Chapter 4 Communication Setting Low byte setting For example: Write the lower limit of digital I/O output to the laser displacement meter of device address 0x01 which need to set high byte of upper limit(A8C1H) and low byte of lower limit(A925H).
The RTU command is as follows Lower limit = 40000 um (high byte is 0x0000, low byte is 0x9C40) Command message Reply message High byte setting Low byte setting Laser Displacement Operating Manual 4-8 Address 0x01 Function code 0x06 Initial address (high) 0xA8 Initial address (low) 0x5D Data content (high) 0x88 Data content (low) 0xB8 CRC checksum (low) 0x5E CRC checksum (high) 0x0A Address 0x01 Function code 0x06 Initial address (high) 0xA8 Initial address (low) 0x5D Data content (high) 0x88 Data content (low) 0xB8 CRC checksum (low) 0x5E CRC checksum (high) 0x0A Address 0x01 Function code 0x06 Initial address (high) 0xA8 Initial address (low) 0xC1 Data content (high) 0x00 Data content (low) 0x00 CRC checksum (low) 0xF8 CRC checksum (high) 0x56 Address 0x01 Function code 0x06 Initial address (high) 0xA8 Initial address (low) 0xC1 Data content (high) 0x00 Data content (low) 0x00 CRC checksum (low) 0xF8 CRC checksum (high) 0x56 Address 0x01 Function code 0x06 Initial address (high) 0xA9 Initial address (low) 0x25 Data content (high) 0x9C Data content (low) 0x40 CRC checksum (low) 0xD1 CRC checksum (high) 0x6D Address 0x01 Function code 0x06 Initial address (high) 0xA9 Initial address (low) 0x25 Data content (high) 0x9C Data content (low) 0x40 CRC checksum (low) 0xD1 CRC checksum (high) 0x6D
