5.1 FP0 I/O Link Unit (MEWNET–F)
The FP0 I/O Link Unit (MEWNET–F) works as the slave station of a Remote I/O System.
The FP0 I/O Link Unit exchanges I/O information with the Master Unit. Use a
two–conductor cable to connect the master unit and the FP0 I/O Link Unit. To connect
the FP0 I/O Link Unit to the FP0 Control Unit or FP0 Expansion Unit, use the expansion
connector. The FP0 I/O Link Unit functions as a buffer. The output from the master unit
is sent to the input of the FP0 through the FP0 I/O Link Unit. The output from the FP0
is sent to the input of the master unit from the FP0 I/O Link Unit. Be sure to connect the
FP0 I/O Link Unit with a master unit. Without a master station, the slave station
(including FP0 I/O Link Unit) will not work.
