Hi all, How do I verify that my distributed clock setup in EtherCAT is correct?
I use SDO 0x1C32/0x1C33 check that the slaves are in DC mode, and use 0x92C reg check the system time difference, here is the result of two slaves connected: # ethercat -p0 -tuint16 upload 0x1C32 1; ethercat -p0 -tuint16 upload 0x1C33 1; ethercat -p0 reg_read 0x92C -t int32; ethercat -p1 reg_read 0x92C -t int32 0x0002 2 0x0002 2 0x007051ea 7361002 0x80000002 -2147483646 The second slave seems to work well, only have 2ns difference, but why does the first slave always report with a large number of the time difference? Is that correct? Thanks, Louie. _______________________________________________ etherlab-users mailing list etherlab-users@etherlab.org http://lists.etherlab.org/mailman/listinfo/etherlab-users
