模拟组合I/O模块12-7 CPU接口至IC693ALG442模拟组合模块90-30系列PLC使用%AI和%AQ数据表中的数据记录模拟值,供可编程控制器使用。有关模拟模块CPU接口的详细信息,请参阅本章开头的“模拟模块硬件说明”一节。状态报告模拟组合模块模块向PLC提供状态信息。该状态信息在每次PLC扫描后更新,由以下项目组成:模块健康(所有范围)过载或断线检测(仅限电流输出模式)报警用户向模块供电的低和高状态(输入通道)状态(所有范围逻辑侧。模块的模拟电源必须由单个用户提供的+24 VDC电源供电。这包括电流回路输出功率和电压输出负载功率。此用户电源需要Analog Combination I/O Module 12-7 CPU Interface to the IC693ALG442 Analog Combo Module The Series 90-30 PLC uses the data within the %AI and %AQ data table to record analog values for use by the programmable controller. For detailed information on the CPU interface to analog modules, refer to the “Hardware Description of Analog Module” section at the beginning of this chapter. Status Reporting The Analog Combo module module provides status information to the PLC. This status information is updated once each PLC sweep and consists of the following items: health of the module (all ranges) overload or open wire detect (current output mode only) alarm low and high status (input channels) status of the user-supplied power to the module (all ranges) Power Requirements and LEDs This module requires a maximum of 95 mA from the 5V bus on the PLC backplane for the logic side. The module’s analog power must be supplied by a single, user supplied+24 VDC power source. This includes current loop output power and voltage output load power. This user supply requires
