SINAUT message
An ST7 message contains the data of an ST7 object for transmission. Depending on the
object type, a message can contain either all data of an ST7 object or only a contiguous
subarea of the object data.
SINAUT object
A SINAUT object contains the data of one or more process variables such as analog values,
commands, calculated values, status information on motors, sliders etc. An ST7 object has
type-specific processing functions and change checks assigned to it to minimize the
communication traffic in the WAN. Type-specific processing functions include, for example,
threshold checks or mean value calculation with the object type for analog values. The
change check is designed so that a message is generated only when the object data has
changed compared with the last time its value was transferred or when the type-specific
processing enables generation of a message because the object data is "worth" transferring.
SINAUT TD7 Library
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 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.
There are two variants of the SINAUT TD7 software package:

SINAUT TD7onCPU
assigned on the CPU and that runs on the CPU. It is used in all SINAUT stations in which
TIM modules of the type TIM 3 or TIM 4 are configured.
SINAUT TD7onTIM
runs on TD7onTIM-compliant TIM modules, for example the TIM 3V-IE. This can be used
as an alternative to the TD7onCPU software package when a suitable TIM is configured
in a SINAUT station.
