Classification Of Machine Input/Output Signals; Allocation Of Machine Input/Output Signals - Mitsubishi Electric MELDAS C6 Interface Manual

3.2 Classification of Machine Input/Output Signals

The signals handled by the PLC are classified as shown below.
Refer to the following table when making allocations during design.
Signal type
RIO-M
RI
RIO-M/S
EXT
DI

3.3 Allocation of Machine Input/Output Signals

The signals are allocated to the devices of machine input/output signals X and Y, and the device
Nos. are determined automatically depending on the connection destinations.
The connection destinations and allocated device Nos. are as below:
Destination Input device
RIO-M
RIO-M/S
X100~X1FF
EXT1
X200~X27F
EXT2
X280~X2FF
(Note 1)
EXT3
X300~X37F
(Note 1)
EXT4
X380~X3FF
DIO
X400~X40F
(Note 2)
CR05
(Note 1) Another unit for extension is necessary to use the expansion slot 3 and 4.
(Note 2) This is connected to the communication terminal.
(Note 3) The unused I/O can be used as input/output device of each type network. Furthermore,
the input/output devices of slot with the expansion cards (Ethernet cards, etc.) which do
not need the input/output devices is also unused, and that can be used.
