The CX2500-Bxxx fieldbus slave modules are left-sided attachments

for the Embedded PC series CX20xx, CX52x0. CX53x0 and CX56x0.

The use of systems with fieldbus slave modules enables the use of

a CX system as a subordinate local controller for the construction of

complex or modular systems. External process data are received from

the master and processed, or data from its own process peripherals

are returned to the master controller directly or processed.

The CX2500-B310 fieldbus slave module assumes the function of a

PROFIBUS slave. Each module occupies a PCI Express® lane, so that

a total of four of these modules can be connected in any desired

combination to the left side of a CX20xx group. The fieldbus slave

modules are single-channel modules. The CX2500-B310 fieldbus slave

module for PROFIBUS can present itself to the master as a multiple

(max. quadruple) virtual slave station, resulting in a four-fold increase

in the quantity of exchanged process data.

The parallel operation of several identical or different slaves is possible,

e.g. two PROFIBUS slaves or a PROFIBUS slave and a CANopen slave.

In the case of mixed operation of master and slave connections, CX

systems act as intelligent gateways between different fieldbuses: data

are received, processed and fed into other fieldbuses.

Master or slave connections network several CX systems with one another

strictly deterministically via the fieldbus level. CX fieldbus modules can be

retrofitted/exchanged by adding them to existing CX systems.

The scanning and recognizing of the modules, the parameterization, the

configuration of the connected I/O components and the online diagnostics

of the process/fieldbus status take place in the TwinCAT System Manager.
