Technical Parameters
Core Advantages
1. Seamless PROFIBUS-DP Slave Integration
The -8MD01 variant is specifically engineered for distributed automation architectures. Its built-in SINEC L2-DP slave interface allows the S5-95U to be configured as a PROFIBUS-DP slave under a master controller (such as an S7-300/400, a PC with CP5613, or another S5-95U acting as master) . This makes it ideal for expanding existing PROFIBUS networks with compact, self-contained control nodes that handle local I/O while reporting back to the central master.
2. Comprehensive Onboard I/O in a Compact Package
The 6ES5095-8MD01 provides a versatile I/O mix directly on the CPU: 16 digital inputs (including 4 alarm and 2 counter inputs), 16 digital outputs (0.5A sourcing), 8 analog inputs, and 1 analog output . This onboard capability handles many local control tasks without requiring additional expansion modules, reducing system cost and complexity.
3. Expandable for Larger Applications
Despite its compact size, the S5-95U can be expanded with up to 32 peripheral modules from the S5-100U series, including digital I/O, analog I/O, and special function modules . This scalability makes it suitable for a wide range of application sizes, from simple standalone control to more complex distributed systems.
4. Proven Legacy Platform with Established Integration Paths
The S5-95U with DP slave interface has a well-documented integration path with modern systems. Engineers have successfully integrated the 6ES5095-8MD01 as a DP slave in STEP 7 projects using a GSD file, enabling communication with modern PROFIBUS masters like the CM 1542-5 . This allows legacy S5 equipment to remain productive within modern automation architectures.
5. Critical for Legacy System Maintenance
Many industrial facilities still rely on S5-95U compact controllers in production-critical applications. The 6ES5095-8MD01 is an essential spare for maintaining these systems, allowing operators to replace failed units without undertaking a complete system migration .

Frequently Asked Questions (FAQ)
Q1: What is the Siemens 6ES5095-8MD01?
It is a compact central processing unit from the SIMATIC S5-95U series, featuring a built-in PROFIBUS-DP Slave interface for integration into distributed automation networks .
Q2: What distinguishes the -8MD01 from other S5-95U variants?
The -8MD01 is the PROFIBUS-DP Slave variant. It provides one PG interface (TTY, 20mA) and one PROFIBUS-DP slave port. Other variants offer dual AS511 ports (MC), FDL capability (MB), or DP master functionality (MD11) .
Q3: What I/O does this module provide?
It provides 16 digital inputs (24V DC, including 4 alarm and 2 counter inputs), 16 digital outputs (24V DC, 0.5A each), 8 analog inputs (0–10V), and 1 analog output .
Q4: How much program memory does the 6ES5095-8MD01 have?
It has 16 KB of user memory (RAM), equivalent to approximately 8,000 instructions .
Q5: Can I use this module as a PROFIBUS-DP master?
No. The -8MD01 is a DP Slave only. For DP master functionality, the 6ES5095-8MD11 is required .
Q6: How do I integrate the 6ES5095-8MD01 into a modern STEP 7 project?
The S5-95U DP slave can be integrated into STEP 7 using a GSD file. The document describes connecting it to a PROFIBUS master such as a CP 342-5 or CM 1542-5. Parameters are set in STEP 5 on the S5-95U side, and the GSD file is used on the master side .
Q7: Is this a genuine Siemens product?
Yes. This is a genuine Siemens module. Depending on availability, units may be new original or professionally refurbished .
Q8: Is the SIMATIC S5 series still in production?
No. The SIMATIC S5 series has been discontinued by Siemens and replaced by the S7 series. The S5-95U is available only through third-party suppliers and remaining stock .
Q9: What is the modern replacement for the S5-95U?
The closest functional equivalent is the S7-1200 (CPU 1214C for compact applications) or S7-1500 (CPU 1511 for higher performance). However, STEP 5 programs do not auto-convert — migration requires manual porting.
Q10: What should I verify before ordering?
Always verify the exact part number (6ES5095-8MD01), confirm your system requirements (DP slave functionality), and check whether your application requires expansion modules or specific firmware features .
