Troubleshooting
General
In all cases, perform the the following:
1. Verify that your device has the correct module by checking parameters
3.2.10.4.
Smartlinx®Module Type and 3.2.10.5. Smartlinx®Protocol. (See the Parameters
chapter of your Siemens device operating instructions for details.)
2. Check
3.2.10.1. Hardware Status. (See the Parameters chapter of your Siemens device
operating instructions for details.) Below are the possible states:
3. Make sure the Siemens device is set to a unique address to prevent conflict with any
other slave(s) on the bus.
4. Check the configuration of the scanning master to make sure it is functioning
properly.
Device not coming online
If you have configured the Siemens device in the Master and downloaded it to the
processor, but the device is not coming online:
• Check which GSD file you are using to make sure that it is the correct one (see
GSD files on page 9).
• Check the wiring to the module. In particular, check that you have lines A and B
connected correctly.
• Verify that you have set the correct address on the module. Also, please note
that the module does not see a charge until the power has been cycled.
• Verify that the Read and Write block sizes are correct.
Other devices dropping out
If the network was working fine until you connected to the Siemens device, at which time
other devices dropped out:
• Check the termination switch on the PROFIBUS module. The network cable has
to be terminated at both ends of the LAN, but not in between.
• Check your grounding. The PROFIBUS specifications require that all devices be
on the same ground. Improper grounding can cause unpredictable effects.
