RELIANCE 57405控制板
所有輸入類型都經過工廠校準，不需要現場校準。然而，對于輸出必須進行調整以滿足當地標準，現場校準功能可用于替代工廠校準對于所選的輸入類型。保留出廠校準，以便將輸入返回出廠
通過在校準選擇中存儲“FAC”，隨時進行校準。表3.5提供了以下輸入值：用于執行現場校準。校準期間，驗證模式可用于通過查看傳感器輸入全范圍。在校準驗證模式下查看的信號采用基本測量單位（例如，°C溫度，毫伏的mv），并且不受溫度單位轉換、數字濾波器、縮放或輸出偏置調整?？梢栽诓榭茨Ｊ较虏榭磻昧诉@些參數的完整塊輸出循環內配置。在熱啟動、熱啟動或冷啟動期間，功能塊將暫時旁通數字濾波器，使輸出能夠在實際硬件輸入信號處初始化。請注意，現場校準為：更改傳感器類型時將被擦除。3.2.11 AIP_-模擬輸入水平百分比AIP_功能塊轉換模擬信號

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.
