A wide variety of predefined meters, bargraphs, buttons, and switches are available for insertion on an OIS
development screen. User defined bitmap images can be imported into the OISetup32 software and used
just like predefined buttons and switches.

2. Historical Trending: Historical trending is simple trending plus data logging. With historical trending the
data values are saved to the OIS internal memory. When to start and stop trending is user defined. What to
do when OIS memory is fully (stop or overwrite) is user defined. In the data logger 4 groups can be defined,
each group containing up to 32 tags. When to start logging and stop logging is user definable for each group.
Multiple trending windows can be displayed but each window is limited to 4 tags.

Trending is an important requirement in most
process applications and many machine control
applications. Displaying trends graphically
provides easier interpretation of process/system
change. Two types of trending are available in
the OIS60 and 0IS120.
1. Simple Trending: Variables are displayed
on the user defined screen. Variables are on
the Y-axis and time is on the X-axis. Time is
displayed in seconds / minutes by user
defined increments. The bar colors and the
number of grid lines are also user definable.
