Defining the send data
Define the send data from node 1 (Control Unit and drive object 1). Control word STW1,
speed setpoint and torque setpoint should be sent from drive object 1:
1. Place parameter r0898 in send parameter p2051[0]. p2051[0] is written to the send slot
2. Because parameter r0062 is 32 bits long, place r0062 in send parameter p2061[1].
3. Because parameter r0079 is 32 bits long, place r0079 in send parameter p2061[3].
4. The remaining slots remain empty.

Define the send data from node 2 (drive object 2). Status word ZSW1, speed and torque
actual values should be sent from drive object 2:
1. Place parameter r0899 in send parameter p2051[0]. p2051[0] is written to the send slot
2. Because parameter r0021 is 32 bits long, place r0021 in send parameter p2061[1].
3. Parameter r0031 is also 32 bits long. Therefore, place r0031 in send parameter p2061[3].
4. The remaining slots remain empty.
