Configuring Modbus Tcp Via Interface X150 - Siemens SINAMICS G130 Operating Instructions Manual

Drive object that can be addressed via Modbus
With Modbus TCP, you always address drive object DO1 from the list of drive objects
(p0978[0]). A vector drive object must be in this parameter.
However, Modbus TCP is only activated if, under p0978[0], there is a drive object that is
supported by Modbus TCP. If p0978[0] does not contain a valid drive object, then
establishing communication is acknowledged with Alarm A08555.

Configuring Modbus TCP via interface X150

Activate Modbus TCP via X150 (CU320-2 PN)
1. For drive object DO1, set p2030 = 13 (Modbus TCP).
2. Using p8921, set the IP address for the onboard PROFINET interface on the Control Unit.
3. Set the standard gateway using p8922.
4. Set the subnet mask using p8923.
5. Set the DHCP mode using p8924.
6. Select the setting "Activate and save configuration" as interface configuration using
p8945 = 2.
7. In the STARTER commissioning tool, check the list of drive object p0978.
When required, change the sequence of the drive objects using the telegram
configuration ("Drive device" > "Communication" > "Telegram configuration").
8. Save the settings in the STARTER commissioning tool and carry out a POWER ON.
