SINAUT ST7 protocol
This protocol is used in the SINAUT ST7 system for data transmission via classic WAN
networks and IP-based networks. It is a further development of the SINAUT ST1 protocol.
SINAUT TD7 Library
The SINAUT TD7 library is a software package with blocks for the CPU. The package can be
run both on an S7-300 or an S7-400 CPU (except the S7-400H CPUs). 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 have 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:
● TD7onCPU
Library with SINAUT blocks that are linked into the program of the CPU and are executed
there. The library can be used with all TIM types and is suitable for all S7-300 and S7-400
CPUs (except the S7-400H CPUs).
● TD7onTIM
SINAUT TD7onTIM is the TD7 variant that runs on the TIM. It is available for the
→ Ethernet TIMs and can only be used in an S7-300 station. TD7onTIM and TD7onCPU
can only be used as alternatives in a station. Simultaneous use is not possible.

SMS
(Short Message Service)
The short message service in the GSM standard is used to transfer short text messages to
mobile wireless users.
When the short messages are transferred, they are first transferred to the SMS center
(SMSC) using a store-and-forward technique. They are buffered there and then forwarded to
the recipient. The sender can query the status of the message in the SMS center or can
request acknowledgment of delivery.
Spontaneous message
In SINAUT networks, messages are always transmitted spontaneously; in other words,
messages are created and transmitted only when changes to process values occur or event-
driven. These messages are known as spontaneous messages.
