PROFINET Features

• Supports protocol conversion between PROFINET and Modbus serial.
• Compliant with standard PROFINET RT and IRT protocols.
• Supports PROFINET MRP (Media Redundancy Protocol) for ring network redundancy and SR System Redundancy (S2).
• Supports up to 32 slots; input/output byte lengths can be configured via TIA Portal or STEP7.
• Serial ports support both Modbus protocol and user-defined universal serial protocols.
• Dual 10/100 Mbps auto-negotiating Ethernet ports with an integrated switch, ideal for daisy-chain topologies.
