3.4 Connection with PLC
The 64CCL connects with an FX3U PLC via an extension cable.
The 64CCL is handled as a special extension block of the PLC. The unit number of the 64CCL is
automatically assigned No.0 to No.7 (Unit No.1 to No.7 is assigned when the main unit is an FX
3UC-32MT-
LT(-2).) starting from the special function unit/block closest to the PLC main unit. (This unit number is used for
the designation of a FROM/TO instruction.)
For details on the assignment of the I/O number and unit number of the PLC, refer to the following manual
corresponding to the connected PLC.
