12 12-8系列90–30 PLC I/O模块规格–2000年7月GFK–0898F使用的参考值和每个系统的大模块注意事项可以安装在系统中的IC693ALG442模拟组合模块的数量取决于可用的%AQ、%AI和%I参考值的数量。每个模块使用2%AQ参考和4%AI参考（取决于状态配置）以及8、16或24%I参考（取决于报警状态配置）。这些引用的数量取决于系统中CPU的类型。请参阅第8章中的“每个系统的大模拟模块数”表，以确定可为各种CPU型号安装多少模拟组合模块。IC693ALG442模拟组合I/O模块12 GFK–0898F2章–IC693ALGA442模拟混合I/O模块12-9 IC693ALG442模拟模块现场接线连接用户设备与此模块的连接通过安装在模块前部的可拆卸20端子接线板上的螺丝端子实现。实际终端
12 12-8 Series 90–30 PLC I/O Module Specifications – July 2000 GFK–0898F References Used and Maximum Modules per System Considerations The number of IC693ALG442 Analog Combo modules that can be installed in a system depends on the amount of %AQ, %AI, and %I references available. Each module uses 2 %AQ references and 4 %AI references (depending on status configuration) and 8, 16 or 24 %I references (depending on alarm status configuration). The number of these references is dependent on the type of CPU in your system. Please refer the the “Maximum Number of Analog Modules per System” table in Chapter 8 to determine how many Analog Combo modules can be installed for the various CPU models.
