XP‐8xx7‐CE6 And iDCS‐8000 (Or ET‐7000 Or Modbus TCP Slave device) Redundant System
The redundant system of two XP‐8xx7‐CE6 plus one or two iDCS‐8000 I/O (Figure 1).
(Refer to the figure 2 for connecting more redundant stations.)
(Refer to the figure 3 for connecting more iDCS‐8000 and the figure 4 for connecting ET‐7000 or others).
●Features :
■Redundant PAC and redundant ethernet ports : Two PACs, each has two Etrhernet ports.
■The PC/HMI/SCADA can just connect one IP address (the“Active_IP1”) to access to the XP‐8xx7‐CE6 redundant system. When the active PAC is damaged for some reasons, the control right will auto‐switch to the other PAC and this“Active_IP1”will also auto‐switch to belong to the new active PAC.
■The PAC switching time is about 0.5 second.
■The iDCS‐8000 can have two redundant CPU cards (each with one ethernet port) and two redundant power cards . All I/O cards can also be redundant (two cards for one group I/O). If one is damaged, the other one will take over the work. (or I/O cards can be just a single card for one group I/O) 5. The power cards, CPU cards and I/O cards of the iDCS‐8000 can be hot‐swapped.
