This section covers Digital Values to Log, Integer Values to Log, Float Values to Log and Int32 Values to Log. Each set of settings allows you to choose up to 32 values of the designated type (digital, 16 bit signed integer, single precision floating point or 32 bit signed integer) to Log.
Each logged value can be named independently via the group instance name setting. For all values, choose a Modbus register to read the value from. Floating point values and 32 bit integers will need two registers.
For integer and floating point values, it is possible to select a function to apply to the raw data before the data is logged. The possible options are None, Minimum, Maximum and Average. Each option is discussed below.
None. No function is applied. The last sample collected before data is logged is entered in the log.
Minimum. The minimum value of all samples is logged. The minimum value is reinitialized (cleared) every time that data is logged. A sample is collected every 5 seconds.
Maximum. The maximum value of all samples is logged. The maximum value is reinitialized (cleared) every time that data is logged. A sample is collected every 5 seconds.
Average. A simple moving average of all samples is logged. The average is reinitialized (cleared) every time that data is logged. A sample is collected every 5 seconds. Long averaging periods with floating point and 32 bit integer values will result in a loss of precision.
