H51q的安全关闭概念
在安全相关PES H51q-MS、-HS、-HRS的系统描述中，显示了发生故障时的关机方法。根据故障位置，系统的反应是固定的，或者可以在用户程序中定义。通过功能块H8-STA-3激活紧急关闭的系统变量，在资源属性I/O参数中设置参数。系统变量概述，包括相应的错误代码，您可以在

表5：H51安全关闭的概念 Concepts of the Safety Switch-Off at H51q
In the system descriptions of the safety related PES H51q-MS, -HS, -HRS the ways for shutdown if a fault occurs are shown. Depending on the fault location the reactions of the systemsare fixed or they can be defined in the user program.Parameters are set– in the resource properties I/O parameter– by activating of a system variable for emergency shutdown– via function block H8-STA-3.An overview of the system variables including the corresponding error code you will find in the
operating system manual.
