Connecting the PROFIBUS cable to the converter

Procedure
1. Connect the converter to socket X126 via a PROFIBUS cable with the higher-level control.
The maximum permitted cable length to the previous station or the subsequent one is 100 m
at a baud rate of 12 Mbit/s.
2. If necessary, connect a 24 V supply voltage to terminals 31 and 32.
The external 24 V supply is only required if communication with the control may not be
interrupted even if the line voltage is switched off.
You connected the converter with the control via PROFIBUS.
❒
Communication with the control system even if the line voltage is switched off
You must supply the converter with 24 V DC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched off.
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.

What do you have to set for communication via PROFIBUS?

Configuring PROFIBUS communication
You require the appropriate engineering system to configure PROFIBUS communication in the
PROFIBUS master.
If required, load the GSD file of the converter into the engineering system.
Setting the address
Set the address of the PROFIBUS device.
