5. Modbus RTU communication and value calculation
A. Register types:
Register types | Read command |
Write command (Control command) |
Power off | Function |
coil register | 0x01 |
Input --not support Output-support |
Not keep | Can read input value |
Hold register | 0x03 |
1) Coil register:
Input: it is not convenient to read 8 I/O at one time. In order to control each I/O correspondingly, we defined coil register. The register address is 0x0000-0x0007.
Output: it is not convenient to control 8 I/O at one time. In order to control each I/O correspondingly, we defined coil register whose address is 0x0020-0x0028.
Note: The coil is not extra resource, just a method for register addressing---addressing by bit.
2) Holding register:
a. value of input channels: 0x0000
Note: addressing by bit means we only use the first 8 bits; bit0 to bit7 corresponds with I / O1 to I / O8;
b: feedback and value of output channels: 0x0040
Note: addressing by bit means bit 0 corresponds with 1/O1, bit 7 corresponds with 1/O8, bit 8-bit 15 corresponding value we write 0.
3) Reading method:
Coil register: read the responding register directly. 1 means OFF, 0 means ON.
Holding register: Can read all 8 inputs one time. We only use bit0-bit7 of this 16-bit register; each bit represents the state of an input.
4) Control methods:
a. Use the coil--- write the corresponding coil register directly you can control its corresponding output.
b. Use the holding register--- 8 outputs share 1 holding register, so you can manage each bit separately to control the corresponding output.
