The touch panel acts as a master interface to the remotely located PLC. As such, the touch panel polls the
PLC, which, in turn, polls the field devices for information. A wand is used on the screen to operate system
controls and/or move to additional screens.
A USB port (Figure 1) is located on the back of the display at the bottom. When a USB Drive (USB Memory
Stick) is installed, the display will automatically log to the drive where any alarms and/or faults have been
recorded by the PLC. The information is logged into a folder named ‘Log’ and named ‘Alarm_yymmdd.txt’
where yy is the year, mm is the month, and dd is the day. The files are written in text format.
