4.2.7 Downloading newly compiled SDBs to TIM modules
If new SDBs have been compiled for an existing SINAUT ST7 system, they must then be
downloaded to the relevant TIM modules of the system.
Without PG routing, SDBs are downloaded locally to each TIM of the MPI bus. A further
option for downloading SDBs from the master station to the remote TIM modules is
described in the section
Central SDB downloading with PG routing .
Note
The new system data blocks are downloaded to a TIM module using the SINAUT
Diagnostics and Service tool function
Download SDBs . You will find more detailed
information there.
To activate newly downloaded SDBs on a TIM module, the TIM must be restarted. The
consequences of restarting a TIM module are, however, as follows:
● The connection from the PG to the TIM is terminated.
● The connections from the TIM to other SINAUT partners (SINAUT connections) are
terminated. This leads to error messages on the partners of the TIM module.
● In the case of a node TIM, the connections to the downstream stations are also reported
as being disrupted.
● With a node TIM, any data messages stored on the TIM are lost during the restart. This is
particularly relevant in station TIMs in the dial-up network.
When downloading SDBs to TIM modules, you should therefore note the following points:
● Before you transfer the SDBs, you should give the TIM the opportunity of transferring any
messages stored on it.
● After restarting the TIM, the SINAUT connections are automatically re-established. If the
connection from the PG to the TIM is required, however, it must be activated from the PG
of the user.
4.2.8 Central SDB download using PG routing
SDBs can be downloaded as previously for each TIM locally over the MPI bus. It is,
however, conceivable to perform this from the master station; in other words, to use the
options of PG routing although the system was not activated for this function. This method
can be considered if you already know that the TIM modules in the stations are suitable or
prepared for PG routing in terms of the operating system and TIM firmware.
In the following sample configuration, the central downloading and activation of the SDBs is
performed in four consecutive steps:
