DeviceNet Adapter for use with DPI AC Drives

E.2 M-S Output Parameter Configurations

M-S Output (26) has five configurable bits as shown in figure E.2.

When you enable Cmd/Ref or Datalink in the adapter, you must set
the corresponding bit in M-S Output (26) if you want the output data
to be sent to the scanner or master device.

Tables E.3 and E.4 list possible configurations for M-S Output (26)
and the possible data size allocation associated with each value
depending on the method of data transfer.
