CX2500-B310 | Fieldbus slave module PROFIBUS for CX20xx, CX52x0, CX53x0, CX56x0

The CX2500-Bxxx fieldbus slave modules are left-hand attachments for the CX20xx, CX52x0, CX53x0, and CX56x0 embedded PC series. The use of systems with fieldbus slave modules allows the CX system to be used as a subordinate local controller to build complex or modular systems. External process data is received from the main controller and processed, or data from its own process peripherals is returned directly or processed to the main controller.

The CX2500-B310 fieldbus slave module takes over the function of the  PROFIBUS slave  . Each module occupies one PCI Express lane so that a total of four of these modules can be connected in any desired combination to the left side of the CX20xx group. Fieldbus slave modules are single-channel modules. The CX2500-B310 fieldbus slave module for PROFIBUS can present itself to the host as multiple virtual slave stations (up to four times), resulting in a fourfold increase in the amount of process data exchanged .

Parallel operation of several identical or different slaves is possible, for example two PROFIBUS slaves or one PROFIBUS slave and one CANopen slave. In case of mixed operation between primary and secondary connections, CX systems act as smart gateways between different fieldbuses: data is received, processed and fed into other fieldbuses.

The primary or secondary connections network several CX systems together in a fully deterministic manner through the fieldbus level. CX fieldbus modules can be retrofitted/exchanged by adding them to existing CX systems. Scanning and identification of modules, parameterization, configuration of  connected I/O components, and online diagnostics of process/fieldbus status take place in TwinCAT  System Manager
