String example 1: Change a Static IP Address
Change the IP address of a meter from 192.168.2.8 to 192.168.2.9.
Note: Update the entire IP address, not just the “8” to “9.”
Internally, the meter uses a single string buffer for all string register operations
and unspecied entries continue to contain the previous buffer contents unless
specically written. Write every register from the beginning of the block to the end.
Specic Implementation Examples – Element A Set to ID 1
Note that in Modbus, the CRC communicated is LSB then MSB.
VIA MODBUS RTU (SERIAL), USING FUNCTION
CODE 6/WRITE SINGLE REGISTER.
VIA MODBUS RTU (SERIAL), USING FUNCTION
