IBHNet:Troubleshooting
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\SYSTEM32. 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: Does the IBHNet driver work with older versions of Windows® 95 or Windows® NT4?
A: No. The IBHNet driver is built with Microsoft Visual Studio 2005. Microsoft doesen´t support these operating systems any more with their current compilers. Our Support can supply IBHNet version 1.25, which was the last version that worked with these operating systems.
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 IBH Link 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 pre-installs 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.
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 IBH Link 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 Step®7 project. Look at the properties of your profibus and write down the timing parameters. Enter the values read from the Step®7 project in the "advanced" section of the baudrate settings for the IBH Link adaptor. If there is still no online communication possible, increase the parameter "Ttr" (Target Rotation Time) as well in the IBH Link and on the CPU by means.
Q: Searching for IBH Link does not find the connected IBH Links and/or trying to connect to the IBH Link does not work.
A: Finding the IBH Link is made via the UDP ports 25383 and 25384, the connection itself is made through TCP port 1099. A firewall may block the required ports for searching and/or connecting. Open the required ports in the firewall or deactivate the firewall.
