The SINAUT ST7 standard software package
The SINAUT ST7 standard software package comes on a CD-ROM and is made up of two
parts:
1.
The SINAUT TD7 library that contains blocks for the S7 CPU
2.
The SINAUT ST7 configuration and diagnostics software for installation on the
programming device
The CD-ROM also contains the SINAUT ST7 manual in electronic form (German/English).
The software package is a working package that can be used for any number of SINAUT
projects without licensing.
1.9.1
SINAUT TD7 Library, blocks for the CPU
The SINAUT TD7 library is a software package with blocks for the CPU. The package was
designed so that it can run both on an S7-400 and on and S7-300 CPU. There are only a few
blocks intended specifically for the S7-300 or S7-400 CPUs.
The SINAUT TD7 software in the stations allows change-driven transmission of process data
between the individual CPUs and the control center, for example ST7cc. Failure of
connections, CPUs, or the control center are displayed. Once a problem has been corrected
or the CPUs or control center has started up, data is updated automatically. When
necessary, data messages can be given a time stamp.
Note
Data communication from the CPU to other CPUs or to ST7cc/ ST7sc over a WAN
connection can only be implemented with the SINAUT TD7 software. This is not possible
with the S7 communication SFBs/SFCs for configured and unconfigured connections. These
are suitable only for local communication without a gateway.
The essential components are the package are as follows:
●
Basic and auxiliary blocks
Most of these blocks are always required on the CPU. A few are purely optional. The
basic blocks handle central tasks such as startup, monitoring of connections and
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 or provide information as a
result of searches.
●
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 and output
received process data.
To operate correctly, the TD7 package requires some data blocks that are generated by the
SINAUT ST7 configuration tool. These are as follows:
