7.14 Setting of Channel No. when Using Multiple Remote I/O Units
When the remote I/O unit is connected with serial links (MC link B), multiple units can be used as long
as the total No. of occupied channels is within 8 channels.

When using multiple remote I/O units, a characteristic station No. must be set for each unit. The
FCUA-DX10* unit has one station No. setting switch, and FCUA-DX11*, DX12*, DX13* and DX14*
units have two switches. Each of these switches must be set to a characteristic station No.
The device address in each unit is determined according to the station No. Use the station No. setting
switch to set the device address.
