as client, port means the tcp port of the remote device. When used as a server, it means the tcp port used by neuron locally. default 502
timeout	Timeout for sending requests to the device

Modbus RTU Parameter Setting

Parameter	Description
device	Use a serial device, e.g."/dev/ttyUSB0"
stop	stopbits, default 1

Support Data Type

• INT16
• INT32
• UINT16
• UINT32
• FLOAT
• BIT
• STRING

Address Format

SLAVE!ADDRESS[.BIT][#ENDIAN][.LEN[H][L][D][E]]

SLAVE

Required, Slave is the slave address or site number.

ADDRESS

Required, Address is the register address.The Modbus protocol has four areas, each area has a maximum of 65536 registers, and the address range of each area is shown in the table below. It should be noted that the storage area as large as 65536 is generally not required in practical applications. Generally, PLC manufacturers generally use an address range within 10000. Please pay attention to fill in the correct point address according to the area and function code of the device.

AREA	ADDRESS RANGE	ATTRIBUTE	REGISTER SIZE	FUNCTION	DATA TYPE
coil	000001 ~ 065536	read/write	1bit	0x1,0x5,0x0f	bit
input	100001 ~ 165536	read	1bit	0x2	bit
input register	300001 ~ 365536	read	16bit	0x4	bit,int16,uint16,int32,uint32,float,string
hold register	400001 ~ 465536	read/write	16bit	0x3,0x6,0x10	bit,int16,uint16,int32,uint32,float,string

TIP

Some device documents use function codes and register addresses to describe instructions. Because register address numbers start from 0, the register address range for each region is 0 to 65535. First, determine the highest digit of the address according to the function code, and add 1 to the register address as the address of Neuron.

example, function is 0x03, and register address is 0, then address used by neuron is 400001. function is 0x02, and register address is 5, then address used by neuron is 100006.

.BIT

OPC UA

Parameter Setting

Parameter	Description
endpoint url	The address of the remote access plc, the default value is opc.tcp://127.0.0.1:4840/
username	The user used when connecting to plc
password	The password used when connecting to plc
cert	The certificate to provide login user authentication
key	The private key to provide signature and encrypted transmissions

Authentication mode:

• anonymos, requires OPCUA server to enable anonymous login;
• username-password, The OPCUA server needs to create a username with access permission. Neuron will automatically match the security Settings of OPCUA server and try to log in.
• cert-key + anonymos, which requires OPCUA server to enable appropriate security settings and set certificates, and enable anonymous login;
• cert-key + username-password, the OPCUA server must have created a username with access permission, and enable appropriate security Settings and set the certificate;

Certificate Setting

OPCUA can login to OPC-UA server by user self-signed certificate, certificate and key must meet the following conditions.

• CERTIFICATE and KEYFILE must be set at the same time
• Certificate must be generated by X.509v3 standard
• The SAN field of the Certficate must contain URI:urn:xxx.xxx.xxx, with the "xxx" part being a custom part
• Certificate file and key file must be encoded with DER format

The certificate file can be imported into the target server in advance and set as trust, or it can be set by neuron and submitted automatically and then set as trust by the server.

Certificate generation steps(Windows/Linux/Mac):

$openssl req -config localhost.cnf -new -nodes -x509 -sha256 -newkey rsa:2048 -keyout localhost.key -days 365 -subj "/C=DE/O=neuron/CN=NeuronClient@localhost" -out localhost.crt
$openssl x509 -in localhost.crt -outform der -out client_cert.der
$openssl rsa -inform PEM -in localhost.key -outform DER -out client_key.der
$rm localhost.crt
$rm localhost.key

The *.cnf file specified by -config can be modified using the template file for openssl to be modified to include the following configuration section:

[ v3_req ]

# Extensions to add to a certificate request

basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names

[ alt_names ]
URI.1 = urn:xxx.xxx.xxx
DNS.1 = localhost
#DNS.2 = localhost
IP.1 = 127.0.0.1
#IP.2 = 0.0.0.0

-days can set the value as desired.

Certificate conversion

You can convert PEM certificate and private key to DER format by following steps and commands

1. Save all the contents including "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" as 1.crt;
2. Save all the contents including "-----BEGIN PRIVATE KEY-----" and "-----END PRIVATE KEY-----" as 1.key;
3. Execute the following command:

openssl x509 -in 1.crt -outform der -out cert.der   
openssl rsa -inform PEM -in 1.key -outform DER -out key.der

DL/T645-2007

The dlt645 protocol supports serial and tcp connection.

Parameter Setting

serial

Parameter	Description
device	Use a serial device, e.g."/dev/ttyUSB0"
stop	stopbits, default 1
parity	parity bit, default 2, which means even parity
baud	baudrate, default 9600
data	bytesize, default 8
timeout	Timeout for sending requests to the device

TCP

Parameter	Description
connection mode	The way the driver connects to the device, the default is client, which means that the neuron driver is used as the client
host	When neuron is used as a client, host means the ip of the remote device. When used as a server, it means the ip used by neuron locally, and 0.0.0.0 can be filled in by default
port	When neuron is used as client, port means the tcp port of the remote device. When used as a server, it means the tcp port used by neuron locally. default 502
timeout	Timeout for sending requests to the device

Support Data Type

• DOUBLE

02 zz zz ff	read
04 00 3~9 ff	read

Sparkplug_B

Data collected by Neuron from the device can be transmitted from the edge to the Sparkplug_B application using the Sparkplug_B protocol. Users can also send data modification instructions to Neuron from the application. Sparkplug_B is an application-type protocol that runs on top of MQTT, so the setup in Neuron is similar to the MQTT driver.

Parameter Setting

Parameter	Description
group-id	The top-level logical group in Sparkplug_B, which can represent an entity such as a factory or workshop, required
client-id	MQTT client ID, A unique identifier that can represent the edge end, required
ssl	Whether to enable mqtt ssl, default false
host	MQTT Broker host, required
port	MQTT Broker port number, required
username	Username to use when connecting to the broker, optional
password	The password to use when connecting to the broker, optional
ca	ca file, only enabled when the ssl value is true, in which case it is required
cert	cert file, only enabled when the ssl value is true, optional
key	key file, only enabled when the ssl value is true, optional
keypass	key file password, only enabled when the ssl value is true, optional

NON A11

The non a11 plugin is used for NON-A11 device.

Parameter Setting

Parameter	Description
connection mode	The way the driver connects to the device, the default is client, which means that the neuron driver is used as the client
host	When neuron is used as a client, host means the ip of the remote device. When used as a server, it means the ip used by neuron locally, and 0.0.0.0 can be filled in by default
port	When neuron is used as client, port means the tcp port of the remote device. When used as a server, it means the tcp port used by neuron locally.
site	NON-A11 device site number.
