Description of 1747-L514
The Allen-Bradley 1747-L514 is a SLC 500 processor. This module is
part of the modular style hardware that is installed in slot 0 of
the 1746 chassis. It features a 4K memory and built-in DH485
communication interface. This processor has a backplane current
draw of 0.090 A at 5VDC. It supports up to 3 I/O chassis and
maximum of 30 slots.
The Allen-Bradley 1747-L514 is an SLC 500 processor unit. This
module is also termed as an SLC 5/01 controller which is a single
slot width controller. It mounts to the slot 0 of any 1746 modular
chassis. It comes with a 4K user memory and embedded DH-485
communication interface.
The 1747-L514 is designed for use in small and medium automation
requirements. It is capable of controlling a maximum number of 30
I/O modules which can be distributed up to a maximum of 3 1746
chassis. It supports implementation of extended I/O and remote I/O
chassis using a variety of supported communication adapter by this
SLC 500 controller.
The 1747-L514 has an electrical current load of 0.090 at 5VDC. It
has a minimum power consumption of 1.75 Watts. The embedded DH-485
port supports use of the 1761-NET-AIC or the Advanced Interface
Converter (AIC) module. Additionally, the memory tables of the SLC
5/01 is accessible using the Allen-Bradley Data Table Access module
(DTAM).
The 1747-L514 may be installed with an optional non-volatile
memory. Non-volatile memory are in the form of Electrically
Erasable Programmable Read-Only Memory (EEPROM). Compatible EEPROM
are 1747-M1with 1K User Words EEPROM, 1747-M2 with 4 K User Words
EEPROM with a 1747-M5 memory module adapter socket. EEPROM modules
may be used to burn programs stored in the built-in memory which is
a Random Access Memory (RAM). By burning program to the
non-volatile memory, user program may be automatically loaded once
the controller is power cycled.
It uses the 1747-BA lithium battery assembly with a 30-minute
capacitor life and a lithium battery with a 2-year lifespan for
backup power for the standard RAM. The 1747-L514 has a maximum bit
execution time of 4µs and an overall module scan time of 8ms/K.
During a temporary power loss, the program scan on the module can
take from 20ms to 3s depending on the power supply that is loading.
It comes with a base DH-485 communication capability which can only
act in a slave capacity (Receiving) in the programming channel. The
1747-L514 has an ambient operating temperature range of 0-60°C
(32-140°F) at 5-95% non-condensing relative humidity range, and it
is designed to sustain an operational shock of 30G, and a vibration
of 2.5G at 57-2000Hz. The 1747-L514 is C-UL, UL, and CE-certified,
and it offers a NEMA standard ICS 2-230 industrial noise immunity.
About 1747-L514 Ser B
The 1747-L514 Series B processor is an Allen-Bradley SLC 500
processor. This processor features up to 960 maximum I/O points
with 480 analog I/O points while the user memory can store up to
4000 instructions. The 1747-L514 Series B processor has a program
scan time rating of 8 milliseconds. The recommended operating
temperature range is from 0 to 60 degrees Celsius while the
backplane current is rated at 105 milliamps at 24 Volts DC voltage
and it is rated 350 milliamps at 5 Volts DC voltage. The 1747-L514
Series B processor features the DH-485 communication protocol and
the backup memory that is an EEPROM unit. The unit features up to
30 chassis module slots with 3 I/O chassis and the I/O scan time is
rated at 2.6 milliseconds.
All of the data that the 1747-L514 Series B processor examines or
changes is normally stored in files in the data storage areas of
the memory unit. The storage areas keep the data that is received
from the input modules and the data that is going to be sent to the
output modules and that represents the decisions made by the logic.
In addition, the memory stores the intermediate results made by the
logic and the preloaded data, including the presets and the
recipes. The users can create the program files for the program
logic that is specialized depending on the method that is used. The
common programming methods include ladder logic programming,
sequential function charts programming, and structured text
programming. The 1747-L514 Series B processor program files contain
the instructions that examine the inputs as well as the outputs and
the return results.
