Appendix B: Differences with FX2N-32CCL
This appendix describes the major differences between the 64CCL and the FX2N-32CCL.
Appendix B-1 Differences with FX2N-32CCL
• The FX2N-32CCL supports only CC-Link Ver. 1.00. The 64CCL supports CC-Link Ver. 1.10 and CC-Link
Ver. 2.00.
• The FX
2N-32CCL operates as a remote device station. The 64CCL operates as an intelligent device
station. The station type set in the master station is different.
• In the FX
2N-32CCL (CC-Link Ver. 1.00), remote inputs (RX) and remote outputs (RY) are allocated to BFM
#0 to #7, and remote registers (RWr and RWw) are allocated to BFM #8 to #23. The 64CCL holds not only
the buffer memory area compatible with the FX
2N-32CCL but also the expanded area (BFM #64 to #87,
#120 to #143, #176 to #239 and #304 to #367) to support CC-Link Ver. 2.00.
• In the 64CCL, only the expanded area is available when the expanded cyclic transmission is set to
"double", "quadruple" or "octuple".
• Either the area compatible with the FX
2N-32CCL (BFM #0 to #23) or expanded area is available when the
expanded cyclic transmission is set to "single".
• Several settings and statuses are added to the buffer memory area #24 to #31. For details, refer to the
following page and to Section 7.2.
