1.0 Purpose

This document describes how to get started with the SEC 3500 Operator Interface
(OI) Panel. It describes the basics of discovering SEC Modbus 485 devices, and the basic
startup configuration. This document is NOT a detailed all-encompassing Startup, Basic
Operator, Supervisor or Technical User's Manual. This manual is part of a documentation
pack that contains all necessary information for using, starting up, configuring and
enabling higher-end functionality, and is the first manual in the pack necessary for getting
started.

2.0 Overview

The SEC 3500 OI Panel drives and masters the SEC 3500 Modbus 485 Digital
Gas Monitoring Loop, based on the loop-attached SEC 3100 Digital Gas Transmitter
slaves. It draws information from all SEC 3100 Digital Gas Transmitters on the loop into
a single location, where all information is accessible and configurable. In addition, it adds
features for controlling separate SEC Modbus 485 Relay modules, allowing a central
coordinated command and control center for a given loop.
The SEC 3500 OI is a self-contained standalone intelligent touch-screen Human
Machine Interface (Operator Interface Panel). It contains various communication ports
for RS485 communications, RS232 Gas Status Text Dumps, and 10/100mb Ethernet for
Web-based services. It also contains a compact flash card socket for software updates and
data logging. It operates on 24vdc, and permanently stores its program and non-volatile
data in internal flash memory- There are NO disk drives.
