6ES7193-6AR00-0AA0 Siemens Bus Adapter

Pedido nº.: 6ES7193-6AR00-0AA0

Designation: SIMATIC ET200SP Bus Adapter BA 2×RJ45

Descrição: Dedicated bus adapter for ET200SP IM155-6 PN interface module, equipped with 2-channel RJ45 PROFINET ports.

⚠️ Common Misconception: It is NOT a BaseUnit. BaseUnits share the same 6ES7193 prefix but carry 6BPxx type codes. This unit is a communication bus adapter, plugged onto the rear of the IM155-6 interface module.

Compatible Interface Modules

Fits all IM 155-6 PN series interface modules:

6ES7155-6AU01-0BN0 IM155-6 PN ST

6ES7155-6AU00-0DN0 IM155-6 PN HS

6ES7155-6AA01-0BN0 IM155-6 PN HF

Aplicações Típicas

1. Line Daisy-Chain Connection: Porta 1 receives signal from PLC, Porta 2 cascades to the next ET200SP station.
2. PROFINET MRP Ring Network: Form closed redundant ring with dual-port devices at both ends.
3. Comparison with alternative ET200SP bus adapters

Seleção & Diretrizes de instalação

1. IM155-6 PN module must be fitted with a bus adapter; the bare module cannot accept network cables directly.
2. MRP redundant ring requires 6AR00 dual RJ45 version. Single-port 6AF00 cannot support ring topology.
3. It is recommended to use Siemens industrial green PROFINET cables and industrial shielded RJ45 plugs.
4. The module shall only be mounted on DIN35 rail inside control cabinets; outdoor installation is prohibited.

Common Troubleshooting Tips

Intermittent communication: Check shielding grounding of RJ45 connectors and ensure all 8 cable cores are terminated.

Failure to establish MRP ring: Confirm MRP is activated in TIA Portal and all ring nodes use dual-port bus adapters.

Distinction reminder: 6ES7193-6BPxx = IO module base unit, cannot be used for network connection.

Application Scenarios for 6ES7193-6AR00-0AA0 (BA 2×RJ45)

Core Feature: Dual RJ45 bus adapter dedicated to ET200SP IM155-6 PN with integrated two-port switch. Supports PROFINET daisy-chain wiring and MRP redundant ring, eliminating extra external switches and enabling multiple remote IO stations deployed sequentially along one cable route.

> Referência: Single-port 6AF00 is adopted for isolated end stations; 6AR00 is selected when cascading or ring redundancy is required.

1. Scenarios Classified by Network Topology (Most Widely Used in Engineering)

(1) Daisy-Chain Topology (Highest Consumption)

✅ Suitable Conditions: Equipment arranged linearly along production lines, orçamento limitado, no network redundancy requirement

Layout: PLC switch → ET200SP (Port1 IN, Port2 OUT) → next ET200SP → …

Vantagens: Greatly reduce cable routing between control cabinets; no additional industrial switches needed.

Desvantagens: All downstream stations will go offline if the middle link is broken.

Typical Sites:

Packaging lines, linhas transportadoras, roller lines, sorting lines

Linked machine tool production lines, máquinas para trabalhar madeira, plastic extrusion lines

Distributed IO along AGV guide tracks

Multi-cabinet connection for medium & small complete machines (main cabinet → multiple workstation sub-cabinets)

(2) MRP Media Redundant Ring (Preferred for High-Reliability Applications)

✅ Suitable Conditions: Unplanned production shutdown is unacceptable; automatic recovery upon single cable breakage

Layout: All ET200SP stations form a closed loop, MRP enabled in TIA Portal. Communication path switches automatically if one cable fails to maintain continuous production.

Typical Sites:

Automotive welding, coating and final assembly conveyor lines

Automated warehouses, stacker crane logistics systems

Continuous production lines in food & pharmaceutical industries

Estações de tratamento de esgoto, pump station group process control

(3) Hybrid Topology (Daisy-Chain + Star)

ET200SP stations along each production line are connected in daisy chain, and the terminal of each line is connected to the central switch. Balances convenient wiring and centralized management.

2. Industry-Specific Application Cases

🔹 Automotive Manufacturing (Aplicação mais comum)

1. Welding workshop: Distributed signal collection for body fixtures, welding guns and sensors; linear daisy-chain layout on long conveyors; MRP rings deployed at critical sections.
2. Coating lines: Remote IO deployed along electrophoresis, drying and conveyor chains.
3. Final assembly lines: IO for tightening tools, stoppers and photoelectric sensors arranged along assembly lines.

🔹 Logistics & Automação de Armazém

Automated stereoscopic warehouses, sorting conveyors, cross-belt sorters

Mass distributed workstation IO arranged along roller conveyors; MRP rings adopted on key logistics trunk lines to avoid full sorting line shutdown caused by cable faults.

🔹 Packaging, Borracha & Plástico, Máquinas de impressão (Mainstream for OEM Machine Builders)

Multi-unit complete equipment: Extrusoras, film blowing lines, filling lines, carton packaging lines

Equipment consists of main cabinet plus several independent workstation sub-cabinets connected via daisy chain to save wiring.

> OEM Selection Tip: Use 6AR00 for cascading multiple ET200SP inside one machine; adopt 6AF00 for the last end station to cut costs.

🔹 Food & Indústria Farmacêutica

Continuous processes including filling, sterilization and packaging; distributed control cabinets in clean areas.

MRP ring topology is generally recommended for continuous production to avoid material scrapping caused by network failures.

🔹 Water Treatment, Municipal Pump Stations & Environmental Projects

Aeration tanks, valve wells and chemical dosing systems in wastewater plants; pump stations distributed along pipelines.

Daisy-chain network for long-distance distributed IO; MRP redundancy enabled for critical processes.

🔹 Machine Tools & Processamento de metais

Flexible production lines, gantry robots, linked machine tools; peripheral IO for clamping, cooling and loading/unloading signal acquisition.

🔹 New Energy Industry

Battery PACK production lines, PV module assembly lines with massive distributed workstation IO.

3. Guia de seleção: When to Choose 6AR00 / Alternativas

✅ Prefer 6ES7193-6AR00-0AA0

1. ≥2 ET200SP stations on one link requiring cascading
2. PROFINET MRP redundant ring to be implemented
3. Espaço limitado no gabinete; no room for additional SCALANCE switches
4. Production lines arranged linearly with remote IO placed sequentially along conveyors

❌ Not Recommended (Choose 6ES7193-6AF00 Single RJ45 Instead)

1. The ET200SP is the last end station without further cascading
2. All stations connect to the switch via independent star cables, no daisy-chain layout
3. On-Site Installation Precautions
4. IP20 rating for indoor cabinet use only; fully enclosed protective cabinets are mandatory for outdoor or humid environments.
5. MRP ring requirement: All nodes in the ring must use dual-port 6AR00; single-port 6AF00 cannot be mixed in the ring.
6. Limit cascading quantity to ≤8~10 stations per daisy-chain link to avoid excessive communication latency.
7. For transmission distance over 100 m or heavy electromagnetic interference, switch to fiber adapter 6ES7193-6AG00-0AA0.
