ABB PM857K02 3BSE088386R1逻辑控制器
产品详情资料：
ABB PM857K02 3BSE088386R1逻辑控制器CPU 板包含微处理器和 RAM 存储器、实时时钟、LED 指示灯、INIT 按钮和 CompactFlash 接口。PM857 控制器的底板有两个 RJ45 以太网端口（CN1、CN2）用于连接到控制网络，以及两个 RJ45 串行端口（COM3、COM4）。其中一个串行端口（COM3）是带有调制解调器控制信号的 RS-232C 端口，而另一个端口（COM4）是隔离的，ABB PM857K02 3BSE088386R1用于连接配置工具。控制器支持 CPU 冗余以提高可用性（CPU、CEX-Bus、通信接口和 S800 I/O）通过添加 SM812 模块和 SIL 认证软件可实现高完整性功能。这使得非关键控制方案能够通过添加插件 SM81x 模块以及选择合适的软件升级为 SIL 认证方案。AC 800M High-Integrity 还提供 IEC 61508 和 TÜV 认证的控制环境，用于在一个控制器单元中结合安全和关键业务过程控制，而不会牺牲安全完整性 PM857 最多可以处理 128 个 I/O 信号。通过 SIL3 认证。需要根据安全手册进行配置 ABB PM857K02 3BSE088386R1包装包括：
2 个 PM857K01，安全处理器单元
1 个 TK850，CEX 总线扩展电缆
1 个 TK851，RCU-Link 电缆

英文资料：
ABB PM857K02 3BSE088386R1 logic controller CPU board contains microprocessor and RAM memory, real-time clock, LED indicator, INIT button and CompactFlash interface. The backplane of the PM857 controller has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, and two RJ45 serial ports (COM3, COM4). One serial port (COM3) is an RS-232C port with modem control signal, while the other port (COM4) is isolated and used to connect the configuration tool. The controller supports CPU redundancy to improve availability (CPU, CEX-Bus, communication interface and S800 I/O). The high integrity function can be achieved by adding SM812 module and SIL authentication software. This enables non-critical control schemes to upgrade to SIL certification schemes by adding SM81x modules and selecting appropriate software. AC 800M High-Integrity also provides IEC 61508 and T ≠ V certified control environment, which is used to combine safety and critical business process control in a controller unit without sacrificing safety integrity. PM857 can process up to 128 I/O signals. Passed SIL3 certification. The package shall be configured according to the safety ABB PM857K02 3BSE088386R1manual, including:
ABB PM857K02 3BSE088386R1Two PM857K01, security processor unit
1 TK850, CEX bus expansion cable
1 TK851, RCU-Link cable
