2.4.3
Replacement of the System TC and Backup TC
If the
System TC
detects a conflict compared with the
backup TC
then this situation must first be resolved
before updating any other TC in the system. If the
System TC
detects that a
backup TC
with different
software version exists in the system then there is no possibility to automatically detect which TC that has
been replaced.
The solution to this is to show the above described text on both the
System TC
and the
backup TC
and let
an operator decide which TC to update.
Any other TC in the system will show the normal version conflict message as long as there is a conflict
between the
System TC
and the
backup TC
.
Note:
It is not possible to download new software to the
backup TC
from a
System TC
that has no valid
setup.
2.4.4
Replacement of TC3
– TCn
If the
System TC
and
backup TC
contains the same software version and has a valid setup the
System
TC
continues to check for any software version conflict among TC3
– TCN. If one or several Spindle TCs
are found with a different software version the above described dialog appears on all the replaced TC. The
Spindle TC then starts to download the new software from the
System TC
by using functions provided by
the
System TC
.
Note:
Since the
System TC
only initiates the download of new software any number of Spindle TCs could
download new software simultaneous without any interference from the
System TC
.
2.4.5
Updating a system with new software
As described in the previous chapter it would be possible to update a whole system with new software by
only download it to the
System TC
and then let the Automatic Download function update the rest of the
TCs in the system.
Note
: For this to be possible the
System TC
must have a valid setup loaded.
2.4.6
Troubleshooting
If by any reason the download software process to any TC is interrupted by loss of power or network error
etc. then a TTPM must be used to update these TC since the Automatic Download function would not be a
part of the boot loader.
