Schneider STBNDP2212 Advantys STB Network Module

Schneider STBNDP2212 Advantys STB Network Interface Module

Product Introduction

The STBNDP2212 serves as the network gateway for Schneider Electric Advantys STB distributed I/O islands. Specifically, this standard network interface module connects field I/O to a PROFIBUS DP network. It presents the entire island as a single PROFIBUS slave node, which simplifies controller integration.

This standard version adds more capability than the basic NIM in the same family. For instance, it supports larger and more demanding island configurations. Furthermore, it keeps cabinet wiring short and reduces overall installation cost.

Communication and Protocol Support

The STBNDP2212 module delivers dependable fieldbus communication. It features one 9-pin SUB-D connector, specifically a DB-9S female port. Additionally, it communicates using the PROFIBUS DP protocol at standard fieldbus rates.

This network interface module supports up to 32 I/O modules within one island. Therefore, it handles a broad mix of digital and analog I/O combinations. Besides process data exchange, the NIM reports island diagnostics to the master. Meanwhile, correct termination, shielding, and cable routing remain essential for stable PROFIBUS communication.

Electrical Specifications and Power

Power requirements for the STBNDP2212 are straightforward. It operates on a 24V DC supply voltage. Moreover, the module distributes logic power to the I/O modules across the island backplane.

Installers should confirm the total island current draw before commissioning. In addition, a stable 24V DC supply and proper grounding improve long-term reliability. However, detailed current and logic bus output figures are not published for this standard NIM.

Mechanical and Environmental Parameters

The STBNDP2212 uses a compact housing for dense control cabinets. Its dimensions measure 128.3 mm in height, 70 mm in width, and 40 mm in depth. The module weighs approximately 0.145 kg. It mounts easily on a standard 35 mm DIN rail.

Environmental specifications support general industrial use. The protection rating is IP20, which suits clean and controlled environments. Operating and storage temperature data are not published for this module. Therefore, keep the installation within the cabinet conditions recommended for the Advantys STB island.

Installation Guide

Installing the STBNDP2212 follows a clear sequence. First, mount the module onto a 35 mm DIN rail inside the Advantys STB island assembly. Next, connect the 24V DC power supply to the correct terminals. Then, attach the PROFIBUS cable to the DB-9S port.

Network setup requires a few important steps. Specifically, set the PROFIBUS station address using the module switches or software tool. After that, configure the I/O modules within the island. Finally, verify the status indicators and run a communication test with the master.

FAQ

Q1: What is the main role of the STBNDP2212?
The STBNDP2212 connects an Advantys STB I/O island to a PROFIBUS DP network. It represents the island as one PROFIBUS slave node.

Q2: Which protocol does this NIM support?
This module supports the PROFIBUS DP protocol. It provides a single 9-pin SUB-D (DB-9S) port for the fieldbus connection.

Q3: How many I/O modules can this island support?
The STBNDP2212 can address up to 32 I/O modules per island. This covers a broad mix of digital and analog modules.

Q4: What power supply does the module need?
It requires a 24V DC supply. The module then distributes logic power to the I/O modules on the island backplane.

Q5: Is the STBNDP2212 still in production?
This module is discontinued and superseded by the Modicon X80 range. However, it remains available through industrial automation suppliers for maintenance and legacy support.
