1: Introduction

The IAP Family of Device Servers

The Lantronix Industrial Automation Platform (IAP) family of Device Servers allows a

single network and protocol to connect multiple serial devices from many vendors. IAP

provides the automation industry with a network-enabling solution using TCP/IP and

standard Ethernet networks that is vendor-independent.

By encapsulating serial data and transporting it over Ethernet, the Device Server allows

virtual serial links tobe established over Ethernet and IP networks. As a result, direct serial

connections can be extended within the plant, throughout the facility, and across the global

enterprise.

Existing COM-port-based WindowsTM applications can access network-enabled serial

devices, using Comm Port Redirector TM software. Redirector allows the creation of virtual

serial ports, which can be mapped to remote Device Servers over Ethernet. When used in

conjunction with an OPC server, most Windows based HMI, SCADA, and PC based

control applications have full access to information in the connected device.

Lantronix provides IAP Device Servers specifically designed for different industrial

environments:

CoBox-DR1-IAP, with a DIN rail interface for harsh environments or alongside

controls instruments in electrical panels.

CoBox-FL-IAP, with fiberconnectivity for long cable runs orelectrically hazardous

environments.

UDS-10-IAP, a compact design Device Server for use in less demanding

environments.

Key Features Introduction

A few examples of attached devices are:

PLCs

AC/DC drives

CNC systems

Operator panels and message displays

Process Controls

Instrumentation

Power monitoring equipment

Scales and weighing systems

Barcode scanners

Label printers

Most factory floor serial devices

Key Features

IAP Device Servers, adapted to the three factory environments, will unite any mixture of

equipment from industrial automation vendors into a single reliable pipeline. This new and

open infrastructure opens the way for data to flow in real time from all your plant devices

up to your IT layer.

The IAP Device Servers feature installable industrial communication protocols.

Lantronix’s Automation Protocols Suite (APS) includes protocols such as DF1 (Rockwell

Automation) and Modbus (Schneider Electric). Where the Standard Tunneling protocol is

limited to exclusive, device-to-device connections, the industrial protocols offer

connections to other devices simultaneously.

You can configure the unit using the serial port, or remotely over the network using Telnet

or a web browser. The APS CD (the CD that comes with your Device Server) includes

Windows-based configuration software that simplifies the process of installing protocols

and configuring them for use with attached devices. Flash memory provides for

maintenance free, non-volatile storage and allows system upgrades.

Introduction Network Protocols

1-3

Network Protocols

Device Servers use IP protocols for network communications. The supported protocols are

ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, HTTP, SNMP, and BOOTP. For

connections to the serial port, TCP, UDP, or Telnet protocols are used. Firmware updates

can be performed using TFTP.

The Internet Protocol (IP) defines addressing, routing, and data block handling over the

network. The Transmission Control Protocol (TCP) assures that no data is lost or

duplicated, and that everything sent to the connection arrives correctly at the target.

For typical datagram applications in which devices interact with other devices without

maintaining a point-to-point connection, User Datagram Protocol (UDP) is used.

Packing Algorithms

Two firmware selectable packing algorithms define how and when packets are sent to the

network. The standard algorithm is optimized for applications in which the Device Server

is used in a local environment, allowing for very small delays for single characters while

keeping the packet count low. The alternate packing algorithm minimizes the packet count

on the network, and is especially useful in applications in a routed Wide Area Network

(WAN). Adjusting parameters in this mode can economize the network data stream.

Ethernet (MAC) Address

The Ethernet address is also referred to as the hardware address or the MAC address. The

first three bytes of the Ethernet Address are fixed (e.g., 00-20-4A), identifying the unit as

a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each

Device Server.

Figure 1-1: Sample Ethernet Address

Internet Protocol (IP) Address

Every device connected to an IP network must have a unique IP address. This address is

used to reference the specific Device Server.

Port Numbers

Every TCP connection and every UDP datagram is defined by a destination IP address and

a port number. For example, a Telnet application commonly uses port number 23. A port

number is similar to an extension on a PBX system.

2: Installation

This chapter describes the CoBox-FL-IAP and shows how to install it on a basic network.

Product Description

Network Interface

The CoBox-FL-IAP’s network panel contains a 9-30VDC or 9-25VAC power plug, four

LEDs, an ST-Fiber (10BASE-FL) Ethernet port, and an RJ45 (10BASE-T) Ethernet port.

Both Ethernet ports support 10 Mbps and are auto detecting.

Note: Do not attempt to connect both Ethernet ports simultaneously. If one

is used, the other is disabled.

Serial Interface

The CoBox-FL-IAP’s serial panel contains two serial ports and three LEDs.Port (Channel)

1 is a female DB25 (DCE) that supports RS-232, RS-485, and RS-422 serial standards

(firmware selectable) up to 115.2 Kbps. Port (Channel) 2 is a male DB9 (DTE) that

supports RS-232 only. LED functionality is described in Table 2-2.

Installing the CoBox-FL-IAP

The following connection diagram shows a typical CoBox-FL-IAP used to attach serial

devices to a network.

Figure 2-3: CoBox-FL-IAP Connected to Serial Device and Network

To install the CoBox-FL-IAP, complete the following steps in order. Refer to the numbers

in the previous figure.

1Connect a serial device to the CoBox-FL-IAP. See Appendix F, Pinouts, for more

information about the kinds of device attachments the CoBox-FL-IAP supports.

2Connect a second serial device to the CoBox-FL-IAP (optional).

3Connect an Ethernet cable to either the 10BASE-FL OR the10BASE-T Ethernet

port. When connecting to the 10BASE-FL, connect the receiving cable to the Rx

port and the transmitting cable to the Tx port.

Note: Do not attempt to connect both Ethernet ports simultaneously. Only

one Ethernet connection can be made at any one time.

4Supplypower to the CoBox-FL-IAP using the power supply thatwas included inthe

packaging.

Note: The required input voltage is 9-30VDC or 9-25VAC.

Simultaneously lit red and green LEDs means something is wrong. If the red LED is lit or

blinking, count the number of times the green LED blinks between its pauses. Eight blink

patterns indicate which fault condition exists. The following table explains the functions of

the three serial LEDs
