Overview
Introduction
For SINAUT ST7, there is the SINAUT TD7 software package for process data transmission
between SINAUT subscribers over WAN, MPI bus and Ethernet. There are two variants of
the software package:
● The SINAUT TD7 for the CPU software package, known as TD7onCPU, is a software
package that has parameters 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.
● The SINAUT TD7 for the TIM software package, known as TD7onTIM, is a software
package that is configured on Ethernet TIMs and runs on these TIMs. It can be used as
an alternative to the TD7onCPU software package if an Ethernet TIM is configured in a
SINAUT station.
TD7onTIM is described in the section Configuration software for SINAUT ST7.
This chapter only describes the TD7onCPU software package.
The TD7 software package for the CPU contains blocks specifically for CPU modules. The
package was designed so that it can run both on an S7-400 and on and S7-300 CPU.
Exceptions to this will be pointed out explicitly.
With the aid of the SINAUT TD7 software, the user creates a program for the CPUs. This
program 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/control center has
started up, data is updated automatically.
Apart from process data transmission over WANs, the package is also suitable for local
communication between CPUs if these are connected together over MPI. Even here, the
local connections and CPUs are constantly monitored and data is updated automatically
following startup or after a problem has been eliminated.
Note
Data communication from CPU to CPU 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 content of the SINAUT TD7 software package
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
