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]

↓
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.

®
advanced
DHF41B controller is currently exchanging data
cyclically with the DP master.
[C]
The MOVI-PLC
®
advanced
DHF41B controller does
not
