Enter the command TBUP followed by a digital signal e.g. M10. The digital signal
can now be connected to a function or touch key. When the digital signal is activated
from the key, all trend files (unless the TBS command is also used) from the operator
panel’s project memory will be backed-up on the external memory card. During the
backup, trend sampling is disabled. When the backup is finished, the operator panel
will reset the digital signal specified on the commands line.
There is also an error indication linked to the TBUP command, to the digital signal
that follows the TBUP signal (TBUPx + 1). This bit will be set if something goes
wrong during backup; for example if no memory card is inserted or if the memory
card is write protected.
TMBx Trend Multi Backup. Used together with the system command TBUP to cre-
ate more backup libraries on the backup card (x is the number of libraries
with backup files on the card. When the defined number is exceeded, the
oldest library is replaced. Default value is 1).
Note:
On an external memory card, only one version of a trend can be stored in each library.
If a trend which already exists on the memory card is backed up, the trend will be de-
leted and replaced by the new trend. Create more libraries with the command TMBx.
