Analog min max limiter
This program block allows analogue values to be limited between a certain range
The parameters Min and Max define the minimum and maximum limits of the range of allowable values.
Connect an analogue input (such as a temperature sensor) to the input AI on the block. If the value at input AI is less than Min then the value set at Min is output at AQ.
Likewise if the analogue value is greater than Max then the value set at Max is output at AQ.
If the value is between the two limits then the value at AI will be output at AQ.
Temperature limiting for a hot water tank etc.
