Hardware interface

Hardware interface
Two communication modules are available for the connection of PROFIBUS-DP to the devices
7SJ61, 7SJ62, 7SJ63, 6MD63 and 7UM61:
•
PROFIBUS module with isolated RS485 interface (PSE module),
•
PROFIBUS module with fibre-optical interface (PSO module).
7.1

Technical data of the connection via the PSE module

Connections 9-pole D-SUB outlet (ref. to Table 7-2 )
Protocol semi-duplex
Max. line length
(depending on the
transmission rate)
Insulation level 500 V
Bus termination Integrated, connectable terminating resistors
221 Ohm between RxD/TxD-P (B) and RxD/TxD-N (A)
392 Ohm between RxD/TxD-P (B) and VCC1 as well as RxD/TxD-N (A) and GND1
Input resistor not terminated ≥ 10 kOhm, then bus termation via bus plug with integrated
terminating resistors.
Level Transmitter:
Low: -5 V ≤ U
High: +5 V ≥ U
Receiver:
Low: U
High: U
Transmitter and receiver are surge-proof for voltages between A and GND1 as well as
between B and GND1 in the range of –7 V...+12 V.
Cable Bus cable type A according to EN 50170, twisted and screened.
SIMATIC NET PROFIBUS 6XV1 830
Plug SIMATIC bus connection plug for PROFIBUS 6GK1 500-0EA02 with axial cable output,
resistor combination integrated and connectable by sliding switch.
Dimensions (B x H x T)
Depth incl. cable bending radius
Note:
When angle plugs or plugs with non-axial output are used, then the direction of the outgoing
cable has to be coordinated with neighbouring terminals and plugs.

Max. number of
32
modules at the bus
Table 7-1 Technical data of the connection via the PSE module
1
For exclusive utilisation of PSE modules at the bus. This value could be smaller depending on the used PROFIBUS-
DP master and further modules at the bus. If more than 32 devices at the bus are needed, RS485 repeaters (e.g.
6ES7 972-0AA00-0XA0) have to be used.
