产品详情资料

 则必须从HHM或CPU清除诊断。过热诊断（标准）如果模块内部温度超过100ºC，模块会发送一条过热信息并关闭电路以保护其内部电子设备。故障开关诊断（标准）对于输出，如果电路的开关状态与其命令状态不同，则报告故障开关。模块发送故障开关消息，识别故障电路。电路的逻辑状态设置为OFF。如果输出开关发生短路（或闭合）故障，当模块强制输出状态OFF时，电流不会中断。必须采取模块外部的措施来解决问题。在输入和输出配置电路上，检测到几个独立于输出状态的附加开关故障，并报告为故障开关故障。示例包括与模块内部微处理器的通信中断以及一些内部电源故障。请注意，在GMR应用程序中，Failed Switch的操作方式不同。有关详细信息，请参见GMR用户手册。开路诊断（标准）表示三态输入的电气（非机械）故障。如前所示，电路必须有一个无感电阻器，尽可能靠近实际干触点（如现场设备端子两端）。过载诊断（可配置）如果启用过载停机，模块将must be removed, then the diagnostic must be cleared from the HHM or the CPU. Overtemperature Diagnostic (standard) If the block’s internal temperature exceeds 100º C, the block sends an OVERTEMPERATURE message and turns off the circuit to protect its internal electronics. Failed Switch Diagnostic (standard) For an output, Failed Switch is reported if the circuit’s switch state is not the same as its commanded state. The block sends a FAILED SWITCH message identifying the failed circuit. The logic state of the circuit is set to OFF. If the output switch has failed shorted (or closed), current flow is not interrupted when the block forces the output state OFF. Action external to the block must be taken to remedy the problem. Several additional switch faults independent of the output state are detected and reported as Failed Switch faults on both input and outputconfigured circuits. Examples include loss of communications with the block’s internal microprocessor and some internal power supply faults. Note that in GMR applications, Failed Switch operates differently. See the GMR User’s Manual for details. Open Wire Diagnostic (standard) Indicates electrical (not mechanical) malfunctions on a tristate input. The circuit must have a non-inductive resistor placed as close as practical to the actual dry contacts (such as across the field device terminals), as shown previously. Overload Diagnostic (configurable) If Overload Shutdown is enabled, the block will
