↓
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

↓
You may have configured an incorrect unit type or defined the configuration
incorrectly.
↓
Delete the configuration for the MOVI-PLC
®
advanced
DHF41B controller
