Redundancy Support
- Simplex configuration
- Dual configuration (uses S/SL2 and R/SL1 ports)
- TMR configuration (uses all three ports R/S/T)
- No single point of failure during maintenance shutdowns.
IONet Communication
- Private Ethernet for Mark VIe I/O packs only.
- Uses IEEE 1588 for clock sync within 100 microseconds.
- This controller does NOT host application I/O on backplane.
- External data moves to/from control database via IONet.
Software and HMI
- HMI: ControlST V07.00.00C or later
