Setup Items
The MW100 channels are assigned to the external input channels of the DX as follows:
• Channel Number
The channels of the MW100 selected first are assigned consecutively from external
input channel 201. The channels of the MW100 selected next are assigned to the
available external input channels from the smallest number. You cannot select the
external input channels to be assigned.

• Range Settings
The range settings of the MW100 (including the span and unit) are set automatically
to the external input channels.
If the span setting of the MW100 range exceeds the span setting range of the DX
external input channel (–30000 to 30000), it is set to the span upper limit (30000) or
lower limit (–30000).
Specify the settings such as the alarm, tag, and the area display of the color scale band
of each channel after the auto setting is complete.
Note
Precautions When Assigning Channels to the External Input Channels
• The MW100 channels are assigned in unit of 10 channels to the external input channels. If
the MW100 measurement module consists of less than 10 channels, “OFF” is assigned to
the external input channels for the section without channels.
• An error occurs if the number of MW100 channels to be automatically set is greater than the
number of available external input channels.
• If the range setting of a MW100 channel is set to “SKIP,” the external input channel of the
DX is set to “OFF.”
• If a MW100 unit contains a module that cannot be set automatically, only the channels that
can be assigned are assigned to the external input channels of the DX.
• If a new MW100 is added, auto setting is executed again. At this point, all the settings are
cleared. Therefore, you must execute the auto setting again for all MW100s.
• If you are connecting MW100s that can be automatically set and MW100s that cannot
be automatically set or other Modbus devices, automatically set the MW100s that can be
automatically set first and then manually set the connection of the remaining devices.
