2 1.0 Introduction With the IBHNet driver for the IBHLink and the S7-SoftPLC, controllers can be easily programmed and maintained via ethernet using the TCP/IP protocol. Besides programming and variable access, also monitoring the block status of the controller is possible via the IBHNet driver. The IBHNet driver can be used in conjunction with S7 for Windows, with the IBH OPC Server and Simatic STEP 7. Also, the IBHNet driver enables you to gain a direct variable access via standard programming languages like Visual Basic or Delphi. The following PLC controllers can be accessed with the IBHNet driver: - An IBHsoftec S7-SoftPLC, operated on the same PLC. - An IBHsoftec S7-SoftPLC, connected via a local area network, via an Intranet or via the Internet. - Any Simatic S7-300 or S7-400 PLCs, connected via a local area network, via an Intranet or via the Internet. To establish a connection of a Simatic S7-300 or S7-400 PLC with the ethernet network, the communication adaptor IBHLink is required. 1.1 System requirements To install the IBHNet driver on your PC, the following minimum requirements need to be fulfilled by your system: The PC needs to have a 32-Bit Windows Operating System installed. S7 for Windows supports the IBHNet driver starting with version 4.14, the IBH OPC Server starting with version If you are using Simatic STEP 7, it can be used starting with version 5.1. Following operating systems are supported: Windows95 (with Internet Explorer 5.5 and Windows Sockets 2 Update installed), Windows98 (with Internet Explorer 5.5 installed), Windows ME (with Internet Explorer 5.5 installed), Windows NT4 (with Service Pack 6 and Internet Explorer 5.5 installed), as well as Windows 2000 (with Internet Explorer 5.5 installed) and Windows XP. Please also seek for the minimum requirements of your STEP 7 package. If the IBHNet driver is to be used in combination with the communication adaptor IBHLink, please ensure to connect the IBHLink whenever possible directly to the MPI or the Profibus connector of the Simatic S7-300 or S7-400 PLC. If this in some cases may not be possible, it can be necessary to externally supply the IBHLink communication adaptor with a 24V DC supply voltage. IBHsoftec offers special adaptors, if required. The IBHNet network support is integrated in the S7-SoftPLC starting with version If you are using an older version of the SoftPLC, you need to update the SoftPLC, to gain the networking capabilities of the S7-SoftPLC. The used PCs need to have a working network connection via TCP/IP installed. The network names and the IP-Addresses of the used PCs need to be known by the user. Please contact your administrator, if you do not know these numbers. As network hardware any network adaptor that supports Windows and TCP/IP can be used. In a local area network 100 MBit network adaptors and switches should be preferred, in order to gain the best performance. Of course 10 MBit network adaptors can also be used, but they will slow down operation, especially when viewing a block status.

3 1.2 Installation Please make sure to be logged in as administrator, if you are planning to install the IBHNet driver on one of the 32-Bit Windows operating systems Windows NT4, Windows 2000 and Windows XP, since the setup program needs to make entries into the Windows registry during the installation. To install the software, please run the program Setup.exe from the CD and follow the instructions on the screen. Please make sure, that the name of the installation folder does not contain any spaces or other special characters, since the STEP 7 software cannot find the driver in that case. Best is, to keep the old MS-DOS 8.3 convention (8 Characters for the filename, 3 characters as file extension). If STEP 7 is installed on Windows NT4, Windows 2000 and Windows XP, it is required to install the Siemens communication driver for the PC-Adapter (MPI) prior to installing the IBHNet network driver. Upon completion of the installation, please restart your PC. Only a complete restart enables Windows to activate the altered settings. After the installation, the new entry IBHNet can be found in Start-Programs. Run the program IBHNet and IBHLink Settings from the IBHNet menu. With this program, the IP addresses of the connected IBHLinks can be set. The configuration screens of the IBHNet driver can also be accessed from the menu Set PG/PC interface within STEP Local operation with a S7-SoftPLC If the programming software and the IBHsoftec SoftPLC are used on the same PC, the IBHNet driver needs to be installed only on this PC. Enter the IP Address of the local PC in the driver settings, to obtain access to the SoftPLC. 2.1 Operation in a local area network If the programming software and the IBHsoftec SoftPLC are used on different PCs in the same local area network, the IBHNet driver needs to be installed on the PC with the programming software, as well as on the PC with the IBHsoftec SoftPLC. If the IBHLink communication adaptor is used, it is sufficient to install the driver on the PC with the programming software. In order to set up a connection to the PLC in the driver settings, the IP address of the PC with the SoftPLC, respectively the IP address of the connected IBHLink needs to be known by the user.

