Symbol bar: see above, horizontal axis, additionally there is a "home" button for
restoring the standard settings concerning zooming and offset of the axes.

time dependent behaviour of the variable values will be displayed using the chosen
range of the scale, or whether the record should be saved to history file, which can be

configured after pressing the button History. The dialog corresponds to that which is
used for the configuration of the alarm log file.

defined here will be ignored and the log file will be stored in the download directory
of the PLC.

the name and the values of all regarded variables. Each line starts with a unique
identifier in DWORD format, which is built from the date of measuring.

Choose variable: Press this button to get the dialog Variables, where you can
configure the variables for which the trend record should be done and how they
