Troubleshooting

5.1. Why Does the Plug Icon Not Have a Green Background Even
Though the Device Is Connected Properly?
The plug icon is green when data is exchanged.
As soon as you view the measured value, the plug will have a green background,
provided the connection is error-free.
( Module → Measured Value → Show Measured Value)
5.2. Why Does the Error Message "No available space to add the
module" Appear?
Check that the correct backplane has been set.
In the case of redundant LB backplanes (e.g., LB 9022), I/O modules may only be
added from slot 03 onward (if the numbering begins with 0).
Slot 01 and slot 02 must be configured as empty slots.

5.3. Why Does the Error Message "Base unit overloaded" Appear?

Check the settings of the power supplies.
Additional power supplies may be required to power the I/O modules.
Alternatively, the position of the modules in the station can be changed or
your system can be expanded with another station.

5.4. Why Does the Topology Scan Not Run Successfully?

Check the PROFIBUS address of the com unit and the physical
connection. The topology scan is only possible when no modules are scheduled.
Therefore, no more modules may be added to the module tree below the com unit in
PACTware.
Also ensure the backplane is configured correctly.