4 2.2 Operation via the Internet If the programming software and the IBHsoftec SoftPLC are used on different PCs in the same local area network, the IBHNet driver needs to be installed on the PC with the programming software, as well as on the PC with the IBHsoftec SoftPLC. If the IBHLink communication adaptor is used, it is sufficient to install the driver on the PC with the programming software. In order to set up a connection to the PLC in the driver settings, the IP address of the PC with the SoftPLC, respectively the IP address of the connected IBHLink needs to be known by the user. To be sure that the network connection is alive, please make sure that the remote PLC can be reached via the ethernet network. The easiest way do this, is to send a PING <IP-Address> from the DOS-Box. Currently the SoftPLC uses the TCP ports 710, 711 and 712. If your PLC sits behind a firewall, you need to open the appropriate ports for a communication in your firewall-software. Consult your administrator or the documentation of your firewall on how to permit access via certain ports. For future revisions a 16-channel communication is planned. It may be a good idea to already configure the following 32 Ports starting at port 710 (total of 33 ports) in the firewall software. The IBHLink uses the port 1099.

5 3.0 Configuration of connected PLCs For an initial setup of the IP address, the IBH Link must be in the same network segment as the PC with the IBHNet driver software. From Start Programs IBHNet run the program IBHNet and IBHLink Settings. A window as shown below will be displayed: Since no PLC names are defined yet, an empty list will be displayed. Prior to defining a symbolic name for the PLC, an IP address needs to be set for the connected IBHLink. To setup or change a PLC, it is necessary to have at least default user rights. 3.1 IBHLink S7 To do so, please click IBHLink settings.

6 In the list all IBHLink S7 that are connected to the same network segment will show up. If no IP address has been defined yet, it will show up with the address If no IBHLink S7 is shown in the list, it is either not in the same network segment (i.e. cannot be reached with a broadcast) or it is not in configuration mode. In this case please click Search again. A message box as shown below will be displayed: Follow the instructions on the screen and disconnect the IBHLink S7. Re-connect it after 2-3 seconds. 6 seconds after re-connecting it, click OK. The list will be refreshed and the IBHLink S7 will be displayed in the list. In the first 3 minutes after power on the IBHLink S7, the IP address can be set, if the IBHLink S7 is in the same network segment. Select the IBHLink S7 you want to configure from the list and click Settings. If the selected IBHLink S7 has not got an IP address the following window will appear. This dialog also shows up, if IP address and network segment, between PC and IBHLink S7 are not matching.

7 The IP address set in this dialog is just temporary and is exclusively to configure the IBHLink S7 for the first time. If the IP address could set up successfully, the real configuration dialog will be opened. If you will not confirm the following dialog with Save permanently, the IP address will be set, after the next restart of the IBHLink S7 back on the old value ( ). In the following dialog, set the IP address, the subnet mask and if available a gateway address. If no gateway is available in the network, leave these fields empty. Select the data transfer rate of your MPI or Profibus network. If MPI is selected normally the setting is 187,5 kbaud. If the IBHLink is to be used on a Profibus network, it needs to be set to the baudrate, which is configured on the CPU. For a CPU315 2DP the standard setting is 1,5 Mbit/s. Exactly the same data transfer rate as on the CPU needs to be chosen. If the CPU has some weird timing parameters, an advanced profibus parameter screen can be opened to set these parameters. The setting of these parameters can be found in the hardware configuration of the CPU. Since the IBHLink is also a device, which is connected to the MPI/Profibus network, it also has to have an unique MPI/Profibus address. The factory setting is address 0. The Siemens factory setting for a programming device is 0, an Operator panel has the address 1 and a CPU the address 2. Take care to not set a conflicting address for the IBHLink. Also the maximum address in the network, as configured on the CPU and the busprofile MPI/Profibus needs to be selected.

8 After all settings are made, click Save permanently to save the settings in the IBHLinks flash memory. Follow the instructions in the appearing message box to save the settings. Then the configuration of the IP address and the bus is completed. The IBHLink S7 can now be used. The firmware release is also shown in the in the dialog box. By clicking Firmware download the IBHLink S7 can be updated to the newest firmware release. In the installation folder (normally C:\winnt\system32 or C:\windows\system) the file Nlmpi.e11 can be found. This file holds the firmware of the IBHLink communication adaptor. This file needs to be replaced with a file that holds a more recent firmware, if the firmware of the adaptor is to be replaced. If Firmware download is selected, you will be asked to confirm this operation. Clicking Yes will start the update. 3.2 IBHLink S5 For this click the button S5 IBHLink.

