Expansion Card EtherCAT

Usable with S300, S600


The expansion card can be used with S300 (with HWR<3.99) and S600. The card could be used with S700, too, bus this wouldn't make sense, because S700 devices have EtherCAT onboard.
S300 devices with HWR>=4.00 are available as EtherCAT devices with built-in EtherCAT option. These products don't require an additional expansion card, but the expansion slot is blocked nevertheless.
Connection to the EtherCAT network via RJ-45 connectors (IN and OUT interfaces).
CAN over EtherCAT (CoE) is used. Device description for TwinCat can be downloaded from File Selector, set filter document type to "Fieldbus Support".
The matching manual can be found via the File Selector.
The command OPTION delivers a code for the built-in expansion card.
