About 1747-L531
The AB 1747-L531 is an SLC 5/03 processor type module that belongs
to the SLC 500 Modular Hardware Style series.
It is built to perform a large variety of functions, including
small, simple stand-alone systems to large, complex distributed
ones.
Designed to perform throughput, it can support 60 various I/O
modules including analog, digital, and intelligent I/O’s and can,
in addition,
control up to 4,096 output and input points. It ships with the SLC
500 modular processor, a compatible chassis, power supplies, and
installation
instructions for all the included parts. This module is C-Tick
marked, CE compliant, and UL listed to Canadian and US Safety
Standards,
The 1747-L531 Modular Processor comes with a memory size of 8 K, 16
K, or 32 K for its programs. This user-configurable memory can be
applied either to program storage or to data storage. The drive
features a battery-backed RAM that lasts approximately 2 years.
The BATT LED indicator alerts user when the voltage of the
replaceable battery has fallen below the threshold level. A minimum
of thirty (30)
minutes of power is available when the battery is disconnected, due
to an integrated capacitor. If a new battery is installed to
replace the old
one within half an hour (30 minutes), any data stored in the RAM
can be retained. The 1747-L531 Processor receives and initiates
communication protocols including DH-485 peer-to-peer, ControlNet,
Ethernet, Data Highway Plus (DH+), DeviceNet, Modbus RTU Master,
as well as full-duplex or half-duplex master or slave DF1, ASCII
and DH-485 via the RS232 port. Its front panel has a 3-position key
switch that
allows three operation modes: PROGRAM, RUN, and REMOTE. This key
switch cannot be used in place of an emergency-stop switch or a
hardwired master control relay.
This controller has an integrated 8K memory, which can be expanded
with the use of a Flash EPROM. The required memory module has part
number of 1747-M13 and adapter socket of 1747-M15 that supports up
to 64K of user memory. User program can be stored or burned to the
memory module to prevent accidental or unwanted program deletion
that may be caused by improper programming, electrical surges and
noises. The general rule when burning user program to the memory
module is that the program size must not exceed the processor
memory
size. Do not burn a faulted program, especially a program with a
major fault. This will include the fault condition and cause of the
fault to be
burned in the EPROM.
All SLC processors are configurable using RSLogix 500 Programming
software. This software is a ladder programming software.
User programs, hardware configuration are implemented here as well
as commissioning and troubleshooting tool are available such as I/O
forcing. The integrated RSLinx communication setup tool is RSLogix
500’s communication driver for various AB products, to establish
communication to and from the controller.
This processor also supports hold-up time feature. This refers to
the processor’s ability to continue programming scanning for a
limited time
even if the input voltage to the system power supply falls below
the nominal range. When the hold-up time expire, the CPU is
automatically put
to stop mode. This prevents sudden stoppage that is not ideal in
any control application.
