<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>My client has a robotics system using Copley Controls Accelnet Plus
drives with a digital input-triggered capture capability that we're trying to
use for positioning calibration. This feature requires the ability to map
the same slave CoE object for both read to detect the capture event and write
to subsequently rearm the trigger. Mapping this object to both Tx and Rx
PDOs appears to work correctly from the PDO mapping info returned from the
master. However, when I attempt to register the corresponding mapped PDO
entries in the domain, I get the same domain offset for both PDOs, preventing
the application from managing them independently.<o:p></o:p></span></font></p>
