About the Book

At a Glance

Document Scope This Guide describes the hardware and software features of the Advantys

STB NIP 2212, which enables an island of Advantys STB modules to function as a node on an Ethernet LAN. The Ethernet LAN on which an island resides uses Transport Control Protocol/ Internet Protocol as its transport layer. The Modbus protocol runs over the TCP/IP layer. This way, an Ethernet host device can control an island with Modbus commands. The Modbus protocol allows devices that can connect only to the RS232 port on other Advantys STB NIMs to connect to the STB NIP 2212’s fieldbus port, too. The following information appears in this guide:

the role of the standard NIM as the gateway between Ethernet TCP/IP and the Advantys STB island

the NIM’s integrated power supply and its role in the distribution of logic power across the island bus

common external interfaces:

the two-pin connector to an external SELV-rated power supply

RS-232 interface to optional devices, including the Advantys configuration software and an HMI panel

the optional removable memory card

advanced configuration features, such as island fallback scenarios

STB NIP 2212 specific features, including its global connectivity capabilities

how to configure an STB NIP 2212 with IP parameters

how to connect the STB NIP 2212 to an Ethernet network

STB NIP 2212 web-based configuration and troubleshooting features

SNMP management services

Who Should Use This Manual?

This manual is intended to support the customer who has installed the Advantys STB island bus on an Ethernet LAN and needs to understand the STB NIP 2212’s local and remote communications capabilities. This manual assumes familiarity with the Modbus protocol.

Introduction

What Is a Network Interface Module?

Purpose Every island requires a network interface module (NIM) in the leftmost location of the

primary segment. Physically, the NIM is the first (leftmost) module on the island bus. Functionally, it is the gateway to the island bus—all communications to and from the island bus pass through the NIM. The NIM also has an integrated power supply that provides logic power to the island modules.

The Fieldbus Network

Communications Roles

An island bus is a node of distributed I/O on an open fieldbus network, and the NIM is the island’s interface to that network. The NIM supports data transfers over the fieldbus network between the island and the fieldbus master. The physical design of the NIM makes it compatible with both an Advantys STB island and your specific fieldbus master. Whereas the fieldbus connector on each NIM type may differ, the location on the module front panel is essentially the same. Other NIM connectors, such as the power supply interface and the CFG interface (See The CFG Interface, p. 33), are identical for all NIM types.

Communications capabilities provided on a standard NM include:

Function Role

data exchange The NIM manages the exchange of input and output data

between the island and the fieldbus master. Input data, stored in native island bus format, is converted to a fieldbus-specific format that can be read by the fieldbus master. Output data written to the NIM by the master is sent across the island bus to update the output modules and is automatically reformatted.

configuration services Custom services can be performed by the Advantys

configuration software. These services include changing the operating parameters of the I/O modules, fine-tuning island bus performance, and configuring reflex actions. The Advantys configuration software runs on a computer attached to the NIM’s CFG port.

human-machine interface (HMI) operations

An HMI panel can be configured as an input and/or output device on the island bus. As an input device, it can write data that can be received by the fieldbus master; as an output device, it can receive updated data from the fieldbus master. The HMI can also monitor island status, data, and diagnostic information. The HMI panel must be attached to the NIM’s CFG port.

Introduction

Integrated Power Supply

The NIM’s built-in 24-to-5 VDC power supply provides logic power to the I/O modules on the primary segment of the island bus. The power supply requires a 24 VDC external power source. It converts the 24 VDC to 5 V of logic power, providing 1.2 A of current to the island. Individual STB I/O modules in an island segment generally draw a current load of between 50 and 90 mA. (Consult the Advantys STB Hardware Components Reference Guide [890 USE 172] for a particular module’s specifications.) If the current drawn by the I/O modules totals more than 1.2 A, additional STB power supplies need to be installed to support the load. The NIM delivers the logic power signal to the primary segment only. Special STB XBE 1200 beginning-of-segment (BOS) modules, located in the first slot of each extension segment, have their own built-in power supplies, which will provide logic power to the STB I/O modules in the extension segments. Each BOS module that you install requires 24 VDC from an external power supply.

Introduction

What Is Advantys STB?

Introduction Advantys STB is an assembly of distributed I/O, power, and other modules that

function together as an island node on an open fieldbus network. Advantys STB delivers a highly modular and versatile slice I/O solution for the manufacturing industry, with a migration path to the process industry. Advantys STB lets you design an island of distributed I/O where the I/O modules can be installed as close as possible to the mechanical field devices that they control. This integrated concept is known as mechatronics.

Island Bus I/O An Advantys STB island can support as many as 32 I/O modules. These modules

may be Advantys STB I/O modules, preferred modules, and standard CANopen devices.

The Primary Segment

STB I/O modules on an island may be interconnected in groups called segments. Every island has at least one segment, called the primary segment—it is always the first segment on the island bus. The NIM is the first module in the primary segment. The primary segment must contain at least one Advantys STB I/O module and can support an I/O load of up to 1.2 A. The segment also contains one or more power distribution modules (PDMs), which distribute field power to the I/O modules.

