Hi, guys
I have written a program about Beckhoff EL2252. But there are some
problems during running.
The message is showed below.

Hi,
Firstly, there is no way of checking if the frame transfer is complete.
One comment, to reduce the jitter and offset of the master application time,
place the clock_gettime(), ecrt_master_application_time(),
ecrt_master_sync_reference_clock(), ecrt_master_sync_slave_clocks() calls

Note: from your previous email you are also delaying the send to the start of
the next cycle, which adds another cycle of delay.

It's something like

t = 0.0 : master receive datagram 0, receive actual position -2
t = 0.1 : master send datagram 1 (target position 1)

t = 0.5 : drive sync 0, target position 1 becomes active, actual position 0 is
Hello,
I am currently experimenting with the Cyclic Synchronous Position mode of
ELMO drives. I am using EtherLab 1.5.2 from the 1.5.2 branch with
ec_generic on a PREEMPT RT system (kernel 4.14.28).
If I compare the current position the drive reports in the frame I receive
after I send a
Hello,
I am progressing quite well with EtherLab and am currently working on
synchronizing outputs/movement with the Master time. We are using the
Master 1.5.2 from the 1.5.2 branch, ec_generic driver with PREEMPT RT
(kernel 4.14.28).
In our application, we need to be synchronized to the real
Hi,
There was a bug in my example, EC_WRITE_S32 must be used (instead of
EC_WRITE_S16) to set the target velocity.
I have attached the new version that works.
