Downgrade
(device update
tool)
B SIMOTION D4x5‑2 control units and projects can be upgraded
using upgrade data created at an earlier point in time. This
upgrade
data are generated with the device update tool (Menu:
"Project>Start device update tool" in SIMOTION SCOUT).
If the upgrade process fails to bring about the desired result,
the upgrade can be rejected by means of the switch position.
This will roll the system back to the previous configuration.
Backup of
diagnostic data
and non-volatile
SIMOTION data
D The diagnostic data and non-volatile SIMOTION data can be
backed up in STOP, STOPU, and RUN state. The advantage
of backing up in RUN state is the availability of enhanced
diagnostic information (via HTML pages) and TO alarm
information.
Note
Alternatively,
diagnostic data and non-volatile SIMOTION data can also be backed up via the
DIAG button, see Section DIAG button (Page 48).
