OKUMA BDU-75A自动化工控设备

产品详细资料
此操作为所有组件提供100%的故障检测，特别是那些长时间保持单一状态的组件。例如，如果输出始终处于开启状态，OVD无法确定是否存在会阻止输出关闭的故障。程序1确保受控过程关闭。（不要停止控制程序的运行。）2在TriStation 1131中，转到控制器面板>命令菜单，启用禁用的OVD模块。3将OVD保持启用状态几分钟，以验证模块的稳定性。4如果需要，禁用OVD。警告对于安全程序，不建议禁用输出表决器诊断；然而，如果由于过程干扰问题而需要，则只有在每三到六个月对DO进行一次验证测试的情况下才能进行。切换现场I/O点为了确保表94中列出的模块中的数字电路的完全故障覆盖，执行以下操作：•将场点从正常操作状态切换到相反状态（这是通过“强制”点来完成的）。•让每个点处于相反的状态几分钟。•切换字段点的频率至少与模块规范中确定的小切换速率相同。
This action provides 100 percent failure detection for all components, particularly those that remain in a single state for long periods of time. For example, if an output is always On, OVD cannot determine if faults are present that would prevent the output from being turned Off. Procedure 1 Ensure the controlled process is shut down. (Do not stop the control program from running.) 2 In TriStation 1131, go to the Controller Panel > Commands menu and enable the disabled OVD modules. 3 Leave OVD enabled for several minutes to verify the stability of the modules. 4 If required, disable OVD. WARNING For safety programs, disabling the Output Voter Diagnostics is not recommended; however, if it is required due to process interference concerns, it can be done if, and only if, the DO is proof tested every three to six months.Toggling Field I/O Points To guarantee complete fault coverage of the digital circuitry in the modules listed in Table 94, do the following: • Toggle the field points from the normal operational state to the opposite state (this is done by “forcing” the points). • Leave each point in the opposite state for several minutes. • Toggle the field points at least as frequently as the Minimum Toggle Rate identified in the specifications for the module.
