6.2 Function Code
TEMI2500 MODBUS protocol provides two function code subsets for READ/WRITE of D-Register and Loop-Back
detecting test.
Function Code Description
03 Read data in consecutive D-Register in sequence
06 Write data to arbitrary single D-Register
08 Diagnostics(Loop-Back Test)
16 Write data to consecutive D-Register in sequence
When using MODBUS, D-Register has to be subtracted ‘1’ from the D-Register table we offer this
manual, because it starts ‘0’D-Register address on MODBUS protocol.
