PCD3.M6880 Standby Controller

1.5.1

Architecture of the PCD3.M6880

The PCD3.M6880 standby controller has two independent processors (CPU0 and

CPU1). Both processors have their own independent PCD media (F, R, T, C, DB/

TX).

The redundant CPU1 runs the redundant user program and controls the shared

inputs/outputs of the PCD3.T668 remote I/Os. The redundant programs in the

primary and secondary PCD3.M6880s are identical. During normal operation,

only the active PCD runs the redundant program. CPU1‘s internal used PCD

media (F, R, T, C, DB/TX) are transferred from the active to the standby PCD via

the Ethernet interface 2 (ETH2.x). In the event of a fault, the standby PCD takes

over operation without interruption, and runs the redundant program using the last

process image from the active PCD.

Depending on requirements, the user programs of the main CPU0 can be different

in the primary and secondary PCD3.M6880. CPU0 has the same capabilities

as a standard PCD (e.g. PCD3.M5560). Local I/Os in the PCD‘s slots, and the

I/O expansion modules, are controlled by CPU0. External systems and devices

(SCADA systems, web browsers and other external devices) communicate only

with CPU0. CPU0‘s internal PCD media (F, R, T, C, DB) are not synchronized

between the active and standby PCD.

CPU1‘s program cannot directly access the local IOs or CPU0‘s media (and vice

versa). Data is exchanged between CPU0 and CPU1 using a data exchange

mechanism. The data to be exchanged (PCD media) are define in global symbol

files. This data is automatically exchanged between CPU0 and CPU1 on each

program cycle.
