Settings
The MW100 channels are assigned to the MV external input channels as follows:
• Channel numbers
The channels of the MW100 selected first are assigned consecutively to external
input channels from 201. The channels of the MW100 selected next are assigned
consecutively to the available external input channels from the smallest number. You
cannot select the target external input channels.

• 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 MV
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, the 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 10 channels at a time 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 assigned is greater
than the number of available external input channels.
• If the range setting of a MW100 channel is set to “SKIP,” the corresponding MV external
input channel is set to “OFF.”
• If a MW100 unit contains a module that cannot be assigned automatically, only the channels
that can be assigned are assigned to the MV external input channels.
• If a new MW100 is added, auto setting is executed again. Because all the settings are
cleared, you must execute auto setting again for all MW100s.
• If you are connecting MW100s that can be automatically assigned along with MW100s
that cannot be automatically assigned or other Modbus devices, automatically assign the
MW100s that can be automatically assigned first and then manually assign the remaining
devices.
