5.3.3 Assigning individual identifiers
For larger networks with many nodes, it may be useful to set individual identifiers for process data
objects PDO1 ... PDO10, that are independent of the set node address.
Process data objects for input data
Individual identifiers for input data can be set via the indices I-1400, subindex 1 ... I-1409, subindex
1.
Process data objects for output data
Individual identifiers for output data can be set via the indices I-1800, subindex 1 ... I-1809, subindex
1.
5.3.4 Transmission mode for process data
Transmission mode for process input data
The transmission mode is configured via index I-1400, subindex 2 (PDO1-Rx) ... I-1409, subindex 2
(PDO10-Rx):
• Sync-controlled reception
• n-sync-controlled reception
• First, a certain number (n) of sync telegrams must be transmitted (I-140x, subindex 2 = 1 ...
240). Then the PDO telegram must be received from the master. Finally, the process input
data are accepted.
• Event-controlled reception (Lenze setting)
Note!
Set the value which makes the required identifier (x = corresponding process data
object) in index I-140x, subindex 1 or I-180x, subindex 1.
Make a reset node so that the changes are accepted.
