2.產(chǎn) 品 詳 情 資 料：
SAIA PCD2.M120在用戶(hù)程序內(nèi)，通過(guò)構(gòu)建模塊H8-STA-3，最多可將10個(gè)可測(cè)試輸出模塊分配給一個(gè)組。3） 關(guān)閉相關(guān)CU的WD在這種情況下，將關(guān)閉相關(guān)中央模塊的看門(mén)狗信號(hào)（WD）。如果使用具有冗余中央模塊和公共I/O總線(xiàn)的系統(tǒng)，則輸出模塊與兩個(gè)中央模塊相關(guān)。如果出現(xiàn)故障，中央模塊的兩個(gè)看門(mén)狗信號(hào)都會(huì)關(guān)閉。這意味著所有I/O模塊都將關(guān)閉。如果使用具有冗余中央模塊和冗余I/O總線(xiàn)的系統(tǒng)，SAIA PCD2.M120則輸出模塊與一個(gè)中央模塊和一個(gè)I/O總線(xiàn)相關(guān)。發(fā)生故障時(shí)，僅關(guān)閉相關(guān)中央模塊的看門(mén)狗信號(hào)。這意味著僅關(guān)閉相關(guān)I/O模塊。使用的縮寫(xiě)和符號(hào)：PS電源模塊I/O輸入/輸出（模塊/總線(xiàn)）CU中央模塊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
