For this example the following objects will need to be set in order to achieve the mappings of the parameters/objects in the PDOs.

The format used to define the value of a mapped object is as follows:

NOTE

 

Bit 0 to 7: Length of the mapped object in bits (if a gap, bit length of the gap).

 

Bit 8 to 15: Sub-index of the mapped object (if a gap, zero).

 

 

 

Bit 16 to 31: Index of the mapped object (if a gap, zero).

 

 

 

The maximum number of mappings in one PDO is five. There are no restrictions on the

NOTE

 

data length of these 5 parameters (i.e. It is possible to map five, 32-bit parameters in

 

one PDO). It is also possible to use a maximum of 2 x RxPDOs and 2 x TxPDOs.

5.1.4Configuring the Sync Managers

The Sync manager is used to control the transmission of CANopen PDOs over the EtherCAT network.

The following objects 0x1C12 - Sync manager 2 PDO assignment (RxPDO) and 0x1C13 - Sync manager 3 PDO assignment (TxPDO) are required to assign PDOs to the synchronization task. For the purpose of the example assign one RxPDO to sync manager 2 and two TxPDOs to sync manager 3.
