SCHIELE 2.423.422.00 – Profibus DP Communication Module | SCHIELE Automation Platform
Engineering Background
SCHIELE Systemtechnik has long been a trusted name in European industrial automation, delivering robust control and communication hardware for demanding process and discrete manufacturing environments. The Profibus DP (Decentralized Periphery) protocol remains the backbone of countless installed automation systems worldwide, enabling deterministic, high-speed communication between PLCs, drives, I/O nodes, and field instruments.
Product Positioning
The SCHIELE 2.423.422.00 is a dedicated Profibus DP slave/master communication module engineered for integration into SCHIELE modular control platforms. It provides a reliable, standards-compliant DP interface that bridges the controller backplane to the Profibus DP fieldbus segment — enabling seamless data exchange with distributed I/O, variable-speed drives, sensors, and actuators in real-time industrial networks. This module is the preferred choice for maintenance engineers sourcing certified replacement units and for system integrators expanding existing SCHIELE-based architectures.

Engineering Advantages
- Protocol Compliance: Full conformance to EN 50170 / IEC 61158 Profibus DP standard ensures interoperability with third-party masters and slaves.
- Auto Baud-Rate Detection: Eliminates manual speed configuration; module synchronizes automatically to the active segment baud rate.
- Hot-Swap Ready: Designed for modular rack architecture — reduces planned maintenance windows.
- Compact Form Factor: Single-slot module minimizes rack space consumption in space-constrained control cabinets.
- Diagnostic Support: Provides standard Profibus DP diagnostic bytes for rapid fault isolation via the engineering tool or SCADA system.
- Long Service Life: Industrial-grade components rated for continuous 24/7 operation in harsh environments.
System Architecture & Signal Flow
The 2.423.422.00 module seats into the SCHIELE modular rack and communicates with the CPU module via the proprietary backplane bus. On the field side, the DB9 connector interfaces directly to the Profibus DP segment cable (shielded twisted pair, IEC 61158-2). The module handles all DP protocol layers — physical, data link (FDL), and DP application — autonomously, offloading communication overhead from the main CPU. Configuration is performed via the GSD (General Station Description) file loaded into the Profibus master configuration tool (e.g., Siemens STEP 7, TIA Portal, or equivalent).
Typical Signal Flow: Field Device ↔ Profibus DP Segment ↔ 2.423.422.00 Module ↔ SCHIELE Backplane Bus ↔ CPU Module ↔ Application Program

Technical FAQ
Q: Is the 2.423.422.00 compatible with Profibus PA?
A: No. This module is designed for Profibus DP (RS-485 physical layer). Profibus PA requires a separate DP/PA coupler or link device.
Q: Can this module operate as a Profibus DP master?
A: The module’s master/slave capability depends on the SCHIELE CPU firmware and system configuration. Contact us with your CPU part number for confirmation.
Q: Where can I obtain the GSD file?
A: GSD files for SCHIELE Profibus modules are available from the SCHIELE Systemtechnik website or upon request from our technical support team.
Q: What is the maximum cable length for the Profibus DP segment?
A: At 12 Mbps, maximum segment length is 100 m. At 1.5 Mbps, up to 200 m. At 93.75 kbps, up to 1200 m (per EN 50170 specification).
Q: Do you offer a warranty?
A: Yes. All units carry a 90-day functional warranty. Extended warranty options are available — contact us for details.
