2.产 品 详 情 资 料：
SAIA PCD2.M120在用户程序内，通过构建模块H8-STA-3，最多可将10个可测试输出模块分配给一个组。3） 关闭相关CU的WD在这种情况下，将关闭相关中央模块的看门狗信号（WD）。如果使用具有冗余中央模块和公共I/O总线的系统，则输出模块与两个中央模块相关。如果出现故障，中央模块的两个看门狗信号都会关闭。这意味着所有I/O模块都将关闭。如果使用具有冗余中央模块和冗余I/O总线的系统，SAIA PCD2.M120则输出模块与一个中央模块和一个I/O总线相关。发生故障时，仅关闭相关中央模块的看门狗信号。这意味着仅关闭相关I/O模块。使用的缩写和符号：PS电源模块I/O输入/输出（模块/总线）CU中央模块SAIA PCD2.M120
Inside the user’s program up to 10 testable output modules can be assigned to one group by means of the building block H8-STA-3. 3) SAIA PCD2.M120Switch off WD of the appertaining CU In this case the watch dog signal (WD) of the appertain-ing central module will be switched off. If systems with redundant central modules and a common I/O bus are used then the output modules are related to both central modules. In case of a fault both the watchdog signals of the central modules are switched off. That means all the I/O modules are switched off. If systems with redundant central modules and redundant I/O bus are used then the output modules are related to one central module and one I/O bus. In case of a fault only the watch dog signal of the related central module is switched off. That means only the related I/O modules are switched off.Used abbreviations and signs: PS Power supply module I/O Input/output (module/bus) CU Central moduleSAIA PCD2.M120
