1 ) As switched S1 device

1 ) 스위치로 S1 장치로
2) For personal, environmental or investment protection, you will need fail-safe automation systems (F-systems).

2) 개인, 환경 또는 투자 보호를 위해서는 안전한 자동화 시스템(F-systems)이 필요합니다.

플랜트 구성요소 및 자동화 수준

The schematic diagram below shows the key components of the redundant system from the management level to the control level and the field level
아래의 개략도는 관리 수준에서 제어 수준 및 현장 수준에 이르기까지 중복 시스템의 주요 구성 요소를 보여줍니다

S7-1500R의 예를 사용하여 관리, 제어 및 현장 수준에서 가능한 구성

From the management level, the master PC accesses the various devices at the control and field level. 

The master PC is connected to the CPUs over Industrial Ethernet.
The R-CPUs at the control level are redundant in design.

The IO devices at the field level are connected to the R-CPUs within a PROFINET ring.
The redundant S7-1500R system cyclically exchanges IO data with another PROFINET IO system via a PN/PN coupler.

The left-hand side of the PN/PN coupler is assigned to the S7-1500R redundant system. The right-hand side of the PN/PN coupler is assigned to the CPU 1516-3 PN/DP (IO controller).
The configuration tolerates the failure of one CPU or an interruption in the PROFINET ring.
The primary CPU and the backup CPU execute the user program in parallel. If one CPU fails, the second CPU maintains control of the process.
If the PROFINET ring is interrupted, for example as a result of a cable break or an IO device
failure, redundancy in the ring is lost. However, the IO devices that have not failed continue
to operate and can be accessed.

관리 수준에서 마스터 PC는 제어 및 필드 수준에서 다양한 장치에 액세스합니다. 

마스터 PC는 산업용 이더넷을 통해 CPU에 연결됩니다.

제어 수준의 R-CPU는 설계가 중복됩니다.

현장 레벨의 IO 장치는 PROFINET 링 내의 R-CPU에 연결됩니다.

이중화 S7-1500R 시스템은 PN/PN 커플러를 통해 다른 PROFINET IO 시스템과 주기적으로 IO 데이터를 교환합니다.

PN/PN 커플러의 좌측은 S7-1500R 중복 시스템에 할당됩니다. 

PN/PN 커플러의 오른쪽은 CPU 1516-3 PN/DP(IO 컨트롤러)에 할당됩니다.

이 구성은 CPU 하나의 장애 또는 PROFINET 링의 중단을 허용합니다.

기본 CPU와 백업 CPU는 사용자 프로그램을 병렬로 실행합니다. 

하나의 CPU에 장애가 발생하면 두 번째 CPU는 프로세스의 제어권을 유지합니다.

PROFINET 링이 중단되면, 예를 들어, 케이블이 끊어지거나 IO 장치가 고장 나면 링 내의 중복성이 손실됩니다. 

그러나 장애가 발생하지 않은 IO 장치는 계속 작동하며 액세스할 수 있습니다.
