The Ultimate PROFIBUS DP Master for S7-300 in 2025

Still the most installed DP master module worldwide when you need to connect ET 200 stations, drives, valves, or third-party DP slaves to an S7-300 CPU. Plants keep it in stock because:

• Full DP-V1 acyclic services (read/write data records, alarms, diagnostics)
• Direct support for PROFIdrive, PROFIsafe, and iSlave modes
• Sync/Freeze, constant bus cycle, and redundancy capable
• Full TIA Portal 18 and STEP 7 V5.7 support (including F-CPUs)

Failure Symptoms Triggering Immediate Replacement

Network engineers order this exact card when:

• “CP 342-5 fault LED red” or all DP slaves go offline
• Diagnostic buffer “bus error / short-circuit” or “master timeout”
• CPU goes to STOP with OB86 rack failure after hot-swap
• New DP-V1 slaves no longer respond to acyclic services

Real-World Deployments 2024–2025

• Automotive: VW & BMW body shops – 120+ ET 200S stations per line
• Water Treatment: Siemens SITRANS – PROFIBUS DP valve islands & flow meters
• Process Industry: Distributed motor control centers with PROFIdrive VFDs
