APPLICATIONS

GENERAL DESCRIPTION

The OpenLT

slave that responds to Optomux

from the master or host PC. The 72-OPT-4100

version has memory for Embedded Control

Programs (ECPs) which are control or data

acquisition routines which run locally on the

OpenLT

from the host. ECP routines written for MicroDAC

can be easily transferred to OpenLT

versa. By combining MicroDAC, OpenLT

ProMux

control or data acquisition network is optimized

for price and performance.

Analog and/or Digital I/O using OpenLine

Modules

Any combination of OpenLine

I/O modules may be used. OpenLTs

networked to a host PC which execute programs

that monitor the input signals and control the

outputs. In addition to simple ON/OFF

instructions, commands are included which

permit you to:

• Sample analog signals at 2 mS per input

• Flag values above or below prescribed levels

• Capture min/max values

• Calculate the average input signal levels

• Provide linearized thermocouple and

• Determine the width of input pulses

• Count pulses at frequencies up to 1000Hz

• Detect rising or falling edges

• Latch momentary input events

• Set the level of analog outputs

• Provide delayed-on or delayed-off outputs

COMMUNICATIONS

The host computer and OpenLT(s)

communicate serially over one or two pair of

twisted wires per RS-422/485 in a multi-drop

configuration. They use Optomux

to code the command and the response

messages. Application programs running on

the host computer issue commands and then

await responses from the OpenLT

communications speed is selectable between

9.6 and 115.2 KBaud. Each controller on the

network is assigned a unique base address.

The entire network can span 4000 feet.

Diagnostic LEDs show traffic on the network.

RTD temperature values

EMBEDDED CONTROL PROGRAMS

By specifying OpenLT(s)

KB of flash memory, you can develop and

download C language programs to any of the

networked controllers.

Even while an ECP is running on OpenLT

Optomux

will be processed as usual, which allows you to

delegate some or all of the control and data

acquisition responsibility from the host computer.

This reduces communications time and improves

system response.

For embedded or stand-alone applications,

downloaded ECP routines can be initiated on

power-up.

Libraries and the appropriate download utility

are included with the ECP Programmers Manual.

SOFTWARE

Software drivers are available which simplify

the task of interfacing host programs written in

Visual Basic or C to the Optomux network.

Sample programs, set-up and debug utilities

are included on the disk with the drivers. Interface

drivers for most third party software packages

are available through their distributors. Our

Optomux DDE Server dramatically simplifies

data sharing between OpenLTs

applications, such as Microsoft EXCEL (see

Controller Software). Our DLL will assist you in

building custom Windows Man-Machine

Interfaces using Visual Basic, Visual C/C

Borland compilers.
