How to set POWERLINK between Altivar and B&R PLCs?
Hello, today we will show you how to set up the communication between an Altivar and a B&R PLC
using the POWERLINK Module VW3A3619.
ATV340 + VW3A3619 and CPU 1516-3 PN/DP will be used in this video.
Please refer to the ATV340 Installation manual and the user manual of the POWERLINK card VW3A3619
for the hardware setting and connection.
Open Automation Studio and import the XDD files of the Altivar drives that can be downloaded from Schneider site.
Create a new project and identify the connected PLC.
Configure the IP address of the PLC.
From the hardware catalog, add an ATV340 to the POWERLINK network and change the node number if needed.
With POWERLINK, the drive configuration can be done in the 'Device specific parameters'
and sent every time communication is established.
Expand the 'Device specific parameters' and search for the parameter FR1 [Configuration reference frequency 1].
This parameter allows you to select the source of the command and the reference.
In the 'ATV340_Communication_Parameters_file' that can be downloaded from Schneider site
are given the addresses of all the drive parameters and their possible values.
To send the command and the reference via POWERLINK, FR1 must be set to 169 ([Ref. Freq-Com. Module] (NET)).
Expand the 'Channels' to configure the parameters that will be exchanged cyclically.
In 'Read' mode, select ETA for drive status and RFR for motor speed (in 0.1 Hz).
In 'Write' mode, select CMD for command and LFR for reference (in 0.1 Hz).
Build the project.
Transfer to the PLC.
Open SoMove and connect to the drive.
In Slot A -PowerLink menu in the 'Parameters List' tab, set the node address of the drive, then restart the drive.
In Automation Studio, activate the monitoring and open the I/O mapping of the drive.
'ModuleOk' shows the status of the communication and ETA shows the drive status.
To control the drive, first send the speed reference via LFR (in 0.1 Hz),
then send the sequence 6, 7 and 15 via the control word CMD.
ETA shows the drive status changing and RFR displays the motor speed in (0.1 Hz).
Send 7 in CMD word to stop the motor.
