6.3 Startup and shutdown performance of the modules

模块的启停性能

The input and output values are communicated on a cyclic basis between the I/O modules and CPU module of the process station. If no communication occurs for a configurable number of cycles, both sides register an interruption of the communication.

过程站的I/O模块和CPU模块之间的输入输出值以周期方式通讯。如果在一个可配置周期数内没有发生通讯，双方注册一次通讯中断。

 

In this case, the process station transmits a system error message to the operator station. The output modules adopt the safety values. The input data for input modules are also set to the configured safety values on the controller. Depending on the process requirements, the safety values can be configured to "Hold the last value" or to a particular value/status.

在此情况下，过程站发送系统错误消息给操作员站。输出模块采取安全值。输入模板的输入值同样设置为控制器配置的安全值。根据工艺需求，安全值可以配置为保持上一次数值或者特定的值/状态。

 

A process station warm start or cold start always leads to output of the safety values. For "Load whole station" and at resource Initialization/Overall reset, the output levels of the output modules go to zero current.

过程站暖启动或者冷启动经常导致输出安全值。加载全部站和资源初始化/全部清除重置，输出模板的输出零电流。
