NAME

Device::Opto22 - Perl Object to communicate with Opto22 Brains via Memory-mapped protocol

SYNOPSIS

use Device::Opto22;

my $brain_ip = '192.168.1.7';

my $sock  = new Device::Opto22( PeerAddr => "$brain_ip",PeerPort => '2001' );

my $rtn = $sock->send_PUC();

# Read Opto22 scratch pad tables
my $int_table_sz = 15;     # number of entries to read in integer scratch pad table
my $flt_table_sz = 18;     # number of entries to read in float scratch pad table

my @int_lst = $sock->get_scratchpadint($int_table_sz);

my @flt_lst = $sock->get_scratchpadfloat($flt_table_sz);

DESCRIPTION

This Module communicates with an Opto22 Brain/Controller via OptoMMP a memory-mapped protocol based on the IEEE 1394 standard. This module can be used to create custom software applications for remote monitoring, industrial control, and data acquisition using Opto modular components

Methods include:

• get_scratchpadint - Get Integer Scratchpad

• get_scratchpadfloat - Get Floating Scratchpad

• get_eu_lst - Get Analog Bank Data in Engineering Units

• get_digital_lst - Get Digital Bank Data

• wr_digital_pnt - Write digital point

• serial_chat - Send received data to serial module

Note: The Opto22 Brains are in Big-endian format. The module translates this into common Little-endian format. If you are trying this module out on a Big-endian machine you will need to edit the source code as required.

EXPORT

None by default.
