Ethercat modes

Other Parts Discussed in Thread: AM3359

Hi,

we are using AM3359 ICE Board "Ecatappl"

Ethercat operates in 3 modes

1)Asynchronous mode ( Free run)

2)Synchronous mode (Sm-sync)

3)DC Mode

"Ecat application" is defined to work in Synchronous mode

If master communicates with slave in Asynchronous mode (when slave is configured with synchronous mode)

Will both Asynchronous and Synchronous modes of communication can take place from master (when slave is configured with synchronous mode)?

Regards,

Bindu

    Hi,

    As per my understanding as stated before here,

    Master select between DC SYNC mode and SM-sync/Free Run mode

    SM-sync or Free run mode depends on slave configuration, see details below

    One can’t differentiate between FreeRun/SM-sync mode from the master side

    FreeRun mode selection from master alone does not guarantee ASYNC mode of operation at slave as it depends on slave configuration.

    I recommend to post to ETG forums for further clarification on TwinCAT and SSC usage.
