Setting Up Trending
Trending is a diagnostic tool that you can use to capture and retain an
input parameter data value until a trigger condition occurs. The RGU
has the capacity to setup and monitor up to 4 parameters, Trend 1
through Trend 4. With trending, you program the:
• parameter to sample
• trigger condition
• sampling rate
• quantity of samples to be taken after the trigger occurs
• whether trending is to occur one time or continuously
Parameters used by trending are shown in the table below.
