availability of connection partners, general requests, time management, handling
communication etc. The auxiliary blocks enter messages in the send buffer or fetch them
from the receive buffer, handle send and receive jobs for specific connections, provide
information as a result of searches, etc.
● Data point typicals
These blocks are included in the CPU program depending on the type and amount of
data to be transferred. They put messages together when data changes or when
requested and output received process data.
Blocks required with the SINAUT ST7 configuration tool
To operate correctly, the TD7 package requires several data blocks per CPU. These DBs
are generated automatically by the SINAUT ST7 configuration tool when the SINAUT
connections are configured and they are stored on the relevant CPU. These are as follows:
● Central records DB
This contains all the centrally required data including the records of all communication
partners and the connections to be managed.
● Communication DBs
A separate communication DB is created for each connection. This DB contains a send
and receive buffer and all the data required for controlling and monitoring the connection.
Along with the data blocks mentioned above, the SINAUT ST7 configuration tool also stores
the basic and auxiliary blocks necessary for a functioning program in the CPU program
directory. Users only need to copy the required data point typicals from the SINAUT TD7
library to the CPU program directory and they can then create the SINAUT user program.
Note
The blocks stored in the CPU program director by the SINAUT ST7 configuration tool exist
once as individual blocks in the 'Blocks' directory and also in the 'Sources' directory as an
STL source file with the name 'TD7_UserSource'.
