Local expansion features with signal modules
The XC600 can be expanded by the XI/ON signal modules.
The modules are fitted on the right beside the PLC on the top-hat
rail. The PLC behaves like a PROFIBUS DP gateway with a bus
refreshing module for the XI/ON modules. The gateway is
implemented with software. The base module assumes the task of
the bus refreshing module.
The maximum number of XI/ON modules depends on the I/O
design structure.
The following modules can be connected directly to the
XC-ADP-XION base module:
• Modules with tension spring connector
• Modules with screw terminals, without C rail
Bus refreshing modules and power feeding modules can not be
connected directly.
Assembly
The modules are supplied separately and must be fitted together.
Observe the order shown in figure1 and fit the base module first
of all on a horizontal mounting rail.
Fitting/removing modules
The back of the base module is provided with an eccentric disc.
Using a cheese head screwdriver, turn this disc so that it grips
underneath the mounting rail and secures the base module. The
front of the disc has number markings to ensure that it is
positioned correctly.
X
To fit the module onto the mounting rail, turn the eccentric disc
until the longer slot of the crosspoint slot points to the “1”
position (
a
fig. 3).
X
Hook the base module on the mounting rail (
a
fig. 3).
X
Turn the eccentric disc to the right until the base module is
secured firmly.
X
Plug on the power supply module, then the function module.
The operator module is the last component to be fitted
(
a
fig. 4).

h More detailed information concerning expansion issues
can be found in the “Hardware and Engineering”
manuals for:
• XI/ON PROFIBUS DP (AWB2700-1394)
• XI/ON CANopen (AWB2700-1395)
Caution!
Only remove or fit modules with the power supply
switched off. Discharge yourself from any electrostatic
charge before touching a module.
Voltage peaks on the bus connector may cause
malfunction or damage to the module.
h The modules are removed in the opposite sequence
(
a fig. 5 and 6).
