Configuring Modbus TCP via interface X150
Activate Modbus TCP via X150 (CU320-2 PN or CU310-2 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 "Activate and save configuration" as interface configuration using p8925 = 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.
Modbus settings with interface X150
Using the following parameters, set the communication for Modbus TCP with a X150
interface:
p2040 Setting the monitoring time to monitor the received process data via fieldbus inter-
face.
If process data is not transferred within one cycle of the fieldbus monitoring time,
then the drive shuts down with fault F01910.
r2050[0...19] Connector output to interconnect the PZD received from the fieldbus controller via
p2051[0...24] Selects the PZD (actual values) to be sent to the fieldbus controller in the word
r2053[0...24] Displays the PZD (actual values) sent to the fieldbus controller in the word format
Status display for the internal communication interface.
p8839[0...1]
Assigning the PN onboard interface (x150) via PZD interface 1 (IF1) and interface 2
(IF2).
r8850[0...19] Connector output to interconnect the PZD (setpoints) received in the word format
Selects the PZD (actual values) to be sent in the word format via IF2.
Displays the PZD (actual values) sent in the word format via IF2.
Status display for COMM BOARD.
