The objects mapped to PDOs can be changed only when the EtherCAT (CoE) Network Module is in the
Pre-Operational state.
There are 4 receiving PDOs (RxPDOs) and 4 transmit PDOs (TxPDOs). Each PDO Mapping can be
assigned up to 8 objects, and the total assignment is not more than 32 bytes.
The procedure of PDO mapping is as following:
1.
Disable the assignments between the Sync Manager and PDOs:
Set subindex 00h in objects 1C12h and 1C13h to 0.
2.
Disable the assignments of PDOs:
Set subindex 00h in objects (1600h to 1603h) and (1A00h to 1A03h) to 0.
3.
Set all of the mapping entries for the PDO mapping objects:
Set objects (1600h to 1603h) and (1A00h to 1A03h).
4.
Set the number of mapping entries for the PDO mapping objects:
Set subindex 00h in objects (1600h to 1603h) and (1A00h to 1A03h).
5.
Set the assignments between the Sync Manager and PDOs:
Set subindex 01h in objects 1C12h and 1C13h.
6.
Enable the assignments between the Sync Manager and PDOs:
Set subindex 00h in objects 1C12h and 1C13h to 1.
