*1
The number of expansible modules does not include expansion interface modules.
*2 The numbers in parentheses indicate the number of expansible modules and number of I/O
points when the FC5A series is combined with the expansion interface module (unibody type)
FC6A-EXM2 series.
*3 The numbers in parentheses indicate the number of expansible modules and number of I/O
points when the expansion interface module (unibody type) FC6A-EXM2 series and the
expansion interface module (separate type master) FC6A-EXM1M series are combined with the
expansion interface module (separate type slave) FC6A-EXM1S series.
