0...11 here remain free, as they are already assigned by DO2 and DO3.
Send slots PZD 16 to 31 are not required for this telegram and are therefore filled with a
zero.
1.
For double words (e.g. 1 + 2), assign two consecutive send slots, e.g.
p2061[1] => p8871[1] = PZD 2 and p8871[2] = PZD 3.
2. Enter the following PZD into the next parameter slots of p2051[x] or p2061[2x].
3. Populate the unused slots of p8871[0...31] with zeros.
4. The sequence of the PZDs in the send telegram of this node are defined in parameter
p8871[0...31] by the entries in the required slots.
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 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…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.
