Connecting
MOVI-PLC
®
/
PROFIBUS
As a rule, the MOVI-PLC
®
advanced
DHF41B control card is connected to the
PROFIBUS system using a shielded twisted-pair cable. Observe the maximum
supported transmission rate when selecting the bus connector.
The twisted-pair cable is connected to the PROFIBUS connector at pin 3 (RxD/TxD-P)
and pin 8 (RxD/TxD-N). Communication takes place using these two pins. The RS485
signals RxD/TxD-P and RxD/TxD-N must all be connected to the same contacts in all
PROFIBUS stations. Else, the bus components cannot communicate via the bus
medium.
The PROFIBUS interface sends a TTL control signal for a repeater or fiber optic adapter
(reference = pin 9) via pin 4 (CNTR-P).
Baud rates
greater than
1.5 MBaud
MOVI-PLC
®
advanced
DHF41B with baud rates > 1.5 MBaud can only be operated with
special 12 MBaud PROFIBUS connectors.
Bus termination
If MOVI-PLC
®
advanced
DHF41B is located at the start or end of a PROFIBUS segment
and if there is only one PROFIBUS cable connected to MOVI-PLC
®
advanced
DHF41B,
you must use a connector with an integrated bus terminating resistor.
Switch on the bus terminating resistors for this PROFIBUS connector.
Setting the
station address

on MOVI-PLC

advanced
DHF41B.
The MOVI-PLC
®
advanced
DHF41B controller supports the address range 0 - 125.
Any change made to the PROFIBUS station address during operation does not take
effect immediately. You must restart the inverter with the MOVI-PLC
®
advanced
DHF41B control card for the changes to take effect (power + 24 V off/on).
