Using the Maestro Software to
Log Parameters
Introduction
This section covers the procedure used to set up or change parameter
logs, and establish the frequency the parameters are logged.
Parameter logs are used to create an historical graph of the parameter
values over a period of time. The ACT2 controller can log each input
and output 500 times. When 500 log entries have been stored, the
oldest entry is dropped when the next new log entry is recorded. These
logs are viewable either on the ACT2 controller panel or with the
Maestro software. See
Using the Maestro Software to View System
Information for instructions on how to view logs.
