1 Overview
The SCADAPack LP is a low power controller complete with an integrated power supply, analog
and digital I/O, serial communications and turbine flow meter counter inputs. See
Figure 1: SCADAPack LP Controller. Application programs can be written in Relay Ladder Logic,
IEC 61131-3 and the C language.
Several power saving features are included in the SCADAPack LP. These power saving features
include Sleep Mode, 24V-power shutdown, communication port power control and SCADAPack
Vision power down.
The SCADAPack LP has six analog input channels. Five analog inputs are user configurable for
either 10V or 20mA operation and one is a 32V analog input. Two optional 20mA analog outputs are
available.
Eight digital I/O points, each capable of sinking 1A or monitoring a dry contact closure, provide
flexible digital input and output configurations.
Three counter inputs, two of which are designed for direct connection to the millivolt output of
turbine meter transducers, provide for a variety of connections to metering elements.
The I/O capacity of the SCADAPack LP can be expanded using 5000 Series I/O modules. A
maximum of forty 5000 Series I/O modules may be used for a total expansion capacity of 512 digital
inputs, 512 digital outputs, 128 analog inputs, 64 analog outputs and 64 counter inputs.
Three serial communication ports are provided. An RS-485 port is designed for use with
multivariable transmitters. One of the two RS-232 ports is designed for use with the SCADAPack
Vision operator interface. The SCADAPack LP supports direct wired, telephone and radio
communication.
The primary microcontroller memory is 512KBytes flash ROM, and 1MBytes RAM. The CMOS
RAM is non-volatile (battery backed). An EEPROM (1kBytes) stores configuration parameters. A
real time clock calendar provides for time of day operations and alarms. A hardware watchdog timer
protects against application program failures.
