HONEYWELL CC-TDOB01稱重模塊,CC-TDOB01使用方法教程
8點隔離模擬電壓源輸出模塊執行診斷并提供
向BIU發送24位(3字節)診斷數據。CC-TDOB01數據放置在BIU的離散輸入(I)數據中
表從配置的引用開始。模塊設置此數據的適當位
當檢測到診斷條件時。診斷位保持設置,直到
適當的數據輸出,如下所述。導致故障的條件必須為
已更正,否則模塊將再次設置位。
此數據的使用是可選的。模塊可以輕松配置為使用
診斷數據。清除故障和警報
BIU使用兩個字節的離散輸出數據來清除模塊故障和報警位。這個
故障清除位從BIU中模塊配置的離散輸出參考開始
離散輸出(Q)表。
將離散輸出數據的第一個字節中的一位設置為1將清除超/欠范圍報警
對于相應的通道(即使報警條件仍然存在)。
模塊診斷字節中的位#0–2、4和6與校準相關,不應
在正常運行期間設置。HONEYWELL CC-TDOB01稱重模塊不能使用離散輸出(Q)數據清除這些位。
如果在正常操作期間(而非校準期間)設置了這些位中的任何一位,則存在問題
并且應該返回模塊。
The 8 Point Isolated Analog Voltage-source Output Module performs diagnostics and provides
24 bits (3 bytes) of diagnostic data to the BIU. Data is placed in the BIU’s discrete input (I) data
table starting at the configured reference. The module sets the appropriate bit of this data
when a diagnostic condition is detected. Diagnostics bits remain set until cleared by the
appropriate data outputs, as described below. The condition causing the fault must be
corrected, or the module will set the bit again.
Use of this data is optional. The module is easily configured to use all, some, or none of the
diagnostic data.Clearing Faults and Alarms
The BIU uses two bytes of discrete output data to clear the module fault and alarm bits. The
fault-clearing bits start at the module’s configured discrete output reference in the BIU’s
discrete output (Q) table.
Setting a bit in the first byte of discrete output data to 1 clears the over/underrange alarms
for the corresponding channel (even if the alarm conditions are still present).
Bits #0–2, 4, and 6 in the module diagnostics byte are calibration-related and should never
be set during normal operation. These bits cannot be cleared using discrete output (Q) data.
If any of these bits is set during normal operation (not during calibration), a problem exists
and the module should be returned.
