Chinese plant gets Trusted for safety
Engineers at Qilu, one of the largest polyethylene production sites in China, have upgraded their plant's safety system by installing an ICS Triplex 'Trusted' system
The remote I/O uses triplicated links to offer the same fault-tolerant operation as locally mounted Trusted(tm) units.
Unlike merely fail safe operation, fault-tolerant operation uses TMR architecture to identify and outvote processor mismatches to keep running safely in the presence of a fault, almost entirely eliminating spurious plant trips.
Trusted(tm) is certified by TÜV to DIN V VDE 0801 RC(AK)6 for Fire and Gas, Emergency Shut Down and similar highly critical applications where system failures cannot be contemplated.
