2.2.6 External SIO Link of ROBONET
An example of implementing an external SIO
link using REXT extension units is shown to
the right.
In this example, the first stage and second
stage comprise a multi-stage layout, while the
last extension unit [3] in the second stage is
linked to a SCON or PCON-CF via SIO link.
(1) The units are installed on DIN rails.
(2) The multi-stage layout of the first stage
and second stage is the same as in 2.2.5.
Refer to 2.2.5.
(3) Connect each extension unit to an
adjacent unit using the power supply
connection plate and communication
connection circuit board supplied with
the extension unit.
(4) Place the extension unit for SIO link at
the end of the lowermost stream (bottom
stage) (extension unit [3]) and connect
the controller connection cable
(CB-REXT-CTL-) to the downstream unit
connector on the extension unit. Connect
the grounding wire with a M3 round
terminal to the FG terminal block.
(5) Connect the e-CON connector end of the
controller connection cable to a 4-way
junction.
(6) Connect the SCON or PCON-CF and
4-way junction using an optional
controller link cable (CB-RCB-CTL002).
The controller link cable
CB-RCB-CTL002 comes with the
following accessories. Use them to make
the connection as shown to the right:
x 4-way junction
(5-1473574-4 by AMP) x 1
x e-CON connector
(4-1473562-4) x 1
x Terminal resistor 220 :
(with e-CON connector) x 1
The customer must fabricate a junction
interconnection cable using the above
e-CON connector supplied with the
controller link cable.
Connect the ERC2-SE and 4-way
junction using the power-supply & I/O
cable (CB-ERC2-PWBIO) and network
connection cable (CB-ERC2-CTL001)
supplied with the ERC2-SE.
