Configuring Queries
You can set up queries to actively monitor parameters of a serial or Ethernet
device and store the obtained value into a variable for reuse in a control system
project.

lamp has been used to be able to estimate the remaining lifespan and plan for
replacement in advance.
1. In Database Generator, click
Edit
to enter the settings page for the
projector.
2. Add a command by clicking
and double-click the command column to
type the command of requesting for the cumulative lamp usage (hour).
Consult the user manual for the device to find out the operation command.
3. Set up a variable to store the queried value.
a) In the Message column, click
Edit
. The Edit Messages window
appears.
b) Click the
Script
tab and click
+Add Script
and name the script.
