GE STXPNS001 RSTi ProfiNet Slave Network Adapter

The GE STXPNS001, also cataloged as the STXPNS001 RSTi ProfiNet Slave Network Adapter, operates as a dedicated hardware component for distributed I/O communication within PROFINET industrial Ethernet networks. The adapter functions as a PROFINET slave device, providing deterministic data exchange between RSTi slice I/O modules and supervisory PLC or PAC controllers through integrated Ethernet switching architecture.

Hardware Specifications

Profinet Deterministic Networks and I/O Density Scaling

The STXPNS001 serves as the communication gateway between a PROFINET controller and distributed RSTi I/O assemblies. Operating at 100 Mbps full-duplex Ethernet speed, the adapter exchanges cyclic process data while supporting deterministic network performance required for industrial automation applications.

The module supports expansion of up to 32 connected RSTi slice I/O modules, including the termination module. This architecture enables incremental I/O density scaling without modification of the network interface structure. Configuration is performed through standard PROFINET engineering environments using GSDML device descriptions.

Frequently Asked Questions

Q: How many RSTi modules can be connected to the STXPNS001?
A: The adapter supports up to 32 RSTi slice modules, including the required termination module.

Q: Does the adapter support MRP ring redundancy?
A: No. Available specifications indicate support for line and star topologies only and do not support MRP ring topology operation.

Q: What process data capacity is available?
A: The adapter supports up to 128 bytes of input data and 128 bytes of output data for cyclic PROFINET communication.

Field Installation Guidelines

• Mount the adapter securely on a compatible DIN rail before attaching expansion I/O modules.

• Install the termination module at the end of the slice I/O assembly.

• Verify the 24 VDC supply remains within the specified 11 VDC to 28.8 VDC operating range.

• Use industrial Ethernet cabling suitable for PROFINET communication environments.

• Configure the device using the appropriate GSDML file within the PLC engineering software.

• Maintain physical separation between Ethernet cabling and high-voltage power wiring.

• Verify network device naming and IP addressing before commissioning.

• Confirm correct I/O mapping and cyclic data exchange after startup.
