- Last UpdatedAug 06, 2024
- 1 minute read
The value of ROCPercentMax sets an absolute percent rate of change between consecutive measured values. The trend of recent measured values is represented by the upward or downward orientation of a ROC arrow symbol shown next to a symbol.When consecutive measured values exceed the ROCPercentMax percentage, the ROC arrow points upward or downward to indicate the trend of recent measured values.The default is 0 percent.
Also, when a measured value's rate of change exceeds the value of ROCPercentMax, a rate of change alarm occurs if ROC properties have been set for an object attribute.
