6.2 Diagnostic procedure for PROFIBUS-DP
Diagnostic problem: The MOVI-PLC
®
advanced DHF41B controller is
not working on the PROFIBUS.
Initial status:
• The MOVI-PLC
®
advanced DHF41B controller is physically connected
to the PROFIBUS.
• The MOVI-PLC
®
advanced DHF41B controller was configured in the
DP master and bus communication is active.

FLASHES
↓
The MOVI-PLC
®
advanced DHF41B controller recognizes the baud rate,
but was either not configured in the DP master or it was configured incor-
rectly.
↓
Check whether the configured PROFIBUS address is the same as the
address set on the DIP switches.
↓
PROFIBUS addresses identical? No → [D]
Yes
↓
You may have configured an incorrect unit type or defined the configuration
incorrectly.
↓
Delete the configuration for the MOVI-PLC
®
advanced DHF41B controller
from the DP network.
↓
Configure the MOVI-PLC
®
advanced DHF41B controller again, choosing
the unit designation 'MOVI-PLC'.
Use a predefined configuration to simplify the process. Do not change any
of the preset configuration data!
Assign the address range for your control system.
↓
Load the configuration in the DP master and start the bus communication
again.
[A] Check the bus cabling.
[B] The MOVI-PLC
®
advanced DHF41B controller is currently exchanging data
cyclically with the DP master.
[C] The MOVI-PLC
®
advanced DHF41B controller does not recognize the
baud rate!
Check the bus cabling.
[D] Adapt the bus addresses.
