1 Page 1 of 3 IBH Link S5++ The IBH Link S5++ is a communication adaptor that permits to establish ethernet connections to the standard PU port of a SIMATIC S5 PLC. Under normal circumstances the IBH Link S5++ obtains its power supply from the PU port of the CPU. If the PLC does not deliver power, the 24V can be supplied externally. The outer pin is 0V (GND), the inner pin is +24V. Besides PU functions with S5 for Windows also S7-HMI devices can read and write variables from the PLC. The following protocols are supported: PU communication with S5 for Windows IBHsoftec OPC Server for Visualization (HMI) PC Fetch / Write via TCP/IP S7-TCP/IP (RFC1006) Variable services for current S7-HMI Panels Upon delivery the IBH Link S5++ has the IP address If no DHCP server is available in the network, it falls back to this address. In order to find and configure the device, the IP address of the configuration PC may be changed to match the IBH Link S5++ via the Control Panel. To set the address, the program "S5IBHLink.exe" needs to be started. The following screen appears: OK - Exits the configuration Settings - Opens the configuration dialog for the selected link Search again - Searches for devices in the local network again? - Opens the help mk:@msitstore:c:\windows\system32\ibhnet.chm::/english/ibhlink_s5_pp.htm

2 Page 2 of 3 The IP address can be set either static or can be obtained from a DHCP server. If set to DHCP, a DHCP server should be available in the network. To use PU functions with S5 for Windows, the desired port number can be set. By default this is For Visualiziation (HMI) systems, that support the protocol Fetch/Write S5 via TCP/IP, the desired port can be set as well. The Fetch/Write requests will be decoded and be forwarded to the AS511 port of the PLC. For Visualization (HMI) systems, that support the S7 protocol RFC1006 via TCP/IP, the port ist fixed to 102. The MPI telegrams sent via RFC1006 will be decoded and be forwarded to the AS511 port of the PLC. Save permanently - Saves the settings in the IBH Link S5++ flash memory. Following dialog appears. After successful restart the device is ready. Further configuration is not required. Parallel services: All services can be used in parallel. But it should be considered, that the AS511 port of the S5 only works with 9600 baud and the communication load will be shared by all services. This fact may require higher timeout settings for the connected devices. mk:@msitstore:c:\windows\system32\ibhnet.chm::/english/ibhlink_s5_pp.htm

3 Page 3 of 3 Operation with S7 HMI devices: For the operation with S7 HMI devices the following settings need to be made: IP address of the PLC = IP address of the IBH Link S5++ Rack number of the PLC = 0 Slot number of the PLC = 2 MPI address of the PLC = 2 The checkbox "Cyclic operation" (WinCC Flexible / ProTool) must be OFF. For WinCC "Use cyclic read service of PLC" must be OFF. In the message settings of the project the checkboxes for "S7-Diagnostic messages" (Text and Number) must be OFF. Also the "SIMOTION diagnostic messages" must be OFF, since these services are not available on a S5. Some thoughts about the S7 HMI projects: Since a S7 communication is by nature much faster than a S5 communication may ever be, this fact should be considered. When creating a project for a S7 HMI device that talks to a S5, some project guidelines can be found below. Timers respectively Counters may change during a read/write cycle. For this reason they are deactivated. If they are addressed by the HMI device, a "PLC address Error" will be returned. If Timers and Counters are required, they must be managed via a data block. Values can be read and written from the input and output process image, as well as flags and the content of datablocks. It is recommended to optimize the variable areas already during creation the project, in order to permit the fastest possible data exchange with the S5 PLC. If there are many single variables from different areas of the PLC in one screen of the project, many single requests need to be sent to the S5, in this case the integrated optimization cannot do it's work. This takes time. For this reason the refresh rate of a variable should be reduced to permit the PLC to answer the requests within the time frame configured in the project. If optimization can fully work, refresh rates from ms are realistic. If there is no optimization possible, reading may take a few seconds. An average refresh rate of a second should be a good point to start. However, in some cases it will make sense to combine all variables within one screen to an array. With only one read/write cycle blocks of data can be exchanged optimized with the S5. This saves time and better refresh rates can be gained. DB addresses are word oriented in S5. The DW0 in a S5 is equivalent to the DBW0 of a S7. The DW5 of a S5 is equivalent to the DBW10 of a S7. All other addresses within DBs follow this logic. S5 S7 DL 0 DBB 0 DR 0 DBB 1 DL 1 DBB 2 DR 1 DBB 3 DL 2 DBB 4 DR 2 DBB 5 or DW 0 DBW 0 DW 1 DBW 2 DW 2 DBW mk:@msitstore:c:\windows\system32\ibhnet.chm::/english/ibhlink_s5_pp.htm

IBH Link S5++ assignment The IBH Link S5++ assignment maps a virtual COM Port to the IBH Link S Selected IBH Link: Select the station of the IBH Link S5 ++ to be used with the virtual COM Port. The station must have been created before. See chapter "IBH Link S5 ++". - Active: Activates the virtual COM Port. - COM: Shows the currently selected virtual COM Port. - Status: Current state of the virtual COM Port. - Installation state: Shows whether a virtual COM Port is installed. - Install: Installs a virtual COM Port to a COM number of your choice. This must be done to provide a virtual COM Port. - Change interface: Selection of the COM port number. - Uninstall: Uninstalls the virtual COM Port to make it free for other applications. - Search/Configure IBH Links: Opens the dialog "IBH Link S5 ++ in the local network" to configure the IBH Link S5 ++. See chapter "IBH Link S5 ++". - Minimize: Closes the dialog but lets the virtual COM Port activated. - Exit: Close the dialog and shut down the virtual COM Port. Virtual S5 COM Port for STEP 5 mk:@msitstore:c:\windows\system32\ibhnet.chm::/english/ibh_link_s5ppvcome.htm

5 Page 2 of 2 This application maps the virtual COM Port to one of the possible COM Ports in STEP 5, i.e. COM1 to COM4. This must be done only once, even if the PC is restarted. The previously installed virtual COM Port appears as "\Device\IBHVCom" NOTE In case of problems please do not assign a virtual COM Port for STEP 5 to a physical COM Port of the PCs with the same number. Please assign only to free COM Port numbers. e.g.: STEP 5 COM 1 <-> PC COM 2 STEP 5 COM 1 <-> PC COM 3 STEP 5 COM 1 <-> PC COM 4 STEP 5 COM 2 <-> PC COM 1 STEP 5 COM 2 <-> PC COM 3 STEP 5 COM 2 <-> PC COM 4 etc... mk:@msitstore:c:\windows\system32\ibhnet.chm::/english/ibh_link_s5ppvcome.htm
