INTRODUCTION

The DANIEL INDUSTRIES MODEL 2500 INSTRUMENTATION SYSTEM
MICROCOMPUTER is an advanced state-of-the-art, microprocessor-based
computer used to control and measure the numerous physical and dynamic
characteristics of fluids, such as liquids and gases. Compatible with most process
flowmeters and transmitters, the MODEL 2500 is a state-of-the-art instrument with
both a large input/output capacity and a powerful processor possessing the
programmable capabilities necessary for the hundreds of applications required for
a demanding environment.

The DANIEL INDUSTRIES MODEL 2500 software can be configured to:

- Perform a broad range of flow measurement and process applications

without compromising the exact needs of the application and without

the expense of a custom instrument.

- Monitor and read live transmitter inputs, both analog and digital.

- Produce multiple calculated outputs.

- Act as a controller for meter prover applications.

- Serve as a Remote Terminal Unit (RTU) furnishing calculated data on

demand to a "Host" computer or a Supervisory Control and Data

Acquisition (SCADA) system.

MODEL 2500 HARDWARE

The DANIEL INDUSTRIES MODEL 2500 INSTRUMENTATION SYSTEM
MICROCOMPUTER hardware comes in either a one-board system or a two-board
system. Both systems function identically with the same baseline and software.
The number of inputs and outputs required by the user will dictate whether a one­or a two-board system is needed.

Refer to Figures 1-1 and 1-2 for a graphic depiction of the differences between the
two systems. For more detailed specifications, refer to the MODEL 2500
Microcomputer Hardware Manual, Daniel P/N 3-9000-590.

MODELMODEL 25002500 SOFTWARESOFTWARE

The DANIEL INDUSTRIES MODEL 2500 specialized application software is
developed in conjunction with the CONFIG25 program. The CONFIG25 program
is designed to run on an IBM PC or compatible personal computer.

This manual provides the basic operational information to download and operate
software in the MODEL 2500, which contains a Revision 5.00 level or higher. The
new generation of BASE25 allows the user to download any Revision K.2 or
higher applications without requiring a new analysis of an application under a
different Config25.

Prior to Revision 5.00 baseline, applications had to be developed, analyzed, and run
on software that was of the same revision level. Revision 5.00 and higher
firmware (hereafter referred to as 5.nn), is designed to support applications
developed on multiple Daniel CONFIG25 software releases.

The following table lists the CONFIG25 software releases that are supported and
the baseline used for execution. The following compatibility rules are imposed by
the download routine.

ability to enter and change data and system commands. The keypad is located
approximately in the center of the panel, and is symmetrically arranged in four
columns of four keys each.

Ten of the 16 keys are marked with the numbers 0 through 9, arranged in
descending order. The remaining keys are marked with a decimal point, a minus
sign, an UP arrow, a DOWN arrow, and the command words of EXIT and ENTER.

The UP arrow, DOWN arrow, EXIT and ENTER keys have been assigned specific
functions. The keys and their functions are defined below:

UP/DOWN
Arrow Keys Sequences the front panel display forward or backward

through a menu or sub-menu. The display can be
changed one step at a time by depressing a key
repeatedly, or it can be sequenced rapidly by holding
down a key.

EXIT Key Moves the display to the next higher menu.

MODEL 2500 REMOTE FRONT PANEL

The DANIEL INDUSTRIES MODEL 2500 INSTRUMENTATION SYSTEM
MICROCOMPUTER remote front panel is an external terminal connected to the
MODEL 2500 by means of a serial port. The same functions that are possible on
the front panel of an on-site MODEL 2500 are also possible with the remote front
panel. However, only one front panel may be active at a given time.

Activation of the remote front panel is made possible by assigning it to a serial port
using one of the PORTUSE selections in the Serial Ports sub-menu. Control is
returned to the front panel of the on-site unit from the remote front panel by
changing the PORTUSE selection to an option other than the remote front panel.

Selecting the remote front panel or returning control to the front panel of the
on-site unit may take as long as 30 seconds before the operation is complete. The
remote front panel responds more slowly than the front panel of the on-site unit to
both keyboard entry and display refreshing.

When the remote front panel is selected, the LCD screen of the on-site unit
displays the following message:

REMOTE FRONT

PANEL SELECTED

_________________________________________________________

NOTE! If the remote front panel fails when the remote unit is

in control or if for some other reason, communications
is lost between the on-site unit and the remote front
panel, control can be returned to the front panel of the
on-site unit by simultaneously pressing the zero,
decimal, and minus keys.

INITIALIZING SEQUENCE

After power is applied to the DANIEL INDUSTRIES MODEL 2500
INSTRUMENT SYSTEM, it automatically performs an initializing sequence,
whether the startup is considered to be a "cold" or "warm".

In a "cold" startup, power is switched on to the MODEL 2500, and the initializing
sequence:

- Determines if the instrument is configured for a specific application

- Performs a series of self-diagnostic tests

The self-diagnostic tests ensure that all internal circuitry and devices in the
instrument are operational.

In a "warm" startup, which occurs after the power supply has been briefly
interrupted or a "watchdog" message has indicated a problem in the program, the
initializing sequence, again:

- Determines if the instrument is configured for a specific application

- Performs a series of self-diagnostic tests

During a "warm" startup, the front panel displays a copyright message and
copyright date for several seconds before performing the initializing sequence.
However, during a "cold" startup, the copyright message does not appear.
