6.4 PLC I/O Interface based on PROFINET
Pin assignment PN1, PN2
Pin Signal name Signal type Meaning
1 TX+ O Transmit data +
2 TX- O Transmit data -
3 RX+ I Receive data +
4 N.C. - Not assigned
5 N.C. - Not assigned
6 RX- I Receive data -
7 N.C. - Not assigned
8 N.C. - Not assigned
The interfaces have the following properties:
● The interfaces are designed for full-duplex mode; in other words, the ports can both transmit
and receive.
● The two 100 Mbit Ethernet ports and the internal Ethernet controller are connected to an
integrated 3-port switch. The MAC address of the Ethernet controller is stamped on the
type plate.
Wiring the PLC I/O Interface
Interfaces PN1 and PN2 can be used to establish the PLC I/O Interface communication
network, which is based on PROFINET IO:
● To connect a machine control panel (MCP 310C PN, MCP 483C PN or MCP Interface PN)
● To connect to the PLC I/Os
Note
The PPU has one MAC address for both PLC I/O Interface ports that is the printed on the
type plate of the PPU, see section "Type plate (Page 25)". The same applies for the MAC
addresses of the operator components.
When connecting I/O devices (I/O modules, machine control panel) to the I/O Controller (PPU),
please use the pre-assembled SINAMICS S120 DRIVE-CLiQ signal cables; from a technical
point of view, these are also suitable for use with PLC I/O Interface.
