Communication between the SPECTRUM control system and
ipConv protocol converter uses IEC 60870-5-101 in balanced mode, with the
protocol converter as the slave.
Downlink communication is realized via a telecontrol transformer TCT using
the Indactic 21 protocol, with the protocol converter as the master.
For this application, messages and measured values are only transmitted towards
the control system (control function).
