HIEE300900R0001处理控制模块,HIEE300900R0001说明书在线阅读
电流范围默认范围为4至20 mA，用户数据按比例缩放，使4 mA对应于0和0的计数20 mA对应32000计数。通过更改使用IC641配置器软件或手持式编程器的配置参数。可以配置范围，使输入范围为0至20 mA，用户数据缩放为0mA对应于0的计数，20 mA对应于32000的计数。全12位分辨率在4至20和0至20 mA范围内可用。也可以选择4到20 mA的增强范围。
HIEE300900R0001处理控制模块当选择该范围时，0 mA对应对于–8000的计数，4 mA对应于0（零）的计数，20 mA对应于+32000。增强范围使用与0至20 mA范围相同的硬件，但自动提供4至20 mA范围缩放，但提供负数字值的情况除外用户输入电流水平在4 mA和0 mA之间。这使您能够选择低报警限值，检测输入电流从4 mA降至0 mA的时间，这提供4至20 mA应用中的开路故障检测。报警上限和下限为适用于所有范围。可以基于每个通道配置范围。该模块还报告CPU的模块状态和用户侧电源状态。电源要求和LED该模块从PLC背板上的5V总线消耗120 mA，也需要65 mA加上用户提供的+24V电源的电流回路电流（见表3-13，规格）。
HIEE300900R0001处理控制模块模块上有两个绿色LED指示灯，用于提供模块和用户电源地位顶部LED，MODULE OK（模块正常）在通电时提供模块状态信息，如下所示：跟随：开启：状态正常，模块已配置；关闭：没有背板电源或软件未运行（看门狗计时器超时）；连续快速闪烁：未从CPU接收到配置数据；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电源在从而使模块的模拟侧能够正常工作
Current Ranges
The default range is 4 to 20 mA with user data scaled so that 4 mA corresponds to a count of 0 and
20 mA 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 0 to 20 mA with user data scaled so that 0
mA corresponds to a count of 0 and 20 mA corresponds to a count of 32000. Full 12-bit resolution
is available over the 4 to 20 and 0 to 20 mA ranges.
A 4 to 20 mA Enhanced range can also be selected. When this range is selected, 0 mA corresponds
to a count of –8000, 4 mA corresponds to a count of 0 (zero) and 20 mA corresponds to a count of
+32000. The Enhanced range uses the same hardware as the 0 to 20 mA range but automatically
provides 4 to 20 mA range scaling with the exception that negative digital values are provided to
the user for input current levels between 4 mA and 0 mA. This gives you the capability of
selecting a low alarm limit that detects when the input current falls from 4 mA to 0 mA, which
provides for open-wire fault detection in 4 to 20 mA applications. High and Low alarm limits are
available on all ranges. Ranges can be configured on a per channel basis. The module also reports
module status and user-side supply status to the CPU.
Power Requirements and LEDs
This module consumes 120 mA from the 5V bus on the PLC backplane and also requires 65 mA
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 information on power-up as
follows:
ON: status is OK, module configured;
OFF: no backplane power or software not running (watchdog timer timed out);
Continuous rapid flashing: configuration data not received from CPU;
