3.1.4 Monitoring the GX/GP Data
You can retrieve data and display conditions from the GX/GP and view the information using
the monitors listed below.
Monitors Trend, digital, bar graph, overview, alarm summary, message summary, error log,
network information, system information, and favorite monitor
On the trend monitor, you can display the trends of up to four groups. On the digital and bar
graph monitors, you can display digital data and bar graphs of up to four groups.
The favorite monitor can display a combination of up to four monitors on one screen. You
can select from the trend, digital, bar graph, overview, alarm summary, message summary,
and error log monitors. This is a separate function from the favorite screen registration
function on the GX/GP.
Display Update Interval
The channel data display is updated at the scan interval. However, the shortest update
interval is 1 second.
Order of Display Precedence
If the display of the same type of items overlaps, the information of the smallest number
takes precedence. For example, if multiple alarms are occurring, the alarm with the smallest
alarm level number takes precedence.
Note

may not display data correctly. In such a case, reload the page.
