Description
The Display Data Polling and Processing Module (Mod X4M) is designed for Hall Flow Sensors, providing seamless data communication and control using the Modbus RS485 protocol. This module supports up to four inputs, ensuring accurate and efficient data handling for industrial applications. Its versatile communication features make it an essential tool for integrating flow sensor data into larger monitoring systems.
Product Features:
- Modbus Protocol Compliance: Fully compliant with Modbus protocol instructions, supporting command codes 0x03, 0x06, and 0x10 for robust data communication.
- Versatile Voltage Range: Operates within a wide DC voltage range of 5-24V, suitable for various industrial settings.
- Configurable Parameters: Includes adjustable baud rate, device address, and flow meter constant K value for customized setup.
- Real-Time and Cumulative Data: Displays both real-time flow rates and cumulative flow data for comprehensive monitoring.
- Register Functions: Includes addresses for baud rate, device address, flow constants, and accumulated flow data.
- Precautions: Device requires a restart for parameter changes to take effect. Ensure pipelines are closed before clearing accumulated flow.

Instructions for use
This product complies with MODBUS protocol instructions
Available command codes 0x03, 0x06, 0x10

This protocol follows the MODBUS protocol instructions
Register address Register function
0x0000 baud rate
0x0001 device address, can be modified to 0x0001-0x00FE (decimal 1-254)
0x0002 Sensor pulse K value, the value read and written is 10 times the actual value
0x0003 Permanent accumulated flow high register, unit, L
0x0004 Permanent cumulative flow low register, unit, L
0x0005 Permanent cumulative flow decimal, the reading is 100 times the actual value, unit, L

0x0007 Temporary accumulated flow high register, unit, L
0x0008 Temporary accumulated flow low register, unit, L
0x0009 Temporary cumulative flow decimal, the reading is 100 times the actual value, unit, L
0x000A Temporary cumulative flow pulse value
0x000B Real-time flow, unit: L/min, the reading is 100 times the actual value
0x000C output point 1, control solenoid valve 1, input 0x00FF, turn on, 0x0000, turn off
0x000D output point 2, control solenoid valve 2, input 0x00FF, turn on, 0x0000, turn off
The baud rate defaults to 9600 and the reading is 0. If you modify the baud rate, please modify the parameters as follows. (The parameters that can be modified are 0-3. If the data input is not a value between 0-1, the baud rate is 9600, but it will be displayed as the modified value is not 0 when reading)
Register parameters Baud rate
0 9600
1 4800
Baud rate parameter modification method:
1. The default baud rate is 9600, and the reading is 0.
2. If you modify the baud rate, modify the parameters as follows. (If you enter a value that is not in the table, the baud rate will be restored to 9600, but it will be displayed as the modified value is not 0 when it is read.)
Precautions:
1. After the address, baud rate, K value, and permanent cumulative flow are modified, the device needs to be restarted to take effect.
2. Please close the pipeline before clearing the accumulated flow to prevent water from passing through after the clearing. After 60 seconds, the value will change. If the program changes the value again, the accumulated flow cannot be reset to zero.
3. The temporary accumulated flow will be cleared after power failure, and the permanent accumulated flow will be recorded once every 60S. (The change in flow rate must exceed 1L within 60S to be recorded)
