9.3.8 Data transmission between I/O system IP20 and controller
In the Lenze setting of the I/O system IP20, the basic identifiers of the PDOs are
set for the communication protocol "system bus (CAN)".
For communicating with Lenze controllers the basic identifiers for the process data
object 1 must be adapted.
1. Set PDO1−Rx via index 1400
h
, subindex 1 to 770.
2. Set PDO1−Tx via index 1800
h
, subindex 1 to 769.
3. Make a reset node by setting the index I2358h = 1. The settings are
accepted.
