8.2 Connecting with Remote I/O Unit
This chapter describes the connection of the remote I/O unit and machine control signals.
8.2.1 Outline of Remote I/O Unit
The following eight types of signals can be input/output from the remote I/O unit (FCUA-DX
) according to
the type and No. of contacts. Use serial link connections (MC link B) to connect the unit with the control unit or
the operation panel I/O unit.
When the remote I/O unit is connected with serial links, multiple units can be used as long as the total No. of
occupied stations (channels) is within 8 channels.
