HIMA F3108 17039通用电气卡件
值设置为16位整数的符号扩展。此符号扩展的高位字允许在逻辑中将16位整数读取为32位整数类型，而不丢失整数的符号。如果16位整数结果为负，则32位通道数据中的高位字具有值0xFFFF。如果16位整数结果为正，则高位字为0x0000。PACSystems*RX3i系统手册第10节GFK-2314T 2019年9月模拟输入模块421 9.11.2.1分辨率和范围类型：ALG608和ALG616每个输入的实际分辨率取决于为该信道配置的范围类型和A/D滤波器频率。在较高的滤波器频率下，输入分辨率降低。下表显示了每个滤波器频率和范围类型的近似分辨率（以位为单位）。分辨率（位）滤波器频率范围类型±10 Vdc 0至10 Vdc、±5 Vdc、±20 Vdc 0至5 Vdc、1至5 Vdc，0至20mA、4至20mA 8 Hz 18 17 16 12 Hz 17 16 16 16 Hz 17 16 15 40 Hz 16 15 14 200 Hz 15 14 13 500 Hz 14 13 12 9.11.2.2信道扫描：ALG608和ALG616这些模块使用4个A/D转换器实现最快的信道扫描时间。该模块最多有四个采集周期手册第10节GFK-2314T 2019年9月模拟输入模块422 9.11.2.3信道诊断数据：ALG608和ALG616除了来自现场设备的输入数据外，该模块还可以配置为向CPU报告信道诊断状态数据。CPU将此数据存储在为模块配置的诊断参考地址中。此功能的使用是可选的。每个通道的诊断数据占用两个通道：报警或故障条件不存在或该通道的配置中未启用检测。对于每个通道，此数据的格式为：PACSystems*RX3i系统手册第10节GFK-2314T 2019年9月模拟输入模块423 PACSystems*RX3i系统说明书第10节GFK-2314T2019年9月份模拟输入模块424 9.11.2.4模块状态数据：ALG608和ALG616模块也可选择配置为向CPU返回两位模块状态数据。CPU将此数据存储在为模块配置的32位模块状态数据参考区域中。9.11.2.4.1接线板检测模块自动检查是否存在接线板。TB LED指示模块接线板的状态。当接线板存在时，它是绿色的，如果没有，它是红色的。当从系统中配置的模块插入或移除接线板时，故障会自动记录在CPU I/O故障表中。故障类型为Field fault（现场故障），故障描述表明故障是“接线板丢失”还是“接线板增加”。如果在存储配置时不存在接线板，则会记录“接线板丢失”故障。模块状态参考的第1位指示接线板的状态。要启用模块状态报告，必须配置模块状态参考。运行期间，PLC必须处于I/O启用模式，以便在参考存储器中扫描和更新当前模块状态。9.11.3现场接线：ALG608和ALG616，单端模式下表列出了单端模式中非隔离模拟输入模块的接线连接。单端模式是配置的默认操作模式。端子IC695ALG608
value is set with the sign extension of the 16-bit integer. This sign-extended upper word allows the 16-bit integer to be read as a 32-bit integer type in logic without losing the sign of the integer. If the 16-bit integer result is negative, the upper word in the 32-bit channel data has the value 0xFFFF. If the 16-bit integer result is positive, the upper word is 0x0000. PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 421 9.11.2.1 Resolution and Range Types: ALG608 & ALG616 The actual resolution for each input depends on the Range Type and A/D Filter Frequency configured for that channel. At higher Filter Frequencies, input resolution decreases. The approximate resolution in bits for each Filter Frequency and Range Type are displayed in the following table. Resolution (in bits) Filter Frequency Range Type ±10 Vdc 0 to 10 Vdc, ±5Vdc, ±20 Vdc 0 to 5Vdc, 1 to 5Vdc, 0 to 20mA, 4 to 20mA 8 Hz 18 17 16 12 Hz 17 16 15 16 Hz 17 16 15 40 Hz 16 15 14 200 Hz 15 14 13 500 Hz 14 13 12 9.11.2.2 Channel Scanning: ALG608 & ALG616 These modules use 4 A/D converters to achieve the fastest possible channel scan times. The module has up to four acquisition cycles Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 422 9.11.2.3 Channel Diagnostic Data: ALG608 and ALG616 In addition to the input data from field devices, the module can be configured to report channel diagnostics status data to the CPU. The CPU stores this data at the Diagnostic Reference Address configured for the module. Use of this feature is optional. The diagnostics data for each channel occupies two the alarm or fault condition is either not present or detection is not enabled in the configuration for that channel. For each channel, the format of this data is: PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 423 PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 424 9.11.2.4 Module Status Data: ALG608 & ALG616 The module can also optionally be configured to return two bits of module status data to the CPU. The CPU stores this data in the 32-bit Module Status Data reference area configured for the module. 9.11.2.4.1 Terminal Block Detection The module automatically checks for the presence of a Terminal Block. The TB LED indicates the state of the terminal block of the module. It is green when the Terminal Block is present or red if it is not. Faults are automatically logged in the CPU I/O Fault table when the terminal block is inserted or removed from a configured module in the system. The fault type is Field Fault and the fault description indicates whether the fault is a "Loss of terminal block" or an "Addition of terminal block". If a Terminal Block is not present while a configuration is being stored, a "Loss of terminal block" fault is logged. Bit 1 of the Module Status Reference indicates the status of the terminal block. To enable Module Status reporting, the Module Status Reference must be configured. During operation, the PLC must be in an I/O Enabled mode for the current Module Status to be scanned and updated in reference memory. 9.11.3 Field Wiring: ALG608 & ALG616, Single-Ended Mode The following table lists wiring connections for Non-Isolated Analog Input Modules in Single-ended mode. Single-ended mode is the configured default operating mode. Terminal IC695ALG608
