L0130AD模擬量卡件
有五種操作模式：–32位計數器增量編碼器輸入–32位計數器，在通道A和通道B遞減
–32位計數器，添加通道A和B
–通道A、B和C三個獨立的16位計數器
–三個16位頻率計，用于通道A、B和C通過設置DIP選擇操作模式開關位于裝置后部。
計數器可以設置為檢測上升、下降或上升和下降邊緣。
4個二進制輸入用于計數器數據設置，7個二進制靜態輸入提供了輸出。
輸出的狀態由比較決定計數器和設定值以及計數方向
該裝置必須安裝在插入式底座ECZ上。e：當使用230 VAC或120 VAC版本時可使用內部24 VDC電源，前提是不大于50 mA時加載；如果是，外部必須使用24 VDC電源。
僅使用外部電源的0 VDC提供輸出不必連接到公共-如果輸出必須重置為0切斷電源。
如果負載是感應的，則公共-和0V端子必須連接在一起，以避免輸出電路內的過電壓二極管是內置的，但這會增加響應時間● 初始化配置并接線裝置后：–裝置在通電后自行初始化。
–初始化后，錯誤指示燈熄滅。–計數器、閾值重置為0和目標
窗口設置為2。位B0表示數據傳輸狀態，并被檢查為從中央單元發送參數和命令到計數器單元。位B1至B4表示二進制輸入的狀態。位B8至B14表示晶體管輸出的狀態。如果輸入有效關閉，則所有二進制輸出重置為0，但內部狀態B8-B14始終可用。
配置和診斷可通過訪問配置和診斷下面的單詞
B7：當機組溫度為太高了。所有輸出均重置為“O”。
B15：當計數器值超過最大值或當計數器頻率太高。
B8：指示計數器的模式操作（插入式底座上的DIP開關n°2）。
–B8=0模式32位（DIP開關n°2打開“on”）
–B8=1模式2 x 16符號位（DIP開關n°2打開“OFF”）
在模式下為2 x 16位。高位字代表低位字的正溢出或負溢出數。
高位字在上以正溢出遞增低級單詞從+32767到-32768的轉換。
以類似的方式，高位字在從低位單詞的-32768到+32767的轉換。
Five modes of operation are possible :
– 32 bit counter incremental encoder input
– 32 bit counter, incrementing on channel A and
decrementing on channel B
– 32 bit counter, addition of channels A and B
– Three independant 16 bit counters for channel A, B and C
– Three 16 bit frequency meters for channels A,B and C
The mode of operation is selected by setting the DIP
switches on the rear of the unit.
The counters can be set to detect rising, falling or rising
and falling edges.
4 binary inputs for counter data setting and 7 binary static
outputs are provided.
The status of the outputs is determined by the comparison
of the counter(s) and setpoint values and the count
direction.
The unit has to be mounted on a plug-in base ECZ.e : When using the 230 VAC or 120 VAC versions, the
internal 24 VDC supply can be used providing the
load if it is not greater than 50 mA ; if it is, an external
24 VDC power supply must be used.
The 0 VDC of an external power supply used only
to provide the outputs has not to be connected to
the common –, if the outputs have to be reset to 0
with a power off of this supply.
If the load is inductive,the common – and the 0V
terminals must be connected together to avoid
overvoltage within the output circuitry an free weeling
diode is built-in, this however increases the response
time.● Initialization
After configured and wired the unit :
– the unit initializes itself after power On.
– the error led goes out after initialization.
– the counters, the thresholds are reset to 0 and the target
window to 2.Bit B0 indicates the data transfer status and is checked to
sending parameters and commands from the central unit
to the counter unit.
Bits B1 to B4 indicate the status of the binary inputs.
Bits B8 to B14 indicate the status of the transistor outputs.
If the input valid is off, all binary outputs are reset to 0 but
the internal status B8 - B14 is always available.
Configuration and diagnosis
The configuration and diagnosis are accessed with the
following words.B7 : "OVERLOAD" is set when the temperature of the unit
is too high. All of then outputs are reset to "O".
B15 : "OVERFLOW" indicate a counter error , when the
counter value exceeds the maximun or when the counter
frequency is too high.
B8 : indicate the mode operation for the counter (DIPswitch n°2 on the plug in base).
– B8 = 0 mode 32 bits (DIP switch n° 2 on "ON")
– B8 = 1 mode 2 x 16 signed bits(DIP switch n° 2 on "OFF")
In the mode 2 x 16 bit. The high word represents the
number of positive or negative overflows of the low word.
The high word is incremented with a positive overflow on
the transition from + 32767 à – 32768 of the low word.
In a similar manner the high word is decremented on the
transition from – 32768 à + 32767of the low word.
