HONEYWELL CC-TDOB01称重模块,CC-TDOB01使用方法教程
8点隔离模拟电压源输出模块执行诊断并提供
向BIU发送24位（3字节）诊断数据。CC-TDOB01数据放置在BIU的离散输入（I）数据中
表从配置的引用开始。模块设置此数据的适当位
当检测到诊断条件时。诊断位保持设置，直到
适当的数据输出，如下所述。导致故障的条件必须为
已更正，否则模块将再次设置位。
此数据的使用是可选的。模块可以轻松配置为使用
诊断数据。清除故障和警报
BIU使用两个字节的离散输出数据来清除模块故障和报警位。这个
故障清除位从BIU中模块配置的离散输出参考开始
离散输出（Q）表。
将离散输出数据的第一个字节中的一位设置为1将清除超/欠范围报警
对于相应的通道（即使报警条件仍然存在）。
模块诊断字节中的位#0–2、4和6与校准相关，不应
在正常运行期间设置。HONEYWELL CC-TDOB01称重模块不能使用离散输出（Q）数据清除这些位。
如果在正常操作期间（而非校准期间）设置了这些位中的任何一位，则存在问题
并且应该返回模块。
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.
