[etherlab-users] PDO mapping?

Hello again!

I have another batch of questions, which may look obvious to an
experienced user.
My application was compiled and loaded.
Now I see this in my log file:

Started RT timer at a rate of 10000us
Application tid 0 running at 10000us
Successfully registered application "t1" with RT-AppCore.
EtherCAT WARNING: 1 datagram UNMATCHED!
EtherCAT WARNING: Slave 1 does not support changing the PDO mapping!
EtherCAT WARNING: Failed to configure mapping of PDO 0x1600.
EtherCAT WARNING: Slave 1 does not support changing the PDO mapping!
EtherCAT WARNING: Failed to configure mapping of PDO 0x1601.
EtherCAT: Domain 0: Working counter changed to 1/1.
EtherCAT: Slave states: PREOP, OP.

Note the warning. Also I try to set a sampling rate 100[Hz]. I wonder
what may be the sampling rate of my application in reality.

I try to output a constant signal 1 to my slave, I think this should
correspond to 10[V] output, but nothing is detected by the multimeter.
Maybe something is not clear with the data scaling?
