Receiving data
The sent telegrams of all nodes are simultaneously available at the SINAMICS Link. Each
telegram has a length of 16 PDA. Each telegram has a marker of the sender. You select
those PZD that you want to receive for the relevant node from all telegrams. You can
process a maximum of 16 PZD.
Note
If you have not deactivated the evaluation of bit 10 with p2037 = 2, the first word of the
receive data (PZD 1) must be a control word, where bit 10 = 1 is set.
In this example, Control Unit 2 receives selected data from the telegram of Control Unit 1.
Proceed as follows to receive data:
1. In parameter p8872[ 0...15] enter the address of the node for which you want to read one
2. After setting the parameters, you can read out the values via parameters r2050[0...15] or
