Working Principle:
The 5205-DFNT-PDPS contains two independent communication ASICs — one for DeviceNet and one for PROFIBUS DP. The DeviceNet ASIC operates as a slave node, responding to poll requests from the DeviceNet master (typically an Allen-Bradley ControlLogix or CompactLogix PLC). Simultaneously, the PROFIBUS DP ASIC operates as a slave station, responding to cyclic I/O read/write requests from the PROFIBUS DP master (typically a Siemens S7-300/400 PLC). The module’s internal dual-port RAM buffer stores incoming data from one network and makes it available to the other network on the next poll cycle. Data mapping is pre-configured at the factory for 16 words input / 16 words output by default, with full remapping possible via the GSD/EDS file in the respective engineering tools. The module draws its 5V operating power from the PROFIBUS DP bus and receives 24VDC power from the DeviceNet trunk cable, making it fully bus-powered on both sides.

Key Advantages:

• Eliminates Protocol Barriers: Enables Rockwell and Siemens PLCs to communicate directly without a third-party protocol converter at the PLC level.
• Zero Programming Overhead: DIP switch configuration eliminates the need for gateway configuration software.
• Dual Certification: ODVA DeviceNet certified and Siemens PROFIBUS DP compatible via GSD file.
• Compact DIN Rail Form Factor: Saves panel space compared to rack-mounted protocol converters.
• Low Latency: Typical data exchange latency is < 10 ms end-to-end.
• Fail-Safe Behavior: If either network loses communication, the module stops updating data on the other network, preventing stale data propagation.

Applicable Industries:

• Automotive Manufacturing: Bridging Allen-Bradley DeviceNet sensors with Siemens PROFIBUS DP PLCs on mixed-vendor assembly lines
• Food & Beverage Processing: Integrating Rockwell packaging machines with Siemens batch control systems
• Oil & Gas: Connecting DeviceNet field instruments to Siemens DCS/PLC platforms
• Pharmaceutical Manufacturing: Linking Rockwell batch controllers with Siemens MES systems
• Water/Wastewater Treatment: Integrating DeviceNet SCADA devices with Siemens PROFIBUS DP RTU networks
• Material Handling: Connecting Allen-Bradley VFDs and sensors to Siemens conveyor control systems

Model Series:
The 5205-DFNT-PDPS is part of the ProSoft 5200 Series of gateway modules. Related models include:

All 5200 series modules share the same DIN rail form factor and DIP switch configuration method.

Installation Requirements:

• DIN Rail Mounting: Snap the module onto a 35 mm DIN rail (TS 35 / EN 60715 compliant). Ensure the rail is firmly secured to the panel.
• DeviceNet Wiring: Connect the 5-pin M12 cable to the DeviceNet trunk or drop line. Pin assignments: Pin 1 = 24VDC, Pin 2 = GND, Pin 3 = CAN-H, Pin 4 = CAN-L, Pin 5 = Shield/Drain.
• PROFIBUS Wiring: Connect the DB-9 cable to the PROFIBUS DP network. Pin assignments: Pin 3 = RxD, Pin 8 = TxD, Pin 1 = Shield/Drain.
• Termination: Install 120 Ω termination resistors at both ends of the PROFIBUS DP network. The 5205-DFNT-PDPS does not include built-in termination — external termination is mandatory.
• DeviceNet Termination: Install 121 Ω termination resistors at both ends of the DeviceNet trunk. The module includes an internal 121 Ω termination that can be enabled via DIP switch position 8.
• Power Isolation: Ensure the 24VDC DeviceNet power supply is isolated from the PROFIBUS DP network ground to prevent ground loops.
• Cable Length: Maximum DeviceNet cable length is 500 meters at 125 kbps. Maximum PROFIBUS DP cable length is 1200 meters at 1.5 Mbps (with repeaters).

Usage Precautions:

• Do not connect or disconnect cables while power is applied to either network — this will cause communication errors and may corrupt the module’s non-volatile configuration.
• Do not exceed the maximum node address of 63 on DeviceNet — addresses above 63 are reserved and will cause bus errors.
• Do not exceed the maximum station address of 126 on PROFIBUS DP — address 0 is reserved for the DP master.
• Verify DIP switch settings match the network configuration before powering up. Mismatched baud rates will prevent communication on that network.
• Do not install in locations with direct exposure to water, oil mist, or corrosive chemicals — the module is rated IP20 only.
• Do not apply more than 30 VDC to the DeviceNet power input — this will damage the onboard voltage regulator.
• Clean M12 and DB-9 connectors with isopropyl alcohol (≥ 99%) before initial connection.
• Replace the module if any LED indicates a persistent fault condition — the module does not support field repair.
• Update GSD/EDS files from the ProSoft website before commissioning to ensure compatibility with the latest firmware version.
