† W900/I-9 only | * I-9 only (hidden for I-6) | ** I-6/W600 only (hidden for I-9) | ‡ last lag only | § lead-lag only | Relay type shown in [brackets] in channel header | Pulse-only modes hidden for powered/dry-contact relays
Function codes: FC3 (read/write holding registers) and FC4 (read-only input registers) are interchangeable for read operations. FC1/FC2 may also be used to read boolean fields as coils — coil addresses are not shown here. For full function code details see Walchem Intuition Modbus Manual section 4.1.3.
