The Indactic 23 protocol was developed by ABB and is used to link up RTUs and
control stations in the energy índustry. Siemens, too, has developed compatible
controller boards to enable connection of their own systems with ABB systems.
The telegram frame of the protocol complies with DIN 19244, format class
FT1.2 which also applies to the IEC870-5-101 protocol. In multi-point operation up
to 254 substations can be connected. Indactic 23 always uses half duplex communication.