890USE17700 April 2004 15

Introduction

Extension Segments

When you are using a standard NIM, Advantys STB I/O modules that do not reside in the primary segment can be installed in extension segments. Extension segments are optional segments that enable an island to be a truly distributed I/O system. The island bus can support as many as six extension segments. Special extension modules and extension cables are used to connect segments in a series. The extension modules are:

the STB XBE 1000 EOS module, which is the last module in a segment if the island bus is extended

the STB XBE 1200 BOS module, which is the first module in an extension

segment The BOS module has a built-in 24-to-5 VDC power supply similar to the NIM. The BOS power supply also provides 1.2 A of logic power to the STB I/O modules in an extension segment. Extension modules are connected by lengths of STB XCA 100x cable that extend the island communication bus from the previous segment to the next BOS module:

6 STB XBE 1200 BOS bus extension module for the first extension segment

7 another STB XBE 1000 EOS extension module

8 4.5 m length STB XCA 1003 bus extension cable

9 second extension segment

10 STB XBE 1200 BOS bus extension module for the second extension segment

11 STB XMP 1100 termination plate

Bus extension cables are available in various lengths, ranging from 0.3 m (1 ft) to

14.0m (45.9ft).

Introduction

Preferred Modules

An island bus can also support those auto-addressable modules referred to as preferred modules. Preferred modules do not mount in segments, but they do count as part of the 32-module maximum system limit.

Note: If you want to include preferred modules in your island, you need to configure the island using the Advantys configuration software.

A preferred module can connect to an island bus segment via an STB XBE 1000 EOS module and a length of STB XCA 100x bus extension cable. Each preferred module has two IEEE 1394-style cable connectors, one to receive the island bus signals and the other to transmit them to the next module in the series. Preferred modules are also equipped with termination, which must be enabled if a preferred module is the last device on the island bus and must be disabled if other modules follow the preferred device on the island bus. Preferred modules can be chained to one another in a series, or they can connect to Advantys STB segments. As shown in the following figure, a preferred module passes the island bus communications signal from the primary segment to an extension segment of Advantys STB I/O modules:

Introduction

Standard CANopen Devices

You may also install one or more standard CANopen devices on an island. These devices are not auto-addressable, and they must be installed at the end of the island bus. If you want to install standard CANopen devices on an island, you need to use an STB XBE 2100 CANopen extension module as the last module in the last segment.

Note: If you want to include standard CANopen devices in your island, you need to configure the island using the Advantys configuration software, and you need to configure the island to operate at 500 kbaud.

Because standard CANopen devices cannot be auto-addressed on the island bus, they must be addressed using physical addressing mechanisms on the devices. The standard CANopen devices together with the CANopen extension module form a sub -network on the island bus that needs to be separately terminated at the beginning and end. A terminator resistor is included in the STB XBE 2100 CANopen extension module for one end of the extension sub-network; the last device on the CANopen extension must also be terminated with 120 Ω. The rest of the island bus needs to be terminated after the CANopen extension module with an STB XMP 1100 termination plate:

Length of the Island Bus

The maximum length of an island bus—the maximum distance between the NIM and the last device on the island—is 15 m (49.2 ft). This length must take into account the extension cables between segments, extension cables between preferred modules, and the space consumed by the devices themselves.

Introduction

STB NIP 2212 Product Overview

Introduction An Advantys STB island bus configured with an STB NIP 2212 standard NIM can

function transparently as a node on an Ethernet local area network (LAN), or on the Internet. It can function, indirectly, as a node on a wide area network (WAN). The STB NIP 2212 can be a slave device to an Ethernet host manager.

Ethernet and Internet Connectivity

TCP/IP is the transport layer for the Ethernet LAN on which the STB NIP 2212 Advantys STB island resides. This network architecture enables communications with a wide range of Ethernet TCP/IP control products, such as Programmable Logic Controllers (PLCs), industrial computers, motion controllers, host computers, and operator control stations. The STB NIP 2212 NIM has a Transparent Ready implementation classification of B20.

Embedded Web Server

The STB NIP 2212 includes an embedded web server (See STB NIP 2212 Web Server, p. 65), which is a web browser-enabled application. It allows authorized

users worldwide to view configuration and diagnostic data for the STB NIP 2212 (See Web Access Password Protection, p. 86). (Users with additional authorization (See Configuration Password Protection, p. 89) can write data to the STB NIP 2212.)

Internet Applications

The STB NIP 2212 is configured for the following Internet applications:

HTTP embedded web server –Port 80 service access point (SAP) –browser based IP configuration and troubleshooting

SNMP—allows remote network management of the STB NIP 2212 –Port 161 SAP –enables remote network management (NMT) of the STB NIP 2212

Open Modbus An open implementation of the proprietary Modbus protocol runs over TCP/IP on the

Ethernet LAN on which the STB NIP 2212 resides. The fieldbus (Ethernet) port (See STB NIP 2212 Network Interface, p. 26) on the STB NIP 2212 is configured for Port 502 SAP functionality. Port 502 is the well-known port for Modbus over TCP that was assigned to Schneider Electric by the Internet Authority (IANA).

