5.5.14.1 Functions
Communication of a substation with a central station (SAT SK 1703 Slave).
• Multi-point traffic slave for the transmision of SAT 1703 standard formats (external data-
base formats)
PCBST0 is substation
• Traffic handling optional according to "SK 1703 Multi-point traffic (Master = PCBM00,
PCBM10, PCBMA0) or "Radio relay operation“ without routing procedure (Master =
SKSZ40, SKSZA0)
• Message formats according to IEC 60870-5-1/FT1.2
• Puls code modulation; byte asynchronous
• Transmission rate 50 up to 19200 bps
• Protection of the messages with hamming distance HA = 4
• Control of the traffic handling with handshaking and message repititions upon acknowl-
edgement failure
• Check of received messages
• Bundle in send/receive direction
• Chaining in send direction
• Linear measured value adaptation
• Timesetting and time synchronization of the automation unit
• Multi-hierarchical configurations possible (to substations in multi-point traffic further auto-
mation units can be connected)
Note
The previously mentioned functions are described in detail in the document SICAM RTUs • Ax 1703
