4.10.10.2 Connecting the PROFINET cable to the converter
Procedure
1. Integrate the converter in the bus system (e.g. ring topology) of the control using PROFINET
cables and the two PROFINET sockets X150-P1 and X150-P2.
Overview of the interfaces (Page82)
The maximum permitted cable length from the previous station and to the next one is 100 m.
2. Externally supply the converter with 24VDC through terminals 31 and 32.
The external 24 V supply is only required if communications with the control should also run
when the line voltage is switched o.
You have connected the converter to the control system via PROFINET.
❒
Communication with the control system even if the line voltage is switched o
You must supply the converter with 24VDC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched o.
In the case of brief interruptions of the 24 V power supply, the converter may signal a fault
without communications with the control system being interrupted.
4.10.10.3 What do you have to set for communication via PROFINET?
Conguring PROFINET communication in the I/O controller
You require the appropriate engineering system to congure PROFINET communication in the IO
controller.
If required, load the GSDML le of the converter into the engineering system.
Installing GSDML (Page112)
Device name
In addition to the MAC address and IP address, PROFINET also uses the device name to identify
PROFINET devices (Device name). The device name must be unique across the PROFINET
network.
To assign the device name, you need an engineering software, e.g.HW-Cong.
The converter saves the device name on the inserted memory card.
IP address
In addition to the device name, PROFINET also uses an IP address.
You have the following options to specify the IP address of the converter:
• You specify the IP address using engineering software, e.g.via HW Cong.
• The IO Controller assigns an IP address to the converter.
