Product Overview; Cx1500-M510 (Master) - Beckhoff CX1500-M510 Manual

Product overview

2 Product overview
The connection to the Profibus for the CX-family is realized by field assembles modules. There are two
versions of modules:
• Master connection [} 8]
• Slave connection [} 10]
The function is similar to the function of the Beckhoff PCI fieldbus cards. In opposite to them only one port is
available in the modules for CX-Systems. The connection parameters will be set by using TwinCAT. The
data transfer to the system is realized by a DPRAM via PC104 bus.
2.1

CX1500-M510 (Master)

Fieldbus connection enable the distributed collection of process data and signals, even for distant machines
or equipment. The use of fieldbus master modules in a CX10x0 system enables the
utilization of all Beckhoff fieldbus components (e. g. Bus Coupler, Bus Terminal Controller, drive technology)
as distributed control components for the assembly of complex systems.
Parallel operation of several identical or different master connections is also possible, Mixed operation of
master and slave connections is also not a problem. A CX system can thus also assume the functionality of
an intelligent gateway between different fieldbuses, receiving data from a fieldbus, processing them via a
program and then feeding them into another fieldbus.
The performance data of the CX fieldbus master modules are nearly identical to those of the Beckhoff PC
fieldbus cards, except for the fact that the CX variants are always single-channel types. The number of
slaves that can be connected is only limited by the respective bus system. The use of master or slave
connections enables networking of several CX systems with each other via the fieldbus level. In contrast to
networking via Ethernet, strictly deterministic data transmission can be achieved in this case.
CX fieldbus modules can be upgraded or exchanged in the field and can be connected to an existing CX
system via the PC104 system bus. The power supply of the fieldbus connections is also ensured via the
PC104 bus. Despite the ISA bus, no address switch is required for the address setting, since the modules
are assigned an address via internal setup. (The address must be selected by ordering the module)
The software integration of the fieldbus connections into the TwinCAT automation software is done in the
usual comfortable way: Scanning and detection of the modules, parameterization, configuration of the
connected I/O components as well as online diagnosis of the process and fieldbus status are carried out in
the familiar way through the TwinCAT System Manager.
