Design
The XC600 PLC has a modular design. The basic unit consists of
the base module, power supply, CPU and operator modules, and
can be expanded by using function modules for communication.
Modules for the standard PROFIBUS-DP and CANopen networks
are therefore provided for this purpose. The modules provide the
controller with access to the I/O devices that log process signals
and control actuators.
The connections for the process signals can also be implemented
locally, using the input and output modules from the XI/ON series.
This requires the use of the power supply module with the
integrated interface and the base module with the adapter for the
XI/ON modules
a table 1.
A module consists of a circuit board that is fitted into a frame. The
special frame design makes it possible to stack the modules
together, thus allowing compact functional units to be combined
to suit the requirements of the task at hand.
The boards for the individual function modules meet the PC/104+
specifications. In addition to dimensions, the specifications also
stipulate the requirements for the PC/104+ bus that connects the
modules. This bus also carries the power supply voltages from the
power supply module to the individual function modules.
Differing base and supply modules are available. Your selection is
dependant on the type of I/O modules used.
Table 1: Possible module combinations
The power supply module generates the 5 V DC supply voltage for
the I/O module. The supply voltage as well as the data and address
bus are routed to the I/O modules via the base module. The
adapter on the base module provides the interface to I/O modules.
The 24 V DC field power supply of the XI/ON modules is also
connected to the XC-ADP-XION base modules.
