(4) Expansion equipment newly available with the FX3UC series
When main units are changed from FX2NC series to FX3UC series, the following FX3 series expansion
equipment can be used.
Since FX3 series special adapters do not consume any inputs or output points, they can be added without
affecting the number of I/O points.
System performance can be increased over that of the existing system by using equipment available for
the FX
3UC series.
