Hi,
I seem to have a similar problem. This line:
ecrt_slave_config_dc(sc, 0x0700, (uint32_t)interval, 400000,
(uint32_t)interval, 100000);
(interval is 1000000 for 1 ms).
puts off my EL4102: it stops responding at all.
I know that some modules don't like zeroes for the last three values, so
you may want to experiment there. But there is little documentation
available. Anyone out there that has info about this?
A value of 0x0100 in the line above instead of 0x0700 keeps my EL4102
happy, but I am not sure how to test that this gives me what I want.
Len.

Subject: [etherlab-users] Beckhoff 4102 ecrt_slave_config_dc
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
