Schneider STBNIP2311 Advantys STB Network Module

Schneider STBNIP2311 Advantys STB Network Interface Module

Product Introduction

The STBNIP2311 serves as the gateway for Schneider Electric Advantys STB distributed I/O islands. Specifically, this standard network interface module connects field devices to an Ethernet Modbus TCP/IP network. It represents the island as a single node, enabling efficient data exchange with PLCs and SCADA systems.

This dual-port design offers significant advantages. For instance, it supports daisy chain topologies and provides redundant network paths. Furthermore, an embedded web server allows for remote configuration and diagnostics. The module also features a removable memory card slot for storing configuration data.

Communication and Protocol Support

The STBNIP2311 module provides robust communication capabilities. It features two RJ45 ports with auto MDIX functionality. Additionally, it supports 10/100 Mbit/s transmission rates in half or full duplex modes. The module communicates using the Ethernet Modbus TCP/IP protocol, conforming to IEEE 802.3 standards.

Besides Modbus TCP/IP messaging, the NIM offers several communication services. These include an SNMP agent, BootP/DHCP protocol support, and HTTP services. Meanwhile, the integrated web server facilitates configuration and access to island variables. This network interface module can address up to 32 I/O modules across one primary segment and six extension segments.

Electrical Specifications and Power

Power requirements for the STBNIP2311 are straightforward. It operates on a 24V DC supply voltage with SELV isolation. Input current for the supply circuit is 550 mA. Moreover, the module delivers a logic bus output of 5.25V DC with a tight tolerance of ±0.21%.

The nominal output current reaches 1.2 A. However, derating applies at higher temperatures. Specifically, the output current drops to 0.575 A when operating between 60°C and 70°C. The module includes seven local LEDs for status monitoring. These indicators cover ACT, RUN, ERR, MS, NS, PWR, and TEST functions.

Mechanical and Environmental Parameters

The STBNIP2311 features a compact form factor for space-constrained installations. Its dimensions measure 40.5 mm in height, 130 mm in width, and 70 mm in depth. The module weighs approximately 0.145 kg. It mounts easily on a standard 35 mm DIN rail.

Environmental specifications ensure reliable operation. The protection rating is IP20, suitable for clean industrial environments. Operating temperature ranges from 0°C to 60°C without derating. Furthermore, storage temperature ranges from -40°C to 85°C. The module withstands vibration and shock according to IEC standards.

Installation Guide

Installing the STBNIP2311 is a straightforward process. First, mount the module onto a 35 mm DIN rail within the Advantys STB island assembly. Next, connect the 24V DC power supply to the designated terminals. Then, attach the Ethernet cables to the dual RJ45 ports as required by the network topology.

Configuration requires a few important steps. Specifically, set the module's IP address using BootP/DHCP or the embedded web interface. After that, configure the I/O modules within the STB island. The removable memory card simplifies configuration transfer between islands. Finally, verify all LED indicators to confirm proper operation.
