System Variables
System variables can be used to control terminal-internal functions.
System variables can be referenced to function keys and soft keys. They can also
be used in masks as normal variables for input and output processes.
The following applies if a system variable is linked to a function key or soft key:
-
do not link a change of mask function and a system variable to the same key
-
it is not necessary that the same function key or soft key is used to set (1) and
reset (0) a system variable
-
jogging mode is obtained by using the same function key or soft key to set (1)
and reset (0) a system variable.
Do not include the names of system variables in the variable list. If the name of a
system variable is referenced to a PLC address, it will loose its terminal-internal
function.
The following subchapters list the system variables, organized into separate
groups of functionality, and describes their functions.

Basic Functions
IntEraseEprom
Allows the user description to be erased from the Flash memory and prepares the
terminal for a new download via interface channel SER2. There will be no commu-
nication with any connected PLC during this process. Writing of a ‘1’ to this variable
erases the user description unconditionally. Subsequently, the variable is automat-
ically reset to ‘0’.
