Remedy
Check the supply voltage or turn it on at the
interface module.*
---
Activate the interface module with the con-
figuration software or the user program.
Configure the interface module with the
configuration software.
---
---
Evaluate the diagnostics and eliminate the
error.
Check the structure of the ET 200SP to see
whether a module is missing or defective,
or whether a non-configured module is
inserted.
See section Invalid configuration states of
the ET 200SP on PROFINET IO (Page 45).
Evaluate the display of the module status in
STEP 7 and eliminate the error in the re-
spective I/O module.
See section Maintenance events
(Page 41).
---
Run a firmware update. If the error persists,
contact Siemens Industry Online Support.
Replace the interface module.
