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

F2-3 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

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„ÄĀCommunication 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.
