Electronic Amplifier 6ES7972-0AB01-0XA0 For Online Diagnostics And Maintenance In Industrial Automation Compact Design

Key Features:

• Diagnostic Functions:
  • Topology Detection: Automatically determines the physical layout of the PROFIBUS network, including node addresses and distances, and stores this data in a topology table.
  • Fault Location: During operation, it continuously monitors the bus and can pinpoint the location and type of faults (e.g., cable breaks, short circuits) relative to known nodes.
  • Time Stamping: Equipped with an internal clock that timestamps diagnostic events, statistics, and topology data for accurate logging.
• Communication & Performance:
  • Transmission Rate: Supports 9.6 kbit/s to 12 Mbit/s, with automatic baud rate detection.
  • Network Expansion: Allows up to 31 nodes per segment, and supports three PROFIBUS segments (DP1, DP2, DP3), enabling connection of up to 62 nodes per repeater.
• Design & Installation:
  • Connection Type: Uses FastConnect insulation displacement technology for quick and reliable PROFIBUS cable connections.
  • Power Supply: Operates on 24 V DC (20.4 V to 28.8 V range).
  • Protection Class: IP20.
  • Dimensions: 80 mm (W) × 125 mm (H) × 67.5 mm (D).
  • Weight: Approx. 300 g.
• Environmental Tolerance:
  • Operating Temperature: 0°C to +60°C.
  • Storage/Transport Temperature: -40°C to +70°C.
  • Relative Humidity: Up to 95% at 25°C.
• Software Integration:
  • Compatible with STEP 7 V5.1 + SP2 or higher.
  • Supports SFC 103 “DP_TOPOL” for topology determination in S7 CPUs.
  • Firmware updates are possible via PROFIBUS using STEP 7 V5.2 or later.

Applications:

• Large or complex PROFIBUS networks where fault detection and network health monitoring are critical.
• Systems requiring high availability, as it enables proactive maintenance and rapid fault resolution.
• Retrofit and modernization projects, where existing PROFIBUS infrastructure needs enhanced diagnostics without full replacement.
