ROSOFT PLX51-PBS

1. Overview

2. Specifications

• Operating Mode: Functions as a PROFIBUS DP Slave, supporting simulation of 1 to 10 slave nodes (Ident Numbers), or as a single independent slave.
• Data Transfer: Up to 1536 bytes of input/output (I/O) data, a common capacity for PROFIBUS‑to‑EtherNet/IP communication.
• Communication Speed: Supports PROFIBUS DPV0 / DPV1 protocols with various baud rates (e.g., 1.5 Mbps, 12 Mbps).
• Power Supply: 10–36V DC, power consumption approximately 2.04W (at 24V).
• Dimensions: Standard DIN‑rail size (approx. 5.86 x 1.33 x 4.56 inches).
• Temperature Range: -20°C to +70°C.

6. Installation and Maintenance

• Mounting: Standard DIN‑rail installation for industrial cabinets or field enclosures.
• Configuration Tool: Setup and diagnostics via the PLX50 Config Utility, allowing users to configure module settings, connect to Rockwell Automation controllers, and create custom AOIs.
• Safety Note: The device has an Open Type design and must be installed in a suitable enclosure to meet industrial protection requirements (e.g., Class I hazardous or non‑hazardous locations).
• Diagnostics: Built‑in PROFIBUS packet capture tool helps reduce troubleshooting time during commissioning and maintenance.
