The Indactic 2033 protocol was developed in the late 80ies by the BBC
company (ABB). It found high resonance in the energy sector for the automation of
transformer stations enabling communication between a control station and
several RTUs. Like its preceding version
Indactic 33/41, this protocol belongs to the "Indactic 33" protocol
The Indactic 2033 protocol is an improvement of Indactic 33/41and is to a great extent downward compatible.
Both pseudo half duplex and half duplex modes may be employed for data
transmission, but the first is more widely used. An "extended addressing mode"
which allows connecting up to 4095 RTUs to a single line was also introduced. In the "base addressing mode" up
to 15 RTUs can be connected
Its function range was extended by 12-bit measured values and 24-bit counter
Otherwise its function range is very much similar to that of the
Indactic 33/41 protocol.
