Receiving data
The sent telegrams of all nodes are simultaneously available at the SINAMICS Link. Each
telegram has a length of 32 PZD. 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 32 PZD.
Note
The first word of the receive data
If you have not de
activated 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…31] enter the address of the node for which you want to read one
or more PZDs (e.g. p8872[3] = 1 → from node 1, read in PZD 4, p8872[15] = 0 → do not
read in PZD 16).
2. After setting the parameters, using parameter r2050[0…31] or r2060[0…31] you can read
out the values.
