Mode Change; Functional Possibilities In The Individual Modes - Siemens SINUMERIK 808D Function Manual

● The block indicator is reset to the beginning of the relevant part program.
● All Reset alarms are deleted from the display.
● The reset is complete as soon as IS "Channel status Reset" (DB3300.DBX0003.7) is set.

10.2.2

Mode change

General
A changeover to another operating mode is requested and activated via the interface.
Note
The mode is not changed internally until the IS "Channel status active" (DB3300.DBX0003.5) is no longer present.
In the "Channel status Reset" (IS: DB3300.DBX0003.7, e.g. after pressing the "Reset key") one can switch from any
operating mode into another.
In the "Channel status interrupted" (IS: DB3300.DBX0003.6) only a conditional changeover is possible (see following table).
If one leaves AUTO to change to JOG, one must return to AUTO again or press "Reset". Thus a change AUTO-JOG-MDA is
made impossible. The same applies for MDA from which one may change neither directly nor indirectly to AUTO, provided
the Reset state is present.
The table shows the possible operating mode changes depending on the current operating mode and the channel state
("Channel in reset" or "Channel interrupted").

Possible mode changes are shown by an "X".
Error on operating mode changeover
A corresponding error message is output if a mode change request is rejected by the system. This error message can be
cleared without changing the channel status.
Mode change disable
Changeover between operating modes can be inhibited by means of IS "Mode group changeover disable"
(DB3000.DBX000.4). This suppresses the mode change request.
