Accessing Parameters
DeviceNet explicit messages sent from the Master Unit to the
3G3AX-MX2-DRT-E Unit can be used to access any parameter from the Unit
or the MX2-A
@
Inverter. Please refer to the
APPENDIX E DeviceNet Explicit
Messages
on page 71 for details and examples.
Refer to the DeviceNet Master Units Operation manual (Cat. No. W380) for
details on how to send the explicit messages to the 3G3AX-MX2-DRT-E.
Below are examples for usage of the OMRON CJ1W-DRM21 Master Unit with
the FINS Explicit Message Send command (2801).
