Sda Generates An Error While Opening Trend Files In Chart Display - Honeywell DPR180 Manual

6.9 SDA generates an error while opening trend files in chart display

CHECK DIAGNOSTIC / ACTION
1. An archived Math function has returned an error code
which prevents SDA from charting correctly this channel.
Open the trend file in the data table format and note the
math in error. Open the trend file in the trend format and
remove the math function in error from the list of selected
traces to be charted.
2. When the archiving process is incorrectly interrupted (ie :
power off while archiving), it may happen that SDA displays
an error message while opening the archive files. Files are
nevertheless still readable except for their last data part. It is
then recommended in that case to reduce the last time to
display in the SDA opening trend files window.
