DPRAM buffer communication between CX CPU and PROFIBUS controller

Slave data volume limited by PROFIBUS frame size and configured addresses

Full 125-slave network support subject to bus speed and topology

Material Composition:​

Housing: industrial molded plastic fieldbus module case

D-sub connector: metal-shielded 9-pin PROFIBUS interface

PCB: multilayer FR4 with PC/104 interface contacts

Heat dissipation: passive convection without fan

Structural Characteristics:​

Compact CX fieldbus module for PC/104 stacking

Front 9-pin D-sub PROFIBUS port and status access

Side PC/104 interfaces for connection to CX CPU/power modules

Narrow 38 mm width for dense CX system stacks

Working Principle:​

The module connects to the CX CPU through the PC/104 ISA bus and DPRAM. TwinCAT configures slave parameters, addresses and cycle times. The PROFIBUS controller serializes cyclic and acyclic data over the D-sub interface, exchanges I/O with up to 125 slaves, and returns diagnostic information to the CPU.

Installation Requirements:​

Stack on a PC/104-compatible CX system with TwinCAT 2 support

Set PROFIBUS address, baud rate and topology before network startup

Use shielded PROFIBUS cable and proper bus termination at both ends

Install within an IP20 control cabinet with adequate spacing

Usage Precautions:​

Confirm all slaves use matching baud rate and bus polarity

Do not operate without proper 9.6 kbaud-12 Mbaud cable rating

Verify DPRAM address settings when combining multiple CX1500 modules

Replace or configure only with TwinCAT-supported driver and firmware versions
