Operating Modes - Siemens CP-8000 User Manual

System Components and Technical Data
·
Data transmission in relay operation mode (multi-point traffic with routing)
─ Main and Standby Transmission Line
·
Functions for supporting redundant communication routes
─ NUC redundancy (Norwegian Users Convention)
− NUC redundancy controlling station
─ 1703 redundancy
− Listening mode with passive
− Tristate of the RS-232 interfce with passive
·
Special functions
─ Summer time bit (SU) = 0 for all messages in transmit direction (summer time bit in
time tag)
─ Day of week (DOW) = 0 for all messages in transmit direction (day of week time tag)
─ Originator address = 0 for all messages in transmit direction
