XINJE Modbus RTU

The Neuron XINJE Modbus RTU plugin is for collecting XINJE PLC tags using the Modbus RTU protocol, supporting XINJE XC/XD/XL PLC models.

Add Device

Go to Configuration -> South Devices, then click Add Device to add the driver. Configure the following settings in the popup dialog box.

  • Name: The name of this device node.
  • Plugin: Select the XINJE Modbus RTU plugin.

Device Configuration

After clicking Create, you will be redirected to the Device Configuration page, where we will set up the parameters required for Neuron to establish a connection with the device. You can also click the device configuration icon on the southbound device card to enter the Device Configuration interface.

ParameterDescription
PLC ModelSelects the XINJE PLC model.
Physical LinkSelects the communication medium, either serial or Ethernet.
Connection TimeoutThe time the system waits for a device to respond to a command.
Maximum Retry TimesThe maximum number of retries after a failed attempt to send a read command.
Retry IntervalResend reading instruction interval(ms) after a failed attempt to send a read command.
Send IntervalThe waiting time between sending each read/write command. Some serial devices may discard certain commands if they receive consecutive commands in a short period of time.
EndiannessByte order of tags with 32 bits, ABCD corresponds to 1234.
Serial DeviceOnly needed in Serial mode, the path to the serial device when using a serial connection, e.g., /dev/ttyS0 in Linux systems.
Stop BitsOnly for the Serial mode, the serial connection parameter.
ParityOnly for the Serial mode, the serial connection parameter.
Baud RateOnly for the Serial mode, the serial connection parameter.
Data BitsOnly for the Serial mode, the serial connection parameter.
Connection ModeOnly for the Ethernet mode, you can choose Neuron as the TCP client or server.
IP AddressOnly for the Ethernet mode, the IP address of the device when using TCP connection with Neuron as the client, or the IP address of Neuron when using TCP connection with Neuron as the server. The default value is 0.0.0.0.
PortOnly for the Ethernet mode, the port number of the device when using TCP connection with Neuron as the client, or the port number of Neuron when using TCP connection with Neuron as the server.
Maximum Retry TimesThe maximum number of retries after a failed attempt to send a read command.
Retry IntervalResend reading instruction interval(ms) after a failed attempt to send a read command.

The XINJE Modbus RTU plugin configuration is similar to that of the Modbus RTU driver module.

Configure Data Groups and Tags

After the plugin is added and configured, the next step is to establish communication between your device and Neuron by adding groups and tags to the Southbound driver.

Once device configuration is completed, navigate to the South Devices page. Click on the device card or device row to access the Group List page. Here, you can create a new group by clicking on Create, then specifying the group name and data collection interval.

Upon successfully creating a group, click on its name to proceed to the Tag List page. This page allows you to add device tags for data collection. You’ll need to provide information such as the tag address, attributes, and data type.

For information on general configuration items, see Connect to Southbound Devices. The subsequent section will concentrate on configurations specific to the driver.

Data types

  • BIT
  • INT8
  • UINT8
  • INT16
  • UINT16
  • INT32
  • UINT32
  • INT64

  • BYTES

Address format

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

The address format is nearly the same to that of the Modbus RTU driver module, the only difference is in the ADDRESS part.

SLAVE

Required, Slave is the slave address or site number.

ADDRESS

XINJE PLC maps memory data unit (input/output relay, timer, counter etc) onto the Modbus address space for access through the Modbus RTU protocol. Depending on the PLC model, such address mapping may vary. The Neuron XINJE Modbus RTU plugin frees users from details of the address mapping, and designates the PLC data unit name as the ADDRESS.

Users could check the address mapping according to the PLC model from XINJE official documents, and the following tables are listed here for convenience.

NOTICE

The X and Y area’ data units are numbered in octal.

As an example, for XC1/XC2/XC3/XC5/XCM/XCC PLC models:

  • X0~X7:16384~16384+7
  • X10~X17:16384+8~16384+15
  • X70~X77:16384+56~16384+63

#ENDIAN

Optional, byte order, applicable to data types int16/uint16/int32/uint32/float, see the table below for details.

TIP

The byte order of a tag has a higher priority than the byte order configuration of a node. That is to say, once the byte order is configured for a tag, it follows the configuration of that tag and ignores the node configuration. The byte order can be illustrated using the notation ABCD, which corresponds directly to the sequence 1234. As an example, the ABCD designation represents the standard or default Endianness 1234. (#LL).

.LEN[H][L]

When the data type is STRING, .LEN is a required field, indicating the number of bytes the string occupies. Each register contains four storage methods: H, L, D, and E, as shown in the table below.

SymbolDescription
HOne register stores two bytes, with the high byte first
LOne register stores two bytes, with the low byte first
DOne register stores one byte, and it is stored in the low byte
EOne register stores one byte, and it is stored in the high byte

.BYTES

Optional, read and write the length of bytes type data, applicable to bytes data type.

TIP

A register of the Modbus driver contains 2 bytes. When reading and writing Modbus register data in the bytes data type, please ensure that the bytes parameter is set to an even number.