Introduction

Conformance to NIM Standards

The STB NIP 2212 is designed to support all of the standard Advantys STB NIM features and functions (See What Is a Network Interface Module?, p. 12). Because an STB NIP 2212 runs Modbus as its fieldbus protocol, a device running the Advantys configuration software or a human-machine interface (HMI) can attach to either its fieldbus (Ethernet) port) (See STB NIP 2212 Network Interface, p. 26) or its CFG port (See The CFG Interface, p. 33).

Ethernet Host PLCs and personal computers (PCs) configured with the Modbus protocol are

suitable upstream Ethernet hosts to islands using the STB NIP 2212 as their gateway. The Ethernet host can be local or remote.

Introduction

Ethernet Communications and Connectivity

Introduction The STB NIP 2212 allows the Advantys STB island to function as a node on an

Ethernet local area network (LAN). Ethernet is an open local (communications) network that enables the interconnectivity of all levels of manufacturing operations from the plant’s office to the sensors and actuators on its floor.

Conformance The STB NIP 2212 is located on a 10Base-T LAN. The 10Base-T standard is

defined by the IEEE 802.3 Ethernet specification. Contention for 10Base-T networks is resolved by using Carrier Sense Multiple Access with Collision Detect (CSMA/ CD).

Transmission Rate

An STB NIP 2212 island node resides on a baseband network with a transmission rate of 10 Mbit/s.

Frame Format The STB NIP 2212 supports both Ethernet II and IEEE 802.3 frame formats;

Ethernet II is the default frame type.

Modbus over TCP/IP Connection

The STB NIP 2212 limits the number of Modbus client connections to 32. If a request for a new connection is received and the number of existing connections is at the limit, the oldest unused connection is closed.

STB NIP 2212 Network Interface

Introduction The fieldbus interface on the STB NIP 2212 is the point of connection between an

Advantys STB island and the Ethernet LAN on which the island resides. This fieldbus interface is also called the Ethernet port. The fieldbus interface is a 10Base-T port with an RJ-45 female connector. Category 5 (CAT5) twisted pair electrical wiring, either shielded or unshielded (STP/UTP), is used to connect the STB NIP 2212 to the Ethernet baseband.

Note: Because the Ethernet port is configured for Modbus over TCP/IP services (SAP 502), the Advantys configuration software can run over the fieldbus interface on the STB NIP 2212.

Fieldbus (Ethernet) Port

The interface for 10Base-T connections is located on the front of the STB NIP 2212 NIM toward the top:

eight-pin connector

The RJ-45 connector is an eight-pin female connector. The eight pins connect horizontally along the top. Pin 8 has the leftmost position, and pin 1 is the rightmost. The pin-out for the RJ-45 complies with the information in the following table:

Rotary Switches

Introduction The STB NIP 2212 is a single node on an Ethernet LAN and, in turn, the Internet.

An STB NIP 2212 must have a unique IP address. The two rotary switches on the NIM provide a simple, easy way to assign an IP address to the STB NIP 2212.

Physical Description

The two rotary switches are positioned one above the other on the front of the STB NIP 2212. The upper switch represents the tens digit, and the lower switch represents the ones digit:

Summary of Valid IP Address Settings

Each rotary switch position that you can use to set a valid IP address is marked on the STB NIP 2212 housing (See Physical Description, p. 28). The following information summarizes the valid address settings:

For a switch-set role name, select a numeric value from 00 to 159. You can use both switches:

On the upper switch (tens digit), the available settings are 0 to 15.

On the lower switch (ones digit), the available settings are 0 to 9. The numeric setting is appended to the STB NIP 2212 part number, e.g., STBNIP2212_123, and a DHCP server assigns it an IP address.

For a BootP-served IP address (See Server-Assigned IP Addresses, p. 62), select either of the two BOOTP positions on the bottom switch.

If you set the bottom switch to either of the two INTERNAL positions, the IP address will be assigned by one of the following methods:

if the STB NIP 2212 is direct from the factory, it has no software set

IP parameters and will use a MAC-based IP address (See Deriving an

IP Address from a Media Access Control (MAC) Address, p. 61).

a fixed IP address using the STB NIP 2212 web configuration pages (See

Web-Based Configuration Options, p. 71)

a web-configured role name (See Configuring a Role Name, p. 82) in

association with a DHCP server

Note: For information about how the STB NIP 2212 prioritizes IP addressing options, refer to the IP parameterization flow chart (See Determining the IP Address, p. 63).

Note: The STB NIP 2212 requires a valid IP address to communicate on the Ethernet network and with a host. You must power cycle the STB NIP 2212 to configure the STB NIP 2212 with an IP address set with these rotary switches.
