By implementation of up to two (2) NTP LAN Boards 7273(RC) or NTP LAN Boards 7274(RC) (10/100/1000 Mbit/s autosensing, VLAN, Bonding, PRP) system 6844(RC)-SUB becomes a highly accurate NTP Stratum 1 Time Server for synchronization of computers and industrial networks.
System 6844(RC)-SUB can either be delivered with one or two implemented NTP LAN Boards 7273(RC) / one or two NTP LAN Boards 7274(RC) from the factory or subsequently extended by board(s) 7273(RC) / 7274(RC) in the field. The modular design structure of system 6844(RC)-SUB also allows the combination of one board 7273(RC) / one board 7274(RC) with any other function board suitable for system 6844(RC)-SUB.
Features of Base System 6844
- Semi-modular system equipped with max. 2 function boards for system bus
- Channels for parameterization//monitoring:
- Keypad and operating menu via display
- WEB-GUI and SNMP for function boards with LAN interface
- Subsequent extension by additional function boards (depending on configuration of system 6844(RC)-SUB at time of delivery)
- SyncOFF Timer (bridging of reception failure) providing an error-free operation even under difficult reception conditions
- Redundant multiple test mechanism of the synchronisation signal providing a correct and leap-free signal evaluation
- High free running accuracy
- Maintenance-free back-up clock for three days
- System completely maintenance-free
- Options:
- Activation of Remote Function of board 6844(RC)-SUB
- Power supplies for various operating voltages
- Redundant power supplies
- Specific hardware and software customizations
Additional Features for System 6844RC-SUB (System 6844RC-SUB with activated Remote Function of Board 6844(RC)-SUB)
- Channels for parameterization / monitoring:
- Keypad and operating menu via display
- WEB-GUI and SNMP for function boards with LAN interface
- Serial connection via the hmc (hopf Management Console)
