Integrating inverters into PROFINET
Procedure
To connect the inverter to a control via PROFINET, proceed as follows:
1. Integrate the inverter in the bus system (e.g. ring topology) of the control using
PROFINET cables and the two PROFINET sockets X150-P1 and X150-P2.
Fieldbus interface allocation (Page 92)
The maximum permitted cable length from the previous station and to the next one is 100
m.
2. Externally supply the inverter with 24 VDC 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 off.
You have connected the inverter to the control using PROFINET.
4.7.1.3
Configuring communication to the control
Configuring the communication with a SIMATIC S7 control
You have the following options, if the inverter is not included in the hardware library:
● Install the most up to date STARTER version
● Install the GSDML of the inverter using “Tools/Install GSDML file" in HW Config.
Further information is provided in the Fieldbus function manual.
Overview of the manuals (Page 507)
Configuring the communication with a non-Siemens control
1. Import the device file (GSDML) of the inverter into the engineering tool for your control
system.
2. Configure the communication.
