The AB 1747-L532 is an SLC 5/03 Processor that is a part of the SLC 500 system. It is a small, simple, and pocket-sized processor
with a wide range of applications such as small process control, material handling, and HVAC control. It contains a PLC-5 processor-based
advanced instruction set. It can be stand-alone or distributed throughout a system for SCADA applications.

The 1747-L532 processor has a total user memory of 16K words with 12K words for data/program and 4K words for data alone. It has up to
4096 inputs, 4096 outputs, and 480 local analog I/Os. It has a program scan time per keyword of 1 millisecond. The 1747-L532 has a backplane
current of 500 mA at 5 Volts DC and of 175 mA at 24 Volts DC. It has a maximum of 2 local I/O chassis with a maximum of 30 module I/O slots
in a local I/O chassis.


For communication, it uses DH-485 and RS-232 ports that can be configured for connection to a 1761-NET-AIC converter. For programming,
the 1747-L532 it supports RSLogix 500 software. It has standard battery-backed RAM and Flash backup memory. With this processor, the
remote I/O scanner module and DeviceNet scanner module can be installed to configure I/O via a universal remote link or a DeviceNet network.

The 1747-L532 processor provides 0.44 milliseconds bit-instruction execution time and 10 times the overall system that its competitors do.
It has various additional capabilities such as online programming, flash memory upgrades, floating-point math, a built-in real-time clock,
key-switch, and calendar. The 1747-L532 is intended for use in clean and dry industrial environments with a 0 to 60 degrees Celsius operating
temperature and a 30G of operating shock.


The 1747-L532 Programmable Logic Controller (PLC) is an SLC 500 processor that is also known as SLC 5/03 controller. This controller is
designed for use with the Modular Style SLC 500 series that is manufactured by AB. This specific controller is capable of
implementing basic and advanced instructions that allows any user to construct a simple user program to complex control logic.

These instructions include Bit, Timer, Controller, Comparison, Basic Math, Move, Copy, and Bit Shift, Sequencer, Jump and Subroutine,
Messaging, STI, FIFO/LIFO, PID, Advanced Math and Trig instructions.


The integrated communication port of this controller is a single RS232 port that can be configured as DF1 or DH485, both for peer-to-peer
applications. The default configuration of the RS232 is DF1 Full-duplex, handshaking disabled, communication rate of 19.2Kbaud, CRC Error

check, duplicate packet detects on and parity set to none. It may also be auto-detected in the RSLinx communication tool through the
auto-config driver mode. The default settings of Channel 1 DH485 port are 19.2 Kbaud and node address = 1.


The integrated memory of this SLC 5/03 processor is 16KB. This controller supports burning of program to a back-up memory to allow automatic
loading of user program upon power cycle. This prevents unwanted deletion of PLC program when the integrate 1747-BA is drained.
This Battery is provided with a LED indicator to indicate the state of the battery’s power.


This controller is configured using RSLogix 500 programming software which is the common programming software for the SLC 500 product
family.
