Overview of Analog Slaves Section 7-1
Analog processing is performed according to the following flowchart.
7-1-5 Selecting Data (Analog/Temperature Input Terminals)
After performing math operations, select up to two of the six resulting values
to allocate in the Master, from the analog/temperature input value, peak value,
bottom value, top value, valley value, and rate of change. The selected data is
referred to as “analog data” or “temperature data,” and can be allocated in the
Master individually or in combination with Status Flags. The data is selected
using the Configurator or explicit messages. For Analog Data 1 or Tempera-
ture Data 1, comparison operations with four alarm set values can be per-
formed (comparator function).
