Theory of Operation

4.1 INTRODUCTION

This section describes the theory of operation of the 9009 and the 9099 Ethernet

to Modbus RTU interfaces. The description of the 9099 applies to the 9009

unless otherwise stated.

4.2

FUNCTIONAL DESCRIPTION

The 9099 is a microprocessor based device that performs the VXI-11 service,

raw socket service, Modbus TCP/IP conversion and webserver functions to

control its Serial Interface and connected Modbus RTU slave devices from

an IEEE-802.11 network. The 9099 is a microprocessor based device with

LXI compatible firmware. The different services can simultaneously access

multiple Modbus slave devices.

Incoming Ethernet messages are received by the LAN Interface chip. If the mes-

sage is a Modbus command then it is converted into a series of binary characters

to make up the Modbus RTU message packet. The Modbus message packet,

shown in Figure 4-1, includes the slave device address, the command number,

the registers and data (if any) that is being sent to the registers. A checksum is

added to make up the complete Modbus RTU packet. The Modbus packet is

then placed in the serial transmit buffer and outputted at the serial interface.

Packet Format: Addr Cmd Registers.... .data CRC

Figure 4-1 Modbus RTU Packet

If the message is a Modbus TCP/IP packet, the internal data from the packet is

combined with the slave device address to create the Modbus RTU packet. A
