Page 9: Installation And Mounting
• For the NETLink PRO ETH, a minimum clearance of 60 mm must be left above and below and 10 mm at the sides. Installing the module A wall/DIN rail bracket is available as an accessory for mounting on flat surfaces or on DIN rails. -
Page 10: System Overview
The RFC1006 interface also enables you to use third-party software that supports this protocol for S7-300 and S7-400 systems. In both cases the NETLink PRO ETH is connected to the PC via a switch or hub. If the NETLink PRO is connected directly to a PC, a crossover adapter must be interposed between the PC and the NETLink PRO ETH (for accessories, see section 3.5). -
Page 11: Connections
The terminating resistor must be connected (ON) if the NETLink PRO ETH is at the beginning or end of a bus segment. If this is not the case, the switch position must be OFF. The 1.2 m connecting cable is an ‘active cable’. This means there is no spur line, which avoids interferences with high baud rates. - Page 12 Activity on the network BLINK BLINK Activity on the network The three LEDs (two two-color LEDs) on the top of the NETLink PRO ETH indicate the operating status of the device itself: LED status for operating Power LED Active LED...

Page 14: Installation Of The Driver Software
Installation of the driver software With installation of the NETLink PRO driver for the NETLink PRO ETH, it is easy to access controllers with a PPI, MPI or PROFIBUS interface from the PC via TCP/IP. Introduction The NETLink PRO driver is inserted in the PG/PC interface of an existing Simatic application and can then be used from most Simatic engineering tools (STEP7, ProTool, WinCC, etc.). - Page 15 If you answer ‘Yes’ to this query, the NETLink PRO ETH is immediately set as the current access path. If you respond ‘No’, the previous access path remains set and the NETLink PRO ETH is put in the selection list where you can select it later.

Page 16: Selecting The Required Interface Parameterization
Now you have answered the query, ‘NETLink PRO ETH’ will also appear in the right-hand list with the interfaces already installed. The access path in the ‘Set PG/PC Interface’ dialog box is set when this window is closed. 4.3.2 Selecting the required interface parameterization The selection list for the interface parameter sets now contains an additional three items for the NETLink PRO ETH. -
Page 17: Configuration Via The Netlink Pro Driver
Configuration via the NETLink PRO driver Once a NETLink PRO ETH has been selected in the ‘Set PG/PC Interface’ window, it is possible to specify this access path more precisely with the ‘Properties…’ button.

Page 24: Bus Settings
The MPI configuration contains station and network-related settings. The most important setting concerning bus configuration is assignment of the station address. This refers to the address the NETLink PRO ETH will have on the bus when it goes online. The station address can have any value from ‘0’ and ‘126’ if the selected address is lower than or equal to the highest station address (HSA). - Page 25 To simplify configuration, the ‘Automatic transmission rate detection’ function can be deselected in the station-related settings. This causes the NETLink PRO ETH with the preset station address to ascertain the baudrate and associated bus parameters itself. If this function is required, no manual setting of the network-related parameters is possible.
- Page 26 Unlike the MPI bus profile, the bus parameters for PROFIBUS are not constant and change with the type and number of PROFIBUS stations used. The PROFIBUS parameters should always be set equal to the parameters of the currently used programmable controller (see STEP7 project). NETLink PRO ETH...

Page 40: Using The Rfc1006 Option (S7-Tcp/Ip)
Because many visualization system manufacturers have implemented this protocol to ensure a connection to Simatic controllers via TCP-CPs from Siemens (e.g. CP343 or CP443), NETLink PRO ETH with RFC1006 is a lower-cost alternative to communication with these visualization systems. Please notice the RFC1006 functionality is not accessible with S7-200 The usage of RFC1006 at systems connected to the NETLink PRO ETH. -
Page 41: Autobaud On/Off
If RFC1006 functionality is deactivated, the following parameters will have no influence on the functioning of the NETLink PRO ETH. However, if an attempt is made to communicate with the NETLink PRO ETH via RFC1006, the service will be denied. -

CPU => Routing). Because NETLink PRO ETH is a point-to-multipoint communication adapter (‘PC to NETLink PRO ETH’ on the one hand and ‘NETLink PRO ETH to many bus stations’ on the other hand), it was necessary to implement different addressing methods to permit all communication variations. - Page 43 These two addressing methods, which are mutually exclusive, permit most types of communication that are also possible via the NETLink-S7-NET. 8.1.4.1 Addressed mode If different CPUs are to be accessed on the same MPI/PROFIBUS via RFC1006, addressed mode is suitable.

To parameterize a RFC1006 link in WinCC, a new TCP/IP link must first be created in the ‘SIMATIC S7 PROTOCOL SUITE’. - Page 45 NETLink PRO ETH and the rack/slot combination of the destination have to be entered. In this case, the NETLink PRO ETH has the IP address 192.168.4.49. The destination CPU with which we want to communicate has the PROFIBUS address 49. Because addressed mode is to be used, we can read off the correct value for the rack and slot from the table in Section 10.3.1.

To parameterize a RFC1006 link in WinCC, a new TCP/IP link must first be created in the ‘SIMATIC S7 PROTOCOL SUITE’. Here, this connection is called ‘NETLink_PRO’. - Page 48 NETLink PRO ETH and the rack/slot combination of the destination have to be entered. In this case, the NETLink PRO ETH has the IP address 192.168.4.49. The destination CPU with which we want to communicate is in Rack 0 on Slot.

Page 50: Troubleshooting
Troubleshooting Q: I connected the NETLink PRO ETH directly to my PC/notebook but it doesn't work. A: A direct connection between two NIC (network interface card) interfaces is not possible. You need a cross-over adaptor (Order no: NETLINK- CROSS) or a switch/hub for connecting two Ethernet terminal devices together. - Page 51 A: The NETLink PRO driver communicates with the NETLink PRO ETH via TCP port 7777. UDP ports 25342 and 25343 are also used to search for the NETLink PRO ETH devices. Please release at least port 7777 so that the basic functionality of the driver is available.
- Page 52 Q: I am getting requested for a password if I try to configure the NETLink via configuration tool or web interface. But I never configured one. A: Since version 1.40 the NETLink PRO firmware always has a password. If no password is given by the user, the firmware sets the passwort to ‘admin’.
- Page 53 A: Make sure that the bus is correctly terminated. Even if the NETLink PRO ETH is the only device on the bus apart from the CPU, the terminating resistor must be connected. Otherwise problems may occur, especially at high baudrates.
- Page 54 2 for my existing CPU in the Web interface in ‘Fix destination address for R/S mode’. Although NETLink PRO ETH online is active (active LED lights up), my visualization system tells me that no link can be established.
