10 GFK-0898F第10章–Alog输入模块10-27 Alog电流输入-16 IC693ALG223 16-Alog电流输出模块提供多达16个单端输入，每个单端输入能够将模拟输入信号转换为数字值，以便根据应用程序的需要使用。此模块提供三个输入范围：增强型电流范围默认范围是用户数据的缩放，使4对应于0的计数，20对应于32000的计数。通过使用IC641配置器软件或手持式编程器更改配置参数来选择其他范围。该范围可以被配置为使得输入范围具有缩放的用户数据，从而0对应于0的计数，20对应于32000的计数。在和范围内提供完整的12位分辨率。也可以选择增强范围。选择此范围时，0对应于–8000的计数，4对应于0（零）的计数，20对应于+32000的计数。增强型量程使用与量程相同的硬件，但自动提供量程缩放，但为4和0之间的输入电流电平向用户提供负数字值除外。这使您能够选择一个低报警限值，以检测输入电流何时从4降至0，从而在应用程序中提供开路故障检测。所有范围都有高报警限值和低报警限值。范围可以根据具体情况进行配置。模块还向报告模块状态和用户侧电源状态。电源要求和LED此模块消耗PLC背板上5V总线的120，还需要用户提供的+24V电源的65+电流回路电流（见表3-13，规格）。模块上有两个绿色LED指示灯，提供模块和用户电源状态。顶部LED，MODULE OK（模块正常）在通电时提供模块状态信息，如下所示：on：状态正常，模块已配置；OFF：背板电源或软件正在运行（看门狗计时器超时）；连续快速闪烁：从接收到配置数据t；缓慢闪烁，然后关闭：通电诊断失败或遇到代码执行错误。底部LED“用户电源正常”指示用户提供的24V电源在规格范围内，从而使模块的模拟侧能够正常工作。系统中的位置此模块可安装在Series 90-30 PLC系统中5或10插槽基板的任何I/O插槽中。10 10-28 Series 90-30 PLC I/O模块规格–使用的2000 GFK-0898F参考可以安装在系统中的16-Alog电流输入模块的数量取决于可用的%AI和%I参考的数量。每个模块使用1至16%的AI参考（取决于写入的数量）和8至40%的I（取决于报警状态配置）参考。可用的%AI参考值为：311型、313型和323型系统中64个，331型系统中128个，340型和341型系统中1024个，351型和352型系统中2048个。系统中可安装的16-Alog电流输入模块的数量为：311型、313型和323型系统中的4个331型系统中8个340型和341型系统中12个351型和352型系统中51个规划时
10 GFK-0898F Chapter 10 – Alog Input Modules 10-27 Alog Current Input - 16 IC693ALG223 The 16- Alog Current Input module provides up to 16 single-ended input s, each capable of converting an alog input sigl to a digital lue for use as required by your application. This module provides three input ranges: Enhanced Current Ranges The default range is with user data scaled so that 4 corresponds to a count of 0 and 20 corresponds to a count of 32000. The other ranges are selected by changing the configuration parameters using the IC641 configurator software or the Hand-Held Programmer. The range can be configured so that the input range is with user data scaled so that 0 corresponds to a count of 0 and 20 corresponds to a count of 32000. Full 12-bit resolution is ailable over the and ranges. A Enhanced range can also be selected. When this range is selected, 0 corresponds to a count of –8000, 4 corresponds to a count of 0 (zero) and 20 corresponds to a count of +32000. The Enhanced range uses the same hardware as the range but autotically provides range scaling with the exception that negative digital lues are provided to the user for input current levels between 4 and 0 . This gives you the capability of selecting a low alarm limit that detects when the input current falls from 4 to 0 , which provides for open- fault detection in applications. High and Low alarm limits are ailable on all ranges. Ranges can be configured on a per basis. The module also reports module status and user-side supply status to the . Power Requirements and LEDs This module consumes 120 from the 5V bus on the PLC backplane and also requires 65 plus current loop current(s) from a user supplied +24V supply (see Table 3-13, Specifications). There are two green LED indicators on the module which provide module and user supply status. The top LED, MODULE OK provides module status infortion on power-up as follows: ON: status is OK, module configured; OFF: backplane power or software t running (watchdog timer timed out); Continuous rapid flashing: configuration data t received from ; Slow flashes, then OFF: failed power-up diagstics or encountered code execution error. The bottom LED, User Supply OK, indicates that the user provided 24V supply is within specifications, thereby ebling the alog side of the module to work properly. Location in System This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system. 10 10-28 Series 90-30 PLC I/O Module Specifications – 2000 GFK-0898F References Used The number of 16- Alog Current Input modules which y be installed in a system depends on the amount of %AI and %I references ailable. Each module uses 1 to 16 %AI references (depending on the number of s ebled) and from 8 to 40 %I (depending on alarm status configuration) references. The ailable %AI references are: 64 in a Model 311, Model 313, and Model 323 system, 128 in a Model 331 system, 1024 in a Model 340 and 341 system, and 2048 in a Model 351 and Model 352 system.
