黑马F8628X F8652X安全CPU系统通讯SIS卡安全控制系统是专门用于危险场所（如：石油化工装置）联锁和紧急事故停车的控制系统。它和普通工艺过程控制的DCS和PLC的本质区别在于，其功能是在事故和故障状态下（包括装置事故和控制系统本身发生故障时），使装置能够安全停车，并处于安全状态下，从而避免灾难的发生，即避免对装置人员的伤害及对环境的影响等，因而安全控制系统本身必须是故障安全型（Fail to Safe）的，系统的硬件和软件的可靠性都要求很高。在国际安全标准IEC61508中，对安全等级及安全控制系统的要求具有详尽的规定。TÜV是目前世界上唯一的安全控制系统认证机构。自1970年HIMA公司首先推出TÜV认证的故障安全型安全控制系统HIMA-Planar-System起，安全控制系统已有三十年的发展史。

The Black Horse F8628X F8652X Safety CPU System Communication SIS Card Safety Control System is a control system specifically designed for interlocking and emergency shutdown in hazardous areas (such as petrochemical plants). The essential difference between it and ordinary process control DCS and PLC is that its function is to enable the device to safely stop and be in a safe state in case of accidents and faults (including device accidents and control system failures), in order to avoid the occurrence of disasters, such as injury to device personnel and impact on the environment. Therefore, the safety control system itself must be a fail to safe type, The reliability of both the hardware and software of the system is highly required. In the international safety standard IEC61508, there are detailed regulations on the requirements for safety levels and safety control systems. T Å V is currently the only safety control system certification body in the world. Since HIMA Company first launched the T Å V certified fail safe safety control system HIMA Planar System in 1970, the safety control system has a development history of thirty years.