9 The list is empty, after a click on the button Suche im lokalem Netz, which means Search on LAN, all IBHLink S5 in the same network segment as your PC shows up. If no IP address is setup, on the list the address appears. If no IBHLink S5 shows up, it is not in the same network segment or not in configuring mode. In this case click on Suche bestimmte Adresse, which means Search given address. The following dialog shows up: Enter the IP address of the IBHLink S5 you want to configure and press suchen, which means search. Select the IBHLink S5 you want to configure and press the button Einstellungen, which means Setup. In the following dialog enter the PLC name (Gerätename), the S5-PG-Port, the S5- Server-Port, the network segment (Subnet-Maske) in which the IBHLink S5 is used and the address of a possibly existing gateway. If there is no gateway available, leave these fields empty. After you entered all your settings, click on OK. The IBHLink S5 now has the new IP address and can be, if your PC is in the same network segment, found as described before in the S5LANMangager. The Firmware of the connected adapter is shown in the dialog field too. After pressing the button Firmware laden, which means Load firmware, the IBHLink S5 can be setup to the updated state. It will open an open data dialog, in it you can search for the new firmware version on your PC. After quitting the dialog with open the firmware update starts.

10 4.0 Defining access names to identify the PLCs By defining a symbolic name for the PLC, it is not necessary to always remember the IP addresses of the CPU. In the next step, we will assign the IBHLinks IP address to a symbolic name for the PLC. From Start Programs IBHNet run the program IBHNet and IBHLink Settings. The screen as shown below will be displayed: In the list, existing stations can be selected. If Change Station is clicked, changes can be applied to definitions of already existing stations. The buttons S7 IBHLink and S5 IBHLink will lead back to the settings of the IBHLink S7/S5, as already discussed in section 3. We assume, that no station has yet been defined. Click New Station to define a new symbolic name. The dialog below will appear:

11 Enter the IP address of the IBHLink S7, IBHLink S5 or the SoftPLC. A selection needs to be made, which type of device it is. Enter a time for a connection timeout. For Step7 a time about 2000 ms has approved, for ProTool CS 4000 ms, for ProTool RT or OPC Servers use 1000 ms. For an S7-300/400 or OP it needs to be chosen, whether the IBHLink S7 is connected to the MPI or Profibus interface. For the S7-200 the PPI interface needs to be selected. Additionally you can choose if you want to test your network connectivity with a ping before you connect. This should be done if you can not be sure about the reliability of your cable connection. If firewalls and/or routers are used, it might be necessary to disable that option. With ProTool RT or OPC Servers Test network connectivity should always be activated. Type a unique name for the PLC and click Apply. The dialog will close upon clicking OK. If S5 IBHLink is selected, the Advanced connection settings will change. Of course the IBHLink S5 can not be used for S7-PG-functions. With the IBHNet drivers it is only possible to read/write data in an S5-PLC via IBHNet object using Delphi, VisualBasic a.s.o.. For using PG functions with S5 software separate drivers are supplied with the IBHLink S5. Enter the port you setup on 3.2 in the field S5-PG-Port.

12 A valid licence need to be entered in order to use the IBHLink S5. The licence information is supplied with the IBHLink S5. To enter the licence information press Enter registration. It will open the following dialog: Attention: Minimum requirements are at least default user rights to complete this step successfully. Enter your name and company. In the field Serial number enter the serial number of the IBHLink S5 in the following format: S5L-XXXXXX-XXXX. Then enter the PIN supplied with your IBHLink S5. If you do not have a valid serial number and/or PIN code, please contact our support. If all information is correct, Add licence will activate itself. To apply your registrations press this button. Attention: Every serial number can be entered only once. With a click on Exit all entered changes are committed, if the dialog is closed by pressing [x] all changes are lost. By clicking Language in the IBH Network settings window, the user interface language can be chosen. The software needs to be restarted to apply the changes. After all names for the PLC have been defined, these can be chosen by selecting the symbolic name, since the IP address is assigned to that name. The dialog below shows, how to select a PLC from STEP 7.

13 5.0 Settings within STEP 7 Once the installation and configuration of the IBHNet driver has been completed successfully, please run your copy of STEP 7. To choose IBHNet as communication driver, select Extras Set PG/PC interface from the STEP 7 menu bar. Alternatively "Set PG/PC interface can also be accessed via the Windows control panel. Starting with Version 1.19 of the IBHNet network driver, the installation of the Siemens driver for the PC-Adapter (MPI) for the Siemens STEP 7 software is not required any more. It simply appears in the list.

