8.3.3 Assigning individual parameters
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 I1400
h
, subindex 1 ... I1409
h
,
subindex 1.
Process data objects for output data
Individual identifier for output data can be set via the indices I1800
h
, subindex 1 ... I1809
h
,
subindex 1.

Note!
ƒ Set the value which makes the required identifier (x = corresponding process
data object) in index I140x
h
, subindex 1 or I180x
h
, subindex 1.
ƒ Make a reset node so that the changes are accepted,
8.3.4 Process data transmission mode
Transmission mode for process input data
The transmission mode is configured via the index I1400
h
, subindex 2 (PDO1−Rx) ... I1409
h
,
subindex 2 (PDO10−Rx):
ƒ Sync−controlled reception
ƒ n−sync−controlled reception
– First, a certain number (n) of sync telegrams must be transmitted (I140x
h
,
subindex 2 = 1 ... 240). Then the PDO telegram must be received from the master.
Finally, the process input data are accepted.
ƒ Event−controlled reception (Lenze setting)
Transmission mode for process output data
The transmission mode is configured via the index I1800
h
, subindex 2 (PDO1−Tx) ... I1809
h
,
subindex 2 (PDO10−Tx):
ƒ Sync−controlled transmission
ƒ n−sync−controlled transmission
– First, a certain number (n) of sync telegrams must be transmitted (I180x
h
,
subindex 2 = 2 ... 240). Then, the PDO telegram is transmitted to the master.
ƒ Event−controlled transmission (Lenze setting)

Note!
After changing to the CAN state "Operational", the current process image is
transmitted from the I/O system.
