RELIANCE 57405控制板
所有输入类型都经过工厂校准，不需要现场校准。然而，对于输出必须进行调整以满足当地标准，现场校准功能可用于替代工厂校准对于所选的输入类型。保留出厂校准，以便将输入返回出厂
通过在校准选择中存储“FAC”，随时进行校准。表3.5提供了以下输入值：用于执行现场校准。校准期间，验证模式可用于通过查看传感器输入全范围。在校准验证模式下查看的信号采用基本测量单位（例如，°C温度，毫伏的mv），并且不受温度单位转换、数字滤波器、缩放或输出偏置调整。可以在查看模式下查看应用了这些参数的完整块输出循环内配置。在热启动、热启动或冷启动期间，功能块将暂时旁通数字滤波器，使输出能够在实际硬件输入信号处初始化。请注意，现场校准为：更改传感器类型时将被擦除。3.2.11 AIP_-模拟输入水平百分比AIP_功能块转换模拟信号

All input types are factory calibrated and do not require field calibration. However, for those cases where outputs must be adjusted to meet a local standard, a field calibration feature is available to override the factory calibration for the input type selected. The factory calibration is retained so that the input can be returned to the factory calibration at any time by storing ‘FAC’ in the calibration selection. Table 3.5 provides the input values that are used to perform a field calibration. A verify mode is available during calibration to view the sensor input over the full range. The signal that is viewed, in the calibration verify mode, is in the basic units of measure (e.g. °C for temperature, mv for millivolts) and is not affected by the temperature units conversion, digital filter, scaling, or the output bias adjustment. The full block output with these parameters applied can be viewed in the VIEW mode within loop configuration. During a hot, a warm or a cold start, the function block will temporarily by-pass the digital filter to enable the output to initialize at the actual hardware input signal. Note that the field calibration is erased when the SENsor TYPE is changed.3.2.11 AIP_ - Analog Input lev_Percent AIP_ function blocks convert an analog signal with a lev-percent type SNVT (Standard Network Variable Type) received from the LonWorks network into a block output, scaled in engineering units, for interconnection to other function blocks within the controller. A maximum of 25 AIP_ blocks can be used, up to the limit of nodes allowed on the Lon network or the memory limit of the controller. Each use of the block will be assigned a unique station wide ID (e.g. AIP06). These blocks are available when the LonWorks option board is installed in a 352P, 353, or 354N controller. The input connection is established by ‘binding’ a network variable from the remote analog node to the network variable of the AIP_ function block. A 6-character ASCII value can be entered to identify the engineering units of the output signal. Output scaling (MINSCALE and MAXSCALE) is provided to establish an engineering range of choice. The number of the input network variable to the AIP block can be viewed in the configuration mode. This is useful when other devices need this for binding. The Output Range is a special data type that includes the MIN and MAX SCALE, the DPP, and the ENGUNITS that can be connected to other blocks with a Range (RG PTR) input. The block output QS indicates the quality status of the output signal O1 and will go high when the output is of bad quality. Bad quality usually indicates a loss of communications within the LonWorks network.
