Handling External Memory Devices
Writing to External Memory Devices
Different types of numeric and text data from the
C-more
touch panel can be stored on an
SD card or a USB memory device. Numeric data from Line Trend Graph and PID Faceplate
Trend Graph objects may be stored. Text data from Lookup Text and Multi-state Text
objects can also be stored.
Up to 16 objects may be configured in the C-more programming software to log data. Along
with the 16 object limit, available storage on the external memory device is subject to the
memory capacity of the SD card or USB memory device. One log file is created in a 24 hour
period for each object. Additionally logging data is initially stored in the buffer in the panel
MRAM and data is written to the external memory device:
• when 2kB of data is cached,
• when 20 records have been stored,
• periodically, once every 1 minute,
• when one of the “SYS Copy LogTo %device%” or “SYS %device% Eject” tags is turned on.
• when there is an email or FTP action
• when the System Screen is called
• when the panel date is changed
Memory Device Formatting
Memory Devices should be formatted according to the following guidelines to insure best
performance and integrity of logged data.
