Using the Historical Trend Graph:
Steps to create a Historical Trend Graph are covered in Chapter 5 – Data Objects in the
section on Advanced Objects so they will not be repeated here. However, keep in mind

This is normal but we do recommend taking your HMC7000 ‘offline’ while
performing this operation. The time required to download varies depending
upon the total size of the Data Log file but please be aware that the download
time may take several minutes to complete.
o Insert the USB Flash drive into the USB Host port of the HMC7000. It makes no
difference if the HMC is powered up when you insert the drive.
Method 1: Configure a quick button (Set Bit) to turn On internal
memory bit S00037 (USB host menu trigger).
When the HMC displays the screen with this button, press it to
see:
Press ‘Yes’ and a number of messages will display as the
HMC7000 attempts to read the USB Flash Drive. Eventually, the
