SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
The serial RS485 interface is used to connect several ”SIMODRIVE
611 universal” control boards in an RS485 group.
The SimoCom U parameterizing and start–up tool communicates, in
the online mode, via an RS232/RS485 interface converter and the se-
lected drive in the RS485 group (refer to Fig. 3-10).
Notice
The RS485 interface can only function with control boards from the
appropriate hardware version (refer to Order No., MLFB).
Control board (Order No.) RS485?
6SN1118–N00–0AA0 RS485 cannot be used
from 6SN1118–N00–0AA1 RS485 can be used
: Space retainer for the Order No.
For communications via RS485, the following should be observed:
1. Parameters
– P0801 (toggling between RS232/RS485)
The parameter must be set to RS485 (P0801 = 1).
Recommendation:
Set or check this parameter using the display and operator panel
(refer to Chapter 3.2).
– P0802 (drive number for RS485)
The drive number for each drive is selected via this parameter.
2. Interface converter RS232/RS485
For operation via RS485, a commercially available RS232/RS485
converter is required between the PC and RS485 bus.
The interface converter must have the following features:
– The converter itself must automatically change over the data flow
direction.
– It is not permissible that the converter sends an ”echo” back to
the PC.
Recommended RS232/RS485 interface converter name:
– Name: PC/PPI cable (RS232/RS485 converter)
– Order No.: 6ES7 901–3BF20–0XA0
– Cable length: 5 m
– Connector: on the RS232 side: 9–pin socket connector
on the RS485 side: 9–pin plug connector
– Power supply: via the connector on the RS485 side
RS485 side (+24 V/0.5 W)
– Data transfer rate: set to 38.4 kbaud
