7.9.1 Wiring the Input Side DI Connector (CG31/CG33)
The DI connector on the input side of the operation panel I/O unit is wired in the same manner as the
M60/M600 Series base I/O unit (FCU6-DX Series) and remote I/O unit (FCUA-DX Series).
Refer to the section "7.9.3 Outline of Digital Signal Input Circuit".
7.9.2 Wiring the Output Side DO Connector (CG32/CG34)
An insulation type DO output is used with the operation panel I/O unit. (Effective in improving the resistance
against noise from external sources)
So, the DO output power is supplied from an external source, and the wiring method on the machine side
differs from that of M60/M600 Series I/O unit (FCU6-DX Series, FCUA-DX Series).
Refer to the section "7.9.4 Outline of Digital Signal Output Circuit".
The wiring also differs for the sink type (FCU7-DX670/DX770) and source type (FCU7-DX671/DX771) DO
output. Refer to the section "7.9.5 Wiring for Sink Type Output" and "7.9.6 Wiring for Source Type Output" for
details on the wiring methods.
