Procedure

1)Turn off the power.

Disconnect all the cables connected to the PLC main unit and special adapter,

2)3)4)indicated.

5)Connect the special adapter (fig.C) to the main unit as shown on the

right.

6)Slide back the special adapter adapter (fig.C).

Connect all the high-speed I/O special adapters before connecting other special adapters when they are used in combination.

Do not connect a high-speed I/O special adapter on the left side of a communication or analog special adapter.

3.2Connection to the FX 3UC (D, DSS) Series PLC

Procedure

1)Turn off the power.

Disconnect all the cables connected to the PLC, and demount the PLC from the DIN rail.2)Remove the special adapter connector cover (fig.A).

3)Slide the special adapter slide lock (fig.B)of the main unit.

when connecting this product to another special adapter, please replace the 'main unit' in the above description with a 'special adapter' and perform the procedure as indicated.
