Installation under Windows 98/ME/NT operating systems is possible but is not supported by the technical support team of Helmholz GmbH & Co.KG. Please pay attention to the require- ments of the Simatic package used. A functioning network link using TCP/IP must have been set up on the PCs that are used. -
Page 18: Adding The Interface To The Pg/Pc Interface
When installing the program on Windows 7 operating systems, make sure to not only log in with the Administrator account, but to also run the program setup file using the “Run as administra- tor” option! For more detailed information, please refer to the relevant NET- Link Quick Start Guide. - Page 19 This opens the ‘Install/uninstall interface’ dialog box. After you have selected the entry ‘NETLink-S7-NET PRO family’ from the left-hand list, click the ‘Install-->’ button.

This auto-baud function is only supported when the 'Cyclical dis- tribution of the bus parameters' is activated in the involved automa- tion system. This function is not available in S7-200 systems in general. -
Page 23: Profibus Configuration
Some older Siemens CPUs do not support the auto baud function on the MPI. PPI systems do not usually support this function ei- ther. In such cases, the network-related parameters should be adapted manually.

- Page 25 In this way you avoid the laborious steps involved in manual configuration, and most importantly ensure that profibus ® networks work with many participants of the NETLink with the correct profibus parameters. Under PROFIBUS, please note that the auto baud function works best if the ‘Cyclic distribution of the bus parameters’...
-
Page 26: Ppi Configuration
5.1.3 PPI configuration Generally, the same thing applies under PPI as for the MPI con- figuration. However, it should be noted that passive participants never transmit the Profibus parameters, and that it is thus not possible to "automatically" determine the bus parameters. Normally the baud rate cannot be detected auto- matically at PPI systems. -

The ensuing reset would interrupt the NETLink ® link The password query must be answered correctly and confirmed with OK. • All NETLink ® Gateways be protected against unauthorized reparameterization via a password. If an attempt is made to save a parameter set with an incorrect password, the following messages is displayed: The default password is ‘admin.’... - Page 28 Internet tele servicing to networks outside of the LAN should al- ways be realized through secured and encoded procedures, such as VPN! To this purpose, the Helmholz GmbH offers appropriate router hardware. ‘OK’ stores this station, which can now be used.

Page 29: Setting Tcp Parameters
® If you do not want the name that is stored in the NETLink to be the same as the station name, you can overwrite the station name (e.g. replacing the name ‘Helmholz_test’ with the name ‘Workshop’ in the example below). This completes parameterization of the driver. -

Page 50: Rfc Multicomputing With Tsap
9.2.1 RFC Multicomputing with TSAP This function makes it possible to communicate with more than one CPU on a rack ( multicomputing) in S7-400 systems with- out any need for the additional CPUs to be connected to the same PROFIBUS cable. For this to be possible, direct communications take place with on- ly one single configured station (CPU address 49 in this example). - Page 51 For this to be possible, direct communications only take place with one single configured station (CP address). This station then forwards data packets to the desired rack/slot. If you use this mode, the following settings must be configured on the web interface configuration page: •...

Q: The setting dialog boxes are not appearing in the Simatic Man- ager: A: Please note that after initial installation the NETLink-S7-NET driver must be added to the PG/PC interfaces interfaces (except with Windows 7 operating systems).
- Page 54 A: The default settings of the system parameters in register SI- MATIC S7 for Cycle Formation, Sign-of-Life Monitoring and CPU-Stop Monitoring must be deactivated. Q: How can I specify the target station(s) for RFC 1006 communi- cations in WinCC by using the Rack/Slot fields? A: Since the RFC protocol does not have a default entry for speci- fying the PROFIBUS/MPI address of a target station (PLC), you will have to use the 2 byte-long TSAP field.

A microwave plug or a microwave socket that is used for HF and microwave techniques as well as in WLAN due to its robustness.
- Page 65 Virtual Private Network. Logical links, called tunnels, are established iva existing unsecured networks. The end points of these links (“tunnel ends”) and the devices behind them can be thought of as a separate, logical network. A very high level of security against tapping and tampering can be achieved if data transmission via tunnels is encrypted and the stations in this logical network first authenticate each other.
