Minimum Logic Block

Description

Minimum Logic Blocks are used to keep track of the all-time minimum of a particular trend log.

• Note that this minimum does not need to appear within your viewable data, as it is the all-time minimum for the entire set of data for the Trend Log

Applications include:

• Keeping track of minimum temperature to estimate maximum heating costs
• Monitoring pH level of sewage water

Functionality

The output of a Minimum Logic Block is a data series such that:

• Timestamps are identical to that of input data series
• All values are equal to the minimum value among all the data points of the input data series
