[etherlab-users] Beckhoff 4102 ecrt_slave_config_dc

[james.rowland at diamond.ac.uk]

Hello

Using master 1.5 from hg:

I can't configure the SYNC signals for this slave, the AssignActivate
value is 0x700 from the Beckhoff XML.

ecrt_slave_config_dc(sc, 0x700, PERIOD_NS, 0, 0, 0);

dmesg:
EtherCAT ERROR 0-10: Failed to set OP state, slave refused state change
(SAFEOP + ERROR).
EtherCAT ERROR 0-10: AL status message 0x0032: "PLL error".

I can't find any documentation on how to configure these registers from
Beckhoff or the Ethercat standards, has anyone been able to use the DC
sync on these devices from Linux?

James
