MODBUS debugging tool (modscan32) software functions
1.Can automatically display the received data
2. Can debug all devices with modbus protocol
3. You can set the data and time interval to be sent regularly.
4. The host computer can be simulated to use the Modbus protocol host. The Modbus debugging wizard is written in vc and does not require any other files when running.
5.Support HEX or ASCII code display. It is an essential tool for engineering and technical personnel to monitor and debug serial port programs.
6. Various communication rates, parity checks, and communication ports can be set online without restarting the program. Sending data can be sent in hexadecimal (HEX) format and ASCII code.
MODBUS debugging tool (modscan32) software features
1. Modbus can support a variety of electrical interfaces, such as RS-232, RS-485, etc., and can also be transmitted on various media, such as twisted pair, optical fiber, wireless, etc.
2. The frame format of Modbus is simple, compact, and easy to understand. It is easy for users to use and easy for manufacturers to develop.
3. Standard and open. Users can use the Modbus protocol for free and with confidence. There is no need to pay license fees and no intellectual property rights will be infringed. Currently, there are more than 400 manufacturers supporting Modbus and more than 600 products supporting Modbus.

FAQ
1. Connection problem
Unable to connect to slave device
reason:
Communication parameters such as baud rate, data bits, stop bits, and parity bits are incorrectly set.
The slave device address (Device ID) is set incorrectly.
The external connecting wire is loose or damaged.
Solution:
Check and confirm that the communication parameter settings in ModScan32 are consistent with the slave device.
Confirm that the slave device address is set correctly.
Check whether the external cable is firmly connected and not damaged.
MODBUS MESSAGE TIME-OUT (timeout error)
reason:
Network delays or instability.
The slave device did not respond or the response timed out.
The communication protocol between ModScan32 and the slave device is incompatible.
Solution:
Check whether the network connection is stable.
Try restarting the slave device.
Confirm that the communication protocol (RTU or ASCII) between ModScan32 and the slave device is set correctly.
2. Data reading and writing issues
Data reading is inaccurate
reason:
The register address or data type setting is wrong.
Internal failure of the slave device or data anomaly.
Solution:
Check and confirm that the register address and data type in ModScan32 are set correctly.
Try using other Modbus debugging tools to verify.
Check whether the slave device is running normally and whether the data is accurate.
Unable to write data
reason:
The slave device does not support write operations.
Wrong write permission setting.
The format or range of the data written does not meet the slave device requirements.
Solution:
Confirm that the slave device supports write operations.
Check and modify write permission settings.
Make sure the format and range of the written data meet the slave device requirements.