14 Select IBHNet as your default communication driver. Click properties to select an already defined PLC or IBH Network Settings to define a new name for a PLC. Confirm your selection by clicking OK. When closing the dialog Set PG/PC interface, STEP 7 will inform you that driver selections have been altered.

15 If you are using an IBHLink, the configuration is now complete. If a SoftPLC in the version 2.x is used, the option TCP/IP (available starting with version 2.10) needs to be selected. To apply the settings, the SoftPLC needs to be restarted.

16 With the current Version 3.x of the SoftPLC the TCP/IP protocols are ON by default. A separate driver installation and/or configuration is not required with the SoftPLC Version 3.x. All required settings are completed. The PLC can now be reached by the Simatic Manager via the IBHLink. Access to the PLC or the SoftPLC will now be performed via TCP/IP.

17 The IBHLink displays the real MPI respectively Profibus address of the PLC. To work with hardware PLC as you would with a PC Adaptor the address of the CPU need to be selected. The SoftPLC always shows the MPI address 2. Work with the Simatic Manager, as you are used to.

18 6.0 Settings within STEP 7 MicroWin starting with V3.1 SP2 After successful installation and configuration of the IBHNet driver, please run your copy of STEP 7 MicroWin. For configuring please select View-Communication Alternatively you can also select Communication from the left bar. If STEP 7 MicroWin is installed on the operating systems Windows NT4, Windows 2000 and Windows XP, the Siemens driver for the PC-Adapter (MPI) needs to be installed. If the PC-Adapter (MPI) is not installed, the IBHNet network driver will not show in the list.

19 Double click on the adaptor, which is displayed as a circuit board to open the dialog Set PG/PC interface. Select IBHNet(PPI) as desired driver. Click Properties to select an already configured PLC or, via IBH Network settings add a new PLC to the list. Save your settings by confirming Ok. All required settings are completed. The PLC can now be reached by the STEP 7 MicroWin software via the IBHLink. Access to the PLC will now be performed via TCP/IP

20 The IBHLink shows the real address of the PLC. In order to work with the PLC, you need to select the PPI address, you want to work with. Then you can work with STEP 7 MicroWin as usual. There is one difference, if the baudrate of the CPU changes, because the SDB has been transferred to the CPU with a different setting in the baudrate. At the end of the transmission, the communication will fail due to the changed baudrate. However, the transmission has been completed successfully. Disconnect the IBHLink from the PLC and terminate STEP 7 MicroWin. After restarting STEP 7 MicroWin first of all, the adaptor has to be set to the new baudrate, prior to any access to the plc. At this pint, it is a good idea to verify all settings and to make sure - confirm these.

32 10.0 RFC1006 Communication In order to communicate via RFC1006 with the IBH Link S7 or IBH Link S7 Plus like with a Siemens CP343/443, the "RFC1006 to IBHLink" converter service can be started on the local PC or on a PC in the network. Visualizations (HMI) or other applications, that would normally communicate via RFC1006 with a Siemens CP343/443 can talk to the IBH Link S7 or IBH Link S7 Plus this way. The connection will be established from the HMI to the PC with the "RFC1006 to IBHLink" converter service. The converter translates the requests into the IBH Link S7 or IBH Link S7 Plus protocol and routes them to the PLC. The RFC communication takes place via the TCP Port 102. The Siemens "SIMATIC IEPG Help Service (s7oiehsx.exe)" or the CP emulation of the IBHsoftec S7-SoftPLC may have already occupied this port. Make sure the port is free. Starting the RFC to IBHLink converter via the Start menu enables configuration. Clicking the icon left to the clock in the taskbar opens the configuration dialogs. If configuration is finished, the startup of the service can be set to "Automatic" with the Windows service control manager "Control Panel - Administrative Tools - Services". If started as service, only status dialogs can be opened. To go back to configuration, the Service must be stopped and the converter must be started via the Windows Start menu. To create a connection, click "Create/Edit conection". Connections can be exported and also be imported. The dialog below is used to Create/Edit connections:

33 The RFC1006 communication defines TSAPs to identify connection definitions. Normally those are set up as a combination of Rack/Slot number of the PLC and the HMI. User defined TSAPs are also possible. The assignement between the TSAPs to the connected IBHNet station and its relative PLC must be unique. If unsure which TSAPs are sent by the Visualization/HMI, the user can try to establish a connection from the HMI to the "RFC1006 to IBHLink converter" service. It shows the last requested TSAPS from the HMI in the configuration dialog. Accepting these TSAPs into the current configuration is also possible. The "RFC1006 to IBHLink converter" is ready, as soon as all configuration dialogs were exited with "OK". The status dialog shows the currently established connections and a telegram counter.

