Schneider Electric TSXPBY100 | Modicon Premium PROFIBUS DP Kit

Product Introduction (Anti-Template)

A legacy Premium PLC installation can remain fully serviceable while its fieldbus interface becomes difficult to replace. The Schneider Electric TSXPBY100 is a PROFIBUS DP V0 communication kit designed for Modicon Premium and Atrium PLC systems. It provides the host interface, PCMCIA communication card, and T-junction connection required for integrating PROFIBUS DP networks with the PLC architecture.

The kit is intended for master communication rather than direct sensor or actuator wiring. It supports PROFIBUS DP data exchange, slave diagnostics, startup parameter handling, and configuration checks. For procurement, the complete kit composition matters: sourcing only the PCMCIA card or only the host module may leave the installation incomplete.

Key Technical Specifications

The official product description identifies TSXPBY100 as a V0 PROFIBUS DP module kit with a host module, PCMCIA card, and T-junction box. Schneider Electric also documents support for up to 126 slave devices and a maximum distance of 1,200 m at 9.6 kbit/s without a repeater.

Field Application & Technical Pitfalls (The Engineer’s Guide)

Premium PLC and Distributed I/O

TSXPBY100 is used to connect a Modicon Premium or Atrium PLC to a PROFIBUS DP network. Typical applications include distributed I/O stations, remote control cabinets, motor-control equipment, and field devices that exchange process data through PROFIBUS DP.

Class 1 and Class 2 Master Communication

The kit supports Class 1 master functions for cyclic I/O data exchange and diagnostic handling. Class 2 functions support selected network management and diagnostic operations. PROFIBUS FMS messaging is not supported, so the required communication service should be checked before replacement.

Legacy System Maintenance

The TSXPBY100 is now a legacy reference. Schneider Electric lists it as discontinued and indicates that no direct replacement is assigned. Service availability varies by region, with some official records listing an end-of-service date of December 31, 2026.

Pitfall 1 — Ordering only one kit component:
TSXPBY100 is not simply one PCMCIA card. The complete kit includes the host module, communication card, and T-junction box. Confirm whether the customer needs the complete kit or only one replacement component.

Pitfall 2 — Confusing PROFIBUS DP V0 with DP-V1:
The is specified for PROFIBUS DP V0. Do not promise DP-V1 functions, acyclic services, or FMS messaging without confirming the actual PLC and communication requirements.

Pitfall 3 — Incorrect cable length or baud-rate assumptions:
The maximum network distance depends on the transmission rate, cable construction, and repeater arrangement. At 12 Mbit/s, the documented distance is 100 m without a repeater; at 9.6 kbit/s, it can reach 1,200 m without a repeater. A network that worked at a lower baud rate may become unstable after a speed change.

A maintenance team may replace a failed PCMCIA card and still see intermittent bus faults because the T-junction, shield termination, or host module has also degraded. The practical lesson is to test the complete communication path—not just the visible card—before returning the PLC network to service.

Quality Control (QC) SOP & Transparency

1. Complete Kit Identification
   Verify the marking and check whether the package includes the TSXPBY10 host module, 467NHP81100 PCMCIA card, and 490NAE91100 T-junction box.
2. Physical Inspection
   Inspect the host module, PCMCIA card, cable, connectors, and T-junction box for corrosion, cracks, bent contacts, damaged locking parts, or missing hardware.
3. Part-Number Verification
   Compare every component number with the customer’s existing installation. A complete kit should not be represented by a single card number.
4. Host-System Compatibility Check
   Confirm that the customer’s PLC is a compatible Modicon Premium or Atrium system and verify the processor and rack arrangement.
5. Communication Interface Inspection
   Check the RS-485 interface, integrated cable, PCMCIA connector, and T-junction connection for physical damage or abnormal wear.
6. Network Test
   Where a suitable test setup is available, verify master startup, slave detection, cyclic data exchange, and diagnostic communication.
7. Parameter and Configuration Review
   Confirm the intended baud rate, slave count, network topology, GSD configuration, and required master functions before shipment.
8. Final QA and Packaging
   Photograph the identification labels and kit contents. Protect the PCMCIA card and connectors against ESD, impact, moisture, and contamination during transportation.

FAQ

Q1. What is Schneider Electric used for?
It is a PROFIBUS DP V0 communication kit for Modicon Premium and Atrium PLC systems. It allows the PLC to operate as a PROFIBUS DP master.

Q2. What components are included in the kit?
The documented kit consists of the TSXPBY10 host module, 467NHP81100 PROFIBUS DP PCMCIA card, and 490NAE91100 T-junction box.

Q3. How many PROFIBUS DP slaves can it support?
The documented maximum is 126 slave devices. The practical number may be lower depending on the PLC application, network design, diagnostic requirements, and available process memory.

Q4. Does support PROFIBUS DP-V1?
The product is specified as a PROFIBUS DP V0 kit. DP-V1 functions should not be assumed without confirming the complete PLC hardware, firmware, and communication configuration.

Q5. What is the maximum communication distance?
The documented distance is 1,200 m at 9.6 kbit/s without a repeater. At 12 Mbit/s, the stated distance is 100 m without a repeater.

Q6. Can the PCMCIA card be replaced separately?
The PCMCIA card is a component of the kit and may be sourced separately if the customer’s requirement is limited to that component. Confirm the exact card number and cable arrangement before ordering.

Q7. Is discontinued?
Yes. Schneider Electric lists the reference as discontinued and states that it has no assigned direct replacement. Some regional product records list service availability through December 31, 2026.

Q8. What information should be provided for an accurate quotation?
Provide the reference, the PLC processor model, a photo of the existing kit, the required PROFIBUS baud rate, the number of slave devices, and whether the customer needs the complete kit or only the host module, PCMCIA card, cable, or T-junction box.
