- 1 minute read
The value of Pen_ROCPercentMax sets an absolute percent rate of change between consecutive measured values shown by the SA_Trend_SinglePen symbol. The symbol shows a ROC arrow symbol next to the meter at the right margin of the trend grid.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.
