AI6700 模拟输入模块在交流电压数字输出模块上，由OVD过程识别的故障开关导致TRICONEX DI6503输出信号转换到相反状态,大交流周期为1/2。 这转换可能并非对所有现场设备都是透明的。一旦检测到故障，模块TRICONEX DI6503停了OVD的进一步迭代。 如果受控过程需要，0VD 可以禁用，但必须定期循环到“开"和"关"状态，以确保100故障覆盖率百分比。
直流电压数字输出模块
直流电压数字输出模块专门]设计用于控制保持的设备长时间处于一种状态的点。直流电压数字输出的0VD策略TRICONEX DI6503模块确保完全覆盖故障，即使点的命令状态从未改变。上这种类型的模块，输出信号转换通常发生在OVD执行期间,但保证小于2.0毫秒(通常为500微秒)，姐对大多数现场设备。如果受控过程需要，可以禁用0VD,但必须定期循环到"开和”关”状态，以确保100%的故障覆盖率。
On the AC voltage digital output module, the fault switch identified by the OVD process causes the TRICONEX DI6503 output signal to transition to the opposite state, with a maximum AC cycle of 1/2. This conversion may not be transparent to all on-site devices. Once a fault is detected, module TRICONEX DI6503 stops further iteration of OVD. If required by the controlled process, 0VD can be disabled, but it must be periodically cycled to the "on" and "off" states to ensure a 100% fault coverage rate.
DC voltage digital output module
The DC voltage digital output module is specifically designed to control the point where the device remains in a state for a long time. The 0VD strategy for DC voltage digital output of the TRICONEX DI6503 module ensures complete coverage of faults, even if the command state of the point has never changed. On this type of module, output signal conversion usually occurs during OVD execution, but is guaranteed to be less than 2.0 milliseconds (usually 500 microseconds), which is suitable for most on-site devices. If required by the controlled process, 0VD can be disabled, but it must be periodically cycled to the "on and" off "states to ensure 100% fault coverage.
