Ethernet IP
Example:
Writing the following bytes:
0x 01 10 16 2D 00 08 10 00 C0 00 00 00 A8 00 00 00 01 00 00 00 0A 00 00 1F B1
Will result in the IP 192.168.1.10
In detail:
0x 01 Slave address (int32 “01”)
0x 10 Function Code
0x 16 2D Starting Address (5677 in int32 representation)
0x 00 08 Quantity of Registers
0x 00 C0 00 00 Octet 1 (int32 192)
0x 00 A8 00 00 Octet 2 (int32 168)
0x 00 01 00 00 Octet 3 (int32 1)
0x 00 0A 00 00 Octet 4 (int32 10)
0x 1F B1 CRC16
SpectraSensors recommends deactivating the current
measurement before changing any settings. The device will hold
its last analog output value until the next measurement.
