RS232 serial port MODBUS protocol industrial reader/writer reader configuration software is dedicated to configure the parameters of the industrial automation reader/writer equipment (high-frequency card reader and low-frequency card reader) of the morning control automation Mudbus communication protocol. Users can use it This program performs related configuration operations on the card reader.
Figure 1.1 MODBUS card reader configuration software
The card reader has a default parameter configuration when it leaves the factory. In actual use, the configuration requirements are different for different usage scenarios. When the user needs to change the configuration of the card reader, there are two methods that can be used, one is Send relevant commands to the card reader to configure the card reader; the second is to operate directly by using this program.
When using the card reader, the user configures the card reader to meet the corresponding requirements, and can use the relevant command protocol to operate the card reader, but the operation process is relatively cumbersome, and the user can use this program to read the card The configuration of the program is directly carried out. Compared with the command data operation, the graphical interface operation of the program is relatively convenient to use.
1. MODBUS card reader configuration software function
The MODBUS card reader configuration software of this program is mainly used for the configuration operations of the card reader. The specific functions are as follows:
1. Search device communication information
This program can automatically obtain the communication information of the program, no need to manually select the relevant configuration
2. Configure the communication mode of the card reader
It includes modifying the station number, baud rate, parity and check method of the card reader, and the station number of the card reader cannot be set to 0
3. Configure the card reader mode
The modes include standard Modbus, Enchance Mode, Continue Read Mode and Read Once Mode. Please refer to Chapter 3.3 for the specific description of each mode. The available modes of each type of card reader are inconsistent, please refer to the manual of each type of card reader for the specific mode of use.
4. Data operation of the card reader register
It can perform related read and write operations on the registers of the card reader, support instructions 03, 06, 16 for user convenience
2. MODBUS card reader configuration software interface introduction
The MODBUS card reader configuration software is mainly used for reader-related configuration operations, which is convenient for users to configure the required card reader information. The main interface of the program is introduced as follows:
Figure 2.1 Main interface of MODBUS card reader configuration software
The main interface of the MODBUS card reader configuration software is mainly divided into four areas, namely the device model area, the communication mode configuration area, the station number and the card reading mode area, and the register data operation area.
- The device model area shows the type of card reader, which is currently a high-frequency card reader.
- The communication mode configuration area is mainly divided into the search device and the configuration communication mode. After the user selects the card reader to connect to the serial port of the host computer, click the search device button to automatically search for the device. After the search is completed, the user can perform the communication mode For configuration, please refer to chapter 3.2 for specific operation steps.
- The station number and card reader mode are used to configure the card reader station number and card reader mode. The card reader modes include standard Modbus, Enchance Mode, Continue Read Mode and Read Once Mode.
- The register data operation area is convenient for users to operate the card reader registers.
