HIMA F1202处理器模块
–3V（最小值）至Vuser（最大值）有关产品标准和一般规范，请参阅附录A.64在存在严重RF干扰（IC 801-3，10V/m）的情况下，精度可能会降低到±1%FS。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块452 10.3.12.1热降额，电流模式：ALG708模块IC695ALG704没有热降额。模块IC695ALG008在电压模式下没有热降额。电流模式下模块IC695ALG008的热降额如图305所示。图305：ALG708在选定电压水平下的热降额曲线（仅限电流模式）10.3.13配置：ALG704和ALG708 10.3.13.1模块参数参数默认描述输出参考地址%AQxxxxx此模块输出数据的起始地址。这默认为下一个可用的%AQ块。输出参考长度ALG004:8用于此模块输出数据的单词数。无法更改此参数。ALG708:16输出命令反馈参考地址%AIxxxxx此模块命令反馈数据的说明地址。配置非零长度后，默认为下一个可用%AI地址。输出命令反馈长度0用于此模块的命令反馈数据的单词数。长度默认为0。它可以设置为8或16，具体取决于所配置的模块类型。诊断参考地址%Ixxxxx通道诊断状态数据的起始地址。这默认为下一个可用的%I块。50 51 52 53 54 55 56 57 59 60 1 2 3 4 5 6 7 8环境（摄氏度）通道Vuser=26.5V此模块的状态数据短路。这默认为下一个可用的%I块。模块状态参考长度0只读。模块状态数据所需的位数（0或32）。默认值为0，这意味着模块状态数据的映射被禁用。将其更改为非零值以启用模块状态数据映射。10.3.13.1.1模拟输出命令反馈模块将从CPU接收的模拟输出数据的副本返回到其相应的通道模拟输入共享存储器中。可以监控输出反馈，以检查发送到通道的值。数据采用与每个通道的输出数据相同的缩放格式。在正常操作期间，该反馈数据应与模块输入的一次或多次PLC扫描后的实际输出数据相匹配。在故障、斜坡、超范围和箝位条件下，模拟输出数据可能与命令输出不同。10.3.13.1.2过高温度如果启用了过高温度，如果该模块的内部温度对于同时打开的输出数量而言过高，则模块会生成过高温度警报。
– 3V (minimum) to Vuser (maximum) For product standards and general specifications, refer to Appendix A. 64 In the presence of severe RF interference (IC 801-3, 10V/m), accuracy may be degraded to ±1% FS. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 452 10.3.12.1 Thermal Derating, Current Mode: ALG708 Module IC695ALG704 has no thermal derating. Module IC695ALG708 has no thermal derating in voltage mode. Thermal derating for module IC695ALG708 in current mode is displayed in Figure 305. Figure 305: Thermal Derating Curves for ALG708 at selected Voltage Levels (Current Mode only) 10.3.13 Configuration: ALG704 and ALG708 10.3.13.1 Module Parameters Parameter Default Description Outputs Reference Address %AQxxxxx Starting address for the output data of this module. This defaults to the next available %AQ block. Outputs Reference Length ALG704: 8 The number of words used for the output data of this module. This parameter cannot be changed. ALG708: 16 Output Command Feedback Reference Address %AIxxxxx Stating address for the command feedback data of this module. This defaults to the next available %AI address after a non-zero length is configured. Output Command Feedback Length 0 The number of words used for the command feedback data of this module. Length defaults to 0. It can be set to 8 or 16, depending on the module type being configured. Diagnostic Reference Address %Ixxxxx Starting address for the channel diagnostics status data. This defaults to the next available %I block. 50 51 52 53 54 55 56 57 58 59 60 1 2 3 4 5 6 7 8 Ambient (Degrees C) Channels Vuser = 26.5V Shorted the status data of this module. This defaults to the next available %I block. Module Status Reference Length 0 Read Only. The number of bits (0 or 32) required for the Module Status data. Default is 0, which means mapping of Module Status data is disabled. Change this to a non-zero value to enable Module Status data mapping. 10.3.13.1.1 Analog Output Commanded Feedback The module returns a copy of the analog output data received from CPU in its corresponding channel analog input shared memory. Output Feedback can be monitored to check the values being sent to the channels. The data is in the same scaled format as the output data for each channel. During normal operation, this feedback data should match the actual output data after one or more PLC scans of module inputs. During faults, ramping, over-range, and clamping conditions, the analog output data may differ from the commanded output. 10.3.13.1.2 Over-Temperature If Over-Temperature is enabled, the module generates an Over-Temperature alarm if the internal temperature of this module is too great for the number of outputs that are on at the same time.
