About Processor Unit module 1747-L553
The 1747-L553 is an SLC 5/05 processor that belongs to the SLC 500
Programmable Logic Controller (PLC) platform. This controller has
the highest memory among the SLC 5/05 category which is 64 KB
memory. It has integrated RS32 Sub-D 9-Pin connector for
establishing peer-to-peer communication with locally installed
Human Machine Interface (HMI) or a programming workstation. It also
has an integrated Ethernet that is ideally used for communication
over a long distance, minimum of 100 meters at 10/100 mbps
transmission speed. It is also ideal for establishing connection to
multiple devices at a time. These Two (2) port may also be used
simultaneously without affecting the processor’s logic execution
capability.
This controller is ideal for medium to large scale application,
with control requirements ranging from manual to automatic control
of Discrete or analog loops as well as implementing complex control
techniques with the utilization of a wide number of embedded
instructions. It may be used in Factory automation, Process
Automation even in motion and position control requirements.
It is also capable of sending Messages to other AB PLC platforms
such as PLC 5, CompactLogix and ControlLogix via a specified
communication protocol. Though integrated with Ethernet and RS232
ports, this processor may be installed with communication adapters
such as Remote I/O (RIO), Data Highway Plus (DH+), DeviceNet and
DH485.
It may be installed to any SLC 500 chassis. This processor module
has a fixed slot assignment of slot Zero (0).
It contains a PLC-5 processor-based advanced instruction set. The
1747-L553 can stand alone or be distributed throughout the system
for SCADA applications. The 1747-L553 processor has a total user
memory of 64K words with 60K words for data/program and 4K words
for just data. It has up to 4096 inputs, 4096 outputs, and 480
local analog I/O. It has a program scan time per keyword of 0.9ms
and 0.225 milliseconds I/O scan time. The 1747-L553 has a backplane
current of 1 Amp at 5 Volts DC and 0 Amps at 24 Volts DC. It has a
maximum of 3 local I/O chassis with maximum 30 module I/O slots in
local I/O chassis.
For communication, it uses Ethernet and RS-232 ports that can be
configured for connection to the 1761-NET-AIC converter. It has
standard battery-backed RAM and Flash backup memory. With this
processor, Remote I/O Scanner module and DeviceNet Scanner module
can be additionally installed to configure I/O via Universal Remote
link or DeviceNet network. The 1747-L553 processor provides shorter
bit-instruction execution time of 0.37 milliseconds and 10/100 Mbps
Ethernet port. Its DH+ communication port is 3 times faster than
the DH-485 port. It has all the features of other SLC 5/03
processors like online programming, flash memory upgrades,
floating-point math, and a built-in real-time clock, key-switch,
and calendar. The 1747-L553 is intended for use in clean and dry
industrial environments with a 0 to 60 degrees Celsius operating
temperature and a 30G operating shock.
