5.3.9 Additional notes on the modules 1...8
For the CANopen protocol, communication is done in blocks, the so-called PDOs (Process Data
Object). Each PDO contains 8 bytes of user data. In the PDO the digital data of the slaves is displayed
as follows:
Byte 0 Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7
PDO 7 4 3 0 7 4 3 0 7 4 3 0 7 4 3 0 7 4 3 0 7 4 3 0 7 4 3 0 7 4 3 0

We recommend to set the setting values of the modules 1...8 to even values, otherwise a byte offset
might occur in the following modules.