39 13.0 Troubleshooting Q: The property dialogs will not show in the Simatic Manager: A: Make sure, that you had administrative rights during installation. After the installation, the PC must be restarted. Make sure to have at least version 5.1 of the Simatic Manager. Run the MS-DOS prompt and go to the installation folder of the IBHNet driver, normally \WINNT\SYSTEM32 or \WINDOWS\SYSTEM. Type the following commands: Regsvr32.exe ibh_netpd.dll Regsvr32.exe ibh_netpdl.dll Regsvr32.exe ibh_netpdldp.dll Regsvr32.exe ibh_netpdlppi.dll Regsvr32.exe ibh_netspl.dll Regsvr32.exe ibhnet.dll As result a message box should show "Dll Register Server Succeeded". Run the program IBH_Netpcom.exe with the option RegServer. Example: C:\Winnt\System32> IBH_NETPCOM.EXE -RegServer No error message should appear. Q: With some older versions of Windows 95, the file IBH_NetPcom.exe can not be correctly registered during installation. A: Your Windows95 lacks the Update for Windows Sockets 2. This can be downloaded from Microsoft free of charge. The filename is: W95ws2setup.exe Q: When accessing a PLC, I get an error message. A: Make sure, that the IP address is correctly entered in the driver settings. If a SoftPLC is used, make sure to have TCP/IP selected in the SoftPLC dialog box. With the command PING <IP address> from the MS-DOS prompt, verify that the IBHLink respectively the PC that holds the SoftPLC can be reached via the Ethernet network. Q: When using a SoftPLC, no Stations are displayed in the Simatic Manager. A: Make sure to have TCP/IP selected in the SoftPLC dialog box. Altering the settings require a restart of the SoftPLC to apply the settings. If no changes are applied, probably the file PLC43.INI in the installation folder of the SoftPLC is write protected. Q: The driver IBHNet does not show in the properties dialog Set PG/PC interface of the STEP7 software. A: Install the driver for the serial adaptor PC-Adaptor (MPI), since this adaptor preinstalls basic functions required by the IBHNet driver. Q: In the properties dialog of the STEP7 software, the no properties for the IBHNet can be opened: A: During the installation pathnames have been used, that do not match the MS-DOS 8.3 convention. The name of the installation path must not have spaces and/or other special characters.

40 Q: During the transfer with ProTool I get the message Server is busy, and it looks as if ProTool hangs. A: The timeout for the IBHLink is set to a too high value. If the timeout is > 4 seconds, this message may show up. Q: The adaptor is connected to the profibus, but there are no online functions possible. A: Verify the timing parameters for the Profibus in the Step7 project. Look at the properties of your profibus and write down the timing parameters. Enter the values read from the Step7 project in the advanced screen of the baudrate settings for the IBHLink adaptor. If there is still no online communication possible, increase the parameter Ttr (Target Rotation Time) as well in the IBHLink and on the CPU by means Technical Data IBH-Link S7 The IBHLink is an ethernet gateway. IBHLink fits in a DSub-housing. It consists of a complete fieldbus master together with a 10/100 MBit/s ethernet interface which uses Auto-Negotiation to determine the speed of the network ist is connected to. Due to the design in a D-Sub housing the IBHLink can be directly attached on the fieldbus-connector of a MPI-capable device. The IBHLink is connected to the next hub or switch by a 3m long STP-cable. To connect the IBHLink directly to a PC, you have to use a cross-over cable. The IBHLink is directly supplied over its MPI interface. The configuration takes place over ethernet. Therefore you have to start IBHNet on a PC which is connected to the same ethernet segment like the IBHLink. A diagnosis channel to the IBHLink is established over a defined TCP/IP port. The configuration is stored in a flash memory inside the IBHLink.

The IBHLink is directly attached on the MPI interface of the device. No external power supply is needed, the IBHLink is supplied by the MPI interface. Attention - Due to its compact size, the IBHLink does not have a reverse voltage protection! - Some PLCs may have a temporary error condition on the the MPI/Profibus for the startup period of the internal profibus chip, if the IBHLink is connected in an angular position. If the IBHLink needs to be connected to a PLC that reacts sensitive to this behaviour, the IBHLink must only be connected in powerless state of the PLC.
