6.4 Backup of Trend Data
It is possible to copy trend data files from the ordinary project memory in the oper-
ator panel to an external memory card placed in the operator panel. Not available for
E1022. The memory card in the operator panel must be formatted as a backup card.
It can then be accessed in the operator panel via FTP, or brought to an arbitrary op-
erator panel, to upload trend data via FTP transfer from the memory card to a PC
for further processing. Trend files which have been backed-up can be found in the
catalog (library) “backup” in the operator panel’s catalog structure. To read/write
trend data files from/to the operator panel to the PC, there must be a FTP client pro-
gram installed on the PC e.g. HMI Tools FTP Client program.
Backup of trend files from the operator panel’s project memory to the external mem-
ory card placed in the operator panel is done with the help of the command TBUP
and a memory cell entered on the command line in the configuration tool. Double-
click on System Signals under the Setup folder in the Project Manager.
TBUP Trend Backup. Used for backup copy of trend files on external memory card.
TESOSn Storage of one trend sample only when the signal Activate is set to 1. If n=*,
all trend objects are affected. If n=T, only trend objects that begin with T
are affected.
TBS The command is to be followed by one character that indicates which trends
or data loggers that are to be copied to the external memory card. Only
trends and data loggers that begin with this character will be copied when
the TBUP signal is set.
