Modbus Communication
‑20‑
Multi‑write is the same as multi‑read and up to 12 parameters can be continuously
written.
If the slave detects a communication frame error or read/write failure due to other
causes, the slave returns a frame of error.
Note
No response is returned for CRC check error.
A read error returned from the slave is 0x83. A write error returned from the slave is
0x86. A multi‑write error returned from the slave is 0x90.
