2. F1 parameter group-analog configuration parameters
| Parameter | parameter name | Scope and description | Defaults | Read write |
| F1-0 | Input type selection | 0:0~10V or 0~20mA corresponds to 0~100.0% | 0 | Read write |
| F1-1 | Input filter time | 1: 2~10V or 4-20mA corresponds to 0~100.0%, and it is 0 when it is lower than 2V or 4mA. | 0.200 | Read write |
| F1-2 | Input gain | Analog input filter time, range: 0-10.000S. The greater the filtering time, the stronger the filtering.

The formula of analog input gain and bias is: adjustment result = (acquisition value + offset) × gain
F2 parameter group relay output dosing (with relay Output version)
| Parameter | parameter name | Scope and description | Defaults | Read write |
| F2-O | Relay output status configuration | When the output conditions are met, the relay output status:
0: No control (always open) 1: Relay closed 2: Relay open (not satisfied Closed on condition) |
0 | Read write |
| F2-1 | Condition type | 0: greater than comparison value 1, 1: less than comparison value 2.
2: Greater than comparison value 1 and less than comparison value 2. |
0 | Read write |
| F2-2 | Comparison value 1 | Range: 0-100.0% | 50.0 | Read write |
| F2-3 | Comparison value 2 | Range: 0-100.0%. | 50.0 | Read write |
| F2-4 | Hysteresis interval | In order to prevent the relay output from operating frequently near the comparison value, hysteresis interval parameters are introduced
Range: 0.0%~80.0%. |
Read write |
Examples are given to illustrate the action mechanism of the hysteresis interval: for example, if “F2 condition type” is selected as “0: greater than comparison value 1”, “F22 comparison value 1” is set as 50.0%, and “F24 hysteresis interval” uses the default value of 5.0%. When power on, the collected value increases gradually. When it is greater than 50.0% + 5.0% / 2, the output condition is satisfied. If the collected value decreases, it needs to be less than 50.0% – 5.0% / 2 to reach the non output condition.

Four、Communication protocol and communication method of “with R485 communication version”
1. The user host accesses the collected value of the display table
Communication uses standard Modbus-RTU protocol, read with multiple read command 03H. The returned parameter value is the integer displayed by the nixie tube with the decimal point removed. For example, the F0-0 nixie tube display value is 60.0, and the value read by communication is 600. The Modbus register address has a corresponding relationship with the parameter, such as
The Modbus register address corresponding to F72 is 0702H, that is, 7 in F7-2 is the high 8-bit value, and 2 in F72 is the low 8-bit value.
For example, read the parameters F0-0 and F0-1 parameter values (the F1 parameter group uses the default parameter settings), the format is as follows:
| host sends a selective dance | Slave (HXDSB0XAI) response data | |||
| Slave address is F70 | 01H | Slave address ( F7-0) | 01H | |
| Mbus function number | 03H | Modbus function number | 03H | |
| Start address (high byte) | 00H | Returns the number of bytes (4 bytes) | 04H | |
| Start address (low byte) | 00H | High byte of address content | 02H | |
| Read word count (high byte) | 00H | low byte of the content of 000 address | 58H | |
| Read word count (low byte) | 02G | High byte of 0001H address content | 02H | |
| CRC (low byte) | C4H | Low byte of 0001H address content | 58H | |
| CRC (high byte) | OBH | CRC (low byte) | 7AH | |
| CRC (high byte) | C2H |
In the above example, the read f0-0 and f0-1 are both 0258h = 600, that is, the collected value f0-0 is 60.0%; the displayed value f0-0 is 60.0
2. Network Description:
Through the inter table networking, the display value of the data collected from the master table can be transmitted to the slave table through RS485. There can be only one master table in a network, and there can be multiple slave tables. In use, only the main table needs to set the corresponding display range, and the slave table does not need to set the display range.
