Schneider 467NHP811-DP Modicon Profibus DP Communication Module

Configured for distributed field device communication in Modicon Quantum and Premium networks, the Schneider 467NHP811-DP (467NHP811-DP Profibus DP Network Interface Module) provides direct physical/electrical execution. The hardware operates as a dedicated PCMCIA card engineered to fit directly into host communication modules, including the Modicon Quantum 140CRP81100 or Premium TSXPBY100 master controllers. The module serializes backplane data registers into differential RS485 signaling variables matching the cyclic framing rules defined by the IEC 61158 Profibus standard.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The Schneider 467NHP811-DP utilizes a specialized co-processing engine that runs independently of the main controller's central processing updates. This independence prevents varying network turnaround constraints from interrupting parameters governed under backplane bus communication velocity licenses. Transmission rates scale mathematically up to 12 Mbps, ensuring deterministic data exchange for remote peripheral drops.

When bridging legacy fieldbuses over modern industrial architectures, such as Profinet / EtherNet/IP deterministic networks, this PCMCIA card functions as an isolated protocol anchor. The hardware layer accommodates dense I/O density scaling profiles up to 125 field nodes, ensuring that multi-byte variable blocks are cyclically transferred to the local rack memory maps within sub-millisecond network schedules.

Frequently Asked Questions

Q: Can the 467NHP811-DP card be extracted or hot-swapped from the host 140CRP81100 module under active backplane power?

A: No. The internal contact tracks of the PCMCIA connection system lack the specialized grounding offsets needed for live extraction. Removing or inserting the card while power is applied can cause transient current surges, risking permanent physical component failure or halting the master rack backplane.

Q: How is the specific network transmission rate configured on the 467NHP811-DP card assembly?

A: The module does not feature manual hardware switches for speed selection. The transmission rate (ranging from 9.6 kbps up to 12 Mbps) is defined in the network master configuration utility within the programming software environment and downloaded directly to the module memory.

Q: What physical adapter is required to connect standard DB9 Profibus cables to this card?

A: The 467NHP811-DP requires a matching external connection accessory, such as the 490NAE91100 bus adapter. This adapter routes the internal PCMCIA interface ribbon out to a standard standard DB9 connector port.

Field Installation Guidelines

• Shut down the primary power supply feeds to the controller chassis before attempting to insert or remove the PCMCIA communication card.
• Guide the card into the designated communication slot of the master interface module, applying steady pressure until the card is fully seated against the internal connector pins.
• Attach the required 490NAE91100 network interface adapter cable to the external port of the card and secure the structural lock mechanisms.
• Verify that the terminal nodes on the physical Profibus DP network segment have active termination resistors switched ON to prevent signal reflections.
• Maintain at least 30 cm of space between the network cabling and adjacent high-current AC circuits or drive conductors to suppress electromagnetic signal distortion.
